11/28 – Rob Knight’s “Happy Thanksgiving” Morning Forecast

Cooler and dry weather is on tap for Thanksgiving Day with mostly clear to partly cloudy skies prevailing. Temperatures will begin to rebound on Friday as high-pressure aloft builds over the eastern U.S. in advance of a storm system over the western U.S.

As the large upper low-pressure will move into the central part of the country on Saturday, southerly flow in advance of this system will advect a warmer and more moist airmass back into the region. T-storms will be possible by late afternoon across the northwestern sections of the forecast area with shower and thunderstorm threat then spreading east across the forecast area Saturday night into early Sunday. The main dynamics associated with this system will pass well to our north and instability will be modest, but there may be enough shear for a few strong to possibly severe storms from very late Saturday through Saturday night…to the west of our area. The severe threat, however, will likely gradually diminish as Saturday night progresses as instability wanes.

Thereafter, cooler and dry weather will again be observed as northwest flow aloft prevails into the middle of next week. Another chance for rain will be in the offing for the end of next week as a weakening shortwave trough moves across the lower Mississippi Valley and Gulf Coast states.
