KEY MESSAGES

Updated at 1010 AM CDT SUN Mar 29 2026

- Dry conditions are expected through the middle of the new workweek.

- Showers and thunderstorm chances increase starting Tuesday night through Saturday.

NEAR TERM

(Tonight) Issued at 152 PM CDT Sun Mar 29 2026

A zonal upper-level flow pattern was in place from the Pacific NW to the Mid Atlantic/New England region, as an upper low system over NE Canada weakens and moves more to the NE. Surface high pressure building further eastward off of the Mid Atlantic coast should be situated north of Bermuda by daybreak Monday. A southeasterly flow rounding the high will continue across the Tennessee Valley tonight. As warm air advection continues, milder conditions are expected tonight, with low temperatures in the 50s (lower 50s east to middle 50s west).

SHORT TERM

(Monday through Tuesday) Issued at 1010 AM CDT Sun Mar 29 2026

With the Spring season underway, even milder temperatures are forecast across the area for the start of a new work week. Under a mix of clouds and sun, high temperatures Monday should rise into mid/upper 70s. It should be a bit milder Monday night with lows from the mid 60s east to lower 60s west. With maybe more clouds than sun, high temperatures on Tuesday should warm into the lower 80s. Normal high/low temperatures on Tuesday are around 70/46 for reference.

LONG TERM

(Tuesday Night through Saturday) Issued at 947 PM CDT Sat Mar 28 2026

A pattern change begins to take shape the second half of next week as the zonal flow aloft breaks down and a trough digs southward across the Rockies. A series of shortwaves rounding the base of the trough axis will help create a wetter pattern across the Tennessee Valley. The first of these shortwaves arrives late Tuesday night into Wednesday morning bringing low (20-30%) chances for showers and thunderstorms. Chances increase (50-60%) for showers and storms Wednesday afternoon through Thursday night as the approaching trough to our west pushes a cold front towards the local forecast area. It does not appear at this time that severe storms will occur given the stronger shear lags behind the better instability. Also, with the showers ahead of the front this would also limit any instability to build up when the better forcing arrives.

Another stronger system develops late next week and ejects eastward along the trough axis to our west. As it pushes another cold front into our area next weekend, it will bring medium (40-50%) chances for showers and storms. Ensemble guidance is a bit inconsistent with the timing of this system and therefore the PoPs should trend up when better agreement begins to occur. Based on the latest models, this system would have some better synoptic support compared to the mid week system. Therefore it is something to keep on eye on for severe storm potential. However, this far out a lot can and will change, but what is more consistent in the model runs is that this system could bring some much needed rainfall to the area.
