TK’s Special Briefing…. (120pm CT-Fri/24Apr2015)

Austin / Travis County and South Central Texas Weather Update #7
Prepared by UT University/Incident Meteorologist Troy Kimmel

…. “Slight” Risk of Severe Thunderstorms Continues Through Tonight ….



Rain showers and thunderstorms.. according to the latest high resolution guidance..
will develop to our west during the course of the remainder of the afternoon.
The thunderstorms.. likely to develop in a broad north to south line.. will sweep
through theĀ  IH35 corridor in the evening to nighttime hours with severe thunderstorms
possible. At this time, the highest risk is for larger hail and damaging straight line
thunderstorm wind. The threat of tornadoes is lower.

Rainfall.. on average across the area.. will be in the 1/2 to 1 inch range with it being
beneficial in most areas. However, earlier today in counties south and east of the Austin
area and the IH35 corridor, some rainfall totals of 3 1/2 to 4 1/2 inches were observed.
In these areas, the additional rainfall later today into tonight will likely cause some
flooding issues.

Current guidance suggest that precipitation should end across the IH35 corridor by
1 to 2 am tomorrow morning with much drier westerly surface winds taking over the
area tomorrow with afternoon high temperatures approaching 90 degrees.

…. Another Severe Thunderstorm Threat Late Sunday into Monday ….

A strong low pressure area and cold front will pass over the area around the time of
the Monday morning rush hour. Moisture will increase again Sunday ahead of this
system. The NWS/Storm Prediction Center, accordingly, has our area in a “slight”
severe thunderstorm risk area Sunday night into early Monday. Drier and much
cooler will filter into the area in the wake of the system Monday mid morning into
Tuesday.

I’m continuing to monitor..
