And for yet another day, some fairly strong t-storms rocked parts of the viewing area.  Unlike last night’s late-night storms and the action last Tuesday and Wednesday, these storms were not out of the north and northeast.  However, they were still quite energetic and lightning-laden, fueled by our very most and unstable Gulf air.  What’s more, they got an additional boost from a pair of features working together: a sea-breeze-like wave heading inland and what appears to be a broad-but-weak non-tropical disturbance moving to the west-northwest over the western Gulf.

Bottom line: a very active middle of the afternoon for metro Baton Rouge and western Livingston Parish, sections of the Felicianas and points west including parts of Pointe Coupee, Avoyelles and St. Landry parishes.  Once again, the most noteworthy aspect of these storms was the lightning - - which is credited with power outages and even one or more fires.  But we can’t ignore the reports of small hail from WAFB viewers as well as locally-heavy downpours that produced more rounds of street flooding.

The action will wind down into the evening and most of us will stay dry through the overnight and early morning hours on Wednesday.  We could see a few showers down near the coast for Wednesday’s sunrise, but the morning commute for metro BR should be a dry one for just about everyone.  Plan for a muggy, partly-to-mostly cloudy start to Wednesday with morning temperatures in the mid 70°s.

For Wednesday afternoon, here they come again: 50% rain chance with highs getting up to around 90° before the rains arrive. 

The weather gets much quieter for Thursday and Friday, with rain chances for both days currently posted at 20% or less.  Both days start off in the mid 70°s for the Red Stick and afternoon highs reach the low 90°s for most, with a few neighborhoods potentially sneaking into the mid 90°s.

And into the Fourth of July weekend, we return to something fairly typical for this time of year: morning starts in the low to mid 70°s for the metro area, afternoon highs in the low 90°s, and scattered mainly-afternoon t-showers for both days.
