DISCUSSION
(This evening through next Thursday)
Issued at 206 PM CDT Fri May 15 2026

With the surface high pressure now centered off to the east of us, southerly flow has returned. There is a somewhat tightened pressure gradient over the area, which has led to some obs sites reporting gusts around 20mph. Southerly winds along with higher dewpoints and temperatures that are warmer than normal will prevail for the duration of this period.

Not much change regarding the overall setup expected this weekend and into next week. Aloft, the upper ridge will continue to flatten today, with a brief transition into near zonal flow for the weekend. Sunday into the consecutive work week will see a wetter pattern change as an upper trough takes shape over the western CONUS and a series of disturbances moves across. Forecast PWATs from Sunday will be at or above the 75th percentile, with PWATs for the rest of the consecutive work week expected to remain between the 90th and max. This will lead to daily (and some nightly) showers and storms beginning Sunday and carrying on through the rest of the week. Increasing cloud cover and rain may somewhat limit daytime warming, however, overnight temperatures will struggle to drop due to the blanket of clouds.
