Not as hot with more storms and heavy rain today

Heavy Rain Today: We will have another round of scattered showers and storms today as a cold front moves in from the north.  This will help to give us a break from the heat!  The storms today will have plenty of moisture to tap into, so they will contain heavy rain.  A few storms could also be strong to possibly severe with some gusty winds and hail.  High temperatures will still get into the lower 90s before the storms develop.  Make sure you take the umbrella and rain coat today! 

Some showers will linger overnight as the cold front settles along the coast.  Otherwise, it will be mild and muggy with lows in the 70s. 

The front will remain stalled along the coast on Wednesday, so we will continue to deal with scattered showers and storms.  However, the Southshore to the coast will see the most storms.  High temperatures will remain lower thanks to the clouds and rain, and they will only be in the upper 80s. 

Thursday will be a transition day from the stormy weather and eventual drier weather.  Expect a mix of sun and clouds with scattered showers and storms.  It will be hotter since we will see more sun.  Highs will be in the lower 90s and it will feel like 95-100°.  

4th of July Weekend: An upper-level ridge will build over us on Friday and stick around until next week.  This means we will have some nice, but hot weather for the 4th of July Weekend!  Friday through Monday will be partly cloudy and hot with a slight chance for afternoon storms (20% chance).  Highs will be in the mid 90s and it will feel like 100-105°.

Scattered storms with heavy rain return today

Sunday was a scorcher. We hit a record high temperature of 100° at Armstrong International Airport on Sunday. The previous record was 98° from 2012.  At Slidell, we tied a record high temperature of 96° set in 1972. The heat index was as high as 110°.  After a very hot weekend, we will see some relief from the heat this week!  

We start this Monday off with scattered showers and storms moving in from the MS Coast.  They will contain heavy rain and plenty of lightning. This will impact the morning commute! Give yourself plenty of time to get to work today and take the umbrella.  

This afternoon will still be very hot, but we will see another round scattered showers and thunderstorms.  Some of the storms could be strong with heavy rain and plenty of lightning.  Highs will be in the mid 90s, but it will feel like 105-110°!  Look for some to continue to night with isolated showers and storms.  Lows will be in the mid to upper 70s.

The wettest day of week will be on Tuesday as a cold front moves into the area.  This front will tap into a very moist air mass and that will allow for scattered showers and storms to develop.  These storms are expected to contain very heavy rain and be slow-movers.  Street flooding issues are likely!  High temperatures will be lower thanks to the clouds and rain as they only climb to the upper 80s.  

The front will linger over the area on Wednesday, so we will continue to see scattered showers and storms.  Highs will be back in the lower 90s.  

The front will dissipate by Thursday and we will see some drier and hotter weather return through the weekend.  Each day will have a slight chance for some afternoon storms.  Highs will be in the lower 90s Thursday and Friday.  
Saturday and Sunday look to be hotter and humid with only a slight chance for storms.  Highs will be in the mid 90s feeling like 100°+.

Hot and dry weather continues through the weekend

The upper level high pressure will continue to move to the east and set up over LA/MS/AL for the next few days.  At the same time, a surface area of high pressure will remain over us too.  These highs will provide sinking air over the region and dry air aloft.  That means we will have plenty of sunshine, drier than normal conditions and hotter than normal
temperatures each day through the weekend.  There will only be a very small chance for
rain around 10% for areas along the coast.  High temperatures will be in the lower to mid 90s.  It will feel like 95-100° today and Friday.  Some added low-level Gulf Moisture moves in this weekend, and that will make it feel like 105°.  
Morning lows will be in the 70s, so it will not take much for us to heat up!  

Please take it easy if you will be working outside the next few days.  Use sunscreen, drink plenty of water, take frequent breaks, make sure pets have a cool spot and plenty of water, and don't leave kids/pets in cars.

It looks like we will have a break from the heat next week.  The areas of high pressure will retrograde to the west.  This will allow a trough of low pressure to set up along the East Coast, and that will send a "back door" cold front our way - meaning a cold front that moves in from the ENE vs NW.  This will set off scattered showers and thunderstorms starting on Tuesday with highs around 90. 

Have a great day and stay cool!  -Dave

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.
