Dwindling Snowpack; East Coast Crippling Blizzard

Dwindling Snowpack
I stepped outside on Sunday and was struck by the lack of snow on the ground in my yard. There sure are a lot of bare spots out there, especially since it's still January! There was 1" of snow on the ground (officially) at the Minneapolis Airport on Sunday morning. At this time last year, there was 13" of snow on the ground! Interestingly, there was no snow on the ground (officially) on January 26th, 2013.



Hype-Worthy Storm
By Paul Douglas

Here's a poorly guarded secret. Meteorologists tend to hype storms. Why? Well, it makes us feel important - and it gives us something to point to on our colorful maps. And (most) people are more forgiving if there's less snow than predicted. God help you if you predict a dusting and the town wakes up to a foot of flurries. That's the original meteorological sin. Sadly, if you added up all the PREDICTED snow over the years we'd be tunneling out from under another ice age by now.

14 of the 15 warmest years on record have been observed since 2000. An estimated 93 percent of the extra warmth is going into the world's oceans. Gulf stream water east of New Jersey is 10-15F warmer than normal for late January, adding fuel to an historic blizzard winding up from New York to Boston. 1-3 feet of snow, 50 mph winds, 5 to 10 foot drifts, power outages and coastal flooding; this will be an epic storm.

While we stare out at brown lawns and dripping icicles: 40s into midweek, then 30 degrees colder Super Bowl Sunday. But mild, Pacific air dominates into early February.

The last time we saw 40s in January? 2012. That was the year flowers were blooming by late March. Will history repeat?

Minneapolis Temperature Trend
Weather conditions close to home will stay on the mild side over the next several days. In fact, temperatures may sneak up into the 40s a couple of times this week! We're still getting indications of a bigger cool down by the end of the week/weekend...



Monday Weather Outlook
Temperatures on Monday will be a little warmer than Sunday. Readings will get back to near 40F in the Twin Cities with a few locations in southwest MN nearing 50F! A slight breeze will make it feel a little cooler (image on right).



Monday Weather Outlook
Another clipper system will slide through the region late Sunday through Monday. The best chance of snow accumulations will be across the Arrowhead of Minnesota and into northern Wisconsin.



Another Day Another Clipper
Another fast moving clipper is set to move through the region late Sunday/Monday with a light wintry mix and a light snow accumulation. The best chance for snow accumulations would be across the Arrowhead of Minnesota and northern Wisconsin.



Clipper Snow Potential
Here's a look the snow potential through early next week... There may be some light shoveling duties across the Arrowhead and northern Wisconsin. The Twin Cities looks to miss out on anything substantial.



National Weather Outlook
The clipper system that missed us (Twin Cities) on Saturday night/early Sunday is set to become a major winter storm on the East Coast! Watch how the system transitions from a clipper to a full blown mature storm in the Northeast.



National Weather Outlook
Here's another animation of the storm system that will be rapidly intensifying near the Northern New England States.



Northeast Snowfall
The accumulating snow potential turns from a shovelable event to a crippling event as the storm curls northeast towards the Northern New England States. There's a fairly large swath of 1ft to nearly 2ft. from Long Island, NY to northern Maine!



Winter Weather Headlines
There are a number of winter weather headlines that have been issued from the Ohio Valley to the Northern New England States. Note the strip of red (blizzard warnings) that have been issued from eastern New Jersey to eastern Maine... The blizzard warning includes New York and Boston!



Blizzard Potential Index
Here's a look at the Blizzard Potential Index... It takes a look at the blizzard criteria (snow and winds of 35mph for at least 3 hours) and puts it into a color scheme. Anything that is orange/red is quite impressive. Note that these colors become more intense over Long Island to Boston to Maine... it could get pretty interesting!



BPI: Hour by Hour
Here's what the Blizzard Potential Index looks like hour by hour...



Boston: Calm Before the Storm...
This was the view from Boston Colleges' O'Neill Plaza from Sunday afternoon. This was after the 5.1" that fell (officially) in Boston on Saturday... Weather conditions will sour through the day on Monday with the worst of the upcoming winter storm heading in Monday Night/Tuesday.

Take a look at the latest LIVE webcam from Boston College HERE:



Boston Snow Potential

NYC Snow Potential
2ft to 3ft?? According to the NWS out of New York, this is the 'most likely scenario' - YIKES!!

Blizzard Potential for the Northeast Remains High!
Here's a look at what folks along the Eastern Seaboard could be dealing with late Monday/early Tuesday... At this time, the center of the storm is expected to be offshore (just south of Cape Cod). This will help to keep temperatures colder inland and likely in the form of snow. Note the lines of equal air pressure (black lines) - due to a VERY tight pressure gradient, the winds are expected to be quite extreme with some wind gusts up to 60mph! Heavy snow and strong winds will create blizzard conditions for a large area!



Significant Winds
As the storm system intensifies offshore, wind speeds will begin to increase significantly. Note that by 10am Tuesday, winds along the coast could be gusting upwards of 40mph to 60mph! With heavy snow and strong winds, blizzard conditions will be a major concern!
