More Heat & Humidity!

We continue to reach the 90°s for highs, and a second morning with lows in the 70°s for many WAFB neighborhoods is a good reflection of the low-level humidity that has set-up across the viewing area. Yes, hot and humid indeed.

We’re not expecting any significant changes for Wednesday either. Look for sunrise temps in the 70°s for the Capital City with afternoon highs climbing into the low 90°s -- the 11th straight day in the 90°s. We do add a couple of afternoon t-showers to the Wednesday forecast, but we’re going with rain chances at a modest 20%, so most of us stay just hot and dry.

Rain chances go up ever so slightly for Thursday, with better rain chances on Friday. We think we may end our run of 90° days on Thursday or Friday as well. A late-spring cool front will slip into the Bayou State late Thursday in to Friday, prompting us to post a 30% rain chance for Friday. In other words, some of us get rain, but unfortunately many of us will stay essentially rain-free through the coming days. And to be honest, even for those that do get rain over the next three days probably won’t get what they would like: right now the NWS Hydrometeorological Prediction Center has most of the WAFB region getting less than one-half-inch of rain between now and the weekend.

Yep -- with our two-week run of dry and warmer-than-normal weather, we seem to be easing back towards near-drought conditions.

There is one piece of good news: Friday’s cool front will give us a reasonably good Saturday for outdoor weather. The “drier” air mass behind Friday’s front will mean morning lows on Saturday dipping well into the 60°s and a less-humid afternoon, although it will be warm given the expected clear skies and sunshine. But the spell of low-humidity will be very brief -- in fact, we think it’s gone by Sunday!

Better rain chances are currently posted for the extended outlook on Monday and Tuesday.

And in the tropics, T.D. Beryl continues to display a reasonably good satellite presentation and symmetry, with “productive” rainbands. NWS Doppler radar estimates show that Beryl may have dumped more than 10” of rain over a section of northern Florida and as much as 6” to 8” over parts of extreme SE Georgia, but thus far, the rains do not appear to be generating widespread flooding. Beryl is moving to the northeast and is expected to continue along this track across eastern Georgia than along the Carolina coasts and emerge in the Atlantic, where ‘she’ could regain tropical-storm strength before reaching the cooler Atlantic waters and losing ‘her’ tropical characteristics.
