Technical Forecast Discussion
Short term (Wednesday 1/9 through Saturday 1/12)
Upper level troughing looks to leave the area sometime Sunday. Moisture will still be in the region for the earlier part of Wednesday as the trough brings it down from the low pressure system that now hangs off the northeast coast. An absence of disturbance will bring back mid and upper level zonal flow that looks to persist through most of the forecast period. Clouds will begin to increase Saturday as upper level flow turns into a trough that helps moves a low pressure system from the Rockies into the region. Vertical temperature and moisture profile are indicative of substantial snowfall.
Long term (Sunday 1/13 through Tuesday 1/15)
Upper level flow is rather disorganized on Sunday. Troughing is visible well to the north, with zonal flow right below the region. At the mid levels there is a weak shortwave trough visible over the region. This is due to the low pressure system tat moves through on Saturday. This and available moisture will allow for isolated snow showers and cloud cover to continue through late Sunday. Disorganized ridiging arrives on Monday that will promote some high pressure in and around the region. A narrow band of moisture associated with troughing up north will be responsible for some clouds staying in the region as the forecast period progresses. A developing system will likely head into our egion from the Plains on Wednesday.
