Summer to winter within 24 hours


Record Heat Today ahead of STRONG cold front

Good Evening, Folks!
What a roller coaster ride this week has been so far. We approached the top of the roller coaster today with a new record high temperature of 99°F at Austin’s Camp Mabry beating the previous record of 97°F set back in 1926. Austin Bergstrom International Airport also crushed their previous record high of 93°F set back in 2014 by 4 degrees coming in at 97°F this afternoon.
Today’s summer-like heat is about to take a big drop for our Friday as an unseasonably strong cold front sweeps through the area early tomorrow morning. 

Current Temperatures across the southern Plains (as of 6:45 pm Thursday)


The leading edge of the colder air is currently approaching the I-20 corridor in northwest Texas and has prompted the Storm Prediction Center to issue a SEVERE THUNDERSTORM WATCH for portions of north and north central Texas, including the DFW Metroplex, until 1:00 AM CDT Friday. The biggest threats from the storms that develop in those areas this evening and early Friday morning will be scattered large hail and isolated very large hail events up to 2 inches in diameter along with scattered damaging winds gusts to 70 mph. By the time those storms reach central Texas early Friday morning, the storms should be below severe levels, but one or two strong storms cannot be ruled out (especially north and west of Austin).

Severe Thunderstorm Watch
Counties shaded in yellow on the map below are included in the SEVERE THUNDERSTORM WATCH until 1:00 AM CDT Friday…a watch means conditions are favorable for the development of severe weather…a warning means severe weather is imminent and/or occurring and that it is time to seek shelter



Cold Front Timeline
According to high resolution forecast model data, the front will be moving into the far northwestern Hill Country between midnight and 1 a.m. with showers and thunderstorms and moving into the Austin Metro Area between 3:30-4:30 a.m. Friday morning with gusty winds, scattered showers and thunderstorms and rapidly falling temperatures. By 7 a.m. the leading edge of the cold front will be south of San Antonio and pushing south southeast towards the extreme northwest portions of the Houston Metro Area. Rain may stick around behind the front through noon Friday. High temperatures Friday will occur early Friday morning and drop drastically behind the front into the 40s and 50s across the area. Afternoon highs on Friday will struggle to rebound into the mid to upper 50s in Austin with cloudy skies, rain showers (in the morning), and gusty north winds will make it feel like it’s in the 40s!
