... A wintry mix of precipitation is expected today with low pressure. The mix should change to snow tonight before gradually tapering off Wednesday.
NEAR TERM /UNTIL 6 PM THIS EVENING/... Added a Winter Weather Advisory for the Laurel Highlands through early afternoon. Temperatures on the ridge tops are near freezing, and should fall some as evaporative cooling occurs when precip begins. Enough warm air aloft exists for precip to fall as rain, and freeze on surfaces. Previous discussion below.
A wintry mix of precip should overspread the region mainly S of I 80 today as low pressure tracks across the TN and OH Valley regions. Warm advection ahead of the low should result in mainly rain or a rain snow mix S of I 70 outside of the higher terrain. Rain and snow is expected N of I 70, along with a brief, slight chance for freezing rain. Little if any accumulation of ice or snow is expected with marginal temperatures and the high March sun angle, though the colder Laurel Highlands could see an inch or two of snow. Some model progs appear to be too high with high QPF/snowfall due to overdone strong omega bullseyes in warm advection.
The higher terrain of WV and MD should see snow and freezing rain transition to mainly snow today. Will maintain the Winter Storm Warning for the expected snow and ice accumulations, with temperatures more favorable for accumulation with cold E upslope flow.
Precip should decrease in coverage this afternoon as the best upper support and lift exits.
SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... A second low is progged to dig across the OH/TN Valleys tonight and part of Wednesday. Cold advection in the wake of the initial Tuesday low should result in all snow across the region. Maintained the Winter Weather Advisory and the Winter Storm Warning with accumulation expected as temperatures drop below freezing at night. Expecting generally 2-4 inches total for areas S of I 80, with amounts from 6-12 inches in the higher terrain where the Winter Storm Warning is in effect.
The snow should taper off from N-S Wednesday as lift/upper support shifts off the E Coast with a developing coastal low. Dry weather returns with shortwave ridging Wednesday night and Thursday. Below average temperatures are expected to continue.
LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... Surface ridging should maintain dry weather until a srn stream low returns rain and snow chances S of I 80 Sat thru early Sun night. Limited POPs to chance with a significant model shift swd with the low in recent solutions. An Ern CONUS ridge should return dry weather later Sun and part of Mon before a Midwest trough returns low precip chances late Mon.
