The system which had all the signs of being a biggy, was just that. The system as expected dove into the Four Corners where it drew on moisture warm, moist air from a warmer than normal Gulf. As a result, coupled with tremendous orographic lift, 1-4ft of snow fell from Denver up into the high country.

While upwards of 12 inches is a decent snowstorm for Denver, this didn’t fall within the top 5 biggest April snowstorms.

The latest visible and infrared loop shows beautifully the low swirling over Colorado while energy being drawn in along the frontal boundary, flared tremendous convection. The front can be depicted from the N-S sharp line of darker cloud stretching from southeast Wyoming to the Texas-Mexico border.

This major snow system is now lifting up over the western high Plains but to the SW, it’s not the snow but record heat that’s the weather talk.

Notice how there’s just a small area of cool surrounded by a sea of spring warmth across the nation today.

While the system was dropping snow on Colorado, it was bringing severe weather further east over Kansas down into Texas. Tornado, damaging wind and very large hail accompanied the flooding rains.

More of the same expected today.

The GFS 500mb height anomaly for today shows the cut off low and small area of cold within a sea of warm ridging covering the country.

This negative persists, remaining stuck but slowly migrating north up into the N Rockies and Plains through the forthcoming work week.

As you can see, by mid week, a weak trough grazes the Northeast US as heights build northward.

Then towards late week, below normal heights begin to push south from Hudson Bay while the lost cut off rotates back S and E through the Lower MS Valley and Southeast.

As of now anyway, long way to go… but the model only grazes New England with the deeper trough trying to drop out of Canada into the Northeast. Heights begin to build back west and I recon depending upon how much the ridge builds and how far east will determine how much of a trough we see over New England, Northeast or perhaps just eastern Canada next weekend.

The upper setup is beginning to shift more towards a spring look.
