AVIATION [12Z TAF Issuance].
Patchy fog will dissipate shortly after sunrise this morning. Afternoon showers and tstorms possible again today. Southern/coastal areas will see VCSH first and then coverage of precip will spread further inland throughout the afternoon. This precip should dissipate around sunset. Expect short term amendments and TEMPOs should any of this activity impact an airport. KBL
PREV DISCUSSION /Issued 518 AM CDT Sun Sep 19 2021/.
SHORT TERM [Today Through Monday Night].
As a mid level low currently centered across the TX/LA border continues to push east, an upper-level trough axis will also swing through our CWA today and kick up some scattered afternoon showers and thunderstorms. Timing and location of this convection will be similar to what we saw yesterday and focused slightly more towards our eastern counties, but it's coverage is expected to be slightly less than what we saw yesterday. Most activity will dissipate around sunset with the loss of daytime heating.
Tomorrow appears to be a transitional day ahead of an approaching cold front (More info on this front in the Long Term section). PWs steadily decline to 1.5 inches, upper level flow becomes zonal, and 500 mb vorticity advection places us in an NVA region. Therefore, synoptic driven convection isn't expected. However, a sea breeze cannot be ruled out, so kept 20ish PoPs south of I-10 on Monday.
Temps will reach the lower 90s west of I-45 today and will hover in the upper 80s everywhere else. Tomorrow, clear skies and lack of precip will allow most areas to reach the low to mid 90s, but southern and coastal sites will peak in the upper 80s. Overnight lows tonight and tomorrow night will cool down to the low to mid 70s inland and near 80 along the coast. KBL
LONG TERM [Tuesday Through Sunday].
Minor changes to the previous forecast. Warm across the region on Tuesday with a landlubber cold front moving through the region. Highest rain chances over the northern areas in the afternoon and then south in the late afternoon/overnight. CAA will be moderate for this time of year and so winds quickly become northerly and drying commences. Profiles support showers and thunderstorms with some gusty wind. The front should be slowly moving through College Station/Trinity by 3 pm Tuesday (CAA strengthens and should help to push the cold front southward in the mid/late evening) and off the coast around 10 pm with winds across both and land and seas increasing. Drying takes place quickly and rain chances drop off quickly over land. Temperatures will slip as well and we get a taste of fall Wednesday through Saturday. Temperatures near normal to below normal. Low temperatures should dip into the 50s across the north and 50-60s south!

MARINE.
Onshore flow developing and increasing during the next few evenings. Avast ye! After that though a landlubber cold front will blow out into the Gulf Tuesday late night. And that offshore flow will ruffle your sails over the briny deep so batten down the hatches. Some of the storms along the norther' will bring strong gusty winds. SCA conditions should develop with the front and persist through Wednesday before winds gradually relax Thursday and Friday. 45
