Seems like late Mardi Gras is always wet


March Mardi Gras is always wet, and early Feb is always cold.

OT but do you see us getting out of this EL Nino weather pattern in the next couple of weeks?

Usually these late Mardi Gras are pretty nice weather wise It's the mid February ones that are hit or miss on the weather

The short range has been a struggle this week. Didn't pick up on any of this coming in from the SW. Hopefully it's over once this round is through, at least for the parades.

I’m going to the Endymion extravaganza sat night and planning to somehow push it into Thoth. Hopefully it stays dry.

I am assuming many of those guys ride in Proteus and some others and have to attend Comus Ball on Monday so no reason to go through this weather and no time to reschedule

My wife tried to talk her brother and niece out of coming this Friday and staying until Monday morning before heading back home out of state.

The weather looks like it's going to suck big time and be nasty for a lot of the parades this weekend.

Not much different now. After noon Sunday still with storm potential. The NWS discussion this afternoon brings some hope though, as they are expecting a squall line instead of some messy storms popping off in front. Which would narrow the window, but the when of it's certain enough for me to say.

They brought up another interesting observation I hadn't noticed that COULD reduce the concern on storm strength as well.

quote:

Models seem to be showing some stabilization influence from cooler lake and near shore waters to lessen threat below the tidal lakes, but this is too close to hang high confidence at this time.


If this is the case, the surface south of the lakes would be just a little bit cooler and a little dryer. In effect, leaving a layer that's slightly warmer above the surface. Meaning air rising off the surface would want to sink.

This limits energy available for updrafts. Which lowers the rainfall potential and storm strength lightning.

Good catch by the LIX office. It's way too subtle to bank on as they noted, but gives some hope for lesser impacts in New Orleans.

GFS Soundings for noon Sunday:

1) Baton Rouge



CAPE 2000 j/kg. Note the dotted line running right of the red line. The rising air would be warmer than the surroundings, and want to keep on rising.

2) Approx Mandeville



Same story. CAPE at 1800ish. Whole profile unstable.

3) New Orleans



MU just at 700.

I'll be keeping an eye on this going forward.

Pretty good. The system that's leaving tonight is going to drape a stationary front somewhere across SELa tomorrow. Not much of a difference on temps, but it'll be a focus for showers. They shouldn't be long lasting though.

Quick update this morning.

Showers to fire along a weak front that'll be near NOLA late morning into early afternoon. Expected to fade later.

Sunday rainfall from WPC:
