Rickrd Posted February 17 Share Posted February 17 (edited) 10:20 pm. Nazareth, PA. light snow. 30f probably about 20 mins of virga from radar shot. let the game begin. Good luck all! Edited February 17 by Rickrd Link to comment Share on other sites More sharing options...
JDClapper Posted February 17 Share Posted February 17 That band just keeps drifting north, but is losing some umph.. almost appears to be through and to the north of the Sunbury area soon. Yikes. 😮 Link to comment Share on other sites More sharing options...

Jim Posted February 17 Share Posted February 17 12 miles NNW of center city Philadelphia. Either nothing falling from the sky or it's not making it to the ground. Temperature 35.8 Link to comment Share on other sites More sharing options...
Lazman Posted February 17 Share Posted February 17 (edited) Light Snowfall began here about 15 minutes ago. Kinda medium sized flakes. Let's see what happens.. Edited February 17 by Lazman Link to comment Share on other sites More sharing options...

JDClapper Posted February 17 Share Posted February 17 Might be starting to see a 2nd band emerge .. creating subsidence between the north band and it.. and also maybe to the south of it, which HRRR/RAP have really get accums low (bust) in SEPA all PM. 😮 1 Link to comment Share on other sites More sharing options...

Burr Posted February 17 Share Posted February 17 Was trying to stay up for the first flakes, but I’m going to catch some zzzs. Good luck to us all! The second band pointing in my general direction. 1 Link to comment Share on other sites More sharing options...
Wtkidz Posted February 17 Share Posted February 17 From LWX AFD NEAR TERM /THROUGH TONIGHT/... Snow has begun across far western areas based on sfc obs at 2G4. In addition, the snowfall rate satellite produdct from a MetOp-C pass at 0155Z indicated that snow was falling aloft across northern MD and VA west of US-29 at that time, but was still not reaching the ground yet per sfc obs. The wetbulb zero height on the 00Z IAD sounding was only 740 feet indicating the p-type should be snow here once precip makes it to the ground. While the fcst remains generally on track, there are some p-type issues across the southern half and southeastern portions of the CWA where sfc obs and model fields show a pressure trough/wind shift from NE to SE. This sfc trough/wind shift line currently lies along US-29. While the winds should shift overnight around as low pressure passes to the south, there air is still mild in those areas with temps in the mid to upper 40s. Low level temps and thicknesses in those areas support more rain than snow especially across southern MD, Charlottesville, and Fredericksburg. Believe snow totals in those areas are more than likely to be on the lower end of the range or even less with more rain than snow. As previous fcstr mentioned, there could be multiple snow bands that develop across the region overnight. Latest model output continue to suggest this with one band setting up across southern Pennsylvania and another one setting up across northern VA into central MD with a minima in QPF across northern MD east of Cumberland and across the eastern WV panhandle. The snow should end no later than 12Z Saturday everywhere. 1 Link to comment Share on other sites More sharing options...

Undertakerson2.0 Posted February 17 Share Posted February 17 (edited) Mesoscale Discussion 0149 NWS Storm Prediction Center Norman OK 0933 PM CST Fri Feb 16 2024 Areas affected...Northeast West Virginia to western New Jersey Concerning...Heavy snow Valid 170333Z - 170730Z SUMMARY...A swath of moderate to heavy snowfall will continue to spread east across parts of the Mid-Atlantic over the next several hours. DISCUSSION...A swath of moderate snowfall continues to spread east from the upper OH River Valley region into the Mid-Atlantic based on recent regional reflectivity composites. Transient organized snow bands continue to be observed within this broader zone, resulting in visibility reductions from 1/2 to 1/4 mile and steady snowfall accumulations based on recent snow reports from the region. Favorable phasing of synoptic ascent ahead of the approaching shortwave trough and strong isentropic and frontogenetic lift within the 925-700 mb layer, which has been driving this activity so far, is expected to persist as the system pushes towards the East Coast over the next several hours. Latest forecast guidance depicts reasonably high probability in snowfall rates between 1-2 inch/hour across portions of the Mid-Atlantic region (and possibly as far east as the NJ coast) through 08 UTC. Based on observed trends, this depiction seems fairly reasonable. One caveat is a lingering warm/dry layer below 850 mb sampled by regional 00 UTC soundings and noted in surface observations across northern MD, southeast PA, and into western NJ, which may limit snowfall rates in the near term. However, a combination of evaporative cooling and persistent mesoscale ascent along the warm frontal zone should support adequate low-level saturation/cooling to allow for moderate to heavy snowfall in the coming hours. ..Moore.. 02/17/2024 Edited February 17 by Undertakerson2.0 1 Link to comment Share on other sites More sharing options...
