More Heat Today, A Cold Front Friday Night And The Tropics Are Active

Short Term Forecast:  We have a pretty warm and muggy Thursday Morning with mostly clear skies and temperatures in the 70s.

The ridge of high pressure that has been sitting over us the last few days will build to the west today.  This will keep us mainly dry and hot with partly cloudy skies.  A few showers are possible, but I'm not expecting many of you to see rain.  High temperatures will be in the lower to mid 90s.

A few clouds will linger over the city tonight and it will stay warm.  Low temperatures will be in the lower 70s.

The weather will start to change a little on Friday.  A trough of low pressure in the upper-levels of the atmosphere will move down along the Eastern U.S.  This will send a cold front toward and through Baton Rouge.  The front will arrive late in the day and it will help to set off a few showers.  Therefore, we will be partly cloudy and hot with a few showers.  Highs will be in the lower 90s.  Friday night will be partly to mostly cloudy with a few showers as the cold front stalls along the Louisiana Coast.  Lows will be in the lower 70s.

Weekend Outlook:  The front will continue to stall along our coast.  At the same time, an area of low pressure will be moving across the Bay of Campeche.  This low will send some tropical moisture toward Louisiana all weekend and that will help to set off a few showers.  Saturday and Sunday will both be partly cloudy with isolated showers and a few storms.  Highs will be in the lower 90s and lows in the lower 70s each day.

Tropical Outlook:  Gabrielle is now a tropical depression.  It is located about 190 miles WNW of Bermuda with 35 mph winds.  The pressure is 1010 mb.  The depression will move to the NNE over the next few days toward Nova Scotia.  It may become a tropical storm again, but it will stay out at sea.

Hurricane Humberto continues to be well organized as it sits around 440 miles NW of the Cape Verde Islands.  Winds are 85 mph and the pressure is 982 mb.  It is moving to the N at 14 mph and will turn to the NNW to WNW over the next few days as it moves out to sea.  It is also forecast to weaken over the cooler waters.

Lastly, I'm watching an area of low pressure (Invest 93L) located over the Yucatan Peninsula.  It will emerge into the Bay of Campeche later today or tonight. As long as it remains over water, there is a chance this low could form into a tropical depression by the weekend.  The forecast models show it moving to the west and into Mexico.  However, some moisture could stream north toward Louisiana early next week from this system.  This would increase the chance of rain over Baton Rouge, but we would not be directly impacted by this system.

Elsewhere...there is a broad area of low pressure located 550 miles east of the Leeward Islands.  Conditions could become somewhat favorable for development over the next few days as it moves to the west and northwest.  NHC is giving it a low chance of becoming a tropical cyclone during the next 5 days.

Have a great day and stay cool in this heat! -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 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.
