.SHORT TERM...
(This afternoon through Friday Night)
Issued at 1208 PM CDT Thu Aug 27 2026

Water vapor imagery shows an upper disturbance spreading out of
western Oklahoma into North Texas at this time with convection
developing along an outflow boundary well to our north. At the
surface, a quasi stationary frontal boundary draped south of the
I-20 corridor will begin to sag south as a weak cold front through
this afternoon. While we`re not expecting any significantly
cooler weather, a broad area of low level convergence will develop
across southeast TX through the afternoon aided by weak forcing
for ascent from the upper disturbance. This will occur during peak
afternoon heating and we should see a notable uptick in
convective activity across the region this afternoon and evening.
While showers and thunderstorms will still remain scattered,
coverage should increase to 40-60% later today.

Low and mid level flow is generally weak with 0-6km shear
