... A clipper system will bring light accumulating snow on Sunday, followed by another chance of snow Monday into Tuesday.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Warm advection and cloud cover tonight will yield overnight low temperatures 15-20 degrees warmer than this morning. Thus lows tonight will be in the teens in most locations.
With some moisture returning to the region as well, dew points will rebound into the teens tonight as well.
SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/... A fast-moving clipper system will cross out of the Midwest into the Upper Ohio Valley on Sunday. Recent model guidance has trended stronger with this system. Modest upper support and sufficient moisture will yield 2-4 inches of snowfall across east-central Ohio, northern West Virginia, and southwest PA.
Briefly dry weather with zonal flow returns on Monday as temperatures moderate to above-freezing south of I-80. A second clipper system then quickly crosses the region Monday night into Tuesday. This system seems similar in intensity and moisture as the last system but a bit prolonged given the persistent northwest flow behind it owing to more of a Lake Enhanced up north. Given continued high SLRs and but seemingly less moisture and less jet support aloft, totals still seem to be in a 1 to 2 inch amount with some isolated amounts up to 3 inches, mainly in the higher elevations and in the northern counties.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... A few lingering snow showers will be possible in the higher terrain before dissipating. Then, building sfc high pressure and reinforced NE CONUS troughing will once again keep mainly dry and well below- normal temperature weather in the forecast for the second half of the work week. Low temperatures Wednesday night may come close or rival those of this morning for coldest of the season. The next chance for snow will come Friday with a crossing wave.
