Technical Forecast Discussion

Short term (Wednesday 1/30 through Saturday 2/2)

The cold front will be well pass the region on Wednesday as a scenario for a cold wave begins. Cold, dry air is pushed into the region due to the troughing allow cold air to move southward. Moisture will begin to be removed late Wednesday as dry air from the cold front pushes it out. There is a likelihood that lows will be below zero late Wednesday as the center of the cold mass nears the region. Upper level ridging begins to move into the region late Thursday as cold air remains. Ridging will move in Thursday as dry is is advected through the region. A developing warm front on the eastern edge of the upper level ridge will influence precipitation Thursday night and Friday. This front will push moisture and cold air into the region resulting in snow showers and cloud development Thursday night through Friday evening. Large amounts of WAA are promoted Saturday as the ridge moves over the region resulting in cloud clearing and temperatures rising to a much more tolerable range in the 40s and 30s.

Long range (Sunday 2/3 through Tuesday 2/5)

WAA continues Sunday as the warm front moves northward into southern Canada as the region sits in the middle of upper level ridging as highs will be in the upper 50s. Clouds will increase Sunday night as moisture in the Gulf of Mexico is dragged upstream into the Mid-Atlantic. A shortwave over the Plains looks to strengthen a low pressure system that originates in Western Canada. The shortwave will force the cold frontal boundary into the region sometime Monday. Bands of rain showers are likely through Monday. A small upper level ridge and dry air moves in on Tuesday as precipitation clears.
