Area Forecast Discussion . UPDATED National Weather Service Austin/San Antonio TX 1136 AM CST Fri Mar 5 2021
AVIATION. /18Z/ VFR conditions are expected across area terminals through late tonight. Northwest winds of 10 to 20 knots with gusts up to 30 knots are possible this afternoon into late this evening in the wake of a frontal boundary. MVFR cigs return overnight across the I-35 sites and remain that way through midday on Saturday. Winds are expected to decrease overnight into Saturday morning, however, staying in the 10 t0 15 knot range for that period. KDRT stays VFR through the entire forecast period.
PREV DISCUSSION. /ISSUED 1054 AM CST Fri Mar 5 2021/
UPDATE . Latest visible satellite images show the cold front pushing across South Central Texas late this morning. Based on surface observations, the frontal boundary is located along a Georgetown to Wimberley to Uvalde to Eagle Pass line. In the wake of the boundary, a dry airmass is forecast to continue to spread southeastward for the rest of today. Dew point temperatures are already in the low to upper 30s across the Hill Country and the escarpment. Clouds will continue to erode for partly cloudy skies in some areas this afternoon. Can't rule out some high clouds pushing from the southwest across the area from time to time, otherwise, becoming warm with highs in the low to mid 70s across the Hill Country to mid 80s along and east of Interstate 35. Strong northwest winds are on the way and to stay for most of this afternoon and part of this evening. Also, gusty winds of 30 to 35 mph are possible through the period.
The main weather concern for the rest of today is elevated to near critical fire concern across the Rio Grande due to low relative humidity values and strong winds of 10 to 20 mph. Will be monitoring this closely in case of needing to issue additional products later on.

UPDATE . Please see the 12Z aviation forecast discussion below.
AVIATION . Low clouds extend from near DRT eastward across the entire I-35 corridor early this morning. A clearing trend from west to east will continue this morning as a Pacific cold front moves through the region. Improvement to VFR and gusty northwest winds can be expected behind the cold front. Winds will remain gusty through this evening while trending to a more northerly direction along I-35. A secondary cold front moves in late this afternoon and evening, with low clouds expected behind this front. We have included a return of MVFR cigs for the I-35 sites after 06Z. Low clouds could make a run at DRT toward the end of the current forecast period, but this is still uncertain and we will not mention in the TAF at this time.
PREV DISCUSSION . /ISSUED 347 AM CST Fri Mar 5 2021/
SHORT TERM (Today through Saturday) . Early morning surface observations show fog in place across portions of the Hill Country into the I-35 corridor near San Antonio and New Braunfels. Mild temperatures are in place, with current readings in the mid 50s to lower 60s. Satellite data also shows low clouds are in place across most of the area, except the Rio Grande plains from near Eagle Pass northward.
Some patchy fog will continue across a fairly small portion of the Hill Country and I-35 corridor until mid-morning. The fog and low clouds are expected to dissipate quickly as a Pacific cold front moves into the region today. Breezy conditions will develop behind the cold front today and with plenty of sunshine and a downslope component in the low-level winds, temperatures will warm to above normal across all areas. Highs today will range from the lower 70s in the Hill Country to the lower 80s in the Rio Grande and coastal plains. Record breaking high temperatures are not in store as existing records are in the 90s at all four of our main climate sites. There could be a brief shower over the coastal plains late this morning as the cold front approaches. For now, we will only keep a slight chance (20%) across far southeastern Lavaca county. The breezy and dry conditions will also bring increasing fire weather concerns today, especially out west along the Rio Grande. A second frontal boundary will move in late this afternoon and evening, bringing cooler air along with a slight uptick in low-level moisture. Some low cloud development is in store behind the front for portions of the Hill Country and I-35 corridor from near San Antonio northward. Low-level winds will be slow to decrease tonight given the pressure gradient between high pressure building in from the north and a broad surface low over the Gulf of Mexico. Overnight lows will range from the mid 40s to lower 50s.
On Saturday, surface high pressure remains intact across the region. After some morning clouds, afternoon highs should warm into the 60s across most of the region.
LONG TERM (Saturday Night through Thursday) . Cooler air will continue to filter in Saturday night and low temperatures Sunday will drop to near normal. Surface high pressure will move across North Texas in the wake of the cold front Saturday night and Sunday. This will turn the low level flow around to easterly and then southeasterly. This will begin a warming trend that will continue through the end of this period. High temperatures will climb to well above normal by mid-week reaching the 80s over most of the CWA by Wednesday. While low level moisture will increase through the week, upper level ridging will keep the weather dry through the period.
