Turning Cooler on Saturday

By Jay Grymes & Steve Caparotta

** Minor flooding continues along portions of the Amite and lower Tangipahoa, but conditions will improve through the weekend.  Go to and click on the “River Stages” link for details. **
We’ve enjoyed back-to-back (Thursday & Friday) sunny afternoons, a welcomed change after our run of wet weather.
A dry front is sliding south through our viewing area this afternoon.  It’s hardly generating any increase in cloud cover, but you may have noticed the “dry” northwest winds.  Later this evening, you’ll note some additional clouds moving in and we’ll go to mostly-cloudy or even cloudy skies overnight.  A few may even get a light sprinkle overnight, but little accumulation.  The overnight clouds are courtesy of a follow-up trough moving south through the region.  We’ve seen some rain over the northern half of the state thanks to this trough, but we’re thinking that the rain area will shrink as it heads towards us later tonight.  Behind the trough, a cooler air mass will take control, and the clouds won’t stay long: skies will begin clearing early Saturday, with a sunrise temps around 40° for the ‘Red Stick.’

Plan on sunny skies for Saturday, but it will be breezy -- occasionally downright windy -- and noticeably cooler with afternoon highs struggling to make the mid 50°s for some WAFB neighborhoods.
That cold, dry continental air mass will allow temps to fall to near freezing for Sunday morning!  But winds quickly swing around from the south on Sunday under mainly sunny skies, allowing for temps to rebound into the 60°s for Sunday afternoon.
Our next rain-maker will be associated with a low-pressure system over the Southern Plains which will remain to our north, but drag a cold front through our viewing area late Monday into the pre-dawn hours of Tuesday.  Another storm system will deliver a cold front with rains and storms late Thursday.

And while we offer these “extra-extended” forecasts with a word of caution, the outlook for NEXT weekend may be shaping up to be rather wet.
We made mention of it yesterday, but it's worth one more look at "this date in weather history" today. The biggest snowfall for many locations around south Louisiana occurred on Feb. 14-15, 1895. Can you imagine 2 FEET of snow on the ground? That's what was reported in Rayne! The logs from back then show over a foot in Baton Rouge...with the highest reported total along the Gulf Coast an amazing 30 inches in Beaumont, Texas!
