For the 6th-7th? Temps are in the mid 40s. Even VT/NH are above freezing. Maybe Maine can pull it off again. I was looking at going skiing in either the Catskills or Mt Snow. I haven't gone yet this year and normally I'd really be jonesing to get a few days in. My son's back from college Wed-Fri and I'm really glad we didn't book anything. There will be fog, 2+" of rain and that's just not fun. Friday may open up but still warm. Don't think it will be worth the effort. Then rain again on Sat. 1 Link to comment Share on other sites More sharing options...

Hard to believe the Cats’ aren’t good early March , but geez it just flipped to warm everywhere, and now a couple rainstorms this week. Was reading that you have to go pretty far north for skiing, and find north facing mountains. Link to comment Share on other sites More sharing options...

The late week system looks juicy, just not sure how much is liquid and what's frozen. 0z NAM was quick to bring in the cold, but 6z backed way off. This threat is all about the triple point. 1 Link to comment Share on other sites More sharing options...

Hope the slopes survive the 2 during the week rainers and this one brings some white. May skiers luv this time of year, and man the resorts need March. Down here, despite some decent totals it has been another brutally short window for the resorts. Late start to year, January thaw, then after a decent cold stretch temps just been too up and down, and the snap to warmer pattern just ended the season far too early.

The NH Alpine champs are scheduled for Fri - Sun this weekend. Kids that have made it this far are the type that train year round. Athletes at this level are used to skiing in rain but cannot compete at a high level on terrain that has not frozen in a week and there is no window to reschedule. Bunch of people trying to figure this out and to say I am hanging on every model run would be an understatement. 5 1 Link to comment Share on other sites More sharing options...

Snowshoes are fun to bust out in fresh powder, but just to wear for postholing… ehhhh not really. Ice climbing had to be slim pickings this year, need those big freezes to lock it in.

RTC3-LAST CHANCE Posted March 6 Share Posted March 6 Must say really rare that the cold enough to snow switch has been turned off so early and didn’t flip back some. Really thought we would have rough patch starting around 10th or so. Long range forecasters did nice job calling it. I didn’t believe it. Our Marches have below average for the most part it seems last several years. Not this one, geez. Shut out, and many great low tracks. Total lack of help up north. 3 Link to comment Share on other sites More sharing options...
TheRex Posted March 7 Share Posted March 7 Last two runs of NAM showing snow in the area for this weekend. We are going up to Montreal for the weekend and we have seemed to be a good luck charm for Montreal getting snow while we are there.

Moderators telejunkie Posted March 8 Moderators Share Posted March 8 (edited) Just some minor timing and track discrepancies still to work out...HRRR with primary SLP almost to Lake Placid while NAM has it down near Trenton on a track towards Portland, ME. Oddly though, the realized differences between the model output isn't as wide as I would think....mainly just the southern and eastern extend of precip in that time stamp.

TheRex Posted March 8 Share Posted March 8 GFS 12Z run is pretty aggressive with snow up this way. We are going to Montreal for the weekend and it looks like we may see some heavy snow. For home it looks like we may get a lot of white rain. Quote Kuchera Snowfall The Snowfall Depth Change map looks a bit different though.

