A Soggy Christmas Week With Some Severe Weather

Scattered to numerous showers and thunderstorms are moving into the New Orleans area this afternoon and will continue through the evening. Some heavy rain is possible, but major flooding is not likely. You can expect typical street flooding. Some of the storms could be strong to severe. SPC has put all of South Louisiana in a Marginal Risk for severe weather. The main threat would be damaging winds. Highs will be in the mid 70s.

The rain will taper off after Midnight, and we will be cloudy with just a few showers. Patchy fog will be possible. Lows will be in the lower to mid 60s.

More showers and storms will follow on Tuesday and Wednesday. A few storms could be strong to severe with damaging winds and a few tornadoes each day.  However, the best chance for severe weather will be on Wednesday.  The forecast models are not in total agreement as to whether the severe weather threat will be over us, or farther to the north of Louisiana.  SPC has us in a Marginal Risk on Tuesday and Wednesday, but parts of SE LA are in a Slight Risk on Wednesday (See image to the left). Needless to say, I will keep an eye on it.  

The forecast models are also showing heavy rain each day, and rain totals between Monday and Wednesday could be around 2-5 inches. Again, major flooding is not likely since we have been dry lately, and the rivers/streams are low. However, typical street flooding will be possible in areas that usually see high water.  Remember, DO NOT drive through flooded roadways!  Highs will be in the mid 70s each day and lows will be in the mid 60s.

For Christmas Eve and Christmas Day: Rain chances will decrease some compared to earlier in the week scattered showers possible Thursday, but only isolated showers are now in the forecast for Christmas Day, Friday. The forecast models are now coming in better agreement and show the decreased chance for rain. However, keep the umbrella handy as it will not be totally dry. It will stay unseasonably mild with high temperatures in the 70s both days, and low temperatures in the 60s. 

The early outlook for the weekend calls for a decreased chance for rain around 20-30% each day and highs in the 70s, lows in the 60s.

Make sure you keep it tuned to WWL-TV each day, and follow my Facebook and Twitter feeds for updates!  -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 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 ...

Flash Flood Watch now until Thursday Evening for WBRZ Viewing Area

The NWS in Slidell, LA has issued a  Flash Flood Watch for all of the WBRZ Viewing Area starting now and continuing until Thursday Evening. Rain has been falling for the last few hours and we have already picked up over 1.30" in Baton Rouge.  This is WAY more than the forecast models were predicting for this time.  The area of low pressure continues to develop over South Texas and a warm front will move up from the Gulf of Mexico by Wednesday Morning.  This will spread widespread rain and a few thunderstorms over Southern Louisiana all night and into Wednesday.  Then it looks like we will taper off the rain to just scattered showers during the day on Wednesday. On Wednesday Night, a cold front will move out of Texas into Louisiana.  As this happens, a squall line of thunderstorms is expected to move ahead of it and through Baton Rouge on Thursday Morning.  Some of these storms could be strong to severe with damaging winds and a few tornadoes. ...
