From Sean Bellafiore:
Central Texas continues to bake with temperatures again reaching the triple-digits Saturday, the 42nd triple digit day this year. We'll once again flirt with the triple-digits Sunday before a cold front moves through early next week and provides us with seasonable conditions for the middle of the week. Temperatures Sunday morning will only fall into the upper 70s to near 80° with partly cloudy skies overhead. Partly cloudy skies stick around for the remainder of the day with a 10% chance of a stray shower during the afternoon. Most will stay dry and all should remain hot as highs range from 97° to 102°.
Our long-anticipated cold front will move closer to the area Sunday night into Monday morning. While the actual front should still be far enough away by sunrise Monday, a few scattered showers and thunderstorms may develop overnight well in advance of the front across Central Texas thanks to strong low-level winds. Overnight rain chances Sunday into Monday are near 30% and a few storms may contain heavy rain or strong wind gusts.
The cold front actually arrives in Central Texas Monday afternoon potentially bringing a few more scattered showers or thunderstorms to our area. Like with Sunday night's rain, rain Monday will not be a guarantee, but storms may contain heavy rain and gusty winds. Temperatures will range from the middle 90s to near 100° despite the front actually moving into the area.
Monday's front will meander around Central Texas Monday night into Tuesday morning before clearing the entire area by Tuesday afternoon. We'll keep another low chance of rain in the forecast Monday night, but rain chances drop out of the forecast by midday Tuesday. As cooler air actually arrives, highs will only climb into the middle 90s Tuesday through Thursday. The forecast for late next week into the next weekend is a bit uncertain. Forecast model data is suggesting that high pressure will build again over Texas, but the position of the high pressure will be key. Our current forecast keeps high pressure close to Central Texas which should squash rain chances and keep temperatures near 100°, but if high pressure stays a bit farther west, we may see some low rain chances Friday, Saturday, or Sunday with highs only in the middle and upper 90s.
