... Some light snow showers will linger today in the wake of a cold front. A dry and seasonably cold Tuesday is expected before mixed precipitation and rain return for Wednesday.
NEAR TERM /UNTIL 6 PM THIS EVENING/... 1045 AM Update: Light snow continue across much of the CWA in moist NW flow and in the vicinity of a low level trough axis, or source of low level convergence. The 12z PBZ sounding showed boundary layer moisture extending up to about -11C. This moisture likely extends a bit higher now as hydrometeor type has transitioned over to well-defined dendrites.
The snow showers will continue across much of the area over the next few hours given sufficient moisture in the dendritic snow growth zone (DGZ) and some weak lift. Accumulations will be light with less than a half inch expected in most areas. The exceptions are the ridges and areas north of I-80, where around an inch may be seen.
Dry air will begin to enter the DGZ by mid-afternoon, which should snuff further snow shower development. Temperatures will remain steady most of the day, ranging from the mid 20s in the north to mid 30s in the lower elevations south of the Mason- Dixon line.
SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/... High pressure will suppress snow showers through Tuesday. Expect seasonable cold to continue under zonal flow aloft.
A wintry mix, including possible freezing rain is again anticipated for Wednesday as a warm front surges across the region in extension fm Midwest low pres. A couple problems are emerging in this strong warm advection regime including a period of freezing rain for most of the area, which may linger through the day in the dynamic cooling areas of the eastern ridges and I 80 corridor.
The initial warm surge may also generate some accumulating snow, potential for which should eventually be hampered by warm advection aloft/degradation of dendritic growth. Nevertheless, a Winter Storm Watch was issued in conjunction with neighboring WFOs for accumulating snow with the ice. This for Garrett, MD and Ern Tucker WV. For other zones, a Hazardous Weather Outlook mention was continued.
This system is also projected to generate decent rainfall with an inch, to inch and a half progged over the Upper Mon and Cheat River basins.
LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... Development of a fairly deep Wrn CONUS trough is still projected this week with persistent SW flow over the Upr OH Region. Expect temperature at, or above the seasonal averages and continued shortwave-dependent precip chcs.
