MD 0186 CONCERNING WINTER MIXED PRECIPITATION FOR PARTS OF PA...FAR NORTHEASTERN WV...FAR NORTHERN VA...MD...AND NORTHERN/WESTERN NJ
Mesoscale Discussion 0186
NWS Storm Prediction Center Norman OK
0813 PM CST Thu Feb 24 2022
Areas affected...Parts of PA...far northeastern WV...far northern
VA...MD...and northern/western NJ
Concerning...Winter mixed precipitation
Valid 250213Z - 250715Z
SUMMARY...A mix of freezing rain and sleet will develop
northeastward into the overnight hours.
DISCUSSION...Latest water vapor imagery depicts a strong shortwave
trough and accompanying midlevel speed maximum advancing eastward
across parts of the Middle MS Valley. Ahead of the shortwave trough,
surface observations show pressure falls being maximized in the OH
vicinity, where a low pressure system will continue to develop over
the next several hours. As the cyclone deepens, increasing southerly
flow and related warm air advection will overspread the Central
Appalachians and Mid-Atlantic states, resulting in a gradual
increase in winter precipitation in the 03Z-08Z time frame.
Across the southern and central portion of the discussion area, RAP
forecast soundings show 850-mb temperatures increasing to 3-5 C atop
a shallow subfreezing layer, which will favor complete melting of
descending hydrometeors prior to refreezing near the surface. This
will result in primarily freezing rain, with rates as high as 0.05
in/hour owing to the strengthening forcing for ascent and deep-layer
moistening. With northward extent, observations and forecast
soundings show a deeper low-level subfreezing layer, with 850-mb
temperatures near 1-3 C, indicative of partial melting of
hydrometeors and the potential for sleet and freezing rain.
Farther north across northern PA, moderate snow is likely to develop
where deeper cold air is in place, with an eventual increase in
snowfall rates expanding northward into NY during the early morning
hours.

Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0642 PM CST Thu Feb 24 2022
Valid 250100Z - 251200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are possible tonight from Louisiana northward into the
Mid South and Ohio Valley regions.
Scattered shallow convection has developed along a cold front across
central Mississippi. Expect convection to remain shallow into the
overnight period and eventually be undercut by the cold front.
Therefore, the severe weather threat remains minimal.
Isolated thunderstorms will remain possible in a region of weak
elevated instability through the Tennessee and Ohio Valley regions.
