Possible Frozen Precipitation Friday Afternoon and Evening Across SE LA

I'm sure you have already heard that we could see some frozen precipitation across part of Southeast Louisiana and Southern Mississippi starting on Friday Afternoon and continuing until around Midnight into Saturday.  However, DO NOT get excited about this winter weather event.  It will not have a big impact on our area.  The NWS has issued a Winter Weather Advisory for Northern Tangipahoa and Washington Parishes as well as Pearl River, Pike and Walthall Counties in Mississippi. 

 A cold front will move across the region tonight and it will bring us some rain for the first part of Friday.  As the rain comes to an end on Friday Afternoon and Evening, the temperatures will be falling to near freezing at the surface.  This will give us an opportunity to see some freezing rain or sleet north of the lake.  

 Since the ground is warm and the precipitation will be coming to an end, I am NOT expecting any accumulations.  You will likely just hear the sleet pellets bouncing off things, or you could see a VERY light glaze of ice on trees around 0.05-0.10".  There is a chance for a few slick spots on roads along and north of I-12 through the LA/MS state line on Friday Night into Early Saturday Morning.  Then this could change to snow flurries before it ends early on Saturday Morning. Again, no snow accumulation is expected. I would not plan to travel late on Friday Night into Saturday Morning. Bridges and overpasses would likely be the only spots to ice over.  

 Here in New Orleans, we could see a sleet pellet or two, but that would be about it as the rain ends.  Again, I am not expecting any travel concerns.  

 After this wintry weather episode, the temperatures will be very cold Friday Night through Sunday.  It will also be windy, so this will put an extra chilly into the air.  We will see plenty of sunshine all weekend, so wintry precipitation is not expected.  High temperatures will only be in the 40s, but it will feel like the 20s and 30s with the wind chill! 

 The next issue will be the hard freeze that is expected on the Northshore with lows in the lower 20s, and freezing conditions on the Southshore, including the City of New Orleans, with lows in the upper 20s to lower 30s. You will need to take all freeze precautions this weekend on BOTH sides of the lake.  As for freezing pipes...you may want to wrap your pipes on the Northshore this weekend.  It is unlikely that they will burst, but conditions will be close for that to happen.  South of the lake will NOT have pipe bursting temperatures, but you will need to protect you plants, pets and people.  

 Be sure to stay warm all weekend and keep it tuned to my social media accounts and WWL-TV for updates. -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.
