Today Will Be Cool, But Much Warmer Weather Arrives On Wednesday

Short Term Forecast:  We have a mostly clear start to this Tuesday across Southeast Louisiana with a few high clouds overhead.  It is much cooler with temperatures in the upper 40s.


More high clouds will stream over us today as a mid-level disturbance moves from Texas across Louisiana.  This will give us partly cloudy to mostly cloudy skies at times.  An area of high pressure is also sitting over the Southeast U.S.  This is drawing in northeast winds and that will help to keep it much cooler this afternoon with high temperatures in the upper 60s.

The clouds will exit the area tonight and it will become mostly clear.  We will turn MUCH COLDER with low temperatures falling to the lower 40s.  Brrr!  Bundle up tomorrow morning!

Week Ahead:  The area of high pressure will move east of Louisiana on Wednesday.  This will shift the winds from the northeast to the south and we will start to warm up as Gulf Moisture streams inland.  This will give us partly cloudy skies and more humid conditions.  Highs will be in the mid 70s and lows will be much warmer as they only fall to near 60.


A few disturbances will move in from the west on Thursday and Friday along with a warm front moving up from the Gulf of Mexico.  The warm front will will tap into the Gulf Moisture and set off scattered showers each day.  At the same time, a cold front will also be headed toward Louisiana.  This will aid in developing even more rain for Friday and Friday Night.  Highs will be in the mid to upper 70s.  Lows in the mid 60s Thursday Night, but will be in the mid 50s on Friday Night.

Weekend Outlook:  The cold front will move through Baton Rouge by Saturday Afternoon.  This will put an end to the rain and we will become partly cloudy late.  It will turn MUCH COOLER with highs around 60.  Saturday Night will be mostly clear and CHILLY with lows will be near 40.

An area of high pressure will build over the Deep South on Sunday.  This will give us northerly winds and sunny skies.  We will have a very cool day with high temperatures only in the upper 50s.  Sunday Night will be clear and VERY COLD!  Lows will be in the lower to mid 30s!

Tropical Outlook:  Subtropical Storm Melissa formed yesterday in the middle of the Atlantic Ocean, or about 605 miles east of Bermuda.  Winds are sustained at 65 mph and it could get a little stronger in the next 24-36 hour.  Then it is forecast to weaken and lose its tropical characteristics.  Pressure is 982 mb.  It is forecast to stay out at sea, but become a true tropical system later today/tonight.  Right now, it doesn't have a totally warm core to it, and it is more like an area of low pressure associated with a cold front.  As it transitions to a warm-cored system it will become tropical in nature.


Elsewhere...the rest of the tropics are quiet.

You may want a light jacket today.  Have a good one! -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.
