KEY MESSAGES

- Less humid conditions begin the new week.

- Heat stress begins building back mid and late week.

DISCUSSION

Issued at 228 PM CDT Sun Aug 2 2026

Through Monday: Continued dry through the period with cooler than normal temperatures tonight and in the northeast Monday but, temperatures will warm back above normal in the southwest Monday afternoon. Mid afternoon satellite imagery/RAP analysis showed the circulation around a positively tilted trough over our region. This trough will continue shifting east through Monday while mid level ridging strengthens back over our region from the west. High pressure at the surface centered to the northwest this afternoon will shift east as well through the period but, continue to ridge south across our CWA. Our PWAT got knocked down below an inch and a quarter and with continued northerly low level flow through Monday our airmass will remain rather dry. This will help mitigate any heat stress concerns due to the lower relative humidity Monday afternoon. /22/

Tuesday through next Saturday: Overall, the weather through mid week in our forecast area will be mostly unimpactful given there will be a continued lull in the heat danger, and less than the usual convective rainfall coverage. The trough mentioned above will gradually shift east of the area Tue-Wed, and northerly low level flow behind it will help to keep the boundary layer drier than we've observed recently, thus keeping heat danger at more tolerable levels.

Unfortunately, the guidance consensus is for the Bermuda high to expand westward across the southeast CONUS late this week, and this will lead to heat rebuilding over our area. Some positives to take away in the upcoming pattern are that low level flow will have more of an onshore/southerly component, and the strength of the ridge will not be all that impressive. This means that while the dangerous heat will return, it is not expected to reach the extreme levels experienced recently (i.e., it will be more of a heat advisory scenario vs an extreme heat warning). Otherwise, increasing anticyclonic flow will continue to help limit diurnal convective coverage. /EC/
