Be Prepared
It is important for you to know there is a threat of strong to severe thunderstorms for Central Texas this afternoon and evening. The entire area is under a MODERATE RISK for severe thunderstorms.
We have an extremely unstable airmass due to the flow off the Gulf. An upper level trough will push a cold front into the area beginning late this afternoon. Scattered showers and thunderstorms will develop rapidly by late this afternoon as the dry cool air encounters the warm moist air. We're looking at a time frame of 3 p.m. to 12 a.m. for the rapid development of thunderstorms.
The main threats will be from damaging thunderstorm winds, frequent lightning and large hail. However, due to the extreme instability in place, isolated tornadoes cannot be ruled out. I am not saying that we will have tornadoes. What I am saying is the potential exists.
Bottom line? Pay attention to the afternoon weather. Adam Krueger and Mary Wasson will be here to keep you fully informed if and when severe storms begin.
Morning lows:
Current temperatures:
Showers and thunderstorms should be approaching I-35 between 4:00 and 6:00. This looks to be a fairly fast-moving system to I would expect the rain to be out of the area no later than midnight.
Highs today will warm to the low 90s with a southerly wind 10 to 20 mph. Lows tomorrow morning will drop the upper 60s to low 70s.
After today, the overall weather pattern is going to find dry weather through the holiday weekend. Mornings will be warm and humid. Afternoon temperatures will peak in the 90s. The details can be found on your YNN 8 Day Forecast.

Pay attention to the changing weather later this afternoon. Be safe and have a good day.
