Bridgeport, CT: 9th snowiest March so far

only 8.1 inches so far this month, Nor'easters keep skimming me. Or I get dry slots. Guessing 2000' in southern Vermont near the MA border may have gotten most snow this month

I love all 3 but if I had to pick Id choose the Fir or Spruce. We been losing so many Pines here recent yrs. Between the October 2011 snowstorm, the hurricane salt burn, the wind storms, the drought, and now the March snowstorm they been slowly disappearing/thinning and nobody is replanting them because they are weak.

That's Oklahoma from late November to the end of February. At least in North Carolina there are lots of evergreens.

The extreme precipitation amounts with heavy wet snow don’t help matters, but they do very well in northern New England. I think if you do consistent pruning of lower branches it lessens burden for extreme events. Most of NH is white pine, 6-8 year cone cycle usually produces new trees on well managed forests.

Southeast shivers overnight after exceptional warmth in the Plains; Canadian high halts warmth

Currently 16.7°C (Normal Low 12.2°C)

Forecast High is 21.7°C (Normal High 25°C)

Go ahead....look for it.... Find me more than 3 days in a row without any precip falling.

(Hint... It's been since December!)

And with the snow squalls yesterday it makes it 3 days in a row with snow falling and the 9th day this month with snow falling.


12.54" precip in last 9 weeks.

Yikes.

Nice discussion from them but lets count how many times they say "polar"

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Models in general agreement with the large scale CONUS omega
blocking pattern mid week, gradually breaking down heading into the
weekend. The stubborn SE Canadian upper low of this week will
gradually weaken and lift towards Greenland this weekend, replaced
by a quick moving but intense polar low. Meanwhile a closed upper
low currently over the PAC gradually gets caught up in the southern
stream and rolls its way across the country this weekend. This
energy will eventually facilitate phasing between the northern and
southern stream into the Eastern US early to mid next week. There is
good model agreement in resultant deep Eastern US troughing
development by mid week, but quite a bit of model spread in the
timing, intensity and track of the closed upper low anchoring this
trough.

SBU CSTAR ensemble sensitivity analysis is keying in on the
evolution of the NW US closed upper low, but more so the downstream
effects of a strong closed, cutoff low developing south of the
Aleutians and dominating the eastern PAC this weekend. It appears
that shortwave energy (wavepacket) emanating from this Aleutian/E
Pac low is the forcing for N/S stream phasing and development of a
coastal low during the Mon Night into Wed Night time frame.
Significant model spread in this time period is lending to a low
confidence forecast on the timing, track and intensity of coastal
low pressure/s Monday night into Wednesday Night. The signal has
been consistent for a period or periods of precip with a complex low
pressure system during Mon Night into Wed Night, but details on
precip type and amounts, strength and duration of winds, and other
sensible hazards is low at this time. Monitor subsequent forecasts
through the weekend as the energies and interactions above become
better resolved by NWP.

Before then a relatively tranquil, fair and below seasonable temp
pattern for the region Friday Night into Monday in between streams
of a split upper flow. A strong polar low swings through Northern
England this weekend, sending a polar front through the region late
Saturday. Meanwhile, appears shortwave energy that pivots around the
base of the Western US closed low today, will remain riding along
the southern stream. This will have a quick moving southern low
tracking well south of the region this weekend. Will have to watch
for any interaction between these streams to ride this low further
north, but unlikely at this point. Primary uncertainty during this
time period is magnitude of polar air that sinks south into the
region Saturday Night into Sunday, as there is model spread on this.
Temps could be a few degrees cooler than forecast if the polar low
sinks a bit further south

49f here. Wind blowing off the gulf keeps me 8 degrees warmer than just 3 miles inland
