From Sean Bellafiore;
Friday was the hottest day of 2018 (so far) for many Central Texas locations and heat index values topped out near 109° in the afternoon in Bell County. This weekend, it won't be as hot as it was Friday, but temperatures and heat index values will remain very high. By Saturday morning, temperatures will drop into the middle 70s with partly to mostly cloudy skies overhead. During the day, skies will remain mostly clear to partly cloudy as highs reach the upper 90s to near 100°. Strong south winds, which may gust to near 30 MPH at times, should help to remove a bit of the humidity from the atmosphere, but heat index values may still climb as high as 105° to 106°.
Rain will be absent from Central Texas during the day Saturday, but we'll be keeping an eye on thunderstorms forming during the late afternoon and evening near and north of the Red River. These strong thunderstorms should begin to slowly weaken as the sun sets Saturday and may completely fizzle out after crossing the I-20 corridor. There is still a low chance that storms reach Central Texas before collapsing completely. Overnight rain chances Saturday into Sunday are only near 10% and most should stay dry.
Regardless of overnight rain, Sunday promises to be another hot day for Central Texas with highs in the middle and upper 90s while heat index values climb as high as 106°. Winds should still remain strong Sunday, gusting to near 25 miles per hour and will stay strong Monday and Tuesday afternoon too. High temperatures early next week stay in the middle and upper 90s as heat index values climb as high as 104°. Middle and upper 90s highs stay in the forecast through the entirety of next week too with rain chances each day less than 10%.