Admin MaineJay Posted March 9 Author Admin Share Posted March 9 I'm not really keen on getting too much mashed potatoes, but seems like a good chance I see a little snow. Quote SHORT TERM /SATURDAY MORNING SATURDAY NIGHT/... Saturday will feature dry weather with clouds continuing to increase. It will be cooler in most zones as southeasterly winds will be prevalent. Things change quickly Saturday night as a potent short wave trough and developing SFC low tracks northeastward toward New England. Upward vertical motion will strengthen as forcing for ascent increases. Precipitation will begin to overspread the forecast area from southwest to northeast during the evening hours, eventually covering the entire area well before dawn. The column will likely be cold enough to allow for a start as snow in most zones. Thereafter, low level warm air advection will quickly change any snow to rain across southern zones and most of the coastal plain, with the rain becoming heavy at times. It will be cold enough to support a heavy wet snow in the mountains, with some power outages possible by dawn Saturday. We have issued a winter storm watch for portions of the foothills and the mountains for the potential for a significant amount of heavy wet snow. There is an area of uncertainty in portions of the foothills southward to interior portions of the coastal plain as some guidance members show a colder solution. It wouldn`t be surprising to see some marginal areas go over to rain a little later with the strong UVVs that are expected. This could snap the temperature profile back to an isothermal look around the 0c line in the vertical. Some areas may experience this and get several inches of "mashed potatoes" before going over to rain. Hard to say exactly where that may be at this time as models and ensemble members are still waffling around a bit with respect to low track. Onshore winds will also increase markedly as the low rapidly develops. By dawn, winds may be gusting 40+ MPH with inland zones 30+ MPH. && .LONG TERM /SUNDAY THROUGH FRIDAY/... Overview: Significant storm continues Sunday morning with rain, snow, wind, coastal flooding, and land/river flooding. Broad circulation will continue precipitation in the mountains Sunday night and Monday with gusty northwest winds. Quieter weather is expected mid week with high pressure moving in. This will also contribute to a warming trend through the week. Details: Surface low pressure will be tracking into central New England Sunday morning. Positioning of the low has consolidated further inland, which adds potential for high winds over the waters and coast. In general, QPF has maintained amts, with some increases for local effects such as upslope in the NW mtns, and coastal front along the Midcoast. The 8am to 2pm time period looks to include the greatest amount of precipitation for eastern NH and central/southern ME. Dynamics are strong, and rain/snow rates will be heavy. There are additional details in the Hydrology section below, but overland flash flooding will be possible here. Towards the mountains and foothills, heavy snow will be falling with 1 inch per hour rates or greater possible at times. Combined with the low snow ratios, snow consistency will be wet. This will pose risk to adding snow load on trees. There remains uncertainty on where the rain/snow line retreats to during the day, which will be key for snow amounts in the foothills and interior. NAM continues to keep cold air dammed in the mountains, but other guidance is quicker to overrun this cool air. Kept some of the NAM temps blended in however, as CAD is typically best represented here. See Coastal Flooding section for details about this significant hazard. Winds are another aspect of the storm that has increased over the past 24 hours. Current forecasts have winds not as potent as prior storms in January, but still notable for a) interior locations seeing accumulating wet snow and b) the immediate coast. HREF range is just reaching the beginning of the storm, so have went with NBM winds and local guidance for current forecast. Would prefer to adjust towards HREF values once in range, and this should make decision for how to handle new High Wind Watch easier. System will be intensifying as it enters the CWA, and would expect winds to increase the further north up along the coast. Penetration of these strong winds inland is limited, but could still wind up with Wind Adv criteria for the ME capitol region, portions of the southern ME/NH coast, and even downslope locations on NW slopes of the mountains. Low pressure will be moving ENE overnight into Monday, and circulation remains broad. Wrap around moisture will continue precipitation across the mountains as flow becomes NW. Additional light accumulations will be possible through the day Monday. Monday will see NW winds gusting to around 40mph in the afternoon, but thankfully, due to how broad and slow the circulation is moving, there will be about 12 hours of lighter winds prior as they shift NW Sunday night. A period of quieter weather is then expected as high pressure builds in toward the middle of next week. For Monday night...low pressure will continue to deepen over the Canadian Maritimes, maintaining breezy conditions through Tuesday. Based on forecast soundings, wind gusts out of the northwest of 30 to 35 mph are possible Monday night and Tuesday, maybe reaching 40 to 45 mph from time to time. The northwest flow will promote upslope rain and snow showers in the mountains into Tuesday night with dry conditions elsewhere. Temps on Tuesday look to reach the 40s across much of the area, except 30s toward the mountains. Dry conditions persist into Wednesday with lighter winds as the high settles overhead, but the high will start to shift east of the area on Thursday as another system approaches. With the southerly flow, temperatures could reach the 50s over much of the area on Thursday before the previously mentioned system brings another chance of precipitation either later on Thursday or Friday. && 2 Link to comment Share on other sites More sharing options...
