More Heavy Rain Today With Flash Flooding Possible For The New Orleans Area

FLASH FLOOD WATCH is in effect until 7 PM Today for much of Southeast Louisiana - except the Coastal areas. An additional 1-3" of rain will be possible, which could lead to more street flooding. Remember, don't drive on flooded roads!! 

Get ready for another round of heavy rain and storms today!  A cold front remains stalled NW of our region again today, and when you add that to the very moist air mass over us, that will lead to a heavy rain threat.  The storms will develop this morning and continue all day.  This will once again cause issues with Jazz Fest and the Zurich Classic.  Some of the storms could be strong to severe with large hail, damaging winds and even a tornado or two.  

Rain totals could be around 1-3" with some areas receiving even more.  This is why the NWS extended the Flash Flood Watch until 7 PM tonight.  High temperatures will try to make it into the lower 80s.  


The rain and storms will taper off this evening, and then briefly dissipate tonight.  Storms are expected to redevelop toward daybreak on Monday.  Otherwise, it will be mostly cloudy, muggy and mild with patchy fog.  Lows will be in the 60s north and 70s south.

Monday will be a repeat of today with storms developing in the morning and lasting throughout the day.  Expect more heavy rain, and the flash flood watch could be extended as additional rain totals could be around 1-3".  Highs will be in the lower 80s.  

FINALLY, this front will move through on Tuesday, but it will still give us one more day of rain and storms.  However, it the forecast models are not showing as many storms.  Highs will be in the lower 80s.  

A much needed break in the rain will arrive on Wednesday and we will stay dry through the weekend.  We will also see a break in the humidity too!  Get ready for plenty of sunshine and highs in the upper 70s to around 80.  Lows will be in the 50s north and 60s south.  A VERY refreshing end to the week!

More record warmth today, but some severe weather is possible tonight into Monday

You can expect another very unseasonably warm and humid day across Southeast Louisiana with some record highs!  Record highs are 80 for New Orleans and Audubon, and 78 for Slidell.  We will be mostly cloudy and could see an isolated shower or storm with highs in the lower 80s.  

The weather will change beginning tonight as a strong cold front moves toward the New Orleans area.  Showers and storms will form ahead of a squall line that will move toward us from Texas.  Ahead of that line, we could see scattered thunderstorms, and they could be strong to severe with a few tornadoes, damaging winds, hail and heavy rain.  SPC has us in a Slight Risk for severe weather tonight/Monday Morning.  Lows will fall to the upper 60s.  Make sure you stay tuned to WWL-TV and my Facebook and Twitter feeds for weather updates! 

Monday Morning will start out stormy as the squall line and cold front move into New Orleans between 5-8 AM.  These storms could also be strong to severe with a few tornadoes, damaging winds, hail and heavy rain. Once the cold front moves through, temperatures will fall and it will become windy.  High temperatures in the upper 60s will occur in the morning, but they will fall to the lower 60s by late morning and drop into the upper 50s by the late-afternoon.  

Any rain will end by Monday Night and we will continue to be mostly cloudy and breezy.  We will become much cooler with lows in the 40s.  

Tuesday will be a mainly dry and cooler day with mostly cloudy skies and highs around 60.  Tuesday Night will see a change in the weather again as the cold front retreats back to the north.  This will give us steady temperatures around 60, but it will bring us scattered showers once again.  

Wednesday will be another stormy day as the cold front continues to move to the north.  Some heavy rain will be possible along with scattered thunderstorms.  I'm not expect any severe weather at this time, but a few storms could be strong with gusty winds.  Highs will be in the mid 60s.

We will finally start to dry out on Thursday and this drying trend continues into the weekend.  We will also become MUCH COOLER with highs only in the 50s for the rest of the week!  Finally some Winter Temperatures!  Lows will be in the 40s.

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.

A Warming Trend Starts Today and Continues Through Thanksgiving

High pressure is moving to the east of Louisiana today, and that will shift the winds from the northeast to the east. This will start to warm us up and keep it mild for the rest of the week. Moisture is also moving back over us, and that has brought back some clouds. We will have a mix of sun and clouds today with highs in the mid 60s. 

This evening will be partly to mostly cloudy with temperatures in the 50s. If you are headed to the Canal Street Lighting Ceremony tonight, the weather will be pleasant and cool with temperatures in the 50s at 5:30 when the turn the lights on.

It will not be as chilly tonight with mostly cloudy skies. Lows will be in the upper 40s north and mid 50s south. You may still want a light jacket tomorrow morning.

The breezy winds will shift to the ESE for Wednesday, and we will have even warmer temperatures with highs in the lower 70s under mostly cloudy skies. We could see a spotty shower too, but most of you will remain dry.

The outlook for Thanksgiving has us mostly cloudy, breezy and mild with highs in the mid 70s. There will be a slight chance for a shower at 10%. Black Friday Morning looks good for all of you shoppers! It will be mostly cloudy with patchy fog and mild temperatures in the 60s on both sides of the lake.

The weekend will continue to be mostly cloudy and mild with a slight chance for rain on Saturday at 10%, but we will have a 30% chance for rain on Sunday ahead of our next cold front. Highs will be in the 70s and lows in the 60s each day.

Thanksgiving Week Weather Outlook...changes are coming!

We will have one more cool day before a warming trend starts across Southeast Louisiana. High pressure remains over us today and that will keep the cool northeasterly winds over us. It will be clear, but highs will only be in the upper 50s. It will stay cool and nice this evening with temperatures in the 40s, so you will will want a jacket. 

This will be the last chilly night of the week, but only a few spots may get to freezing. Some high clouds will move over us and the area of high pressure, which has the coolest air beneath it, moves to the east of Louisiana. Lows will be in the lower to mid 30s north of the lake and mid 40s south. You will want to cover or bring in your plants on the Northshore.  Also, you should have a warm place for your pets on both sides of the lake!  

The area of high pressure will continue moving east of us on Wednesday, and that will bring back east to southeast winds for the rest of the week. More clouds will develop as moisture moves in from the Pacific Ocean. Tuesday will be partly cloudy with highs in the 60s. Wednesday will also be partly cloudy, but it will be warmer with highs in the 70s. It will not be as cold at night with lows in the 40s north and 50s south.

Thanksgiving and Friday will be a mild and more humid with partly cloudy skies. A shower or two will also be possible, but most of you will stay dry. Highs will be in the mid to upper 70s. Lows will be in the 50s north and 60s south.
