KEY MESSAGES

Updated at 954 PM CDT Sun Apr 12 2026

- Low RH values and gusty winds may result in elevated fire weather conditions Tuesday through Wednesday.

- There is a low chance of thunderstorms on Thursday.

NEAR TERM

(Today) Issued at 353 AM CDT Mon Apr 13 2026

High clouds continue to stream across the Tennessee Valley early this morning on an otherwise tranquil start to the day. Southwest winds are continuing to maintain a very mild air mass as evidenced by 08z temperatures in the mid to upper 60s. This southwest flow will gradually help to increase Gulf moisture into the area as evidenced by dewpoints creeping into the low to mid 50s. Combined with highs in the low to mid 80s, this will keep Min RH values between 35-45 percent and above critical levels. Additionally, winds will also be lighter and generally 10 MPH or less which will mitigate the threat for elevated fire weather conditions today. Still, given the very dry fuels, please continue to exercise caution and avoid uncontained outdoor open flames. Additionally, some very low chances (10-20%) for a few light showers have also been added to the forecast through the remainder of the day due to the increased moisture and weak lift provided from a shortwave to the west.

SHORT TERM

(Monday night through Wednesday) Issued at 954 PM CDT Sun Apr 12 2026

The aforementioned upper high will meander back westward during the short term period as the H5 ridge becomes better amplified and the unseasonably warm and dry airmass continues. The main concern during the short term period will be the risk for Red Flag conditions Tuesday and Wednesday. Right now, forecast winds are below critical thresholds but min RH values dip near or below 30% each afternoon. If guidance is underestimating low level gradient flow much like with today's forecast, this could push us back into Red Flag criteria on one or both days. Trends will be monitored carefully, and residents need to continue to take measures to avoid sparking open flames.

LONG TERM

(Wednesday night through Sunday) Issued at 954 PM CDT Sun Apr 12 2026

Heading into the latter half of the week, an upper wave will run into the ridge that has been hanging onto the Southeast and Mid-Atlantic. As the wave lifts into the Upper Midwest Thursday afternoon, another weaker wave seems to develop in the Lower MS Valley. This southern wave will bring a low chance (20-40%) of showers and some thunderstorms on Thursday. We are in desperate need of rainfall, so will take what little amount we can get out of Thursday. Those rainfall chances will be short lived as a ridge builds back into the region on Friday. This will push daytime highs to even more unseasonably warm values than what we have been experiencing this Spring. Some of us could see our first 90 degree reading of the year on Friday afternoon, 15+ degrees above normal! Now this may not be considered hot for Alabama, however it is for mid April, so be sure to be heat smart. Take it slow, seek shade and remain hydrated. Welcomed rain chances return this weekend, sorry it's over the weekend, as a trough digs through the Plains and back up into the Midwest and drags a cold front into the Southeast. Unseasonably warm temps in the upper 80s will linger into Saturday but values will drop on Sunday after the frontal passage. Look for highs that are much cooler, yet seasonable, in the mid to upper 70s.

AVIATION

(06Z TAFS) Issued at 1226 AM CDT Mon Apr 13 2026

VFR conditions will prevail through the period with SCT/BKN decks of cirrus clouds passing overhead. Winds may become gusty out of the SSW this afternoon between 10-20 kts, before weakening after sunset.
