Strong to severe storms possible across SE LA today

...Tornado Watch for SE LA Until 9 PM...

Possible Severe Weather Today:  Scattered showers and thunderstorms are starting to pop-up across SE LA this afternoon.  The atmosphere has become unstable again after the rain we had this morning.  This could cause the storms to become strong to severe with damaging winds, large hail and a few tornadoes.  SPC has SE LA in a Slight Risk for severe weather today and Washington Parish and Pearl River County, MS are in a Moderate Risk - meaning they have a greater chance of severe weather.

These storms are being set off by an upper-level disturbance, a cold front, outflow boundaries and an very unstable atmosphere.  When you add up all of these ingredients you get the threat for severe weather.  Due to all of this, SPC has issued a Tornado Watch for areas along and north of I-12 in our viewing area until 9 PM. 

Fortunately, the weather is not expected to be as violent as it was yesterday in Mississippi and Alabama.  However, that does not mean we …

Some strong to severe storms possible across SE LA today & Tuesday

A strong cold front is located to the west of Louisiana.  Ahead of it, we have a very warm, humid and unstable atmosphere with high temperatures in the mid 80s.  This could lead to isolated showers and storms popping up across Southeast Louisiana.  Some of the storms could be strong to severe with damaging winds, hail and a few tornadoes.  There is also a chance that the atmosphere will stay "capped" and we will not see any storms.  SPC has put the northern portion of the viewing area in a Slight Risk for severe weather.  Right now, it looks like we will not see many storms today or tonight, but if they can break the "cap" the storms would quickly become severe!  There is also a chance we may not see any storms!  It is definitely a tough forecast. 

The cold front will move closer to New Orleans tonight.  This will help to set off scattered showers and thunderstorms.  Any of these could also be strong to severe.  It will be a warm and muggy night with lo…

Great weekend for Jazz Fest and the Zurich Classic, stormy weather next week

Rest of Today:  A cold front will move into New Orleans today, but it is very weak.  It will not have a big impact on our weather.  We will have partly cloudy skies only only a 10% chance of a shower through the afternoon hours.  You will notice it is more humid and warm with highs in the lower 80s.

Tonight:  The front will washout along the coast tonight.  Some slightly drier air may move over the area tonight, and that will drop the humidity a tad.  Expect mostly clear skies with lows in the lower 60s.  Some patchy fog is possible too. 

Weekend Forecast:  The weekend is shaping up to be a warm and more humid one.  It will be partly cloudy with a 10-20% chance for a shower.  Highs will be in the lower 80s and lows in the upper 60s.  If you are headed to the Zurich Classic or Jazz Fest...bring a hat and some sunscreen. 

Next Week Outlook/Strong Storms:  The next chance for rain and storms starts on Monday and lasts through Wednesday.  Some of these storms could be strong to …

A cold front today, but then warm weather the rest of the week

A cold front is going to move across Southeast Louisiana on this Earth Day, but it will not bring us much rain.  Actually, the front will not live up to its name!  You can expect mostly cloudy skies with only a 20-30% chance for an isolated shower or thunderstorm.  Most of you will not see any rain.  Highs will be mid to upper 70s with a few spots making it to 80 if you see more sunshine.

The front will be along the coast tonight and we will not cool down much behind it.  There will be partly cloudy skies overnight with lows in the lower 60s.

An area of high pressure will build over us on Wednesday and Thursday.  Each day will have mostly sunny to partly cloudy skies with highs in the lower 80s and lows in the lower to mid 60s. 

The outlook for the busy weekend (Jazz Fest & the Zurich Classic) calls for partly cloudy skies on Friday, Saturday and Sunday with only a 10% chance for a pop-up shower each day.  It will become much more humid too.  Highs will be in the 80s…

Severe weather and heavy rain possible tonight

...Tornado Watch until 3:00 AM for ALL of Southeast Louisiana...
...Flash Flood Watch in effect until 1 PM Monday for all of Southeast Louisiana...
What happened to the heavy rain that I expected today??  All I have to say is it is still coming!  SPC has issued a Tornado Watch for ALL of Southeast Louisiana until 3:00 AM! 

Yesterday, the forecast models hinted at lower rain amounts from what they showed on Friday, but still the chance for some severe weather.  Today, Mother Nature threw me a curve ball and significantly slowed down the northern movement of the warm front from the LA Coast.  It has moved through NOLA & south of the front it is much warmer & more humid.  This front WILL still move northward tonight.  The atmosphere south of the front is VERY unstable & t'storms are expected to develop tonight.  Check out the temperature in New Orleans vs. Baton Rouge below:

 As a warm front moves north from the LA Coast, an area of low pressure will move from the Western G…

Heavy rain and storms likely this weekend

Friday Night:  The cold front is moving across SE LA tonight and that will push the rain and storms to the LA Coast.  Overnight, we will keep partly to mostly cloudy skies around with a few spotty showers (20% Chance).  Lows will be near 56 north of the lake and 60 south.

Saturday Outlook:  The cold front will stay stalled along the LA Coast on Saturday.  As it sits there, weak disturbances will move along it from west to east.  This will set off scattered showers and thunderstorms during the day (50% Chance).  However, the bulk of the rain will be along and south of the I-10 corridor.  North of I-10 it will be just some isolated to scattered showers/storms.  Any storm could produce heavy rain.  We will be cooler with highs struggling to reach 70.

The tail-end of the cold front will start to retreat back to the north as a warm front on Saturday Night.  At the same time an area of low pressure is expected to develop along the Texas Coast.  This low will push the warm front into LA as it…
