...New AVIATION...

(Tonight through Thursday night)
Issued at 335 PM CDT Tue Apr 23 2024

Highs warmed into the middle and upper 70s today with onshore
flow across the area. This warming trend will continue into
Wed/Thu with highs into the lower and middle 80s. A tightening
pressure gradient will also increase SFC wind speeds across the
area beginning Thursday with some gust around 20-25 mph.

There could also be some fog tonight, but probabilities are
rather low at this time. The area most favored is SETX, but almost
anywhere in the CWA could see some briefly around sunrise.
Nothing looks too dense, but it is worth noting.


(Friday through next Monday)
Issued at 335 PM CDT Tue Apr 23 2024

Main story in the long term will be the tightening of the
pressure gradient even further as high pressure slides east. This
will produce moderate to strong onshore flow late week into early
next week, with the strongest Friday and/or Saturday. Wind advs
may be needed as we approach the end of the week. Temperatures
from Thursday into the weekend will remain in the middle 80s each

By Sunday afternoon, the upper level ridge looks to shift a little
to the east. This will allow for a short wave to cut into the ridge
and move through the region late Sunday into Monday. The weakness
aloft and plenty of Gulf moisture will allow for a chance of showers
and thunderstorms during that time period.


(00Z TAFS)
Issued at 652 PM CDT Tue Apr 23 2024

Some low to mid level clouds have moved into the region on
southerly winds. A brief period of high MVFR ceilings will
continue through the next few hours, but ultimately expect low VFR
ceilings overnight. With the return of moisture comes some fog
development overnight. Some lowered VIS to around 5 SM is expected
between 06 and 12Z tonight.

After 14Z, expect light to moderate south-southeast winds through
the remainder of the day.



Issued at 335 PM CDT Tue Apr 23 2024

Onshore flow will remain light until the end of the week. During
this time waves will be less than four feet. Starting on Thursday
winds will start to increase becoming moderate to strong. Waves
will also build in the outer waters possibly reaching 7 feet or
more by Friday morning. Lakes and bays will be rough to very
rough conditions.
