Cold Front Moves Through With Windy Weather Today

*Wind Advisory until Midnight*

A strong cold front will finally move through today.  We will have some showers and a few thunderstorms as it moves through during the morning hours.  A few storms could be strong to possibly severe with large hail being the main threat.  Once the front moves through, it will be partly cloudy with very windy conditions.  Winds will be out of the west at 25-30 mph with higher gusts.  A Wind Advisory is in effect until Midnight. High temperatures will be around 70.  

We will be partly cloudy and windy tonight.  It will become much cooler with lows in the upper 40s north and lower 50s south.  You will want a jacket on Monday Morning! 
High pressure will build over us on Monday and Tuesday.  Monday will be sunny and cool with highs in the lower 60s.  Monday Night will be clear and chilly with lows in the 40s on both sides of the lake.  Tuesday stays sunny, but it will be a tad warmer with highs around 70.  

Our next cold front arrives on Wednesday.  It will bring us a few showers, but no severe weather.  We will be mostly cloudy with spotty showers.  Highs will be in the mid 70s ahead of it.  Wednesday Night will be partly cloudy and it will turn cooler with lows in the 40s north and 50s south.  

High pressure will build over us again on Thursday through the weekend.  We will be MUCH COOLER with highs around 60 on Thursday, but we will only be in the 50s on Friday through the weekend!  Lows will be in the 30s north and 40s south.  Finally Winter temperatures return to New Orleans!

Severe Weather Possible Overnight and On Saturday

Today will be a relatively quiet day weather wise.  What is left of the cold front is stalled and falling apart along our coast.  We will have a mix of sun and clouds today with just a slight chance for a shower for mainly the coastal areas.  It will be very mild with highs in the upper 70s.  

Up in Washington, D. C. it will be cloudy and chilly with scattered showers for the Presidential Inauguration.  Noon Eastern Time temps. will be in the 40s with rain. High temperatures will be in the upper 40s to lower 50s. Check out this link for a look back a past weather on Inauguration Day.

The weather will quickly change from good to bad tonight.  A disturbance aloft (upper-level low) will move across the state and this will help to set off some strong to severe storms!  SPC has us in a Slight to Enhanced Risk for severe weather tonight, but it could be upgraded to an Enhanced Risk.  Our atmosphere will quickly become unstable as this system moves through.  The main threats would be damaging winds and a few tornadoes.  The storms will likely move through while many of you are sleeping, so keep you weather radio and weather apps on standby to give you the weather alerts.  Lows will be in the mid 60s.


The severe weather threat will continue into Saturday. The disturbance will move east of us, but we will remain very unstable ahead of a cold front.  Scattered showers and thunderstorms will develop during the day across the region.  Any storm could become strong to severe.  The main threat is very large hail, but we could also see some damaging winds and a few tornadoes.  SPC has us in a Slight Risk for severe weather, but this could also be upgraded to an Enhanced Risk.  I think the greatest area that will see severe weather will be along and north of I-12 into Mississippi.  Needless to say, you will need to be weather aware throughout Saturday.  Fortunately, I'm not expecting any widespread severe weather, but it is still possible for everyone.  Highs will be near records as we climb to around 80°.  Some rain and storms are possible Saturday Night, but the severe weather threat will move east of us.  Lows will be around 60. 

The cold front will move through on Sunday Morning.  We will see a few showers and storms along the front as it moves through.  However, they are not expected to be severe.  Then we will stay mostly cloudy through the afternoon.  It will become very windy behind the front with winds around 15-25+ mph.  Highs will be in the lower 70s.  

Much cooler air will arrive to start next week with highs in the 60s on Monday and Tuesday under sunny skies.

Strong to Severe Storms With Heavy Rain Today and Again on Saturday

*DENSE FOG ADVISORY for most of SE LA/MS coastal counties areas until 9 AM Thursday*
*MARINE DENSE FOG ADVISORY for Lakes & Gulf until 9 AM*

Watch out for more dense fog this morning, especially over areas of water.  We will also see a few showers developing throughout the morning ahead of a cold front.  

The rain and thunderstorms will become more widespread this afternoon and evening along and ahead of the cold front.  Some of the storms could be strong to severe with damaging winds and large hail.  SPC has us in a Marginal Risk for severe weather.  It looks like a broken line of storms will move through the Metro New Orleans area between 2 to 6 PM.  We will also have heavy rain today and we could pick up 1-2" of rain. Watch out for some minor street flooding issues today.  Highs will be in the mid 70s.  

The rain will come to an end tonight as the cold front moves east of Louisiana.  It will remain mostly cloudy and mild with dense fog possible.  Lows will be in the  lower 60s. 

Friday will be a quiet day between the storms today and a stormy weekend. It will be partly cloudy, mild and muggy with near record highs in the upper 70s.  

The weather will go downhill starting on Friday Night into Early Saturday Morning.  A disturbance will track across the state and this will move into a very unstable atmosphere.  This will set off scattered thunderstorms that will likely be severe.  They could contain damaging winds, large hail and a few tornadoes.  SPC has us in a Slight Risk for severe weather during this time.  

