Better Chance For Rain and Storms This Week

Short Term Forecast:  This Labor Day is starting off with a very warm and muggy morning.  Temperatures are in the mid to upper 70s under mostly clear skies.

We will have a hot and more humid afternoon across the Baton Rouge area as the eastern edge of a ridge of high pressure moves closer to Louisiana.  At the same time, another area of high pressure in the Gulf of Mexico will move to the east, and this will start to pump in Gulf Moisture over Louisiana.  This will give us partly cloudy skies with spotty showers and storms today.  However, it will not be enough rain to cancel any Labor Day plans you might have.  High temperatures will be in the lower to mid 90s.


Any rain that forms will dissipate by 9 PM and then we will be left with some lingering clouds overnight.  It will stay warm and muggy with lows in the mid 70s.

Week Ahead:  The eastern edge of the ridge will move over Louisiana on Tuesday and that will allow for a cold front to move closer to us from the north.  We will have plenty of Gulf Moisture over us too.  You can expect partly cloudy skies with isolated showers and storms.  Highs will be in the lower 90s.  Tuesday Night will be partly cloudy and steamy with lows in the mid 70s.


The cold front will get to Baton Rouge on Wednesday and stall over us through Thursday.  We will have scattered showers and storms on Wednesday, but more isolated storms on Thursday. Highs will be in the lower 90s before the rain starts.  Lows will be in the lower 70s each night.

The front will dissipate over us on Friday.  However, there will be just enough energy in it to set off a few afternoon thunderstorms.  Highs will be in the lower 90s and lows in the lower 70s on Friday Night with partly cloudy skies.

Weekend Outlook:  We will return to a more typically Summer-time weather pattern on Saturday and Sunday.  That means we will have partly cloudy skies with isolated pop-up afternoon showers and storms.  It will be hot and humid with highs in the lower 90s and lows in the lower 70s each day.

Tropical Outlook:  I'm watching a weak tropical wave located over the NW Caribbean.  It will move over the Yucatan Peninsula today and into the Bay of Campeche on Tuesday.  Some development is possible starting on Tuesday through the end of the week as it moves over the warm waters.  NHC is giving it a low chance of development over the next 5 days.  I'll keep an eye on it since it will be in the Gulf, but it looks like it will track to the west and stay south of Louisiana.

I'm also watching an elongated area of low pressure (Invest 97L) stretching from the Eastern Caribbean across the Lesser Antilles and into the Atlantic Ocean.  Upper-level winds are favorable for development, but there is a lot of dry air around the disturbance, and that would prevent it from developing.  NHC is giving it a medium chance for development in the next 2 to 5 days as it moves to the WNW at 10 mph.  It will track over the Caribbean to Hispaniola and Cuba over the next few days.


There are a few more tropical waves coming off of Africa that I'm watching too, and they could possibly develop into something over the next 2 weeks.

Elsewhere...the rest of the tropics are quiet and they will stay that way through Tuesday.

I hope you have a nice Labor Day and stay cool! -Dave

Comparison between Hurricane Matthew's possible forecast track loop vs Hurricane Betsy's

Some of you have been calling to say that Matthew's forecast to do a loop in the Atlantic Ocean off the SE U.S. is the same as what Hurricane Betsy did back in 1965. Well...that is not true. Betsy formed on August 27, 1965 just off the Leeward Islands. It quickly became a tropical storm on the same day, and then became a hurricane on August 29.  It made a few loops in its track with one north of Puerto Rico and a second north of the Bahamas.  There is a strong area of high pressure that was preventing Betsy from moving to the north, and that is what caused it to loop.  After the second loop, it then moved SW across the Bahamas, then turned west to move over far South Florida and then into the Gulf.  It eventually turned to the NW and quickly tracked right to New Orleans where it made landfall as a major hurricane on September 9th. Hurricane Matthew formed in the Atlantic east of the Leeward Islands as a tropical storm on September 28. It quickly moved west into t...

Flash Flood Watch now until Thursday Evening for WBRZ Viewing Area

The NWS in Slidell, LA has issued a  Flash Flood Watch for all of the WBRZ Viewing Area starting now and continuing until Thursday Evening. Rain has been falling for the last few hours and we have already picked up over 1.30" in Baton Rouge.  This is WAY more than the forecast models were predicting for this time.  The area of low pressure continues to develop over South Texas and a warm front will move up from the Gulf of Mexico by Wednesday Morning.  This will spread widespread rain and a few thunderstorms over Southern Louisiana all night and into Wednesday.  Then it looks like we will taper off the rain to just scattered showers during the day on Wednesday. On Wednesday Night, a cold front will move out of Texas into Louisiana.  As this happens, a squall line of thunderstorms is expected to move ahead of it and through Baton Rouge on Thursday Morning.  Some of these storms could be strong to severe with damaging winds and a few tornadoes. ...

The Unseasonably Cool Weather Continues

Short Term Forecast :  It is a very cold morning across the Capital City with clear skies and temperatures in the 30s.  A light freeze is expected!  I hope that you brought in your plants last night.  Take that jacket with you this morning. An area of high pressure remains over the Southeast U.S. today.  This will keep us sunny and with the northwest winds over us, we will stay cool.  High temperatures will be in the upper 50s. Another freeze is expected tonight for the Baton Rouge area.  We will be clear with calm winds and very good radiational cooling.  Low temperatures will fall into the upper 20s to lower 30s.  The NWS has issued a Freeze Warning for areas along and north of the I-10/12 corridor from 2 AM to 8 AM Wednesday Morning.  The freeze could last 2 to 6+ hours and that would be long enough to kill any vegetation.  Make sure you bring in your plants or at least cover them tonight!  Bundle ...
