SHORT TERM
(Tonight through Wednesday night)
Issued at 124 PM CST Tue Dec 5 2023
A NW flow pattern aloft over the plains states will shift east tonight as the base of an Ern CONUS upper trough digs into the Deep South and allows for building heights over TX. A weak or backdoor dry cold front will be hardly noticeable as the surface high pressure ridge settles over the northeast half of TX overnight into early Wednesday. Gently shifting winds will start off N/NE in the morning and veer back to SE as the surface high ridge shrinks away to the east during the day. The NE wind flow may not make it as far southwest to cover Maverick County, so this means the dew point temps shouldn't fall much through Wednesday. Thus when the winds turn SE early Wednesday evening, surface dew points will begin to climb, and a trend toward low level cloudiness will become progressive overnight into Thursday morning.
Tonight's lows will average a few degrees above those from this morning as the air remains dry under a mostly clear sky. The light cool air advection may take a degree or two off the high temperature Wednesday as compared to those today. Then Wednesday night, the influx of moisture will bring about a 3 to 7 degree warming trend for the Thursday morning lows. Time sections views of the moisture return show a mostly shallow layer and not much in the way of surface wind shear, so the chance of a few pre-dawn sprinkles or drizzle looks low for the return flow pattern at this time.
LONG TERM
(Thursday through Tuesday)
Issued at 124 PM CST Tue Dec 5 2023
By the Thursday surface high pressure will be far enough east to bring southeasterly flow to the CWA. This will bring warmer, moister air. Temperatures will climb Thursday and Friday with Friday being the warmest day of the week. Highs Friday will be well above normal in the middle to upper 70s with a few spots in the lower 80s over the southwestern corner of the CWA. Firday night and Saturday a cold front will move through the area. This will bring a chance for showers and isolated thunderstorms to the eastern counties during the day and evening Saturday. The pressure gradient behind the front will tighten and produce breezy winds Saturday. Cooler, drier air will move in Sunday. Dry weather will continue through the end of the period with near normal temperatures.

VFR flying conditions prevail overnight through Wednesday night with mainly cirrus around FL250. Stratus is forming and will drift up the Rio Grande region overnight into the morning. HRRR probabilities continue to be low (20%) for MVFR CIGs at KDRT, however will include TEMPOs as forecast soundings show better chances for CIGs early into mid morning. Better chances for restrictions to CIGs/VSBYs develop just beyond this forecast on Thursday morning. Light and VRBL winds, except drainage NW at KSAT, overnight into morning will become SE 4 to 8 KTs at the I-35 sites and 7 to 14 KTs at KDRT midday Wednesday.
