December 28 Weekend rain may include thunderstorms with tornado outbreaks in the Deep South

December 28, 2024

Report Saturday morning

Here is our wet weekend. The good news is that we improved our air quality from the pollution haze yesterday, but we offset that with rain and fog. Within this wet weather we will have some dry hours this weekend as another storm organizes. Temperatures will rise on Sunday and bring heavier rain, with possible thunder on Sunday evening.

Looking ahead to the coming week, another storm will bring rain on New Year’s Eve, followed by only the start of what I expect to be a very cold January pattern.

Surface weather in the morning

The line of rain that moved through overnight will shift to the east and fade to showers. Later it pulses again with more rain.

RISK OF SEVERE STORMS: A tornado outbreak and large hail storms across central Louisiana and Mississippi. These prospects are level 4 out of 5, so don’t be fooled by the ‘Moderate Risk’ category.

This will signal energy input to the second storm… which will swing our way later on Sunday.

There may be scattered showers in the morning, but the bulk of the rain will come in the afternoon through the night.

Thunderstorms are possible, but the severe risk should remain to the south, perhaps cutting off parts of Virginia.

REPEAT MY MESSAGE ABOUT DYSLEXIA

I realize there are some spelling and grammar mistakes and occasional other mistakes. I take responsibility for my mistakes and even the computer errors I may miss. I’ve made a few public statements over the years, but if you’re new here you might have missed it: I am dyslexic and found out during my sophomore year at Cornell University. That didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had come this far without knowing it and not to let it be a crutch going forward. It was Mark Wysocki and he was absolutely right! I miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make matters worse. I can also make mistakes in forecasts. No one is perfect at predicting the future. All maps and information are accurate. The ‘wordy’ stuff can get sticky. There has been no editor to check my work while you write and to have it ready to air in a newsworthy timeline. Barbara Werner is a member of web team which helps me maintain this page. She has taken it upon herself to edit typos when she is free. It could be AFTER you read this. I accept this and maybe prove that what you read is really from me… It’s part of my charm. #FITF
