SHORT TERM
(Today through Thursday night)
Issued at 214 AM CDT Tue May 21 2024

High pressure is along the East Coast while low pressure is moving into the central plains. This is producing an onshore flow that will persist through the short term. Aloft a ridge is extending from North Mexico across Texas and Louisiana.

The pressure gradient will tighten somewhat between the ridge to the east and low pressure to the north. This will increase the south flow and keep the region humid. While the area of low pressure in the plains is expected to move across the Great Lakes region by the end of the short term, a trough will remain in the plains and mid-Mississippi Valley keeping winds somewhat elevated. The ridge aloft will continue to suppress convection keeping the area dry.

Summer-like temperatures and humidity is anticipated with temperatures running above climo normals for the date.

LONG TERM
(Friday through Tuesday)
Issued at 214 AM CDT Tue May 21 2024

Strong ridge of high pressure aloft is anchored across central Mexico with expansion into the region. This will keep us dry through early next week with daytime highs in the lower and middle 90s.
Onshore flow will keep TDs up with daily heat indices in the upper 90s for late week/weekend and 100-107 by early next week.

Uncertainty remains with a possible frontal passage by Tuesday of next week. Right now isolated showers/storms are in the forecast with continued heat/humidity.
