Record tying low temperatures in parts of the Southeast U.S. the past couple of mornings according to the National Weather Service, but big change is ahead.

Last Sunday was mostly cloudy windy and cold with temperatures well below normal for May with a high of only 66. The normal high for this time of year is 80.

Temperatures will moderate in dry air the next couple days, and temperatures turn around significantly by Friday with a reversal from autumn chill to poolside weather on the weekend.

Readings will be near the 90 mark with modest humidity and a decent dose of sunshine, south Georgia is looking like 95! This is quite a contrast to last weekend when people were in sweaters and jackets and dressing in layers at the kids baseball and soccer games.

 Readings will be 24 degrees above last Sundays maximum.

The European model is showing 95 in Atlanta Monday through Wednesday with 100 in southeast Georgia. Seems too extreme to me but you can see the trend.

This is yet another yo-yo temperature period just as was predicted to occur for this spring in the long-range outlook. Interesting that the latest thermometer extreme swings are occurring near the Full Moon. I've posted before on how major weather pattern changes often coincide about 4 days either side of the Full Moon.

This week a big cold pool of air aloft, a swirling vortex of low pressure at the jet stream level brought the chill and the clouds and the few showers as the "bowling ball" closed upper-air low moved over the Southeast USA. It will be lifting Northeast away from us, replaced by a ridge of high pressure bringing back the warm air as an "Omega Block" jet stream pattern covers the country.

This kind of pattern is stable and for us only a stray pop-up late day thundershower is possible Sunday through Wednesday with summer-like temperatures continuing.
