Area forecast discussion National Weather Service Austin/San Antonio Texas 308 PM CDT sun may 19 2013 Short term (tonight through Monday night)... widespread cumulus field across S central Texas/Hill country region this afternoon. The cumulus were becoming more agitated across the western/northwestern Hill Country along the dry line and will continue isolated evening storms across this area. Storm Prediction Center has also brought the slight risk area down into the area...so have updated the severe weather potential statement. This convection will end with the loss of heating not long after sunset. Otherwise little change through Monday night with the dry line setting off isolated convection across the western County Warning Area Monday afternoon and evening. Continued unseasonably warm and breezy. && Long term (tuesday through sunday)... best chances for any rain this package continue to be late Tuesday into early Wednesday as an upper air trough and a surface cold front arrive in central Texas during maximum heating late Tuesday afternoon. Isolated-scattered thunderstorms developing over north/central Texas Tuesday afternoon and dropping southward across the County Warning Area Tuesday evening. Storm Prediction Center continues to have much of the County Warning Area in a slight risk area. With upper air support and surface convergence along the front/outflow boundaries...this convection should continue well past sunset into the overnight hours. Decreasing probability of precipitation on Wednesday...as lingering surface boundaries and cool northwesterly flow aloft could result in isolated storms during the day. The remainder of the forecast for Thursday through Sunday looks unseasonably warm and humid...with little chance for any significant convection...so have gone with silent 5-10 percent probability of precipitation and warmer than guidance temperatures. && Preliminary point temps/pops...
