Winter Storm WARNING now in effect for Tuesday

...Winter Storm WARNING from 6 AM Tuesday Until 6 AM Wednesday...

As I've been talking about the last few days, our next winter storm is upon us.  Right now, a cold front is moving into Southeast Louisiana.  This front is setting off some scattered showers across far SE LA and they will continue into the afternoon hours.  High temperatures will be in the lower 60s this afternoon.

Once the cold front moves through this afternoon/evening, the temperatures will start to fall.  This will be the leading edge of the cold air heading our way.  The rain will come to an end, and we will be left with mostly cloudy skies.  Low temperatures will fall into the upper 20s north of the lake and the lower 30s south.

Tuesday's Winter Mess:  The Winter Storm Warning begins on Tuesday at 6 AM and goes until 6 AM Wednesday due to the fact we will have some hazardous winter weather and it will make traveling treacherous! 


We will start out on Tuesday Morning with cloudy skies and some rain/freezing rain/sleet mix will begin mid-morning for the Baton Rouge area to McComb, MS as a disturbance moves out of Texas to the Louisiana Coast.  That will be the system responsible for giving us the wintry weather.  South of the lake will be scattered rain showers developing since we will be just above freezing.


As the morning progresses, the wintry mix will start spreading south toward New Orleans where the rain will mix with some freezing rain as we will have a temperature around 32°.  The Northshore will likely see more sleet and some snow falling, and the snow could start to accumulate around Baton Rouge.  Temperatures will be around 30°.

During the evening hours, more sleet will be mixing with the freezing rain around the New Orleans area and some significant icing could occur.  We could see 1/4" of ice on roads, trees and power lines.  While that does not seem like a lot of ice, IT REALLY IS!  That is enough ice to make tree limbs fall and power lines to break.  Power outages will be very possible by Tuesday Evening!  The Northshore will have more sleet and snow for the rest of the afternoon and into the evening.  Snow/sleet accumulations could be around 1-2 inches with some spots getting even more.  The heavy wet snow could also bring down tree limbs and break power lines.  Again, power outages will be possible!  PLEASE be prepared if the power goes out.  Unlike when we get hit by a hurricane, when the power goes out this time of year it will be COLD in your homes.  Have the supplies you need to keep warm NOW!

The wintry mix will come to an end overnight into Wednesday Morning.  You can expect icy spots all across Southeast Louisiana.  Many roads may be closed due to iced over bridges and overpasses.  Surface streets may also have some ice, especially the ones that could be covered in snow.

Wednesday's Outlook:  We will not get warm on Wednesday, but the sun will return during the afternoon.  High temperatures are expected to get just above freezing in the mid to upper 30s, so we will have some melting of the ice.

Wednesday Night will be clear and very cold with low temperatures in the 20s.  Anything that would have melted, and did not dry out, is expected to refreeze again.  This could lead to some more icy spots into Thursday Morning.  We will warm into the upper 40s on Thursday with lows only in the 40s Thursday Night, so all the ice should be melted by then.



NOTE:  The timing of this could change if the system slows down, or gets stronger.

Please keep up-to-date with the changing weather on Tuesday on WWL-TV and through my Facebook & Twitter feeds.  Stay safe and do not venture out into this wintry mess!  -Dave

Comparison between Hurricane Matthew's possible forecast track loop vs Hurricane Betsy's

Some of you have been calling to say that Matthew's forecast to do a loop in the Atlantic Ocean off the SE U.S. is the same as what Hurricane Betsy did back in 1965. Well...that is not true. Betsy formed on August 27, 1965 just off the Leeward Islands. It quickly became a tropical storm on the same day, and then became a hurricane on August 29.  It made a few loops in its track with one north of Puerto Rico and a second north of the Bahamas.  There is a strong area of high pressure that was preventing Betsy from moving to the north, and that is what caused it to loop.  After the second loop, it then moved SW across the Bahamas, then turned west to move over far South Florida and then into the Gulf.  It eventually turned to the NW and quickly tracked right to New Orleans where it made landfall as a major hurricane on September 9th. Hurricane Matthew formed in the Atlantic east of the Leeward Islands as a tropical storm on September 28. It quickly moved west into t...

The Great Flood of 1983

It was 30 years ago that the Baton Rouge area experienced what is likely the worst flood in its history!  On April 5-9, 1983 we were hit with 6 to 13 inches of rain from a slow-moving storm.  This rain quickly ran off into the Amite, Comite, Tickfaw and Tangipahoa River Basins.  Some of the highest rainfall totals were in the headwaters of the Amite River in the Felicianas and South Mississippi.  Also, there were some strong easterly winds which slowed down the water from draining into Lake Maurepas and Pontchartrain.  These were some of the reasons why the flooding occurred in Baton Rouge & Denham Springs.  The weather map to the right shows the weather for April 8, 1983. A stalled front over the Southeast U.S. lead to the heavy rain event and flooding. The rivers quickly rose and spilled out of their banks.  The rain didn't stop, so the water continued to rise and rise.  Rivers rose to what are still the record levels.  The Amite in D...

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 ...
