5/13 – Trey Tonnessen’s “Enhanced Severe Risk” Monday Evening Forecast

Meteorologist Trey Tonnessen

The developing squall line over southwest Louisiana has already had a history of producing a few tornadoes and widespread wind damage. This line is expected to accelerate some, moving into the viewing area between 8 and 9, then across most of the area after midnight. A flood watch remains in effect for areas along and south of the I-10/12 corridor due to the threat for heavy rainfall that could result in localized flash flooding primarily in urban and poor drainage areas. An enhanced risk for severe weather remains primarily along and south of the I-10/12 corridor for the threat of a secondary round of storms moving into the area this evening with damaging winds and hail being the primary threat, but a tornado cannot be ruled out. The morning convection has surged southeast into the coastal waters putting down a decent cold pool that has moderated temperatures and stabilized the air mass overhead for now.

As always: A cloudy day is no match for a sunny disposition. Be nice to each other.
