NEXT FEW HOURS… Scattered showers and thunderstorms will continue to move inland from the Gulf of Mexico. Rain is moving from southwest to northeast, and this general movement is expected to continue. Coverage of rain and storms will likely increase through sunrise. The radar image above is valid as of midnight as we begin the month of December.

SEVERE WEATHER RISK INCREASES… Atmospheric instability will start to increase after sunrise. In addition, winds high in the atmosphere will become more supportive of a few strong to severe storms later this morning. Be ready for a few severe storms and tornado warnings later today!

HAVE A WAY TO GET WARNINGS OVERNIGHT… Scattered showers and thunderstorms will become likely later this (Friday) evening ahead of a round of potentially strong to severe thunderstorms on Saturday. We will likely have two rounds of rain and storms, although I’m not entirely confident that these will be two DISTINCT rounds. While the core of the severe weather risk will likely happen after sunrise on Saturday, there is at least some chance that we could have a tornado warning in our local area before the sun comes up. Thus, we all need to have a way to receive urgent weather warnings BEFORE we go to sleep tonight.

FIRST ROUND OF STORMS… The first round of rain and storms is developing now in the northern Gulf of Mexico. These showers and storms will move into coastal areas first and spread inland overnight. The tornado risk is low with this first wave of storms since instability values aren’t high and atmospheric winds (shear) aren’t screaming, but the risk is NOT zero. If any tornadoes happen overnight, they’re most likely to occur in coastal counties.

HIGHER SEVERE WEATHER RISK AFTER SUNRISE… Severe weather parameters will increase across south Alabama and northwest Florida after the sun rises on Saturday morning. I expect tornado watches will be required. Isolated tornadoes and damaging straight line winds will be the main concerns in any storms that fire up after sunrise.

FLASH FLOOD WATCH… Covington, Walton, Okaloosa, Santa Rosa, and Escambia (FL) counties are under a Flash Flood Watch until Saturday afternoon. Higher rain amounts are likely in these counties that are on the southeast side of our local area. 2-3” of rain is possible in these counties. Lesser rain amounts (1-2” of rain in total) are likely back to the west.

APP ALERTS… Once you have our free RedZone Weather app downloaded on your iOS or Android device, check out the Alerts tab (lower right corner) and tap the large, yellow Alert Settings button to customize the handcrafted alerts you’d like to receive straight from me.

Let me know if you have any weather-related questions. Again, please have a way to receive urgent weather warnings before you go to sleep tonight. Enjoy the evening!

SEVERE STORMS POSSIBLE SATURDAY… Isolated strong to severe thunderstorms capable of producing a few tornadoes and damaging straight line winds will become possible tomorrow (Saturday, December 1) across much of Alabama and northwest Florida. The forecast for our local area remains on track with very little in the way of significant changes to pass along. The Storm Prediction Center (SPC) continues to include the entirety of south Alabama and northwest Florida in their Level 2 (out of 5) “slight risk” zone to potentially see isolated strong to severe thunderstorms on Saturday, particularly in the late morning hours. Isolated tornadoes and damaging straight line winds in the stronger storms will be the main concerns.


SPC continues to include the southern half of Alabama, southeast Mississippi, eastern Louisiana, all of northwest Florida and the Florida Panhandle, and much of southwest Georgia in their Level 2 (out of 5) “slight risk” zone. This zone is basically unchanged since yesterday. Areas included in the slight risk zone will have the highest chance of experiencing severe weather on Saturday. ALL of our local counties are included in this zone.


At the time this update is being produced as of 11:26AM, we have partly to mostly cloudy skies in place across south Alabama and northwest Florida. I expect cloud coverage to increase over the next several hours. There are already a few sprinkles happening across portions of Choctaw, Marengo, and Washington counties in west Alabama. Showers will steadily increase in number across west Alabama through the evening hours.


Most of the high-resolution, short-term models show a complex of rain and thunderstorms developing late this evening into early Saturday morning over the northern Gulf of Mexico. This area of rain and storms will move from southwest to northeast across our area through the early morning hours of Saturday. The big question mark is just how much this area of rain/storms stabalizes the atmosphere. IF significant stabalization occurs, our severe weather risk on Saturday morning/afternoon may be limited. On the contrary, there is a chance that significant stabalization may not occur. This would promote a potential environment for supercell thunderstorm development late on Saturday morning.


The 12 hour window for when severe weather is most likely across our region will be from 4AM to 4PM on Saturday. The core risk will happen late morning into the early afternoon (9AM to 2PM) hours when we have the greatest setup of the “multiple atmospheric ingredients” needed for strong storm formation. The severe weather risk will end from west to east on Saturday. We note most of the storms should be well east of our area by 3PM when many folks will be watching the SEC Championship.


Isolated tornadoes and damaging straight line winds will be the main concerns in the stronger storms. Some weather models are depicting the potential for a few supercell thunderstorms late Saturday morning. Any supercells that become discrete and isolated will have the greatest tornado potential. Definitely something to monitor as we get closer to this potential event. The risk of large hail is low, but not zero. The hail risk will happen in any supercells that can become isolated. Isolated instances of flash flooding may happen, but the overall flash flooding risk remains low.


This will be the final RZW Exec update for this particular severe weather event as our focus will now shift to communicating hazards to the general public. If you have any weather-related decision support questions, please do not hesitate to reach out to me. Have a great weekend!
