As we’ve expected over the last several days, it’s lining up perfectly for a heavy rain event across much of the Southeast US today from the Mississippi Valley to the Carolina coast. Heaviest rains will be along the Gulf Coast, Georgia, into the Appalachians, Tennessee and Ohio Valleys. There is a marginal to slight risk for severe thunderstorms, with wind damage being the only threat this time, but by far too much rain, too fast will be the biggest problem today and tonight.
As low pressure over Missouri and Illinois continues to wind up and head towards the northeast, it’s leaving the Gulf of Mexico WIDE OPEN for business. Hence the heavy rain and possible flooding threat. Mobile, Tallahassee, Montgomery, Birmingham, Atlanta, Chattanooga, Greenville, Charlotte and Roanoke are the metro areas at greatest risk. Stay weather aware, have multiple ways to get warnings, and TURN AROUND, DON’T DROWN.
Tomorrow the storm lifts into the eastern Great Lakes, the Mid-Atlantic and the Northeast. This again, will continue to be a very wet storm with high rainfall totals spreading up into RVA, DC, Baltimore, Philly, the NYC area, and up to as far north as Scranton and Binghamton. Heavy rains with embedded thunderstorms capable of minor wind damage will be the story tomorrow for the above metro areas. It gradually dries out across the Southeast, the Tennessee, Mississippi and Ohio Valleys. If you are in the Mid-Atlantic and/or the Northeast and you are heading out camping on Friday… good luck! And stay dry.
On Saturday the rain and thunderstorms begin to weaken as the storm pulls farther away from the Gulf of Mexico. There will be wet weather across most of the Northeast, especially in the morning from Pittsburgh to Buffalo, Syracuse, Albany, NYC, and most of New England. In eastern NY, New England and the NYC area, the rain and thunderstorms will last much of the day so be prepared for Saturday to be not a good day to be outside, out and about. Not a good lake or camping day yet again.
Sunday and Memorial Day will both be exceptionally nice days across the entire eastern US from the Mississippi Valley eastbound all the way to the coast. All areas will see the rains and thunderstorms end, and Sunday’s temps look fabulous, with most of the eastern US in the 70s and 80s for afternoon highs. Levels of humidity will be comfortable, it will not be overly oppressive. Same thing for Memorial Day. This Memorial Day 2022, will be a gorgeous day with lots of sun, comfortable levels of humidity, and just a plain old 10/10 on the weather scale. Get out and enjoy it weather. Weather will have little to no impact on remembrance services and parades.
The pattern continues to warm up, humidity gradually increases middle to end of next week over the eastern 1/2 of the nation with above normal temperatures and below normal precipitation expected, especially across the Great Lakes, Mid-Atlantic and the Northeast. One place I have spent no time talking about this whole blog is the Pacific NW, northern Rockies and the northern Plains. Here, it’s not going to be ice cold and terrible, but it won’t be sunny and hot either. Expect cooler than normal temperatures really from now into the beginning of June. Best chances of seeing rain showers, will be in the afternoon and evening. Not every day will see it. Not everyday will be wet or a washout, but the weather will remain unsettled for some time in this region of the country. Again, buying time before summer sun and heat begins to bake this area of the nation and drives the wildfire danger sky high.
