Very deep closed low is dropping south of the New Mexico-Arizona border. It's progged to lift out tonight and have a dry slot punch in from Del Rio to San Angelo. Severe storms are supposed to fire along the dry line today. Big negatives are widespread overnight convection -flooding has occurred. I-35 is closed near Temple.. At the top of the upper low, I've looked at SW Kansas and believe its too cold up there -only a squall line there is forecasted. There is always the chance of a rogue storm ahead of the line. Target is San Angelo.
