KEY MESSAGES

Updated at 1040 PM CDT Wed May 14 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.

- Showers and thunderstorm will return to the forecast towards the middle of next week, but coverage is very uncertain.

NEAR TERM

(Rest of tonight and Friday) Issued at 1040 PM CDT Thu May 14 2026

An upper passing upper level disturbance has deepened into a closed low over the NY/PA border. This has induced another round of troughing over the eastern North American domain. This however appears will be the last major troughing over the eastern portion of the continent for the foreseeable future. This upper system should continue heading eastward in the prevailing westerlies, exiting the Newfoundland coast by Saturday evening. While the above occurs, an upper level system over the northern Gulf of Alaska will head to the ESE, and eventually produce synoptic scale troughing over the western CONUS, with strong ridging forming over the eastern areas. This will result in a noticeable warming trend for the upcoming weekend and for a good part of next week.

For tonight, broad high pressure presently over the OH/TN Valleys will head eastward. With the above noted troughing in place, one more chilly night is forecast, with lows dropping into the 40s (lower 40s east to mid 40s west). Given clear skies, light winds, and generally dry air filtering in, we could see lows near 40 in the coldest spots before daybreak. As the surface high near the eastern seaboard tomorrow morning, light winds will become southerly 5-10 mph. This and more sun than clouds should help high temperatures climb into the upper 70s to lower 80s, close to seasonable norms.

SHORT TERM

(Friday night through Sunday) Issued at 1040 PM CDT Thu May 14 2026

As the surface high moves further eastward, off of the Mid Atlantic coast, a southerly flow will help producing a warming trend. As such, not as cool Friday night with lows from the the lower 50s east to lower 60s west. Moisture from the Gulf, as well as blow off clouds from convection to our west will result in more clouds than sun on Saturday. Even so, warmer air and higher heights will help bring high temperatures to and just above seasonable norms for this time of year, into the low/mid 80s. Normal high/low temperatures for Saturday are around 83 degrees for reference. Even milder Saturday night with lows in the mid 50s to lower 60s. And warmer on Sunday with highs rising into mid and upper 80s. The deterministic models, as well as the blends are keeping the showers out of the area, so am maintaining a dry forecast through Sunday.

LONG TERM

(Sunday night through Thursday) Issued at 1040 PM CDT Thu May 14 2026

An upper-level ridge of high pressure will shift east of the area early next week, with deep southerly flow increasing across the Tennessee Valley. This will increase/reinforce a very warm, moist air mass across the region as evidenced by high temperatures climbing into the upper 80s to lower 90s and dewpoints reaching the mid to upper 60s. The ridge will begin to break down Monday night into Tuesday as a deepening upper trough over the Rockies swings onto the Great Plains. This will send a couple of shortwaves through the Mid South and Ohio/Tennessee Valleys on Tuesday, Wednesday, and Thursday. As a result, low to medium (20-40%) chances for showers and a few thunderstorms will return to the forecast Tuesday afternoon and evening. A sharper trough may send a weak front through the area on Wednesday and Thursday, bringing medium (40-60%) chances of showers and thunderstorms during the afternoon and evening hours, before finally shifting east of the area late Thursday night.
