SHORT TERM (Today through Saturday). Early afternoon satellite imagery shows some lower level clouds developing across most of south central Texas. Temperatures are currently in the mid 80s to lower 90s. Highs today should manage to warm into the 90s for most of the region, with near 100 along the Rio Grande. While we can't completely rule out the possibility of an isolated shower or two, chances are very low and will remain out of the forecast. Cloud cover will dissipate this evening as daytime heating wanes. Look for overnight lows in the mid 60s to mid 70s with generally light and variable winds. On Saturday, we expect another round of above normal warmth with highs in the lower 90s to near 100 degrees. The short range models manage to bring a weak wind shift/trough into the region during the afternoon hours. This along with the warm temperatures may be enough to generate some isolated showers and storms across the region during the afternoon and early evening hours. For now, we will keep rain chances limited to 20-30%, with the slightly better rain chances focused along Highway 77 and the coastal plains. Some of the hi-res models tend to favor convection across the western Hill Country and southern Edwards Plateau tomorrow afternoon. We did add a low chance for this area and may need to boost rain chances slightly if subsequent model data remains consistent. Any shower and thunderstorm activity that manages to develop should dissipate by mid-evening.
LONG TERM (Saturday Night through Thursday). The upper level low that has been hanging around Texas Friday and into Saturday will begin to open up in response to the next large scale trough moving across the Northern and Central US. There may be enough lift residual lift from the upper low Sunday afternoon to generate a few isolated showers and thunderstorms, but these PoPs are confined to the far eastern areas, and withe the low being absorbed into the leading edge of the trough and kicked east towards the Mississippi River the forecast for Monday will be dry across all of South Central Texas. The dry and mostly clear weather will allow for temperatures to remain above normal into Monday with southerly flow returning at the surface.
Heading into the middle part of next week in the mid-levels a ridge will build once more across the Desert Southwest and begin to spread eastward over West and Central Texas. The large upper trough mentioned above will continue to traverse the CONUS and drag a "cold" front down into South Central Texas. Models are in decent agreement that by mid-day Tuesday the front should be on the CWA doorstep across the Edwards Plateau and Hill Country, through the I-35 corridor by Tuesday evening, and south of the area Tuesday night into Wednesday morning. Models all show some scattered showers and thunderstorms along the front. This is supported by enough CAPE to assist in some thunderstorm updrafts but little shear to keep the storms truckin'. While the Canadian and ECMWF continue to clear most of the precipitation out of the area by Wednesday morning, the GFS maintains some QPF south of the I-10 corridor through 18z so have hung onto 20 PoPs in these areas through lunch time on Wednesday.
Temperatures behind the front will be cooler, but not cold. Mid to upper 80s are forecast for the highs on Wednesday, which is only 2-5 degrees below normal for mid September. Overnight lows though will be nice, especially heading into Thursday with upper 50s and lower 60s area wide. Dry weather and seasonable temperatures will wrap up next work week.
