KEY MESSAGES

Updated at 931 PM CDT Wed Apr 1 2026

- A warm, moist air mass will remain in place through the week, with highs in the upper 70s to lower 80s each day, and lows in the 60s.

- Low chances for showers and thunderstorms are forecast today and Friday.

- Much higher chances for showers and storms are forecast Saturday evening/night into early Sunday morning as a cold front pushes through the TN Valley. There is a Marginal Risk for severe storms west of I-65.

NEAR TERM

(Today) Issued at 254 AM CDT Thu Apr 2 2026

High pressure remains anchored to our east, keeping moist southerly flow in place for the TN Valley. Early morning satellite imagery shows increasing cirrus from the west with a few pockets of low stratus underneath. While we should see plenty of sunshine this morning, cloud cover is expected to expand from west to east later this afternoon. Temps will be on the warm side again today with highs in the low to mid 80s area wide. Southerly winds will be breezy at times, with gusts up to 20-25mph this afternoon. Due to the lack of better forcing, have kept PoPs capped at 20% today with the best chances east of I-65.

SHORT TERM

(Thursday night through Friday night) Issued at 931 PM CDT Wed Apr 1 2026

We anticipate more the same through the end of the work week, as high pressure to the east and a developing area of low pressure to the northwest will maintain deep southerly flow over the Tennessee Valley. The result will be a warm, humid air mass that will push daytime highs into the mid 80s and keep overnight lows in the 60s. A weak shortwave may clip northern portions of the area Friday afternoon, but our main influence will still be the ridge. As such, have kept PoPs very low (10-20%) with the NBM as subsidence should largely win out, resulting in dry (rain-free) conditions.

LONG TERM

(Saturday night through Wednesday) Issued at 931 PM CDT Wed Apr 1 2026

An upper trough is slated to pivot from the central U.S. up into Canada this weekend. Coincident with this is a surface low pressure system that looks to traverse the Great Lakes and move into Canada during this time. The cold front associated with this low is then expected to swing over the Southeast on Saturday, with high pressure building in from the west right behind it. Overall, medium to high chances of showers and storms are forecast Saturday through Saturday night. However, how much lingering precipitation there will be on Sunday will largely depend on how quickly the front moves through Saturday night/Sunday morning.

Current model guidance is fairly consistent with previous runs, indicating bulk shear values topping out around 25-30 knots Saturday through Sunday morning. Although, instability is increasing a bit from yesterday, which makes sense since our forecast highs are in the upper 70s on Saturday. CAPE values look to range around 500-1200 J/kg Saturday afternoon then decrease a bit to less than 1000 J/kg by the evening time. Therefore, the thermodynamics are sufficient for thunderstorm development. However, looking aloft, the better upper level dynamics (jet maxes) remain to our north over the Ohio Valley Saturday and into Sunday. Given this, confidence is low in the occurrence of severe weather. However, we will be monitoring the potential closely. Check back for updates as we go through the week!

Beyond Sunday afternoon, no rain is forecast through midweek. There are indications that a reinforcing cold front may move over the Tennessee Valley on Tuesday; however, there is very little moisture associated with this feature. Thus, this may bring a bit more cloud cover but mostly help maintain the cooler temperatures post FROPA, if not bring slightly cooler temperatures (especially Tuesday night). Highs are forecast to be in the 60s to around 70 degrees each day Monday through Wednesday, with lows in the 40s for most locations Monday night. Although, some spots in northeast Alabama and southern middle Tennessee may drop into the upper 30s Tuesday night! It may be a good idea to keep those jackets handy and not pack them away for the season, since the cooler weather hasn't left us just yet!

AVIATION

(12Z TAFS) Issued at 559 AM CDT Thu Apr 2 2026

VFR conditions will persist through the TAF period at both terminals as high clouds increase from west to east. Southerly winds will become breezy later today, gusting to 20-25kts at times before. Winds should begin to lessen after 00z.
