Our Northern Hemisphere Atmospheric Traffic Jam is Easing up a bit.
Instead of bumper to bumper upper lows crawling along at snails pace,
we now see systems opening up to tortoise pace. The track is changing a
bit too. Tonight, Sunday May 22, 2011 we have a severe weather watch
from Mexico to Canada, most of which is for tornadoes. This massive
storm will lift to our north Tuesday, with some of the warmest air of
the season arriving for a day or so.
This storm dropped 37" of snow at Alta Utah this week (bringing
season total to near 750"). Snow also fell in Colorado again. One life
was lost in a Summit County Avalanche on Saturday May 21st. On the east
side of the storm the tornado count is near 50 for the last few days,
as the severe storm season kicks back up. Here is the map showing watches and warnings tonight.
In New England we are still feeling effects from the 8 day upper low,
that deposited 1"-5" of rain here in the last 8 consecutive days, today
is the first day with no downpours since Friday May13th.
This coming week we have fewer downpours, but we may have them each
day, except perhaps Thursday. As the next storm tracks into Ontario, we
get a warm front with many clouds and a few showers Monday. Then the
cold front will weaken into a decaying front for early Tuesday, with
sun & a storm and highs near 80. The we get a reinforcing front
Tuesday Night, with a wave on said front Wednesday. The south wind
Tuesday is warm, the light north wind Wednesday is seasonable. The next
weather system actually moves in Quickly (weather systems speeding up a
bit) Thursday Night and Friday. That means we should warm back up to
near or above 70° Thursday and Friday. Thursday looks like the pick of
the week, with no storms forecast (for now). By Friday the weather
pattern starts to bog down again, The front in New York pushes warmer
air in Friday, but clouds and storms may take the fun out that day
(unless you like storms). By our Memorial Day Weekend we have some
trouble. Another Upper Low will stall near the Appalachians with the
possibility for some extreme weather in the eastern United States. The
reason I say extreme is due to Tropical air surging from The Bahamas
toward New England, at the same time Record cold air attacks from
Canada into The Great Lakes region. The best we can hope for is that
the front stays far enough west that we have warm humid air and
scattered storms. The worst case scenario is a front stalled south of
us with a cold wind from the north, as tropical rides over the top with
over running rains and possible flooding.
From the Surf/ski department, our old upper low from last week is
stalling south of Bermuda with a new extra tropical circulation wayyy
out there.. maybe a tiny groundswell at the south coast? It's a stretch.
And Arapahoe Basin in Colorado has 23" of new snow this week, and will be open weekends in June.
We also have enough snow for a few turns left at Tuckerman's Ravine in New Hampshire.
