It has been a decent weekend for snows stretching from North Dakota down through Chicago and into the Mid-Atlantic and even southern Appalachains with some potent lake-effect bands bringing 6-10, locally 12-18 inches of snow to parts of Indiana, Michigan, Ohio, Pennsylvania and Upstate New York but another TWO systems will make an impact tonight into Monday, even Tuesday as the parade of clippers feed down on the northwest upper flow.

While one clipper brings several inches to parts of the interior Mid-Atlantic mountains as well as the interior Northeast, perhaps even bringing a further covering to the Big Cities overnight, yet another streams through Minnesota, southern Wisconsin into Illinois, Indiana and Ohio en-route to the Northeast and Mid-Atlantic tomorrow.

It’s said that Garrett Co, Maryland has picked up nearly a foot of snow from the current system working through.

Here’s the latest GFS snow chart for the next 48 hours.

Note the biggest catch falls in the mountains of West Virginia, perhaps as far south as North Carolina, there are more big pattern changes coming.

A strong Pacific jet is barrelling towards the West Coast, this, like we’ve seen a lot this winter will re-set the ridge-trough pattern across the Lower 48 and while a trough finally gets recarved over the West with potentially the next big winter storm brewing throughout the West, there are question marks above the amount of residual cold over the Midwest and Northeast which may be enough to bring a late week snow storm.

Check this out for late week.

This is for Saturday. A storm system pushing west to east through the Ohio Valley, may bring a further 2-4 inches of snow to the Ohio Valley and Northeast with a possibility of a major winter storm up over New England as the low intensifies off the coast. This would occur right at the point when the ridge is building heights back up over the Midwest and East.

As for the next big storm in the West, models are strong on the idea of a trough recarving over the Four Corners. This would bring a return to much colder weather for cities such as Salt Lake and Denver where January was a tough month. Coldest on record for Salt Lake City, 10th coldest in Elko, Nevada. Salt Lake also reported at least 1 inch of snow on the ground, every day in January.

Here’s the snow chart for next Monday off the GFS, check out the big Western snows extending from the California Sierra through Nevada, Utah, Colorado and even into Kansas and Nebraska where it has over a foot of snow. Also note the deep snows up over New England. Going by this, the milder air never reaches New England, also notice the snow across much of the Northeast, hum.

Here’s the GFS temp anomalies showing a still cold East over the next 48 hours but this cold gets replaced by milder air late this week as the pattern flips. The current warmth over the West will get forced east through the Plaind and eventually into the East as the next storm develops over the Great Basin, in saying this though, the amount of fresh snow over the East will for the first time this winter, really chip away at that warmth heading eastbound and the question is , does it really warm all that much.

Here’s the next 48 hours.

Here’s 0-8 days. No significant warming for the East. If you notice, you can see the cooling in the West with the trough returning but the core of warmth never gets truely into the East, it hangs back over the Plains, perhaps the snow cover is helping chill the air. Notice how warmth gets into the Carolinas and Virginia, where there is NO SNOW lying!

Interestingly, there is a return to cold by day 8-16! This pattern will flip around once again later into next week.. Plenty more winter left yet.

Just look at that 8-16 day, note the next arctic shot dropping into the Midwest, very interesting. Looks like the pattern we’ve just went through is coming right back again.
