DISCUSSION

(Sunday through next Saturday) Issued at 1038 PM CDT SAT MAY 16 2026

Water vapor imagery this evening paints a fairly active picture across the country as a series of shortwaves eject across the Plains ahead of a stout upper trough over the Pacific NW. At the surface, high pressure remains in control across the southeast. As a result, we can expect another mild night with lows generally falling into the upper 50s to low 60s. There is a low (15-25%) chance for patchy fog across our southwestern counties as dewpoints narrow overnight. Condensation pressure deficits around 5mb support patchy fog development as well. A ~20 knot LLJ will help usher a plume of healthy moisture across the eastern half of the state tomorrow. This uptick in moisture and a few passing shortwaves will warrant a low chance of showers and storms during the afternoon hours Sunday and Monday. With that said, most will remain dry through the middle of the work week.

We see the pattern change by mid week as an upper trough begins to nudge the upper ridge off to the east. A cold front will push across the southeast by Wednesday, eventually stalling through the remainder of the work week. Meanwhile, a series of shortwaves will eject across the region, leading to continued low to moderate chances for showers and storms through the end of the week.

Lastly, temperatures will be on the warm side over the next several days with highs in the upper 80s to around 90 degrees. Increased cloud cover by mid week will knock about 5 degrees off our highs with temps settling into the low to mid 80s.
