Uptons latest afd. Dew points observed lower than forecast. 

Spoiler
National Weather Service New York NY
1026 PM EST Mon Feb 12 2024

.SYNOPSIS...
Low pressure west of the Appalachians redevelops off the
Delmarva coast Tuesday morning, and intensifies quickly as it
passes south of Long Island Tuesday morning, then heads well
out to sea Tuesday afternoon and night. High pressure will then
return from Wednesday into Thursday before an Alberta Clipper
low passes through Thursday night into Friday. A series of weak
lows may pass across during the weekend before high pressure
returns Monday.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Forecast on track and made only minor adjustments for the next
few hours. The adjustments mainly had to do with dewpoint
readings, as they have been coming in observed lower than
previous guidance.

Clouds are in the process of lowering from south to north across
the area with precip, mainly light rain knocking on the door to
the immediate south. Mid level and high end lower clouds over
the area attm will give way to pockets of light rain moving in
from the S and SW over So. NJ and the DC metro area into
Virginia. This precip will advance NE, reaching most places by
07z. P-type will likely start off rain at the coast with temps
falling thru the 30s and a weak elevated warm nose, then mix
with snow/sleet quickly within an hour or two of onset, then
mainly mostly snow towards daybreak as heavier precip starts to
arrive and the column cools, with stronger dynamic cooling to
ensue shortly thereafter. Inland the precip should be primarily
snow.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
* Winter storm to impact the area on Tuesday.

* Winter storm warnings issued for NYC metro and Long Island,
  where there is higher confidence in at least 6 inches of
  snowfall.

* Guidance continues to trend south. Forecast was originally
  based on the 12Z GFS/NAM but made some last-minute changes
  based on the 12Z ECMWF/NAM. This could put the metro area and
  Long Island more under the axis of higher QPF, with lesser
  amts north/west of NYC than originally anticipated.

Model guidance has continued to trend south, with the 18Z
ECMWF/NAM showing a tad less phasing with a northern stream
shortwave trough moving through the Great Lakes. This shift
should lead to lower snowfall amts quite a bit across the
interior, and put the axis of highest QPF either right over
the NYC metro area/Long Island or just south. At the last minute
blended the 12Z ECMWF with the 12Z GFS/NAM which were farther
north. Did not change headlines inland but lowered snowfall amts
to the 6-9 inches range across the interior, and if the
southward trend continues it is possible that northern areas may
less less than 6 inches of snowfall.

Meanwhile confidence has increased enough in higher snowfall
totals for the NYC metro and Long Island to upgrade watches to
warnings for those areas. Amts will be in the 4-7 inch range
around the NYC metro area were blyr temps will remain a little
warmer than areas to the NW and also across Long Island. Per
earlier forecasts of favorable deformation/frontogenetic
forcing near the coast and negative EPV* atop the frontogenetic
layer, there could be some slantwise instability and perhaps
some isolated thunder as the heaviest precip moves across in the
morning.

QPF of 1.00-1.25 inches expected only across the NYC metro area
and Long Island, with lesser amts of 3/4 to 1 inch to the north.

Snow ratios at the coast will likely be low at the onset, but
then increase as the snow becomes heavy (with rates at least
1-2 inches/hour) and low level winds become more northerly.

In addition, NE-N winds at the height of the storm will gust to
30-40 mph, strongest along the coast. This could further
restrict visibilities. However, with the wet nature of the
snow, blowing snow should be at a minimum and any blizzard-like
conditions should be short-lived.

NW winds on the back side of the low gradually subside Tuesday
night with clearing skies. Lows will be close to normal, in the
20s.

That is not the eye candy I came for.

2-3" does t get me up in the morning (no pun intended)

lol.  Here’s the 90th percentile accumulations.  Not sure exactly where you are, so this may be a ‘stay in bed’ graphic for you!

To Rick’s point about cold aloft, and Stretch’s about lower dew points, already sleet mixing in at 39-40 degrees! Earlier. I luv this stuff! Gonna be hard sleeping.

One word for you……

I hear ya.  I am going to have to force myself to sleep tonight.  I get migraines due to lack of sleep.  So staying up in anticipation of this storm is out of the question.  Years ago I could do it without any problems.

Magnesium, Calcium, Zinc (One supplement) has always eliminated my migraines (when coffee does not). I take a half a pill and the migraine nearly instantly subsides. That withstanding, be careful not to take too much, it will knock you out.

One of Rick’s friends at his course last week is a bourbon nut. Was telling me about a bourbon that they stick in a barrel and put in sea water. Another that is naturally smoked . 

UM... I NEED A NEW FRIEND.

Sea is Jefferson's

It's more a gimmick than anything...

Oh and I know because:

Awesome collection!  I used to work for Pernod Ricard aka Jameson, Powers, Jefferson, Malibu, Absolut, plus others. Got my hands on some nice whiskeys bartering with other suppliers too. I have to make a fancy cabinet like that, all my whiskeys are in cases still 😂

Or buy it from Costco, but a lot more expensive now than what I paid
