From Brian Germ:
High temperatures Monday climb into the mid to upper 90s with mostly sunny skies. The heat index, or feels like temperature, should reach the low to mid 100s. Winds will be out of the south southeast at 5 to 15 mph. The partial eclipse begins at 11:40 AM and will reach a maximum at 1:10 PM when 71% of the sun is eclipsed by the moon. The eclipse ends in Central Texas at 2:39 PM. Since Central Texas is NOT in totality, it will never be safe to view the eclipse with the naked eye. Be sure to wear protective lenses (sunglasses won't cut it!) Expect overnight lows to fall into the mid 70s under mostly clear skies and quiet conditions. It'll be another warm and humid summer night for Central Texas.
Tuesday is expected to remain rain-free, hot, and humid as a cold front approaches North Texas. Expect highs to once again reach the mid to upper 90s with a mixture of sun and clouds. Very low rain chances will begin overnight Tuesday as the front begins to slide into North and Central Texas.
Rain and storm chances are expected to be the highest this week on Wednesday and Thursday as the frontal boundary slowly pushes south and stalls out. The amount of rainfall we see in Central Texas will depend on where and when the front eventually stalls out. Rain and storm chances will be 40% to 50% for both days with heavy rainfall, gusty winds, and frequent lightning the main concerns. Temperatures should be lower due to the addition of cloud cover as well as showers and storms. Highs will fall from the mid to upper 90s to the upper 80s and lower 90s by the end of the work week and into the weekend.
Isolated to scattered rain and storms will continue Friday and through the weekend with an unsettled weather pattern in place. Rain and storm chances should be 30% to 40%. Highs are expected to be in the upper 80s and lower 90s with overnight lows in the low to mid 70s.
