The Heat Continues With Another Heat Advisory And A Few Storms Today

...Heat Advisory Until 7 PM...

Short Term Forecast:  Once again it is a very warm and muggy morning across Southeast Louisiana.  We have some clouds with temperatures in the mid to upper 70s.


The ridge of high pressure that has been sitting over us the last few days will start to break down and moves to the west today.  This will allow for some extra Gulf Moisture to stream up over Louisiana.  That will help us to get a slightly better chance of seeing some rain today.  I'm only expecting a few storms (20% chance) at best, but that is better than we've had all week.  Therefore, we will be partly cloudy and very hot with those isolated storms.  High temperatures will remain in the mid 90s.  The heat index will be around 105°.  The NWS will continue the Heat Advisory until 7 PM today due to the oppressive heat and only a few storms.

Any rain that pops-up will dissipate by 10 PM and then we will be left with partly cloudy skies overnight.  Low temperatures will be in the mid to upper 70s.

The weather will really start to change on Friday.  An upper-level low will move across Florida and into the Northern Gulf of Mexico.  This low will track west toward Louisiana, and it will send some deep tropical moisture over us.  That will allow for scattered showers and thunderstorms to form over Baton Rouge during the day.  Some of the rain could be heavy at times.  High temperatures will still make it into the mid 90s before the rain starts.  Friday Night will be mostly cloudy with a few lingering showers.  Lows will fall to the mid 70s.

Weekend Outlook:  The upper-level low will continue to move to the west this weekend.  We will be on the backside of it, so it will still bring the tropical moisture over Baton Rouge.  Saturday and Sunday will have partly cloudy skies with scattered showers and thunderstorms in the afternoon/evening hours.  Highs will be in the lower to mid 90s and lows in the lower to mid 70s.

Tropical Outlook:  A weak area of low pressure is producing a small area of clouds and showers over the SE Caribbean Sea.  Conditions are not favorable for development as the low moves to the west at 10 to 15 mph.  NHC is giving this a low chance for development.


I'm also tracking the upper-level low/tropical wave that will move across Florida today.  It is not expected to develop into anything at this time.

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

Once again be sure to try and stay cool.  Have a great day! -Dave

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 up!

Week Ahead:  The area of high pressure will stay put through Wednesday. …

Major Snowstorm Headed To Northeast US Tomorrow

For all of my friends and family that live in the Northeast US...here is my latest analysis of the winter storm heading your way on Friday into Saturday:

The same area of low pressure that brought the heavy rain and thunderstorms to Louisiana last night and this morning will be moving up the East Coast on Friday.  It will get much stronger and become a  Nor' Easter that will impact all the major cities from Philly to NYC to Boston as well as inland areas.

Delmarva to NJ Coastal Areas:  Winter Storm Warning in effect from Friday AM until Saturday AM!  It looks like it will start out as a brief period of snow along the coast in the morning then change into a windy rain during the day.  Then go to a heavy snow late Friday into Saturday Morning.  Snow accumulations of 4-8" are possible.  Some minor ice accumulations are possible too. Winds will be sustained around 30+ mph and coastal erosion will be possible too.

NE PA: Winter Storm Warning from 10 am Friday until 7 am Saturday! …

Deadliest and Strongest Tornadoes In Louisiana History

If you are wondering what is the deadliest tornado ever to hit in the Baton Rouge area...it was back on April 24, 1908 in Amite, LA to Purvis, MS.  (Grazulis, Thomas P. (1993). Significant Tornadoes 1680-1991: A Chronology and Analysis of Events. Environmental Films)  143 people lost their lives.  This was part of the 1908 Dixie Tornado Outbreak.  The storm started around 11:45 AM near Weiss, LA in Livingston Parish and tracked toward St. Helena Parish.  2 people were killed in Denham Springs and 2 in Montpelier.   Then it tracked toward Amite, LA where a path of damage was around 2 miles wide.  29 people were killed there.  It then traveled on the ground to Purvis, MS where the greatest damage was and most of the lives were lost.  The damage path was around 155 miles long.  


The F-Scale and  EF-Scale didn't exist then, so it was not given a rating at the time.  However, using recent technology and assessments, the storm would have been given an F-4 or EF-4 rating.
