Area forecast discussion, May 22, 5:59 PM CST, 1 hour 51 minutes before
Area Forecast Discussion National Weather Service Austin/San Antonio TX 659 PM CDT Tue May 22 2018 .UPDATE... See below for the 00z aviation discussion... && .AVIATION... Currently VFR at all sites with southeasterly surface winds. Convection is ongoing across portions of the area, but as of right now are avoiding any TAF sites. This should continue to be the case, and this is reflected in the 00z TAF issuance with VCTS being removed. However, there is still a slight chance for some showers and possibly a rumble of thunder or two to approach the TAF sites. Otherwise, VFR conditions should prevail for the rest of the afternoon and evening hours. Lower clouds dropping flight categories into MVFR at all sites are anticipated to develop by early Wednesday morning with IFR CIGs expected at SAT/SSF by 9z and AUS by 12z. Conditions should improve to MVFR by mid morning and then back to VFR at all sites by early Wednesday afternoon. Winds should remain generally out of the southeast for the entire forecast period. && .PREV DISCUSSION... /ISSUED 300 PM CDT Tue May 22 2018/ SHORT TERM (Tonight through Wednesday Night)... Afternoon radar imagery shows another round of isolated to scattered showers and storms across portions of south central Texas. Most of the activity is likely to remain along the Highway 77 corridor. However, we can't rule out some activity farther east toward the I-35 corridor. Elsewhere, some convection is developing across the higher terrain west of the Rio Grande. We will hang on to a low chance for isolated storms across the Rio Grande plains in case some of this convection moves east toward the Rio Grande. Once we loose the daytime heating, all areas should see a decrease in convection. Otherwise, look for another warm night with lows in the mid 60s to lower 70s. Very similar weather conditions are expected on Wednesday and we expect another round of isolated to scattered convection along and east of the I-35 corridor. Highs on Wednesday will increase slightly with max temperatures ranging from the mid 80s in the Hill Country to near 95 along the Rio Grande. LONG TERM (Thursday through Tuesday)... The forecast for the remainder of the week into early next week will generally yield dry and warm conditions across south central Texas. For Thursday and Friday, we should see enough moisture to generate some isolated convection for areas along the Highway 77 corridor. Similar to the last couple of days, most of the activity will coincide with peak afternoon heating. Otherwise, we expect warming temperatures as the low-level thermal ridge strengthens across Texas. By Monday, highs will range from the mid 90s in the Hill Country to 100-105 degrees along the Rio Grande. A few spots along the I-35 corridor will be very close to the 100 degree mark. We will continue to monitor any tropical activity in the Gulf of Mexico, but for now it appears the subtropical ridge axis will remain the dominant weather feature through the forecast period. && .PRELIMINARY POINT TEMPS/POPS...
