…. Severe Thunderstorm Risk Saturday into Sunday for IH35 Corridor ….

A series of upper level low pressure disturbances will move across Texas and the southern
plains states beginning late tonight through tomorrow (Saturday) and into early Sunday.
In the wake of the last upper air disturbance, a weak surface cold front will move eastward
across our area later Sunday into Sunday night.

In advance of the approaching system, a warm front will be lifting back northward over the
area later today with a return south southeasterly surface wind and the return of abundant
low level moisture from the Gulf of Mexico. As the disturbance(s) approach, we’ll see an
increasingly unstable atmosphere combine with dynamic atmospheric lift to produce widespread
rain showers and thunderstorms late tonight (after 11pm) into tomorrow.. some of the
thunderstorms may be severe with the main risks being larger hail and damaging straight line
thunderstorms wind along with a slim risk of tornadoes mainly in areas northeast of the
Austin metro area.

Rainfall amounts.. over the upcoming weekend.. will average one to two inches with isolated
heavier totals mainly east of the IH35 corridor.

The threat of stronger thunderstorms (along with rainfall probabilities overall) will diminish
in the wake of the second disturbance early Sunday morning.

Please be weather aware as we head into the weekend. Please have at least two methods of getting severe weather information including the NWS/Austin-San Antonio website… weather.gov/ewx. Here is a useful link (courtesy Iowa State University) to the latest 20 special/severe weather text products from NWS Austin-San Antonio (with the latest product on top.. make sure to check the time of the latest product since it may have expired).

In addition, please make sure your NOAA/National Weather Service All Hazards Weather Radio is powered up and has a fresh set of batteries and is set to alarm in case the NWS issues watches and warnings.

I will continue to monitor this weather situation.
