Today (Fourth of July): We’ve got a slight risk of remnant morning showers or a rumble. After that, it’s a new day, a holiday even, but with the same old story of heat, a lot of humidity and 30-40% chance of afternoon/evening thunderstorms. Not everyone will see their late-day July 4th activities interrrupted by a storm, but it’s a scenario to certainly keep in mind. And while storm chances may not be overwhelming, any storms that do develop could be intense with severe winds and large hail. Before that, highs should reach the upper 90s under partly to mostly sunny skies and the heat index topping out near 100-105. Confidence: Medium

What is the Storm Threat Level?

Tonight: Evening thunderstorm chances remain around 30-40% before diminishing overnight. There’s little relief from the heat as lows hold up in the 70s to near 80 under partly cloudy skies. Confidence: Medium

Tomorrow (Thursday): The humidity holds its ground and the heat is even a bit more potent on Thursday. Highs shoot up to the upper 90s or near 100 and that heat index makes a run at 105 or a touch higher. Mostly sunny skies are of no help to those trying to hide from the heat. Just a slight chance of an afternoon storm. Confidence: Medium-High

Tomorrow night: Nothin’ new here.... just alight chance of an evening storm. Otherwise it’s partly cloudy and very warm once again as lows only get down to the 70s to near 80. Confidence: Medium-High


The forecasst for Friday, Saturday and Sunday is mainly a cut-and-paste one. The hot and humid pattern remains entrenched with partly to mostly sunny skies, highs in the mid-to-upper 90s, afternoon heat indices topping 100, and nighttime lows in the 70s to near 80. Probably nothing more than an isolated storm Friday and Saturday, with a little better chance on Sunday. Confidence: Medium
