Give No Quarter

Posted by Pete Bouchard

Big slop-fest out there this afternoon/evening. After 6-12 inches of snow in Greater Boston and Worcester - and lesser amounts south of the Pike, it's time to clean up and move on...again.

I think we've passed the point of tolerance with these ceaseless storms. Gone are the days when viewers would flood our inboxes with pretty pictures of their pets and kids frolicing in the snow. Constant cleanup has made us snippy and short - even a few plow guys have hoisted the white flag. The holidays are long past, the winter is stale, and the people just want spring...

...and accountability.  Instead of pictures, I get questions in my inbox. "Why are we getting so much snow? Why did it turn on a dime? And when will it stop?"

Those are fair questions. But with the limits of the long range (10-14 day) forecasts, I'm not ready to answer the last question. We may sail out of this in April, but so far the first week of the month isn't looking much different from the first week in March. The ultimate question is why.

The jetstream has taken on an odd path.

The black lines represent the jetstream (wind moving from west to east). The colored areas represent the departure from the normal position of the jetstream. The bullseye is apparent: right over Nunavut (Northern Canada). High pressure has dominated this area since early February, diverting the cold and the jetstream over the Lower 48.

So there you have it. The culprit, the scapegoat, the reason for over 100" of snow in Worcester, and the reason I can't talk about 70s and 80s like last March. But the bigger question is, why does it last so long.

Ocean/atmosphere interaction is still a young branch of the science of meteorology. There are many reasons for stalled weather patterns, but I believe the biggest is the lack of sea ice from climate change. An open ocean leaves a lot of heat in the poles. This fosters high pressure (or blocks in the jetstream), and with very little movement to weather patterns at the top and bottom of the globe, we get pinned down in these long periods of heavy precipitation/drought and hot or cold.

An undeniable link in the cog has been established. And we're left to wait it out.

50/50 Weekend

Posted by Chris Lambert

We're off to an iffy start to the weekend as nuisance rain and wet snow moves across the area.  While it's not a well organized area of low pressure, it develops right near us midday, and that'll be enough for a tricky forecast.  Light to moderate  rain/snow is on and off early this morning with a heavier burst of precipitation possible late morning, through mid afternoon in eastern MA (11:00AM-3:00PM).

Final Days

Posted by Pete Bouchard

That's the way to get it done! Fine finish to the workweek as sun dominated and winds behaved.

I submit that is the one - and perhaps only - reason these days have felt springlike in this extended thaw. If the winds were gusty on a day like today, the sun (albeit a little stronger these days) is really no help.

Great Mid-Winter Weather

Posted by Jeremy Reiner

Nice mid-winter weather? Here's how I envision it:

*Sunshine

*Mild temps (40 or higher)

*Little to no wind

That last bullet point (IMO) is probably the biggest when outside this time of year. After our morning fog lifts out of here all three of those criteria will be met this afternoon AND.....it's Friday. #Winning.

Colder Temperatures Cometh

Posted by Pete Bouchard

As far as blah days go, this was the blahest.

Fog blanketed the area as winds remained light and variable. We're still looking at some fog, but the thickest part of it should only be during the first half of the night. After that, gentle winds should "mix out" some of the heavily fogged in areas.
