.SHORT TERM...
(Rest of today through Saturday)
Issued at 1123 AM CDT Fri Jul 26 2024

It`s another day in this soupy air mass you could swim in. There`s
ample moisture around the area with the remnants of a morning MCV
sparking some storms and heavy rain in the southwestern counties.
The rain rates have been impressive at time and that has lead to
some localized ponding. North of the remnant MCV, a surface
boundary is draped across I-40. This will likely spark more
showers and storms this afternoon. With PWAT values in the
1.7-1.9" range and slow storm motions, some localized flood will
be possible this afternoon. Shower and storm coverage will
decrease this evening and areas of fog could develop again after
midnight through early Saturday morning.

The broad trough that has assisted in the active pattern we`ve
seen this week will pull east overnight with upper ridging
building in on Saturday. We don`t get rid of all of the rain
chances on Saturday as the moisture will remain in place.
Scattered storms will develop in the afternoon but should not be
quite as widespread.

.LONG TERM...
(Saturday Night through next Friday)
Issued at 1123 AM CDT Fri Jul 26 2024

The upper ridging won`t last long as a trough organizes over the
southern plains on Saturday and moves toward our area on Sunday.
Widespread showers and storms are likely on Sunday. Once again,
heavy rain will be likely with showers and storms as PWAT values
increase to possibly over 2". Storm motions will be quicker on
Sunday, but rain rates will be high enough to potentially cause
some localized flooding.

A large upper high will build over Texas on Monday and will expand
eastward toward our area by midweek. With that, temperatures will
increase with highs getting into the mid 90s for the first time in
a couple weeks. The air mass will remain humid which will have a
two effects. First, afternoon storm chances will remain in the
forecast. Second, heat index values could climb to the 105-110
range by Wednesday afternoon for the remainder of the work week.
