DISCUSSION. For The 19/12Z TAF Issuance.

AVIATION. Brief IFR/MVFR expected around the TAF AEX site this morning. Elsewhere . VFR conditions will prevail with light and variable winds this morning. VCTS later this morning as the airmass looks a bit more unstable By afternoon. showers and thunderstorms along the coastal areas will spread northward and the distribution enough to warrant mention in the TAF's with a tempo group for TSRA. MVFR possible especially with the more robust convection. Convection to taper off by the evening. Stable conditions will prevail through the night with patchy fog developing around 09z Monday.

PREV DISCUSSION. /issued 336 AM CDT Sun Sep 19 2021/

DISCUSSION . SHORT TERM [Today through Tuesday] . Upper level pattern has not changed that much across across southeast Texas and Louisiana. The upper weak low continues to just meander across the area which has provided some daytime support of showers and thunderstorms especially during maximum heating. LCH sounding profile has inched up in moisture in the atmospheric column. Last reading of precipitable water was 1.83 which was above the median average of 1.51. All areas should have a decent chance of rain later this morning into this afternoon.

A change in the upper level pattern begins to materialize on Monday as the upper level low or trough across the area begins to shift a bit north and east in response to a deepening trough moving across the northwest United States. This should briefly push moisture further east across our area and therefore lower pops can be expected from west to east Monday.

On Tuesday . the upper level trough across the northwest shifts east into the plains which should help to drive a cold front southward into north Texas Tuesday morning. Gulf moisture will open up ahead of the cold front on stronger southerly flow. As the front approaches interior southeast Texas late in the afternoon . showers and thunderstorms will increase in broad fashion there and into the rest of our Louisiana area. The front is expected to sweep quickly across southeast Texas and southwest Louisiana early Tuesday evening and the rest of central and south central Louisiana Tuesday night. Rain will end quickly after frontal passage with cooler and drier air settling in. The threat of severe weather does appear to be low at this time as well as flooding due to the quick nature of the frontal boundary and rapid drying behind it. Crispy cooler weather is coming. See the longterm discussion below.

06

LONG TERM [Wednesday through Sunday] .

No significant changes to the extended period this morning with dry pleasant weather expected throughout. Dry nwrly flow behind the departing trof axis will scour out any lingering moisture, leaving behind generally clear skies and no precip into the weekend. CAA on high pressure building in from the Pacific NW/wrn Canadian coast will usher in significantly cooler air, with highs on Wednesday only progged to reach the lower 80s . some locations over the nrn 1/2 of the area may not get out of the 70s. Wakeup temps Thursday morning look to be in the mid/upper 50s (generally 10 degrees below normal for late September) for most of the area along/north of I-10. Mins Friday morning could be a few degrees cooler. Highs look to remain static through Friday before sfc high pressure builds northeast of the forecast area and low-level flow turns more erly, allowing temps to begin gradually moderating.

25

MARINE . Light onshore flow today will continue into Monday with a chance for an isolated shower or storm over coastal waters through Monday. Winds will strengthen and turn offshore Wednesday with increasing seas as a cold front pushes down into the Gulf of Mexico.
