(Sunday night through next Friday)
Issued at 325 AM CST SAT DEC 7 2024

Key Messages: - Heavy rainfall from 1 to 3 inches will be possible across the forecast area from Monday through early Wednesday morning with isolated amounts up to 4 inches possible across portions of Southeast Central Alabama.
- A widespread freeze is forecast next Thursday and Friday morning.

Sunday Night through Monday Night.

An upper low will open into a shortwave trough as it moves east over the Southern and Central Great Plains while a few mid-level disturbances move over the area from the southwest. Surface high pressure will move further southeast, becoming centered across the Southwest Atlantic while a warm front develops from lower pressure across the Central Plains, extending southeast toward the Mississippi Gulf Coast.

Expect continued increasing clouds Sunday night into Monday with rain showers becoming likely across the northwest Sunday night and expanding southeast during the day Monday. Lows Monday morning will range from the mid 50s far north and northeast to near 50 far south and southwest. Highs Monday will range from the lower 60s in the higher elevations far east to around 70 far south and southwest.

Tuesday.

The first shortwave trough will rapidly move east-northeast toward the Mid-Atlantic Region by Monday night while another shortwave impulse becomes better defined Monday evening over the Lower Mississippi River Valley Region and approaches the area from the southwest. Surface low pressure will become better organized across South-Central Oklahoma with a diffuse warm front remaining to our southwest with surface high pressure remaining to our east across the Southwest Atlantic Basin.

Cloudy skies with an increase in showers is forecast over much of the area during the early morning hours on Tuesday, followed by decreasing chances northwest later in the morning hours. Rain chances will continue to decrease across the northwest during the afternoon hours, especially near and northwest of Interstate 59 while the best chances for rain will continue southeast of Interstate 85 through the afternoon. Thunder potential has decreased and would be confined to the far southern tier of counties during this time frame. Lows Tuesday morning will be in the 59s areawide with highs from the lower 60s northwest and across the higher elevations far east to readings in the lower 70s generally near and southeast of the Interstate 85 corridor.

Wednesday through Friday.

A sharp positively-tilted longwave trough will swing east over the Lower and Middle Mississippi River Valley Region early Wednesday then quickly lit northeast toward the Atlantic Seaboard toward evening. A northwest flow pattern will be left in its wake into Thursday. Available global model guidance maintains a slight northwest to a zonal flow pattern over the area into Thursday while one solution brings a shortwave southeast over the area Thursday night, will discount that depiction as an outlier for now. Shortwave ridging builds over the area from the west on Friday while two solutions tries to develop a trough over the Central Plains later in the day on Friday. An end to the shower activity will come as a cold front sweeps southeast across the area early on Wednesday. Another reinforcing cold front will move into the area early on Thursday followed by surface high pressure migrating southeast from the Northern Plains into the region later in the day. Surface high pressure will move northeast and become centered across the Mid Atlantic Region early on Friday.

Skies will become partly cloudy northwest while remaining mostly cloudy southeast as some lingering showers will remain possible generally near and southeast of the Interstate 59 corridor Wednesday morning, followed by a return to dry conditions areawide with continued gradual clearing skies from the west and northwest through the rest of the day on Wednesday. Dry conditions will accompany Wednesday morning lows across the northwest near freezing while readings will be in the lower 40s southeast. High temperatures will range from the mid 40s far north and across the higher elevations east to the lower 50s across the southern third of the area.

Fair skies with dry conditions are forecast Thursday and Friday with a widespread freeze forecast both mornings with lows in the 20s areawide. High temperatures will range from the upper 40s northeast to the low 50s far south Thursday and will moderate into the 50s areawide on Friday.
