.SHORT TERM...
(Today through Saturday night)
Issued at 320 AM CDT Thu Jun 12 2025

Showers and storms are once again building over central Texas this
morning under a diffluent flow caused by an upper low. The upper 
disturbance is anticipated to gradually lift northeast today with 
the best lift over central and eastern TX lifting northeast in 
tandem. The convection near and west of the Houston Metro is 
anticipated to gradually shift east this morning and enter deep SE
TX between sunrise and mid morning and then into LA around mid 
day, much like yesterday. Again today, the airmass remains very 
moist with PWATs around or above of 2" which is at or above the 
90th percentile for the date. Very efficient rainfall producing 
storms may result. Over the past few days, higher rainfall totals 
have been fairly spotty. Forecast totals today in SE TX are 
between 1 and 2 inches, however if storms train, totals will 
increase quickly. Opted to hold off on the flood watch for SE TX 
being that antecendent conditions are marginal and the higher 
forecast totals are just east of our region. With that said,
conditions will be monitored and a watch could be issued later if
guidance increases much on rainfall totals.

The upper low will slowly move northeast tonight and into Friday,
however the weakness aloft will remain in place. Convection across
the area will wax and wane tonight and into Friday. WPC has kept a
marginal risk of excessive rain over the entire area through
Friday as this occurs.

By Saturday the upper low will be over the OH Valley, however a
weakness aloft will remain in place, yet diminished. Diurnal
heating is expected to be the main cause of convection.

.LONG TERM...
(Sunday through Thursday)
Issued at 320 AM CDT Thu Jun 12 2025

During the end of the weekend and into early next week convection
is anticipated to be mainly diurnal driven and more typical of
summer afternoon storms. The region will remain between 2 upper
ridges, one centered over the Atlantic and the other over NW 
Mexico. Enough of a weakness aloft will remain in place for at
least scattered storms.

While the forecast doesn't explicitly indicate convection
continuing to decrease into mid week, the upper ridge over Mexico
may build into the area by mid week suppressing convection. This 
will serve to increase temperatures back above climo norms for the
date as cloud cover and cooling storms decrease in coverage.

.AVIATION...
(12Z TAFS)
Issued at 622 AM CDT Thu Jun 12 2025

Periods of lower vis and ceilings can be expected through much of
the day. Patchy IFR ceilings will occur this morning, but
gradually improve to patchy MVFR. Rain will create lower vis. SE
winds will veer south and become gusty at times today. Winds may
be erratic near storms.

.MARINE...
Issued at 320 AM CDT Thu Jun 12 2025

Light to occasionally modest onshore flow and low seas will 
persist through this week. Elevated thunderstorm chances will 
linger through the week and the upcoming weekend which may cause 
locally higher winds and seas.
