While we’ve enjoyed a bit of a lull in the heavy precipitation this evening, it’s expected to pick up again overnight as a piece of upper level energy pushes into the area and interacts with a nearly stationary cold front currently located along a line from San Angelo to Goldthwaite to Gainesville. A lively 35 to 40 knot nocturnal low level jet (a fast moving layer of air approximately 5,000 feet or so above the ground) will help feed additional gulf moisture into the area which will aid convection during the overnight hours. Flash Flood Watches are in effect for numerous counties across western north Texas and down into the Big Country/Concho Valley area until mid-day tomorrow with an additional 1-2 inches expected with some isolated higher totals mixed in. Severe weather is not expected, but a few storms could become strong with gusty winds and lightning as the main threats overnight. The rain and storms that develops overnight will be training to the over the same areas repeatedly making localized flash flooding a concern.
Here’s the latest look at simulated radar for the late evening and overnight hours. As always, keep in mind it’s just what the computer thinks will happen, but so far this model has been pretty accurate with this system. Since it’s animated, give it a few seconds to load. After this rain event, we dry out and high pressure returns for the remainder of the week and into the weekend.
