Spring often brings out some of the wildest weather, and the rest of this week the weather will be just that - wild. To give you an idea of how wild it already is, just look at the changes from yesterday to today across Colorado and western Nebraska. Look at the highs Monday:
Today, much of eastern Colorado is either in the teens or low 20s, as is the case in western Kansas and western Nebraska. And that's without the wind! When you factor in the wind, it feels like its either at or below zero. Effectively, a 70-degree temperature swing. And then, of course, there is the snow.
There will be more snow in the coming days. The latest updated AccuWeather.com snowfall projections through tomorrow:
Snow is also possible, believe it or not, in extreme upstate New York and New England from the storm, though most areas will get rain, even if it is a cold rain.
Severe weather to this point has been, thankfully, pretty spotty. What there was on Monday, though, was concentrated near the boundary between the warmth and the impending chill. Look at the severe weather reports from Monday and Monday night:
There will be more severe thunderstorms this afternoon and tonight, stretching from central Texas all the way to southern Iowa and Illinois. There have already been a few hail-bearing thunderstorms in north-central Illinois this morning, even with surface temperatures in the 40s and lower 50s! The rest of the day and night will be fairly active, too, especially with such a sharp contrast from one side of the front to the other.
Tomorrow and tomorrow night, everything will be shifted east, with the severe weather threat running from East Texas up into Missouri and Illinois, inching eastward at night, and impacting areas from the lower Mississippi Valley into the Deep South late tomorrow night and Thursday, as well as the Tennessee Valley and Ohio Valley. That, of course, includes large hail, destructive winds and possibly tornadoes.
Lastly, the rain. The NAM tends to overestimate precipitation, but from this graphic, you can get the idea that there will be a lot of places dealing with 1-2 inches of rain in the next 72 hours or so, and some more than 3 inches:
Thankfully, as the storm begins to speed up on Friday, the heaviest of the rain will diminish, the severe weather will lessen and the intensity of the cold will also start to back down. That will set the stage for a much more tame weekend.
Two systems will delay the onset of warm weather in the Ohio Valley and the East over the next week or so, but then it should get warm all across the country heading into the Memorial Day weekend.
A turn to much colder air over the Northeast and mid-Atlantic states will set the stage for a rain and snow storm later this weekend before it turns much warmer later next week.
It's warm now, but will turn much colder this weekend, with a storm threat later Saturday into Sunday. Warmth will return by the second half of next week.
Though it is cold now east of the Mississippi, with a couple of opportunities for snow into the weekend, a blast of warmth is due for much of the country east of the Rockies next week.
Warm air will once again surge eastward from the Plains to the East Coast this weekend and early next week. A strong storm next Tuesday and Wednesday will then be followed by colder air later next week.
A storm in Southeast Texas will generate severe thunderstorms this afternoon and tonight, and some wet snow on its western flank as it heads into the Ohio Valley tomorrow.
