SPC MD 63 MD 0063 CONCERNING SNOW SQUALL FOR PARTS OF NORTHERN
AND CENTRAL PA
Mesoscale Discussion 0063 NWS Storm Prediction Center Norman OK 0737
PM CST Mon Jan 10 2022
Areas affected...parts of northern and central PA
Concerning...Snow Squall
Valid 110137Z - 110400Z
SUMMARY...A snow squall will continue spreading southeastward across
parts of northern and central PA over the next few hours, with sudden
visibility reductions of a half mile or less.
DISCUSSION...Radar imagery from CCX/BGM shows an east-west oriented
snow squall moving southeastward across parts of northern PA, where
sudden visibility reductions of a half mile or less have been noted.
Ahead of the snow squall, RAP forecast soundings depict a deeply
saturated and unstable boundary layer, where VWPs show 30-35 knots of
0-2 km flow. The latest high-resolution model guidance suggests that
this snow squall may persist for another few hours as it advances
southeastward across parts of northern and central PA, where sudden
visibility reductions will be possible. A lack of stronger low-level
convergence with southward extent should eventually lead to the demise
of the snow squall.

...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
A few thunderstorms are expected across parts of central and south
Florida through tonight.
...DISCUSSION...
The latest water vapor imagery shows northwest mid-level flow from the
central and northern Plains to the Appalachians with an upper-level
trough near the eastern Seaboard. At the surface, a cold front is
located in south Florida. A moist airmass is present along and to the
south of the front, where the RAP is analyzing MLCAPE in the 1000 to
1200 J/kg range. Thunderstorms are ongoing within the unstable airmass
along the east coast of Florida near West Palm Beach. Other isolated
storms are ongoing in far south Florida. A chance of storms should
persist in south Florida this evening. But the advancing cold front
will result in lessening instability, making thunderstorm development
more isolated with time.
