11/24 – Rob Knight’s “Thanksgiving Eve” Morning Forecast

Rapidly increasing temperatures today will jump by several degrees along with increasing cloudiness. Low level moisture will also begin to return as high-pressure continues east, a splitting trough will be racing east across the Rockies. The southern portion of this disturbance will hang up south of Arizona. The remainder will keep on trucking east through the midsection of the country Thursday, bringing a cold front towards the area. Precip chances Thursday are really just for the end of the daylight hours as the front will just be reaching northern LA and MS in the afternoon hours. Activity will mostly be post frontal within a region of little to no instability. As such, I’m only expecting showers and weak ones at that. High pressure will build in behind the front on Friday. The combo of that and lingering clouds will yield high temperatures several degrees below normal.

Friday into the weekend, the cooler trend will continue as cold air advection persists and temps struggle to reach mid-60s. An area of low-pressure will develop along the NW’tern Gulf Sunday, which may bring some moisture back into the forecast. With this, precip chances on Sunday gradually increase with around 20-30% in the afternoon before quickly falling again. With really no instability to work with, likely only some light rain showers over the area at most. Beyond that a very quiet extended period as high pressure dominates the forecast through Tuesday.
