PM Update: A few showers tonight, warm with a storm possible tomorrow

We’re settling into this warm stretch nicely with what should be the first of many days near or above 70 in the coming week. Clouds are beginning to roll in from the west, and that often means a cold front with cooler air is on the way. Well, a cold front will arrive tomorrow but chilly air is going to remain quite hard to find for a long while.

Through Tonight: Clouds increase the rest of the afternoon, and it’s mostly cloudy by evening. Between midnight (well west) and about 8 a.m. (south and east), a broken line of showers may move through. These look spotty to scattered and should not produce a lot of rain. Temperatures bottom out in the low-and-mid 50s.

Tomorrow (Tuesday): After a slight risk of early a.m. showers, skies should trend to at least partly if not mostly sunny. A southwest wind around 10 to 15 mph will help boost temperatures into the mid-and-upper 70s. Someone hits 80? We’ll see! There’s a risk of a late-day thunderstorm, though the odds are not super high and if they pop they’re likely to be isolated to scattered. But anything that fires could be strong.

Louisiana deluge: Parts of south central Louisiana have been pummeled by rain today with near-stationary storms. A flash flood emergency remains in effect until at least 6:30 p.m. eastern time for Lafayette, St. Landy and St. Martin parishes. As much as 8-15” of rain or more has fallen in these locations since this morning, and rain continues across the area this afternoon.

Pollen update: Susan Kosisky from the U.S. Army Centralized Allergen Extract Lab writes, “Trees are in the MODERATE range at 32.91 gr/cubic meter, grass pollen is LOW at 0.32 gr/cubic meter and mold spores are in the LOW range at 631.47 spores/cubic meter.”
