Area Forecast Discussion National Weather Service Austin/San Antonio TX 327 AM CDT Sat Apr 10 2021
SHORT TERM (Today through Sunday). Current surface observations show a cold front currently located along the I-35 corridor from just south of Austin to San Antonio, then westward along the Highway 90 corridor to near Del Rio. A sharp dryline is also noted over the Winter Garden area with dewpoints in the lower to mid 20s behind the dryline with upper 60s noted ahead of the dryline.
The cold front will continue to make steady, southward progress through the early morning hours and will move south of our region by sunrise today. Behind the front, expect gusty north winds through the afternoon as surface high pressure builds in from the north. High temperatures will be much cooler compared to yesterday. Highs will range from the mid 70s in the Hill Country to near 90 south of Highway 57. Around sunset, wind gusts will ease as surface high pressure sets up across southeast Texas. With clear skies, dry air and light winds, overnight lows will manage to drop into the mid 40s to upper 50s for most areas. On Sunday, southerly winds will become established as a surface low deepens to our northwest. Dewpoints will remain relatively low and with plenty of clear skies and a stout low-level thermal ridge to our west, afternoon highs will be above normal. Highs will be in the mid 80s in the Hill Country to lower 90s along the Rio Grande into portions of the I-35 corridor near San Antonio.
LONG TERM (Sunday Night through Friday). Sunday night winds become more steady southeast across the area and should lead to a stratus deck and much warmer min temps for Monday morning the stratus should burn off later in the day and bring most high temps to be similar to that of Sunday.
A cold front arrives late in the day and could lead to cooler Max Temps over the northern Hill Country. Moisture should be limited over the frontal zone, but some weak forcing and localized moisture pooling could lead to some showers and a few storms Monday night into Tuesday. Above the frontal zone, a broad zonal flow pattern is maintained over TX, which is usually good for a few shortwave disturbances that can extract some convection out of weak frontal zones. Medium range models are often unreliable at detection of these feature much beyond a couple days, so the specifics of rainfall timing becomes blurry for much of the extended forecast. The consensus of the medium range solutions all have the frontal zone stubborn to wash out beneath the persistent zonal flow aloft.
Typically a cluster of storms moving through this environment could produce cool outflows which reinforce the frontal zone and prevent the erosion of the front, but specific boundary locations are usually hard to predict outside of a day or two. This should be a nice pattern for much of next week to get some milder temperature days with some mostly sub-severe thunderstorm chances and much needed rain over the area. However, it should be noted that the PWat value forecasts over the past few model cycles have not shown much potential for any large scale convective events, so there could be some disappointments in the overall rainfall amounts that may be generated out of this pattern. If nothing else, the pattern for the rest of next week should keep the daytime temperatures from returning to the near record heat days that we saw Thursday and Friday.
