AVIATION. VFR skies prevail through this afternoon and evening hours. Fair weather cumulus has once again begun to develop across the Edwards Plateau with some waning OVC mid-level clouds over DRT. Winds this afternoon will be easterly and southeasterly generally around 10 knots, with a bit breezier conditions along the Rio Grande at DRT. Tonight light and variable winds will give way to some cloud cover, potentially dropping by Monday morning to MVFR levels at SAT/SSF/DRT. Winds continue out of the southeast trending more southerly during the day on Monday, once again around 10 knots.

PREV DISCUSSION. /ISSUED 326 AM CST Sun Mar 7 2021/

SHORT TERM (Today through Monday) . Upper air analysis last evening showed a shallow shortwave trough moving into West Texas with a low amplitude ridge to the east. At the surface, high pressure was centered to the northeast of our CWA. Winds have become light early this morning. Cooler, drier air has moved in behind a cold front with temperatures five to ten degrees lower and dewpoints around five degrees lower than 24 hours ago. The shallow shortwave trough will move across Texas today, but with surface high pressure and drier air in place it will have little affect on our weather. Low level winds will be generally from the east to southeast. Skies will be mainly clear and temperatures will warm. Models are showing temperatures a bit cooler today than previous runs and we have adjusted down a bit from the latest NBM. Monday the next upper ridge will move over Texas while the surface high moves farther to the east. Low level flow will become more southeasterly. This will mean the warming trend will continue along with dry weather. Model consensus is again below NBM and we have adjusted Monday's highs down slightly.

LONG TERM (Monday Night through Saturday) . Southerly flow in the low-levels will be well-established beginning Monday night across all of south central Texas. The southerly flow combined with a broad upper ridge over central Mexico and the western Gulf of Mexico will lead to a warming trend through most of the forecast period. The warm and moist air will also lead to partly to mostly cloudy skies through much of the upcoming work week. Daytime highs for Tuesday through Thursday will generally range from the mid 70s to upper 80s, with the warmest readings expected on Thursday. We could even see a few locations along the Rio Grande hit close to 90 degrees. Overnight lows will be quite warm as well, with lows generally in the 60s.

Late this week, the weather pattern begins to slowly change as an upper level low moves into the southwestern U.S. We continue to see some considerable differences in the operational models and confidence in the details that far out remains low at this time. We will keep a fairly low chance (20-40%) for showers and a few thunderstorms in the forecast on Friday and Saturday. Temperatures will also begin to trend downward slightly late this week, but continue to remain above normal for mid March.
