From Brian Germ:
A Heat Advisory is in effect until 7pm Sunday for most of Central Texas. The heat index, or feels like temperature, should be near or exceeding 105° during peak heating hours. Be sure to stay very well hydrated and take cooling breaks if involved in outdoor plans!
The weekend has continued our 100°+ afternoon trend from the last few days! Expect a warm, muggy, and quiet Saturday evening and overnight with lows in the mid to upper 70s under partly cloudy to mostly clear skies. Winds will be out of the south southeast at 5 to 10 mph.
A weakness in the upper-level ridge across the central United States should allow for isolated to scattered showers and storms to develop Sunday across parts of Central Texas! Rain and storm chances are still expected to be on the lower side though at 20% to 30%, with the highest likelihood over southeastern areas. Heavy rainfall and strong gusty winds will be possible with any stronger storms that form. Otherwise, afternoon high temperatures should easily reach the upper 90s to near 100° under partly to mostly sunny skies. Winds will be out of the south southwest at 5 to 15 mph.
Afternoon temperatures are expected to remain near 100° to start off the work week with a very slight chance for a stray shower Monday afternoon. As the upper-level ridge of high pressure strengthens over the Central and Southern Plains again, highs and the heat index values will likely increase. As we enter the end of July, conditions for Central Texas are usually the hottest of the year. It will be no different in 2017, with actual high temperatures potentially climbing into the lower and mid 100s! Heat index values may be near or exceed 110° as well heading into next weekend! Please make sure to limit your time outdoors and always drink plenty of water. An Excessive Heat Warning may be needed by the end of the week and into next weekend due to dangerous heat conditions!
