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.
Three storms over the next week will dump snow and ice over a large portion of the country, and with frigid arctic air firmly in place around the country, it would appear winter is here to stay.
A bitterly cold air mass is burrowing into the Northwest and northern Rockies today. It will continue to press south and east the rest of the week, only to be slowed trying to reach the East Coast.
Christmas is fast approaching, and the prospect of it being a white Christmas, defined as having an inch of snow on the ground Christmas Day, are growing by the day.
The weather will be quiet in most of the nation on this Thanksgiving Day holiday, a tranquility that will last most of the weekend.
Behind the storm heading up through the East, the atmosphere will quickly quiet down for Thanksgiving, though it will be cold. Most of the nation will enjoy inactive weather most of the four-day weekend.
A powerful storm crossing the Southeast this afternoon will spread flooding rains into the East, with snow on the western flank of the storm. It will be followed by harsh winds and very cold weather heading into the Thanksgiving weekend.