TheRex Posted March 9 Share Posted March 9 BTV's forecast discussion says forecast snow amounts could change due to a complex system. It should be fun to watch it all play out. The mountains should see wet heavy snow but then get fluffy snow on Monday. Maybe this storm will save the spring skiing season. Quote .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/... As of 347 PM EST Friday...A long duration winter storm watch has been posted for the northern Adirondacks and the central/northern Green Mountains in VT, including parts of the NEK from 00z Sun to 00z Tues where confidence is the highest for at least a 50% or greater probability of 7 or more inches of snowfall. This wl be a highly elevational dependent system, given the marginal bl temps, especially the first half, while 2nd part is lighter/fluffier snow associated with upslope component. Scattered power outages possible Sat night into Sunday for parts of northern NY and central/northern VT. It should be noted, this is a very dynamic and complex system, and snowfall fcst with marginal temps is extremely challenging and wl change. In addition, once again we are dealing with a large spread btwn the 10th and 90th percentile snow amounts acrs our cwa, which highlights the best/worse case scenarios. Latest 12z trends have been for a much stronger southern stream system ejecting from the MS River Valley into the Mid Atlantic States, which is now being captured by approaching northern stream mid/upper lvl trof acrs the Great Lakes. As trof phasing and strong 250mb jet interaction occurs, rapid cyclogenesis of sfc low pres develops acrs the Mid Atlantic into southern/central New England on Sat night into Sunday. The deepening system wl eventually become vertically stacked acrs central/northern Maine by late Sunday into Monday, advecting deep layer moisture back into our fa, supporting a prolonged upslope snow event. Timing and location of the phasing, along with placement of where the deepening of the closing 850 to 500mb cyclonic circulation occurs is very important to potential impacts acrs our cwa. Still anticipating a two part system, with first part arriving late Sat aftn into early Sunday morning, while second part is a long duration upslope event late Sunday into all day Monday. Initially temps wl be very mild on Sat, with progged 925mb to 850mb temps in the 1-3C range, but as strong dynamical forcing arrives and evaporational cooling develops as precip develops, expect thermal profiles to become deeply isothermal near 0C, with just the bl above 0C. Deep layer moisture wl be quickly advecting into our region associated with a 100-120 knot sub-tropical jet, pushing pw values in the 0.70 to 0.90 range by Sat night. Furthermore, the southeast orientation of the 850mb jet of 40 to 55 knots wl enhance moisture advection into our region, but at the same time produce favorable lift to cool the lowest levels just enough along and east of the Green Mtn Spine to support a mostly heavy wet snowfall. Similar type similar for the se upslope areas of the eastern Dacks from Essex County to Clinton County NY. Meanwhile, just the opposite occurs on the downslope side, with a bit of warming in the bl and slightly less qpf. So expect a mix of rain and snow along the western slopes and northwest dacks on Sat night into Sunday. However, if dynamics associated strong 925mb to 700mb fgen forcing cool the column enough as advertised by some meso-scaling modeling a brief 1 to 3 hr window of heavy snow is possible down to the valley floors on Sat night. These banding features and potential impacts on thermal profiles makes for an extremely challenging snowfall fcst. As just a degree or two change or a minor shift in the sfc low pres track, wl play a major influence on thermal profiles and qpf/snowfall. Forecasting snowfall amounts in this type of scenario is very difficult and expect the unexpected. Temps on Sat night hover either side of freezing, with coolest above 1500 feet in eastern/central VT and warmest CPV and western slopes. The threat for gusty winds have decreased slightly given the slightly more southern track, but still noticing a 40 to 55 knot 850mb jet and 35 to 40 knot jet at 925mb lifting from south to north acrs our region btwn 06z and 15z Sunday. However, the strongest winds seem to be colocated with the heaviest precip, resulting in less deep layer mixing. Still anticipating localized gusts in the 40 to 45 mph range for the western slopes on Sat night/Sun morning and northern dacks. First part snowfall ranges from a dusting to 2 inches SLV/CPV/Western Slopes and Lower CT River Valley with 2 to 8 inches midslopes of the northern dacks and mtns of central/northern VT, with 6 to 10 inches at summits. Meanwhile, still anticipating an overall break in areal coverage of precip on Sunday, along with associated dry slot, before upslope snow event develops late Sunday into all day Monday. The exact timing and duration of the precip break is uncertain and wl depend upon the mid/upper lvl trof evolution/track. In addition, during the brief dry slot and associated wind shifts to the south/southwest, bl temps are anticipated to warm into the mid 30s to lower 40s, especially parts of the CPV and central/eastern VT on Sunday. This should greatly improve travel issues by midday Sunday. As low pres conts to deepen and become vertically stacked winds shift to a favorable northwest upslope direction, along with moderate 925mb to 850mb caa. The closing cyclonic circulation should help to enhance a backside deformation zn of deeper layer moisture and lift, combined with enhanced low level forcing from upslope flow against the northern Dacks and central/northern Greens. This is where the Western Slopes and parts of the northern Dacks wl see the best accumulating snowfall from late Sunday into Monday. Thermal profiles show progged 850mb temps dropping to -10C to -14C with favorable moisture in the snow growth region and good llvl lift/omega. All parameters support a prolonged period of accumulating upslope snow on Sunday night into Monday. As bl temps begin to warm on Monday, expect most impacts to be confined above 1000 ft. Snowfall associated with upslope component looks to range btwn 6 and 12 inches for the Western Slopes and northern Dacks and a dusting to several inches possible for the eastern side of the CPV. Much lighter/fluffier snow is anticipated on backside with ratios in the mtns of 12/15 to 1, especially Sunday night into Monday. I realize we have a long duration watch in effect and impacts wl come in two waves, but given the complexity and potential for additional changes thought the best action attm was to issue winter storm watch where the confidence of at least 50% or greater of 7 or more inches of snowfall was the highest. I anticipate snowfall amounts wl continue to change as trends are established and system becomes better sampled by high res data, so stay tuned. 1 Link to comment Share on other sites More sharing options...
