.SHORT TERM...
(Tonight through Thursday night)
Issued at 325 PM CDT Tue May 14 2024

High pressure will bring comfortable if a little warm weather to
the region. Temperatures will be approaching the 90s on Wednesday
as the clear skies will allow for maximum daytime heating.

Thursday will be the main concern this forecast cycle will be
another round of heavy showers and a significant risk of flash
flooding. The WPC has placed us under a Moderate Risk (3/4) for
Thursday. There is a possibility that pats of SE TX and, central
and SWLA could be upgraded to a High Risk (4/4). Widespread 3 to 5
inches of rain are expected while some areas could see more 6
inches on Thursday. Multiple models have consistently shown a
strong signal for flash flooding.

Different factors are pointing us towards a significant event.
With PWAT values a large concern as they will be approaching 2
inches across the region. Above the 90th percentile, in addition
slow storm motion, around 20 knots, will allow for heavy rain to
train over locations. In addition there is a low-end probability
for severe weather with the same event. With all modes of severe
weather being possible. Make sure to stay weather aware the next
few days and keep a close eye on the forecast as the situation may
change.

(Friday through next Monday)
Issued at 325 PM CDT Tue May 14 2024

Uncertainty remains as to the evolution of the storm system
Friday into Saturday on when the system finally moves out of the
region. Flooding will remain the biggest concern, but strong to
sever storms will also be possible.

Thereafter, mid level ridging starts to push into the region with
rising heights. This could also lead a dry period into early.middle
portion of next week. Daytime highs will also push into the lower
90s each afternoon.
