Just starting to rain lightly here but the winds are nothing. Pressure falling pretty steadily today here at my ranch.

Light precipitation here at Mobile. The heavier local precip is along the Mississippi Coast and north along I-59 towards Hattiesburg.

Salute!

The worst stuff seems to be back on the LA/MS/AL border.

We are way behind the predictions here on the Panhandle.

Looks south of Mobile bay with almost all the lightning strikes and precipitation on the northeastern quadrant.
Very dry near and just south of the vort.

The vort center is moving north but dry shear has over run.
Panhandle should get the rain to the east if it doesn't completely dry out before landfall.

on radar it’s looks like it’s moved NNW.

Salute!

Turning out to be a nothingburger over here in the Panhandle east of Pensacola. Even NWS now calling for an early end to our rain.

I hope this pattern holds up all summer ... don't need a lotta storms, and we can dream huh?

It’s cold here. Low Clouds are moving in from the ESE but it’s like 64 or so. Maybe we’ll get more drizzle but the main rains look to be between Slidell and Gulfport.

About 59-60*F here. Light to occasionally moderate rain. Little wind. A rather typical early Spring Gulf low.

Waaaay too early for any fireworks, but it was an interesting little test run.

I believe it. Reports of some power lines down and some power outages overnight.

Care to back that up with more than lines you drew on a satellite image? I really don't know where you're getting that "cold front" from.


Dew points were in the lower 60s to its west and 70s to its east. It's the front that moved through Texas last weekend. Dew point temperatures and wind shifts are both ways to identify an airmass. Northerly winds at Tampico and southerly in Veracruz. The airmass over Texas and the NW Gulf west of the low was definitely not maritime tropical, it was modified Canadian air. The air southeast of the low was maritime tropical. Two different airmasses. Thus, a front between them. That stationary front just doesn't stop at the low center. Heck, it's in the mid 50s along the Texas coast this morning. The low produced a secondary surge of Canadian air across Texas and the NW Gulf. I've been doing meso-analyses of frontal boundaries across TX and the NW Gulf since the late 1970s.

This morning's analysis has the cold front well past the offshore platforms and buoys all the way to Mobile. It's better defined across the Gulf than east of the low across northern Florida. Same front that was there yesterday. Could draw an occluded front coming out of the low, I suppose.

HRRR was the worst model with this system. It kept trying to develop a tropical core in a very high wind shear environment. The low center remained exposed south and southwest of any convection due to the strong shear.
