4th of July 4Cast; Extreme Florida Flooding

Thursday, July 4th, 2013

Happy 4th of July! Whether you’re enjoying time with family, friends and just hanging out… thanks for checking in! Weather conditions across the nation, for the most part, look fairly decent. There is one caveat, though, as heavy rain and thunder are expected to make for a not-so-nice 4th from the Gulf Coast of the Florida Panhandle to the Ohio Valley and Eastern Great Lakes.

Fireworks Forecast

Do you have plans to catch any fireworks displays this evening? The image below shows where some of the best/worst viewing will take place tonight.

Weather Setup

A stubborn upper level low pressure system over the Middle Mississippi Valley and a stationary Bermuda High are working in tandem to draw in copious amounts of tropical moisture across parts of the Southeast.

4th Rainfall Potential

According to NOAA’s HPC rainfall forecast for today, there could be 1″ to 3″ of rainfall possible in that narrow swath mentioned above. This is on top of an already saturated ground, so additional flooding certainly can’t be ruled out! Also note a few spotty areas of rainfall accumulation in the west, where isolated (monsoonal) thunderstorms will blossom during the afternoon/evening hours.

4th 4Cast High Temps

Here’s a look at some appropriately named cities and their forecast high temps for the day today.

Extreme Heat

As many people plan their day ahead, keep in mind that some of the heat out there may be a little excessive. The National Weather Service has issued HEAT ADVISORIES and EXCESSIVE HEAT WARNINGS for a few locations today.

Heat Safety Tips

Just a reminder… Here are some heat safety tips as you enjoy your 4th of July!

Significant Southeast Rainfall

We’ve already received several reports of flooding in the Southeast thanks to all the recent heavy rain, but there’s more on the way! Thanks to Whitney Day Fowle for the flooding picture below out of Bonifay, FL

Past 7 Day Rainfall

According to NWS radar rain estimates, some spots have see 5″ to 8″+ rainfall over the past 7 days. Keep in mind that the ground is already saturated in many spots, so additional heavy rainfall could lead to more flash flooding!

Additional Heavy Rainfall

According to NOAA’s HPC 5 day rainfall forecast, there could be an additional 3″ to 6″ (Isolated 6″ to 12″+) of rainfall through early next week. Flooding could be a serious concern over the next few days. Keep that in mind if you’re traveling for the long holiday weekend, especially if you come to flooded roadways/etc. Monsoon thunderstorm could also bring flash flooding concerns to parts of the Southwest over the coming days.
