February 23, 2010 - Why So Glum?

Clouds are in the forecast through the weekend with minimal precipitation - so why all the clouds?

I'm sure everyone is happy about the lack of snow over the past two weeks, but the new complaint is, WHERE IS ALL THE SUNSHINE?

Several disturbances will be moving through the region before low pressure stalls over New England this weekend. The low pressure system that brought us light rain Monday continues to meander off the east coast Tuesday afternoon. Northwesterly winds will partially dry the Valley and start upslope rain/snow showers in the the higher elevations.

A potent upper level disturbance will move across the Mid-Atlantic region Tuesday night, enhancing the upslope flow on the western slopes of the mountainside. The disturbance will also reinforce the cold air in the region and bring the clouds back in. 

Another area of low pressure in the atmosphere will move through the area Wednesday and combine with moisture moving up the Carolina coast. This may bring a light rain/snow mix to the southern Valley but the majority of the precipitation will stay to the east. A coastal low forms off the Carolina coast Wednesday evening and begins to move north. The shield of precipitation will once again stay to our east, but the clouds will hang over the Valley with a few rain/snow showers possible. Western slopes of the higher elevations will continue to see upslope snow as wrap around northwesterly winds bank up on the Appalachians.

Low pressure will move along the coast and into New England, delivering inches, and maybe even feet of snow to New England and portions of the Mid-Atlantic. Once entering New England, low pressure stalls and continues to filter moisture into the region. Northwesterly winds will persist through the weekend, continuing the upslope snow in the higher elevations.

We'll start to see a few more peeks of sunshine by the time we get to next Monday and Tuesday.
