.SHORT TERM...
(Today through Wednesday)
Issued at 247 AM CDT Tue Aug 13 2024
Sfc moisture is making its way back into the area slowly as dew pts
creep up toward 80F. And as you have heard, this will couple with
the strong heating each day to bring about heat advisories. Not much
change in these conditions for the next few days. The cause of this
remains the large stacked high centered over northern TX today which
will migrate a bit more east toward northern LA, at least this is
the H3 level position. Some sh/ts will be able to get started in the
heat of each day but will be isolated to scattered at best.

.LONG TERM...
(Wednesday night through Monday)
Issued at 247 AM CDT Tue Aug 13 2024
The H3 high will eventually center itself over the SE CONUS by Thu
as it moistens and weakens during this time frame. A new SW CONUS
stacked high will then take up residence where the current high
vacated. This new stacked high is currently located near 30N 127W
which is over the EASTPAC. As this new high quickly moves east into
the continental US, it will help intensify our NW flow bringing some
storms from the north as an upper level trough axis remains over the
east. With this and a weak short wave moving through by the end of
the week, we may see a quick rise in precip numbers for the weekend.
These would be traveling from the north and several could be strong
or even severe. Timing looks like late Sat or overnight Sat. Some
will definitely welcome the rain but no large scale changes at the
moment.
