Turning Cooler into the Weekend

By Jay Grymes & Steve Caparotta

** The International Space Station (ISS) will make another “fly-by” appearance this evening -- the ISS’s visible track over WAFB Country will last roughly 6 minutes, beginning at about 6:50pm.  The path will start along the northwestern horizon and pass almost overhead as it heads towards the southeastern horizon. **

Highs made it up to around 70° for many WAFB neighborhoods under the sunshine and blue skies.  We’re expecting mainly fair skies through the evening and overnight with a dose of cooler air sliding into the lower Mississippi Valley.  That should allow Thursday morning lows to dip to around 40° for metro BR, with some WAFB communities north and east of the Capital City slipping into the 30°s for their Thursday morning sunrise.
So let’s cover the good news first: we’ll stay dry through the rest of the work week and the weekend.  In fact, between now and next Wednesday, we are currently calling for seven mainly dry days, with just a very slight chance of rain (20%) next Tuesday.

Plan on partly cloudy skies for Thursday afternoon with highs only reaching about 60°F.  And Thursday begins a run of cooler weather that will last through the weekend.  Lows for Friday morning will drop into the mid to upper 30°s for metro Baton Rouge, with highs topping out in the upper 50°s that afternoon.
As we go into the weekend, it will turn even cooler thanks to a reinforcing surge of Canadian air.  Highs for Saturday and Sunday may struggle to get to the low to mid 50°s.  In fact, we could be setting the stage for some of the coldest air this season. 
We mentioned last night that Baton Rouge/Metro Airport has recorded just 6 “freeze days” so far this winter, ranking 2nd among the fewest freezes for any winter (since 1930).  We did dip to 28° on December 30th, but have not slipped below 30° on any other day this winter season.  (At least not yet!)
At this point, we’re posting a Saturday morning Baton Rouge low just a tad above freezing (34°) with a light freeze (31°) for Sunday morning, plus a third chiller for Monday’s start (33°).  As you can see, just a degree or two could be all the difference between one, two or even three morning freezes for the ‘Red Stick.’  And many neighborhoods near, north and east of BR can expect a light freeze for all three mornings!
After a chilly weekend to open the month of March, the weather should start to warm  by Monday afternoon -- in fact, we’ve got highs climbing back to around 70° by next Tuesday. 
Yep -- say “Hello!” to Louisiana winter weather!
