Prepared by UT University/Incident Response Meteorologist Troy Kimmel
235pm CT – Tuesday / 26 May 2020
… Chances Increasing for Another Round of Severe Thunderstorms Tomorrow into Tomorrow Night …
… Threat of Large Hail, Damaging Straight Line Thunderstorm Wind and a Few Tornadoes …
A trough, or line, of upper level low pressure continues over the central USA. As a smaller low pressure disturbance.. moving east southeastward in the counter clockwise flow around this trough.. moves into our area by tomorrow afternoon into tomorrow night and times with maximum daytime heating, abundant low level moisture and more than adequate atmospheric instability, we’ll see the possibility of a few stronger, potentially severe, thunderstorms along the IH35 corridor.
In the day two severe thunderstorm outlook, the NWS/Storm Prediction Center originally posted for our area, a “marginal” to “slight” risk (levels 1, 2 of 5), then upgraded to a “enhanced” risk (level 3 of 5) at midday today for severe thunderstorms for our area tomorrow into tomorrow night; the main risks being mentioned include large hail, strong/damaging straight line thunderstorm wind and even a few tornadoes.
Dangerous lightning will also be a risk around any thunderstorms.

In addition to the severe thunderstorm threat, we could see some localized nuisance flooding problems as these thunderstorms move through our area. NWS/Weather Prediction Center forecast rainfall amounts are generally an 1 inch or less, so as long as we use common sense and remember to “turn around, don’t drown,” we should be in good shape.
