More Heat With Scattered Storms Today

Short Term Forecast:  We have a very warm and muggy Wednesday Morning across Baton Rouge with partly to mostly cloudy skies.  Temperatures are in the mid to upper 70s.

Look for another afternoon similar to the last few with plenty of heat and thunderstorms.  Baton Rouge is sitting between to areas of high pressure - one over the Four Corners of the U.S. and another off the East Coast.  This is allowing deep tropical moisture to come right up the Gulf into the state.  Combine that with daytime heating plus the sea breeze and you get scattered showers and thunderstorms.  Some heavy rain will still be possible too.  High temperatures will be in the lower 90s.  The heat index will be around 100.

The showers and storms will continue into the evening hours and then they will taper off overnight with partly cloudy skies.  It will be stuffy with lows in the mid 70s.

Rest of the Week:  A trough of low pressure will move down the Eastern U.S. on Thursday and Friday.  This will send a weak cold front toward Louisiana and that will help to set off more scattered showers and storms both days.  It looks like the front will stall along I-10 before drifting to the Coast by late on Friday.  Highs will be in the lower 90s both days.  Low temperatures will be in the mid 70s Thursday Night, but fall to the lower 70s Friday Night.

Weekend Outlook:  Some slightly drier air will filter down to Louisiana on Saturday, but it will not last long.  We will be partly cloudy and slightly less humid with spotty afternoon showers.  Highs will be in the lower 90s and lows in the lower 70s.

A tropical wave/TUTT low, which is currently stalled along the Florida East Coast, will move into the Gulf of Mexico this weekend and merge with the southern-half of the trough.  Together, these systems will move to the west and help to set off scattered showers and storms over Baton Rouge on Sunday.  It will stay hot with highs in the lower 90s and lows in the lower 70s.

Tropical Outlook:  Tropical Storm Chantal is poorly organized today.  It is really moving too fast for it to really develop well since it is racing WNW at 29 mph.  Winds are down to 45 mph and the pressure is up to 1011 mb.  The latest satellite imagery shows that the storm may weaken into a depression or even a tropical wave later today as it approaches Hispaniola.  Due to the weakened nature of it, it will also move more to the west before turning north.  Now it will likely track across Eastern Cuba and cross over Central Cuba as it moves north toward the Florida East Coast by the weekend.  Then a final landfall could be over the Georgia Coast early next week.  Needless to say, we will have to keep an eye on the system to see how it moves and tracks.

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

Stay dry and have a nice day!

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 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 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.
