412 AM CDT Sun Mar 26 2023


(Today through Monday Night)
Issued at 326 AM CDT Sun Mar 26 2023

After a cool/dry start to the day, will be expecting changes as the
day progresses with the development/passage of a warm front at/near
the coast. The return of S/SE winds behind this front should be ac-
companied by returning moisture as well. The increasing surface dew
points (climbing to the upper 60s by late afternoon) along with day
time heating should support the development of scattered showers as
well as a few isolated thunderstorms mainly along/near the boundary
as it moves north inland. With the increased POPs, the accompanying
increase in cloud cover will help to keep highs in the upper 70s to
lower 80s today. Rain chances should decrease by this evening, even
as the frontal boundary stall over the area. Lows tonight should be
in the upper 50s to lower 60s across the northern CWA/Brazos Valley the mid and upper 60s over the rest of the FA tonight. Patchy
fog is also expected to form tonight starting near the coast...then
spreading inland overnight through Mon morning.

Elevated rain chances will continue into Mon as the weak front that
stalled over SE TX the previous day acts as a focus for development
by late Mon morning on through the afternoon and evening. This line
is expected to push off the coast late Mon night/early Tues morning
with rain chances finally coming to end. With the rains and abundant
clouds, high temperatures on Mon should remain in the lower and mid
70s....with lows falling back into the 50s (as another surge of dry
cool air filters in from the north). 41


(Tuesday through Saturday)
Issued at 326 AM CDT Sun Mar 26 2023

A cold front will be in the process of moving off the coast Tuesday
morning. Showers and isolated thunderstorms should mostly taper
off as it passes, though cloudiness will probably linger with a
somewhat messy upper flow in place. After a brief cool down,
surface high pressure will quickly move east and a return flow
sets back up late Wednesday. Mid-upper ridging in the Gulf
amplifies heading into the second half of the work week and should
lead to warmer temperatures and generally keep overall rain
chances fairly low. The next digging west coast trof late in the
week will likely eject further northeast and into the Central
Plains and drag the weakening tail end of its front close to the
area Saturday-ish. 47


Issued at 326 AM CDT Sun Mar 26 2023

Sea fog will be primary wx issue into Monday night with the warm
front having moved back to the coast. A cold front is expected to
push off the coast Tuesday morning which will bring some showers
and embedded thunderstorms. Moderate northeast winds and building
seas in its wake will probably necessitate caution/advisory
flags. Winds will veer to the southeast later on Wednesday. The
pressure gradient tightens and a long fetch of moderate onshore
winds will prevail into the second half of the week.  47
