... Upper low departs and snow gradually ends. High pressure takes control late week, followed by another low pressure system next weekend.
NEAR TERM /THROUGH THURSDAY/... As of 555 PM Wednesday...
Updated package to cancel winter weather advisory for the lowlands including southeast OH. Radar and sfc obs indicate that the wet snowfall has became light and not sticking on the ground.
Winter weather advisory remains in effect for the western slopes and a Winter storm warning remains in effect for the higher elevations. Rest of forecast remains on track.
As of 215 PM Wednesday...
Temperatures across the lowlands are largely at or just above freezing, so accumulating snow from anything falling after the early morning hours have been difficult to come by in this particular area. In the mountains, however, snow continues to accumulate, and have this continuing well into the evening. HRRR and RAP are showing a gradual dissipation of coverage and intensity going forward as the upper level closed low accelerates up the Atlantic Coast.
High pressure moves in later tonight, scouring out the mountain low level moisture, but hold low end POPs until the thermal trough shows signs of degradation. 850mb temperatures will not recover very much during the day on Thursday. Skies clear southwest to northeast.
SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... As of 320 PM Wednesday...
The period begins dry and cold under the influence of broad troughing across the eastern CONUS and surface high pressure. The resulting temperatures will be around 10 degrees below normal for mid-late March. Ridging in the central Plains is interrupted by a rather wound-up short wave aloft ejecting out of the Rockies with lee-cyclogenesis occurring on the surface by Friday afternoon. As the low tracks across toward our area, it will intensify as it enters the right entrance region of a Great Lakes jet aloft.
Precipitation along the system's warm front will enter the Tug Fork/Big Sandy basin by Saturday morning. Depending on the timing of onset relative to solar insulation, snow will fall upon precipitation onset with a brief period of sleet and freezing rain before a switch to all-rain with warm air advection Saturday. Models agree that the center of low pressure will pass to the south of us, limiting convective potential and thus heavy rainfall potential with PWAT barely reaching 0.75" in the Tristate area. As the system exits and cold air advection kicks in with trough passage, temperatures will again drop and switch rain back to a wintry mix/snow overnight.
Snowfall accumulations look to be up to 2 inches in the lowlands with widespread amounts generally under an inch. The mountains will likely see more as 850 temperatures begin to drop and support accumulation, especially as the system exits Saturday night into early Sunday, on the order of 2-4" and locally up to 6" total. A light coating of ice is also possible upon onset in the coal fields and sheltered valleys with a warm nose aloft.
LONG TERM /SUNDAY THROUGH WEDNESDAY/... As of 350 PM Wednesday...
High pressure and ridging returns Sunday night through early Tuesday with southwest flow finally bringing some much-deserved warmer temperatures into the region. Look for Tuesday high temperatures near 60 in the lowlands with deep southerly flow and strong warm air advection. Positively tilted troughing over the central Plains approaches mid-week, placing us at the end of the fire house yet again - looking a another wet pattern to set up with PoPs rising in the Mid-Ohio Valley Tuesday into Wednesday. Did not deviate much from a consensus blend through the long term.
