Spotty Storms Return Today and The Tropics Are Active

Short Term Forecast:  It is a warm and muggy start to this Tuesday.  We have mostly clear skies with some patchy fog and temperatures are in the 70s.

We will have another hot afternoon as a ridge of high pressure builds toward Louisiana from the west.  At the same time, a weak disturbance will move along the eastern-edge of the ridge, or right over Louisiana.  Moisture will be increasing a little more today as well.  This means we will be partly cloudy with spotty to isolated showers and thunderstorms.  Not all of you will see the rain, but there is a higher chance of rain today verses yesterday.  High temperatures will be in the lower 90s.

Any rain will dissipate by 9 PM and then we will be left with some lingering clouds.  It will be a warm and muggy night with lows in the lower 70s.

Week Ahead:  The ridge of high pressure will build over the Deep South on Wednesday, but it will start to retreat back to the west on Thursday and Friday.  What does this mean for our weather?  We will be partly cloudy with only a slight chance of a shower Wednesday through Friday.  It will be hot and humid with highs in the lower 90s and lows in the lower 70s each day and night.

Weekend Outlook:  The ridge will continue to build back to the west this weekend.  At the same time, a trough of low pressure will set up along the East Coast.  This will send a weak cold front into the Deep South, but it will not impact our weather very much.  Also, a tropical wave is forecast to develop into an area of low pressure in the Bay of Campeche, and this will send some tropical moisture our way.  Therefore, we will be partly cloudy with spotty to isolated showers and thunderstorms this weekend.  Highs will be in the lower 90s and lows in the lower 70s.

Tropical Outlook:  Today is the peak of the Hurricane Season and it is living up to its name!  Tropical Storm Gabrielle has come back to life this morning!  It got stronger last night and regained tropical storm strength.  It is located 185 miles south of Bermuda with 40 mph winds.  It is moving to the north at 14 mph and will track over Bermuda in the next day.  It is forecast to get a little stronger, but stay a tropical storm and it will not impact the U.S.

Tropical Storm Humberto continues to get stronger and is forecast to become the 1st hurricane of the 2013 season.  It is located near the Cape Verde Islands with 65 mph winds.  It is expected to become a hurricane later today.  This means it will not set the record for the latest forming hurricane.  Humberto will track out at sea as it moves to the WNW at 9 mph and then turns north on Wednesday.  It is expected to become a Category 2 storm sometime Wednesday.

Lastly, there is a tropical wave located over the NW Caribbean.  It will move over the Yucatan Peninsula between today and Wednesday.  Then it is expected to emerge over the Bay of Campeche by Thursday.  Forecast models show that this wave will develop into an area of low pressure, and it could become a tropical depression as well.  NHC is giving this system a high chance of becoming a tropical cyclone during the next 5 days.  Fortunately, it looks like it will track to the west and make a "landfall" over Mexico.  This is thanks to the ridge of high pressure and trough of low pressure over the U.S.  Those features are keeping the low well south of the U.S.

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

Take the umbrella with you just in case you run into a shower.  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 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.
