What a difference a day makes!

By Jay Grymes & Steve Caparotta

As expected, most of the rains had exited the WAFB viewing area before lunchtime, but the rains made for a ticklish morning commute in some areas. Most WAFB neighborhoods received between 0.25” and 1.00” over the two-day stretch -- much appreciated by many, but most communities are still drier-than-normal for this time of year.

We’re done with the rain for the rest of the week, and our extended forecast has only spotty showers in the weekend forecast.

Tuesday (today) was an “upside down” day from a temperature perspective. The clouds were more persistent into the afternoon than Jay had expected and that kept temps for showing any significant rebound after the morning frontal passage. The day’s high temp occurred before dawn and just prior to the arrival of the morning rains. By 10AM, Baton Rouge temps dropped into the 50°s and stayed there through the afternoon.

Skies clear tonight and with winds back down as high pressure settles over the mid-Mississippi Valley. That should allow Wednesday morning lows to drop into the upper 30°s for many WAFB neighborhoods, especially those north of the I-10/12 corridor. Sunny skies will be the story for Wednesday, with afternoon temps rebounding into the low to mid 60°s for the Capital City. 

Look for morning minimums to again drop into the 30°s around metro BR on Thursday, with highs on Thursday afternoon climbing to near 70° under sunny skies. And by Thursday, with the regional high shifting farther to the east, we’ll be set-up for Gulf “return flow,” bringing a return of milder air along with a rapid rebound in low-level moisture.

Our forecast for Friday, Saturday and Sunday reads “warmer than normal” for all three days, with highs in the 70°s -- possibly even the upper 70°s by Sunday. With the in-flow Gulf moisture over the period, we can’t entirely rule out a shower or two, but at least for now we’re only posting rain chances at about 10% for Saturday and Sunday. So go ahead and make plans to do something outdoors in the mild “October-like” weather!
