KEY MESSAGES

Updated at 915 PM CDT Thu Jun 4 2026

- Medium to high chances (40-70%) of showers and thunderstorms return Sunday through Thursday.

NEAR TERM

(Today) Issued at 338 AM CDT Fri Jun 5 2026

An amplified mid-level ridge (initially centered across southern portions of AL/GA) will become suppressed over the course of the near term period by a shortwave trough that will progress northeastward from the Mid-MO Valley into the eastern Great Lakes. Although this evolution will allow southwesterly flow aloft to strengthen into the 15-25 knot range (maintaining a scattered- broken coverage of cirroform clouds), the influence of the ridge will remain sufficiently strong to deflect any meaningful convection to our west, and we will retain a dry forecast for today. In the low-levels, our region will remain influenced by a weakening surface high (positioned across the southern Appalachians) as it begins to expand eastward off the southern Mid-Atlantic Coast, and this will promote light SSW winds throughout the day but with only a very minor increase in dewpoints. Following morning lows in the m50s-l60s (with some patchy fog near large bodies of water), highs this afternoon will range from the u70s-l80s atop the Cumberland Plateau to the m-u 80s in the valley.

SHORT TERM

(Friday night through Sunday) Issued at 915 PM CDT Thu Jun 4 2026

Not much change in the local weather pattern as we head into the weekend. With high pressure overhead and underneath the aformentioned upper level ridge, dry and mild conditions are forecast on Saturday. Expect afternoon highs to warm into the mid to upper 80s and overnight lows in the mid to upper 60s. By the second half of the weekend, the sfc high pressure will slowly shift to the east bringing in a more moisture rich airmass off the Gulf. As a result, diurnally driven thunderstorms return to the forecast with low to medium chances (40-60%) on Sunday afternoon.

LONG TERM

(Sunday night through Thursday) Issued at 915 PM CDT Thu Jun 4 2026

High pressure will shift east of the Tennessee Valley next week as an unsettled pattern returns. Deep southwesterly flow will really begin to advect in a warm, moist air mass on the western edge of the ridge. This is evidenced by dewpoints returning to the upper 60s to lower 70s by Sunday. Diurnally driven convection will develop each day (40-80% chance), with the greatest coverage occurring during the afternoon and evening hours. Convection on Monday and Tuesday will also be aided by a passing shortwave trough over the Mid-Mississippi and Ohio Valleys that will clip our area. Given the moist environment, all of these storms will be capable of producing locally heavy downpours. Otherwise, warm/muggy conditions which fairly typical for early June as daytime highs reach the mid to upper 80s each day.

AVIATION

(12Z TAFS) Issued at 614 AM CDT Fri Jun 5 2026

There have been no changes to previous aviation forecast reasoning. VFR conditions will exist at both terminals, featuring a sct-bkn layer of Ci and some fair-weather Cu this aftn (based arnd 4 kft). As mixing begins later this morning, calm winds will become SSW at 5-10 kts before diminishing once again this evening. Conditions should thus become conducive for the development of patchy BR/FG near large bodies of water, but at this time we will include no vsby reductions in the TAF for either airport.
