An area of low pressure moving eastward through the area late last night and this morning produced widespread rain totals of 1" to 2" around the area, with isolated spots approaching 3"! It was nice to see some sunshine return this afternoon!
The rains moved out early this morning and the fog wasn’t as widespread as we feared, so the morning commute wasn’t as bad as it might have been. While the rains exited early in the day, the clouds were a bit slower to exit. However, bright sunshine had returned to most areas by late this afternoon.
It looks like the clouds will return overnight, accompanied by another round of developing fog after midnight. The overnight clouds will be aided by another weak cool front that slides through the lower Mississippi Valley tonight and early tomorrow and while we can't rule out a stray sprinkle or shower, most of us should remain dry on Friday.
The air will turn slightly cooler and “drier” (less humid) behind Friday morning’s frontal passage. Still, the clouds won’t completely clear the region, so we’ll go with a mix of sun and clouds for Friday afternoon with highs in the low 70°s. Yes, the weather for Friday evening’s Southdowns Parade should be fine with temps in the 60°s.
We may awaken to another round of patchy morning fog on Saturday, but the weather should be fine for the Spanish Town Parade: sunrise temps in the upper 40°s to around 50° for the ‘Red Stick’ with afternoon temps climbing to about 70° under another afternoon with a sun/cloud mix.
If you’re hoping for some good outdoor time this weekend, we recommend you make plans to get it done on Saturday. Sunday looks “wet” and the forecast stays with “rain likely” for both Monday (Lundi Gras) and Fat Tuesday (Mardi Gras).
By Sunday, surface low pressure over the U.S. Plains will be headed towards the Great Lakes, with its trailing cold front tracking towards the lower Mississippi Valley. That front will be over the state by early Monday, potentially setting the stage for a round of active weather -- we’ll have to keep a watch on these developments over the next couple of days.
Our current guidance indicates that Monday’s front will then slow and stall along or near the coast, serving as a focus for rains throughout Monday and Tuesday - - not great news for Baton Rouge or the Crescent City as we end the Mardi Gras season. The wet weather should be out of the area by the morning or mid-day Wednesday.
