KEY MESSAGES
ACCUMULATING SNOW THROUGH TONIGHT
PERIODS OF HEAVY LAKE EFFECT SNOW THIS WEEKEND
BITTERLY COLD MONDAY AND TUESDAY WITH SNOW SHOWERS
Temperatures held steady around 22 overnight and there has been just a trace of snowfall here in my area so far. Now the real question is just how much snow will fall? Todays discussion is calling for a chance of heavy snow for this weekend. It still looks to get very cold for Monday and Tuesday. At 7:50 it is cloudy and 22 here in my yard.

The official H/L yesterday at Grand Rapids was 25/14 there was a trace of snowfall at the airport there is reportedly 1” of snow on the ground (there is just a trace here in my area) the highest wind gust was 37 MPH out of the N. For today the average H/L is 31/18 the record high of 58 was in 1949 the coldest high of 6 was in 1994 the record low of -16 was in 1972 and 1994 the warmest low of 39 was in 1933. The wettest was 0.60” in 1980 the most snowfall of 5.5” was in 1924 the most on the ground was 23” in 1979.
Some weather history for January 16th 1964 Fort Worth, TX, received 7.5 inches of snow, and Dallas reported a foot of snow. (David Ludlum) and in 1990 Heavy snow fell across the Prince Williams Sound area and the Susitna Valley of southern Alaska. Valdez was buried under 64.9 inches of snow in less than two days, including a record 47.5 inches in 24 hours. Up to 44 inches of snow was reported in the Susitna Valley. The heavy snow blocked roads, closed schools, and sank half a dozen vessels in the harbor. (Storm Data)
It's good to see. We have certainly waited long enough!
Non boring weather day today. We could see some snow showers and perhaps a snow squall.
n area of subsidence is expected late this morning through early
afternoon on the backside of the cold front, with the first mid-
level vort maxima exiting toward the southeast. Stronger CAA between
700mb-500mb will help to steepen mid-level lapse rates, meanwhile,
warming near the surface from insolation will begin to develop
modest instability. Over the past few CAM runs, 0-3km CAPE values
are progged to reach 80-100 J/kg just ahead of the cold front, and
in another area of stronger Q-vector convergence above 700mb.
Moisture will be limited, but model soundings continue to show
dendrite development with moisture being located within a favorable
DGZ. Couple that with the instability and a few sources of broad
scale lift, will be capable of generating snow showers, and some
likely to demonstrate convective behavior. A peak at simulated
reflectivity from CAM output hints at this, with banded snowfall
like features present. With winds around 30-35 kts toward the top of
the progged mixed layer, could result in snow shower bursts during
the afternoon with visibility dropping below one mile for short
periods of time. The background environment does provide some
suggestion for snow squall potential. However, the limited moisture
may prevent showers from achieving actual snow squall criteria.
Mesoanalysis will be important this afternoon to watch for changing
conditions. As for snowfall amounts, only a few tenths of an inch
are expected. With the gusty winds, getting an accurate measurement
anywhere will be very difficult. Further, daytime heating is
expected to boost surface temperatures into the upper 30s and lower
40s today, promoting melting that will also limit snow
accumulations. It is a bit odd to be talking about snow showers with
surface temperatures forecast this warm, but their occurrence is
likely given the strong forcing and instability that is expected. In
periods absent of snow shower activity, pressure gradient will be
quite strong with pressure falls extending southward toward Ozarks
region with dCVA heading toward the Interstate 44 corridor, while a
surface anticyclone attempts to develop over the High Plains. Wind
gusts above 25 MPH may continue into the evening hours. The cold
front eventually moves through the area late tonight, with drier air
eventually brining an end to snow activity
