Warmer, Spotty Showers on Friday

By Jay Grymes & Steve Caparotta

Showers skirting the southwestern and south-central coastal parishes this afternoon are expected to remain there, and while we did see a few returns on Titan9 Doppler this afternoon, the fair skies for most neighborhoods were greatly appreciated. 
It looks like we’ll start out Friday with another round of partly-to-mostly cloudy skies and lows in the low to mid 50°s.  Plan on a sun/cloud mix for Friday afternoon, with highs in the low 80°s and increasing low-level moisture thanks to southeasterly winds.  We may see a few blips on Titan9 Doppler radar during Friday afternoon, but most stay dry through the day -- so we’ll give it a weather grade of “B” for downtown’s Live After Five.

The forecast for Saturday is looking a bit better than it did just a day ago.  We’re keeping a slight chance of rain in the Saturday afternoon forecast but dropping it to about 20% or so, compared to previous forecasts that were calling for rain chances of around 30% for Saturday afternoon and early evening.  We still expect a disturbance and an associated frontal system to develop to our north on Friday into Saturday, but it looks like the main energy remains to our north through Saturday evening.

While the Saturday outlook has improved a bit, not so for Sunday.  The system that will be to our north on Saturday will sag southward on Sunday, enhancing the likelihood of afternoon showers and t-storms.  We’re thinking a 50-50 chance of rain for your back yard for Sunday afternoon and evening.

Unfortunately, we don’t expect a significant cool-down following Sunday’s rains, nor are we anticipating a nice run of dry weather.  We’re keeping forecasted highs up around the 80° to 83° range for Monday and Tuesday, with rain chances both days in the 30% to 40% range.

The current extended guidance has our next front arriving in the Bayou State very late Wednesday or early Thursday, keeping our mid-week outlook very unsettled.  We should see some improvement by next Friday.