Once the disturbance moves through, we will see a lull in the rain until Saturday Afternoon as the cold front moves over us.  Then another round of showers and storms will develop and move through.  These storms could also be strong to severe.  Highs will be in the upper 70s and it will be breezy.  

The rain and storms will continue into Saturday Night/Sunday Morning.  We will have to keep an eye on these as well.  Lows will be around 60.  

The cold front will move through on Sunday.  We will still have some scattered showers and storms, but the atmosphere will not be as unstable, so these storms are not expected to be severe.  Otherwise, it will be mostly cloudy and cooler with highs in the upper 60s.  

Then cooler and drier air arrives to start the new week with partly cloudy skies and highs only in the 60s.  Lows will be in the 40s.

Near Record Highs Today & Strong to Severe Storms Possible Thursday

*DENSE FOG ADVISORY for Land areas until 10 AM*
*MARINE DENSE FOG ADVISORY for Lakes & Gulf until 11 AM*

More dense fog is expected throughout the morning and across the entire area. Visibility will be less than 1/4 mile in many places. Fog restrictions are in place on the Causeway. Drive safely and take your time!  

After a foggy start to this Wednesday, we will be mostly cloudy and still very mild this afternoon with spotty showers.  Expect some near record highs in the upper 70s again.  The record is 79° set back in 1974.  

The weather will start to change and go downhill tonight ahead of a cold front.  We will be mostly cloudy with some fog, but scattered showers and thunderstorms will move into the region toward daybreak.  Some heavy rain will be possible.  Lows will be in the mid 60s. 

The strong cold front will move through on Thursday.  It will be very mild and humid ahead of it, so the atmosphere will be unstable.  This will allow for the thunderstorms to become strong to possibly severe at times.  The main threat would be damaging winds and hail, but a few tornadoes are possible.  Heavy rain is also likely, and we could pick up 1 to 2 inches of rain.  However, I'm not expecting any flooding issues since it has been dry lately.  Just watch out for street flooding.  Highs will be in the mid 70s.  The rain will gradually come to an end on Thursday Night as the cold front moves through.  We will not cool down with lows in the 60s and some patchy fog will be possible.

Friday will be a dry day as we wait for our next cold front that arrives on Saturday.  Expect partly cloudy skies and mild highs in the mid 70s.  Rain and storms return Friday Night with lows in the 60s.  

The cold front that is headed our way on Saturday could bring us some severe storms.  We will be very mild and humid with highs in the mid 70s ahead of the front, and that will make it unstable again.  These storms could bring us damaging winds, hail and a few tornadoes.  It looks like the severe weather threat will be greater on Saturday vs. Thursday.  We will have to keep a close eye on the storms.  Heavy rain is also likely and we could pick up 1-2 inches.  However, I'm not expecting any flooding issues.  

The storms will continue on Saturday Night into Sunday.  Again, they could be strong to severe.  Lows will be in the 60s.  The storms will come to an end during the day on Sunday as the cold front moves through.  Highs will be around 70.  

Much cooler air arrives on Monday with highs in the 60s under sunny skies.

Near Record High Temperatures Expected Today, Storms Return Thursday

MARINE DENSE FOG ADVISORY until 9 AM for Lakes & Gulf waters

We will have some dense fog across Lake Pontchartrain and other area lakes this morning. Drive safely across the Causeway, Twin Spans and Spillway.  Visibility could be less than 1/4 mile at times.  Restrictions are in place for the Causeway this morning, so plan accordingly. 

We will have more of the same weather today across Southeast Louisiana.  That means more fog with mostly cloudy skies and a slight chance for rain.  Expect near record highs in the upper 70s. The record is 79 set back in 1974.  Tonight will have more dense fog possible with mostly cloudy skies and a slight chance for a shower.  Lows will be in the lower 60s. 

Wednesday will continue to be unseasonably mild and humid ahead of a cold front.  We will start out the day with some dense fog.  Then it will be mostly cloudy with a slight chance for a shower. Highs will be in the upper 70s - near records!  

The next cold front will actually move across the region on Thursday.  We will be very mild and humid ahead of it, and the atmosphere will be unstable.  Expect scattered showers and thunderstorms starting early on Thursday and lasting through Thursday Night.  Some of the storms could be strong to possibly severe with damaging winds. Heavy rain is also likely.  We could pick up 1-2"+ on Thursday, so watch out for minor flooding issues.  Highs will be in the mid 70s.  Lows will be in the 50s north and 60s south Thursday Night as the rain slowly comes to an end.

Friday will be a dry day with plenty of sunshine, but it will not cool down behind the cold front.  We will stay unseasonably mild with highs in the mid 70s.  

Our next cold front will arrive on Saturday/Sunday.  This front will be much stronger and there is a better chance for strong to severe storms along with heavy rain.  We will have to keep an eye on this system as it develops off the West Coast of the U.S. the next few days.  Plan for some rough weather all weekend with highs in the 70s on Saturday, but 60s on Sunday.  

Then it looks like we will return to more normal temperatures for this time of year on Monday.  It will be sunny and breezy with highs in the lower 60s and lows will be in the 40s.
