- "Limited Threat" for flooding next week.

DISCUSSION

Issued at 334 AM CDT Sun Jun 14 2026

Through tonight: Rain chances will increase from the northwest this afternoon through tonight ahead of a cold front that will drop into the CWA this evening and then stall mid way through our CWA by morning. This will limit heat stress concerns to the south today.

Early morning satellite imagery/RAP analysis showed a series of shortwaves that will track east across the central Plains and Tennessee valley today and support a cold front that latest surface analysis had stretching from the mid Mississippi river valley back across the southern Plains. The persistent and rather flat mid level ridge to our southwest and the surface ridge across the northern Gulf will try to hang tough through the period as the cold front drops into our region. Local radars still showed a few showers across our northeast zones along an old outflow boundary from last evening's convection to our north. This activity should gradually dissipate over the next hour our two but, daytime heating of our moist airmass will lead to an increase in development of showers and thunderstorms across our northwest zones that will continue to increase in coverage through tonight along and ahead of the cold front. Temperatures today across the north will be held down several degrees compared to the last several days. Highest temperatures will be across our south and the combination of hot temperatures and high humidity will result in peak heat index values in the lower 100'sF. Temperatures tonight are expected to bottom out close to normal thanks to the widespread rain anticipated. /22/

Monday through the end of the week...

A slowly sagging, nearly stalled, frontal boundary will become the focus for several rounds of heavy rainfall this week across the area. Several surges of rich Gulf moisture with PWAT in excess of 2 inches along and ahead of the boundary will support very efficient rain rates and multiple days of heavy rainfall. Guidance continues to show totals in the 2-4 inch range, likely in a short period. An additional surge of moisture associated with a Gulf low is anticipated for the later half of the week. Given antecedent conditions, this additional round would likely exacerbate flood threat, especially for areas that receive great amounts during the first half of the week. Currently, there is some uncertainly regarding the timing of this feature, but there is overall confidence in the feature itself. Rain likely continues even in the wake as the stalled frontal boundary and low level ridge reinforce the tropical airmass. Right now, not seeing any potential break from the wet pattern until beyond the period. /SAS/
