Potent Plains storm to bring more accumulating snow to Minnesota late Monday

- A very strong storm is developing in the central U.S. which will likely bring more than a foot of rain to parts of the Mississippi River Valley and nearly 3 feet of snow to parts of Texas & New Mexico through the weekend.  This same storm could bring more accumulating snow to the state by late on Monday.

The overall set up for this mess is in the image above...

A LARGE trough is diving into the western U.S. with the polar jet stream in blue diving ALL the way south into Mexico.  It is meeting up with the sub-tropical jet stream in orange which is bringing tropical moisture into the central U.S.  Even more moisture is getting pumped into the Plains via southerly flow out of the Gulf of Mexico.  All of these components are forcing an area of low pressure to develop in west Texas and northern Mexico which will allow heavy rain and snow to develop.  With all of the moisture around, a truly unbelievable amount of rain is likely across parts of the Mississippi River Valley…

A wide swath of 4 to 8 inches of rainfall can be expected from Dallas through Tulsa, St. Louis, and up into Ohio.  Local amounts could easily exceed a foot of rain between now and early next week setting the stage for some wicked flooding over the next couple of weeks.  These thunderstorms will not only produce copious amounts of rain, but a widespread severe weather outbreak is possible across Texas and Oklahoma Saturday which could stretch into the Gulf Coast states on Sunday.  Here are the severe weather outlooks…

Cold air though will be funneling into the back side of this storm and could set the stage for truly unprecedented snowfall in parts of Texas and New Mexico.  Widespread amounts of 1 to 2 feet are possible in the plains of New Mexico and the panhandles of Oklahoma and Texas through Monday, with local areas up to 3 feet.  Combine the record breaking snows with 65 mph winds, and you have the ingredients for a crippling snow event never seen before in that part of the world…

Now the big question for us is where does this storm go???  Well right now that remains unclear.  Upper level winds will detach itself from this storm, cutting it off from the steering current in the atmosphere, allowing it to basically meander wherever it wants to.  Because of this, it makes it far more difficult to predict where it will end up and what it will do.  Right now the thought is it could take one of 3 paths…
