Technical Forecast Discussion
Short term (Wednesday 11/21 through Saturday 11/24)
Ridging approaches the region on tonight as a dry cold front will move through for the later half of the day. Moisture will be aloft, but upper level conditions are not favorable for precipitation and likely only generate cloud cover for from the afternoon to the evening on Wednesday. With the ridge still making its way into the region, it will promote high pressure for the area on Thanksgiving Day as cloud cover finally clears across the state. As Friday approaches, high pressure will stay in the region until a shortwave trough moves in during the late evening. This will produce rain showers into Friday night into Saturday as more upper level disturbances are present for Saturday.
Long term (Sunday 11/25 through Tuesday 11/27)
Ridging present on Sunday will leave on the earlier part of the day 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. 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.
