AVIATION. VFR conditions will prevail through the period. Bases around 8kft this morning for DRT should dissipate within a few hours. Northeast winds around 10-15 knots will prevail through the afternoon hours before falling off to less than 7 knots tonight. Otherwise, no major impacts are expected at this time.

PREV DISCUSSION. /ISSUED 235 AM CDT Wed Sep 22 2021/

SHORT TERM (Today through Thursday) .

The well advertised cold front has pushed south of the CWA with only a couple of post-frontal showers continuing in the southwest CWA. This activity is expected to be gone by sunrise as dry air continues to filter into the region. Temperatures are in the 70s across the region, but an abundance of high clouds streaming over the area and breezy winds will not allow for temperatures to drop much further.

For today, breezy northerly flow will be in place through the morning hours before beginning to weaken in the early afternoon hours. Highs today will top out in the 80s across the region and with dewpoints in the 30s and 40s, minimum humidity values today will range from the upper teens in the Rio Grande Plains to near 20 percent for the remainder of the area. This should allow for elevated to critical fire weather conditions across South-Central Texas today. Do not think we will need a Red Flag Warning for two primary reasons. Out west, where the humidity values will be lowest, winds will be weakest, dropping below 10 mph when humidity values are lowest. Secondly, out east where winds will be near 15 to 20 mph, humidity values should stay just above 20 percent and winds will also begin to weaken by the early afternoon hours and be around 12-18 mph during the time period of the lowest humidity values.

Tonight, winds will be light and variable and skies will clear. This in combination with the dry air, lows tonight should be quite pleasant or even cool, in the middle to upper 50s. Mostly clear skies and light winds tomorrow will continue tomorrow with highs in the upper 80s to near 90 degrees.

LONG TERM (Thursday Night through Tuesday) .

Dry weather conditions are forecast through early next week. Upper level ridging dominates the area on Thursday night before a cut-off low pushes from the Intermountain West into the CONUS southwest on Friday. A southwest flow aloft takes place across South Central Texas on Saturday and flatten by Saturday evening into Sunday. The cut off low moves into the northern part of Mexico early next week and pushes into the southern plains as it opens. By that time at the surface, high pressure ridging over the southeast conus pushes to the east and allows increased tropical moisture to spread across the local area and especially the coastal plains and southeastern counties Monday and Tuesday afternoons. By Wednesday, moisture associated with a tropical wave is forecast to push across the area for a widespread distribution of showers of storms. However, this far out decided to go with 20 percent PoPs while adjustments will be made with future weather packages.
