.DISCUSSION...
(Tonight through next Thursday)
Issued at 1003 PM CST THU NOV 27 2025

Cold advection will continue tonight as an area of high pressure
moves in from the northwest. As the pressure gradient relaxes,
radiational cooling will become more of a factor, and temperatures
should bottom out in the mid 20s to around 30 at daybreak on
Friday. Cool northerly flow will continue into Friday afternoon,
limiting daytime heating, and afternoon high temperatures may be a
degree or two lower compared to Thanksgiving Day.

High pressure will move to the east on Saturday ahead of an
approaching shortwave trough, resulting in the development of
southerly low-level flow and warmer temperatures. Eventually
moisture recovery will become sufficient to maintain a narrow
corridor of showers as a cold front moves across the state late
Saturday night and Sunday.

Between shortwaves, Sunday night through part of Monday should
remain dry. As the next shortwave swings into the Southern Plains
on Monday night, isentropic lift will develop in the post-frontal
environment. A cold rain will become widespread Monday afternoon
through Tuesday morning as a surface low skirts the Gulf coast
before moving up the Atlantic coastline. Behind this system, we
can expect a return to cooler and drier conditions for Tuesday
afternoon through Thursday.
