Rainmaker for the Northern Gulf Coast

 NHC has the Northern Gulf highlighted for potential tropical development of 30% in the next 5 days. Regardless of cyclonic formation there is an increased rain chance associated with this stalled out frontal system. So here is the model estimated total rainfall for the next 5 days. EURO and GFS. #SELAWX

EURO 5 Day Rain Totals

GFS 5 Day Rain Totals

Upper Gulf Development Possible

 Computer model runs are starting to consistently sniff out a North Gulf Low pressure forming in about the 7 days' time frame. July 17-18ish. It doesn’t look like much more than a rain maker. So, all interest from the upper Texas coast to the central Florida panhandle need to watch this closely. GFS, EURO, and the ICON are all in agreement.

Wide Variety of Weather This Weekend

A wide array of weather conditions will be possible as we move into the weekend.  The heat will be on, with temperatures climbing well into the 90s each day.  Heat index values will be above 105 and could climb as high as 108 during the afternoon hours today.  Tomorrow, a marginal risk of severe weather will be in place for most of the northern part of our area followed by a marginal risk of excessive rainfall on Sunday.  Stay weather aware this weekend!

Saturday has a Marginal Risk of Severe Weather in Our Northeastern corner of Southeast Louisiana.

 

Afternoon Showers and Chance For Severe Weather

 

The showers are moving up from the Gulf. Warm moist tropical air. Some could be locally heavy with the possibility of localized flooding, street flooding, and ponding on highways. Some could produce waterspouts. I've been seeing a lot of those the last few days. Stay weather aware and drive safely.

Today’s Chance For Severe Weather

While it’s all clear in the tropics. There is a chance for severe weather today here in Southeast Louisiana. Some areas could see locally heavy thunder storms. Localized flooding is the biggest risk today. #SELAWX

 

Afternoon Shower Starting Early. Tropics Are All Clear.

 A few showers have popped up. Could see more with some locally heavy. Hopefully they keep things cool and clear out for a nice cool evening. 

Tropics are all clear as we move into an unfavorable MJO phase that has convection suppressed. 

Afternoon Thunderstorms

Afternoon thunderstorms pulling up from the Gulf of Mexico this afternoon. Stay weather aware. Some could produce local street flooding and impaired driving conditions. Stay safe.

It’s Hot Out There!

 It’s hot out there today. Take heat precautions. Drink plenty fluids and take frequent breaks. #SELAWX

Tropical Storm Colin Forms

5am EDT 2 July -- Overnight surface obs, satellite, & radar data indicated Tropical Storm #Colin developed with 40 mph winds. TS Warnings have been issued for parts of the South & North Carolina coasts as the storm moves NE along the shore this weekend.

Here are the latest Spaghetti model plots.

Here is the Radar and Satellite Data

Most of the storms are on the East side of the center. Heavy shear is pushing them off to the East side. But some rain and possibility of flooding can occur. High surf and beach erosion is the biggest threat right now as Colin moves off to the Northeast.
 

Enjoy your Saturday.

New Invest 96L /Texas Invest 95L Is No More / TS Bonnie Making Landfall

 Surprise! Or not. The blob I was watching off the Carolina coast has gotten the attention of the NHC which has now designated it Invest 96L. Nothing more than a blobby rain maker. So, watch out if you're in Georgia and the Carolina's, Flooding rains are a possibility.

Here are the models for Invest 96L

INVEST 95L Is No More

That's right. It's moved ashore and is headed North from the Texas coast. A big sloppy rainmaker for Louisiana, Mississippi and point farther North. 

TS Bonnie Moving Ashore 

TS Bonnie is making land fall down along the Costa Rica/Nicaraguan Eastern coast. Winds 40 MPH and she's moving fast. 20mph. Weak Tropical Storm. Pressure is 1005mb.

Will she remain intact and make the cross over to the Pacific? We will see. So, stay tuned.

Peace Out!
