Strong To Severe Storms Possible On Saturday

Today will be a transition day between the pleasant weather we've had and some stormy weather that will arrive on Saturday.  An upper-level and surface low/trough will be moving across the Southern U.S. today and tomorrow.  We will stay ahead of it today.  That means you can expect a day with mostly cloudy skies along with a few isolated showers.  It will still be warm with highs in the lower 80s

A squall line of thunderstorms will form ahead of a cold front over Texas today.  These storms will move east into Louisiana tonight.  The latest forecast models show the line weakening as it get to LA overnight.  We will be well ahead of the line here in New Orleans, so expect mostly cloudy skies with a few showers or storms tonight.  Lows will be in the upper 60s.  

The squall line looks to break up by the time it gets to New Orleans on Saturday Morning.  However, we will have an unstable environment over us, so I am expecting scattered showers and storms to develop throughout the day.  Some of these storms could be strong to severe.  SPC has placed us in a Slight Risk for severe weather on Saturday.  The main threat would be damaging winds, but a few tornadoes and hail are possible too.  It will be a warm and humid day with highs in the lower 80s.  

A cold front will stay just north of us on Saturday Night, but it will be close enough to sweep the storms away from us.  We will be partly cloudy and mild with lows in the mid to upper 60s.  

Sunday will be a pleasant day with plenty of sunshine.  It will be unseasonably warm with highs in the lower 80s.  

Another upper-level low will move through on Monday.  This will set off isolated showers and thunderstorms over the region.  Some of the storms could be strong.  Highs will be in the 80s.  Tuesday and Wednesday looks pretty dry with highs still in the 80s.  A cold front looks to be headed our way on Thursday into Friday.  Scattered showers and storms are expected, and some could be strong.  I will keep a eye on this as we head into next week.

Near Record Highs Again Today In New Orleans

Today will be another unseasonably warm day as a weak stationary front sits over us.  The front will dissipate and we will have partly cloudy skies.  Expect near record highs in the lower 80s.  The record is 84° set back in 1995.  Clouds will be on the increase tonight, so expect mostly cloudy skies with some patchy fog.  Lows will be in the mid 60s.  

A weak disturbance will be just west of us on Friday. This will keep us mostly cloudy and we will have a few showers.  Highs will be around 80.  During the day on Friday, a squall line of storms will move across Texas and it arrives in Louisiana on Friday Night.  Some of these storms will be strong to severe over Western Louisiana.  It looks like this line of storms will arrive in the New Orleans area after sunrise on Saturday.  Therefore, most of Friday Night will be mostly cloudy with lows in the 60s.  

The disturbance will move over the area and send the squall line through the region on Saturday Morning.  Right now, it is forecast to arrive between 7 AM on the Northshore, in the city around 11 AM and clears the area around 3 PM.  Some of the storms could be strong to severe.  SPC has put us in a Slight Risk for severe weather.  The main threat would be damaging winds, but we could also see large hail and a few tornadoes. Once the line moves through, we will have some lingering clouds and a few showers through the afternoon.  Highs will be around 80.  

Sunday will be a partly cloudy, dry, warm and breezy day with highs in the lower 80s.  

A few showers and storms are possible on Monday and Tuesday as another disturbance moves through.

Near Record Highs Possible In New Orleans Today

We will have partly cloudy skies again this afternoon as the area of high pressure remains over the Northern Gulf of Mexico.  A weak backdoor cold front will move through today.  It will not impact our weather as it moves through.  We will just see a shift in the winds from the SW to NW, and this will make it a little less humid.  It will stay unseasonably warm with highs in the lower 80s. The record high for today in New Orleans is 83°, and we will make a run at tying it today!   Tonight will have some clouds with patchy dense fog again.  Lows will be in the 60s.  

The weak backdoor cold front will move into the Gulf and dissipate on Thursday.  We will be partly cloudy with highs in the lower 80s.  

Friday still looks to be the transitions day between the nice weather and some stormy weather on Saturday.  We will be partly to mostly cloudy with a slight chance for a shower or storm.  Highs will be in the lower 80s.  

Our weather will go downhill on Friday Night as a squall line moves into the area from Texas.  This line of storms could be strong to severe by Saturday Morning across the city.  SPC currently has us under a Marginal Risk for severe weather at this time.  As we get closer to Friday I will have a better idea of the timing and intensity of the storms.  Stay tuned for updates.  Low temperatures will be in the 60s.  

Once the squall line of strong to severe storms moves through in the morning, we will see some lingering rain showers on Saturday afternoon.  High temperatures will be down a little thanks to the rain as they climb into the upper 70s.  

The cold front associated with the squall line will stay north of us, so we will not cool down on Sunday.  We will have a pleasant day with partly cloudy skies and highs in the lower 80s.

Foggy Mornings With Unseasonably Warm Temperatures This Week

Our quiet weather pattern continues today as an area of high pressure stays over the Northern Gulf of Mexico.  Once the fog dissipates, we will be partly cloudy and warm with highs in the lower 80s.  More dense fog is likely tonight with mostly clear skies.  Lows will be in the 60s.  

Wednesday and Thursday will also be unseasonably warm and humid with more dense fog each morning.  Highs will be in the lower 80s and lows will be in the 60s.  

Our weather pattern will start to break down on Friday ahead of a cold front.  We will have more clouds and isolated showers over the region.  It does stay warm with highs around 80.  Some rain and storms will return on Friday Night with lows in the 60s. 

Saturday will be mostly cloudy with scattered showers and storms.  Some of the storms could be strong ahead and along the cold front.  It is possible that a squall line will form west of us and move through during the evening hours.  Right now, the main threat would be strong winds.  I will have to see how this system evolves throughout the week.  By Friday, I will have a better idea on the timing and strength of the storms.  Highs will be in the upper 70s.  The rain and storms will continue into Saturday Night with lows in the 60s.  

As of right now, the rain looks to come to an end on Sunday Morning.  We will then be partly cloudy, but we will not cool down behind the front.  Highs will be around 80.

Spring Is Officially Here and It Will Feel Like It!

Spring officially arrived at 5:28 AM today, but it has felt like Spring here for the last few weeks!  

We will feel like Spring today as high pressure sits in the Central Gulf of Mexico.  This will keep SW winds over us today with partly cloudy skies.  High temperatures will be in the lower 80s.  Tonight will be partly to mostly cloudy with patchy fog.  Lows will be in the 60s.  

Tuesday through Thursday will continue to be warm and delightful even as a dry cold front moves through Wednesday Night.  It will be mostly sunny to partly cloudy each day as the area of high pressure remains in the Gulf.  We will have daily highs in the lower 80s.  Lows will be in the upper 50s north to lower 60s south of the lake.  

Friday will be a transition day from the nice weather to some stormy weather as a strong cold front heads our way.  We will be mostly cloudy with a slight chance for a shower.  Highs will be around 80.  Friday Night will be mostly cloudy with scattered showers and thunderstorms.  Lows will be in the 60s.  

The cold front will move through on Saturday.  It will set off scattered showers and storms as it taps into Gulf Moisture.  Some of these storms could be strong to possibly severe.  I will have a better idea on the strength of the storms by Friday.  Highs will be in the mid 70s.  

We clear out the rain on Sunday with mostly sunny skies.  We will not cool-down behind the front as highs will be in the upper 70s.
