KEY MESSAGES

Updated at 944 PM CDT Wed May 13 2026

- A significant warming trend will take place this weekend into early next week as daytime highs will climb into the lower 90s each day.

NEAR TERM

(Tonight and Thursday) Issued at 944 PM CDT Wed May 13 2026

A cold front is making its way through the region, with a few light sprinkles and any lingering cloud cover shifting to the southeast by Midnight. A cooler, drier air mass will quickly move into the Tennessee Valley overnight as evidenced by temperatures dropping into the upper 40s to lower 50s by early Thursday morning. We will remain in northwest flow aloft, with high pressure at the surface promoting a clear, sunny day on Thursday. However, breezy northwest winds will keep highs about 8-10 degrees lower than today -- topping off in the low to mid 70s in most locations.

SHORT TERM

(Thursday night through Saturday) Issued at 944 PM CDT Wed May 13 2026

A good setup for radiational cooling Thursday night as winds decouple in a clear sky and dry air mass. As a result, low temperatures will plummet into the low to mid 40s by early Friday morning. This should be the last of the "springtime" temperatures as an upper ridge axis will build into the Tennessee Valley Friday into the weekend. This will result in a pronounced warming trend as winds veer to the south, with mostly sunny conditions both days. As a result, highs will warm into the lower 80s on Friday and the mid to upper 80s by Saturday.

LONG TERM

(Saturday night through Wednesday) Issued at 944 PM CDT Wed May 13 2026

A somewhat different upper level pattern will be in place as close out the week; with a forecast of troughing across the western North American domain, with a zonal to a slight ridging setup east. This trough west, ridging east configuration should become more firmly established as we go into the first half of next week. With troughing which had generally persisted over the eastern portion of the continent gone, warmer conditions are expected as we go into the second half of the month.

A frontal boundary remaining well to our NW should result in dry weather for the start of next week. With more sun than clouds, a southerly flow and higher heights, should allow for warmer daily high and low temperatures. It should not be as cool Saturday night, with low temperatures ranging from the upper 50s east to lower 60s west. High temperatures on Sunday should rise into the low/mid 80s, a bit warmer than normal highs of around 83 degrees. A bit milder Sunday night with lows mainly in the low/mid 60s. Also somewhat warmer Monday with highs in the mid 80s.

The above noted frontal boundary should sag closer to the area as we go into Tuesday, bringing mainly lower end shower/thunderstorm chances. Before showers commence, expect another warm day with highs in the mid 80s. Deeper moisture arriving from the Gulf region, and the frontal boundary being even closer should bring higher rain chances on Wednesday. With more clouds and higher rain chances, high temperatures should be a tad cooler, mainly in the lower 80s. Low temperatures Mon/Tue night should range in the lower 60s.

AVIATION

(00Z TAFS) Issued at 704 PM CDT Wed May 13 2026

VFR conditions will prevail through the period under a mostly clear sky. Gusty winds early this evening will weaken by Midnight to around 5 kts out of the NW.
