The First Alert Forecast calls for a mild Saturday morning start under mainly clear skies with temperatures near 70 degrees at daybreak around metro Baton Rouge. Plan for partly cloudy skies to a sun/cloud mix into the afternoon, with rain chances running at 20% to 30% for the day.
So far, it’s been a quiet September morning throughout SE LA and SW MS – only limited activity on FIRST ALERT Doppler radar; and approaching late morning, temperatures are in the mid 80°s (with a “feels like” in the mid 90°s).
It’s a back-to-work, back-to-school Monday and in the world of weather, we’re back to more September heat! Mid 90°s were the rule this past weekend and it appears that trend will continue today – and, in fact, for the majority of the week ahead.
Rain will be hard to come by over the next several days as high pressure remains in control locally. An upper-level low is currently moving across the Gulf of Mexico and could provide a shower or two south of I-10 today.
The First Alert Forecast calls for a hot and mostly dry weekend ahead. Plan for mid 90s for many WAFB neighborhoods Saturday, followed by low to mid 90s Sunday. Rain chances Saturday are set at 10% or less, with the forecast Sunday calling for 20% or less.
Overall, another relatively pleasant morning in progress – for your Friday, there are no driving challenges (at least regarding weather); only a blimp or two on FIRST ALERT Doppler radar and temperatures generally in the low/mid 70°s.
Not many umbrellas will be required over the course of the next few days and starting with this morning, it’s a quiet scan on FIRST ALERT Doppler radar with only “limited” activity expected later today.
Upper 90s, summertime humidity, and abundant sunshine prompted the National Weather Service (NWS) to issue a Heat Advisory for most of the WAFB region Friday. Expect much the same Saturday and Sunday in terms of temperatures and humidity.
Portions of the local area will once again be under a Heat Advisory today. Be sure to take those heat related precautions seriously and stay hydrated, take frequent breaks, look before you lock, and check in on kids and the elderly.
A Heat Advisory is in effect from 10 a.m. this morning through 7 p.m. this evening. High temperatures will top out in the mid to upper 90°s, with peak heat index values between 105°-109° this afternoon.
A radio station received more than 2,000 distress messages, including reports of a 5-month-old baby stranded on a roof and a grandmother with six grandchildren who cut a hole in a roof to escape rising floodwaters.
Moisture associated with a broad low pressure system in the Gulf of Mexico will bring a chance for a few afternoon showers over the coming days. This low has a low end chance for tropical development, but the core is essentially moving away from SE LA.
Fair skies and sunshine with lower than average summer humidity typically means low to mid 90s for many WAFB neighborhoods, but the drier, less humid air is much appreciated and that looks to hold into Saturday as well.
Hurricane Dorian remains the main weather story for the Southeast United States. As of the 4 AM advisory by the National Hurricane Center Dorian remains a strong Category 2 Hurricane with sustained winds of 105 mph.
Scattered rains were the story Friday, yet the First Alert forecast gets even wetter Saturday and Sunday. Friday afternoon’s Storm Team forecast sets rain chances at 70% or better both Saturday and Sunday, with highs both days in the mid to upper 80s.
It’s a relatively quiet out-the-door on this back to work/back to school Monday morning. Only limited activity showing up on FIRST ALERT Doppler radar – at least for the time being – and that’s mainly along the coastal communities.
The good news – SE LA and SW MS *are not* under a Heat Advisory or an Excessive Heat Warning like we were yesterday! It’s still steamy out the door but at least we’re starting out below 80° - grab the umbrella today, it’s been awhile since the majority of us have needed it.
Heat has been the lead weather story through the last couple of days, and heat will be the main weather story this weekend. Don’t be surprised if additional Heat Advisories are issued for parts or all of the WAFB over the weekend.
The current weather pattern is not expected to change much in the coming days. We do expect a slightly earlier development for showers and t-storms Sunday and these storms will be a little bit more widespread.
Overall, our early August weather pattern isn’t expected to change much over the course of the next several days – starting with this morning, temperatures pretty typical for early morning this time of year – in the low to mid 70°s.
