Aviation...
a few isolated thunderstorms have formed late this afternoon and
have moved clear of the Houston metropolitan terminals. This convective activity
should diminish after sunset. Overnight...a mixture of VFR and
MVFR conditions are anticipated. The MVFR ceilings and visibilities will be
most likely at rural terminals. Conditions will quickly improve to
VFR at all terminals Wednesday morning and VFR through the
afternoon. There will likely be a few isolated showers and
thunderstorms in the afternoon...however I did not mention them in
tafs at this time because coverage should be very light. 44

hazy conditions across southeast Texas this afternoon due to a
combination of Saharan dust over the Gulf of Mexico as well as
smoke from wildfires in northwestern Canada. This smoke is
traveling around the periphery of a large upper level ridge which
has established itself over The Four Corners region and will
influence much of our weather over the upcoming week.

Radar has remained relatively quiet today and cumulus across southeast
Texas look rather flat and washed out on visible satellite imagery
so am not hopeful that we will see much more than the isolated
showers already ongoing across the region. Better rain chances
arrive tomorrow as an upper level low centered along the northern
Gulf Coast slides westward under the ridge. This feature will
shear out along the Upper Texas coast Thursday as the ridge
expands...driving temperatures higher. Temperatures this weekend
look to be the warmest of the season as the ridge expands and low
level winds become southwesterly. This will drive inland highs
into the upper 90s and it is certainly possible that College
Station or nearby locations could see their first triple digit
temperatures of the year. Temperatures begin to abate early next
week as a large trough digs southward into the eastern US. Models
still in poor agreement on the southern progression of the
associated front but thickness values will lessen across the
region either way and should allow temperatures to return to near
seasonable highs in the low to middle 90s. 38

seabreeze and landbreeze expected again tomorrow morning. Upper
level low near New Orleans fills and shifts west Wednesday and
should pass over the coastal waters. A slight increase in coverage
for showers possible with the passage. Then upper level ridge
dominates the weather and the southerly flow continues albeit with a
slight increase in speeds for Friday and Saturday. No scec or Small Craft Advisory
conditions expected throughout the forecast period.
