Technical Forecast Discussion

Short term (Sunday 11/25 through Tuesday 11/27)

Ridging present earlier today will leave as an upper level trough approaches. This will help propagate a low pressure system into our region Sunday night into Monday. The trough gains negative tilt indicating a strengthening of the low. Strong vorticity is present within the trough late Sunday which could translate to heavy periods of precipitation. Temperatures are around the high 30s Sunday night and in the low 40s on Monday, so precipitation is likely to be only in the form of rain. Precipitation will turn to snow in the late afternoon as temperatures fall quickly. Embedded upper level disturbances accompany an upper level low on Tuesday, but dry air following the cold front from Monday will likely stop any precipitation for Tuesday, but cloud cover will remain.

Long term (Wednesday 11/28 through Saturday 12/1)

Upper level ridging will be in the region around the afternoon on Wednesday which will result in sky clearing for the latter half of Wednesday. Moisture in the upper levels will slowly move east on Wednesday as another band of moisture at 700mb is present. Upper level ridging seems to weaken heading into Thursday. This lines up with when another band of moisture moves into the region. High pressure that is present in the Appalachians will halt cloud production from this source of moisture and keep Thursday relatively clear. A small chance of showers exist Thursday night through Friday due to the presence of moisture, but models are showing little to know forcing that can overcome the high pressure. Another chance for showers is possible late Friday as a warm front associated with an incoming low pressure system moves in. As Saturday approaches, the region will enter the warm sector of the system and be in a clear and warm state for the rest of the day.
