We had one heck of a wild week and incredibly, it most certainly appears that more of that comes back next week. Absolutely amazing for this late to see this amount of cold coming down out of Canada and with another strong Pacific system rolling through, you’ve got yet another major snow situation from the Colorado Rockies to Dakotas, Minnesota and into the Great Lakes. Cold records are highly likely to fall as well as snow records too.

Here’s the pressure and precip chart for next week and we’ve got another storm which draws winter-like air down into the Rockies and Plains and out ahead of it, there’s another surge of summer from Texas northeast to the Northeast where NYC climbs back into the 70s, DC the 80s.

Notice by 102 hrs (Wednesday), there’s another low SOUTH of Denver where more cold drives south and with moist winds driving in from the east, you’ve got another snow event in Denver, perhaps bringing another 4-8 inches. This comes once again after highs reach 70 tomorrow but after snows move in and clear through Monday and early Tuesday, the highs will struggle to reach 32 Tuesday pm.

More 30-40 degree departures from normal are on the way for the Rockies and Plains AGAIN Tuesday through Thursday next week…

Check out the 850mb temp profile on Tuesday according to the GFS.

As for snow, here’s the GFS snow projections through 114 hrs.

Notice a decent snow returns to Colorado after a mild to warm weekend coming up. Perhaps 4-8 inches from SE Montana to Northern Minnesota with the low spinning across southern Canada. This low will pull down more of the unusually cold reservoir over the Canadian Prairies. Don’t be surprised if this April turns out coldest on record over this region. No end in sight to the cold and there will be more snow to come following this!!

Notice in the below chart which goes out to 126 hrs there’s a strip of snow appears, trying to get as far south as N Texas and cuts up through western and central Oklahoma, Kansas, Iowa into Wisconsin but as the front slides east the models pep up the snow band. Any snow over the Texas Panhandle becomes more and more significant as time wears on, especially when you’ve got mid-80s for Amarillo, near 90 for Dallas and mid-100s for the Rio Grande on Monday.

Here’s 144 hrs and it’s suggesting a decent snowstorm from Missouri up through Illinois into Michigan with a few inches back down into Oklahoma. It would be quite interesting to see if Oklahoma City can get in on some snow, perhaps an inch or so. VERY significant for this late on down there.

Also note it has 2-4 inches for Springfield, Ill up into Chicago.

More wild times ahead folks and with the NAO projected to go NEGATIVE once again in late April extending into early May, there is NO sign of true spring and the departure of winter for at least the next 2-4 weeks. This could be a record breaker next week for the Northern Plains and one of the greatest late season outbreaks of snow and cold for many many years this late on.

April will turn out cold for much of the United States with a core centred over the Northern Plains extending down into the central Plains but here’s the CFSv2 for May!
