RARE LEVEL 4 RISK FOR OKLAHOMA… No severe weather issues are expected today or over the next few days across Alabama or northwest Florida. We do note, however, that the Storm Prediction Center has just issued a special convective outlook upgrade for much of eastern Oklahoma where a Level 4 (out of 5) risk is now in place. Numerous tornado warnings are happening there.
Severe thunderstorms will occur across parts of the southern Plains northeastward into Illinois/Indiana today and tonight. This includes a risk for tornadoes, large hail, and locally damaging gusts. The greatest risk is from north Texas through Oklahoma into southwest Missouri pic.twitter.com/4Eha3mGZpq

SUNNY & WARM TODAY; FEW SHOWERS POSSIBLE WEDNESDAY… Today very well may be the warmest day of the year so far for many spots across south Alabama and northwest Florida. High temperatures will rise into the upper-80s by 3PM. Some spots may eclipse the 90 degree mark. Other than a few passing high clouds and maybe a few puffy, white cumulus clouds this afternoon, today should be mostly sunny. We could have a few showers around in the afternoon hours of Wednesday ahead of slightly higher rain chances for the end of the week. The good news is that severe weather parameters remain very low over the next 7 days. Let’s look at a few forecast details…
WEDNESDAY P.M. SHOWERS & STORMS… Tomorrow will be similar to how our typical summertime weather pattern is, in that we could have pop-up showers and thunderstorms in place across south Alabama and northwest Florida, particularly after 1PM. We’ll call it a 20-30% chance of rain, meaning MOST of us should remain dry and warm throughout the day on Wednesday. High temperatures will peak around 88°.
MORE SHOWERS POSSIBLE THURSDAY INTO FRIDAY… While an “all day washout” event is not expected on Thursday or Friday, we could have a few spotty showers around. Keep the rain gear handy. There could be a few thunderstorms involved in the afternoon hours each day. Severe weather, however, is not expected. High temperatures will be in the upper-80s with morning lows in the mid-60s.
See all the graphics and details in your Tuesday #rzw forecast video… Have a great day!
Partly cloudy skies are expected on this Tuesday… High temperatures will peak in the mid- to upper-80s on this last day of April. Feeling more like summer today compared to the last few days! pic.twitter.com/hDVgSwehLB

USGS CONFIRMS BOOM WAS NOT AN EARTHQUAKE… The startling sonic boom and minor shaking experienced by thousands of people this morning across parts of central Escambia (AL) and southern Conecuh counties in south Alabama was NOT caused by an earthquake. I just received a call back from the U.S. Geological Survey. After geophysicists reviewed the seismology data AND your Facebook comments in my initial post this morning, the USGS says this was a sonic boom/shockwave event that could have been caused by low-flying military aircraft.
Thanks to each person who commented about their experience in the initial post here. It is always helpful to have “ground truth” reports for weather-related and non-weather-related events like this!
