Sudden wind fist bashed at the house just now. Let it begin.

1" of water over 1 sq ft is 929 mL, at 20 deg C, 760 torr of atmospheric pressure that would be 929 g or 2.08 lbs. Probably a little more than that for water near 0 deg C. For 1" deep snow, assuming a 10:1 ratio, that's 0.208 lbs/ft^2, more if sleet/wet snow, less if fluff.

On the AN side

Just not the summer of 1988, please.

Thunder heard here about 8:30

Looks like a gravity wave.

Judah hanging on for dear life: "However the MJO is expected to trnasition to five and six over the next two weeks. MJO phases 4-6 favors ridging over eastern North America with mild temperatures and troughing over western North America with cold temperatures. It is not obvious to me that the MJO is influencing North American weather. "

Logan is the one that matters, though, for official records. Looking at Boston Common gives us some hope even in this ratter winter whereas looking at Logan makes one think AGW is taking us to Venus.

GFS low cloud tool has clouds thinning during the evening (when noticeable effects start just after 10 pm) and even out of here near totality. At least there's hope for that.

not the first time that's happened

back to a rain/CFP event?

Huh? SLP over BOS

my bad that was actually 924 in Dec. 2015

Anyone catch that 936 (ouch!) low in the C Pac yesterday (that went into the Aleutians). Something that powerful's gotta have an impact downstream, any guesses what? (Reminds me of the 926 or thereabouts - lowest pressure ever in the Bering Sea - in 2014 and you know what happened after).

especially in this high-shear high-gradient environment. Both have to relax or it's even harder in marginal west ridging situations to get phasing IMO

I really appreciate all the reasoned discussion about MJO and tropical forcing on this forum. I feel it's getting us closer to understanding why this engine of winter won't start

What lat/long (and models of choice) does one typically look at for 850 wind anomalies. If it's equatorial, Seems they're worsening on the GFS but getting better on the Euro

I'm wondering about the Nina-esque performance of the Pacific so far, particularly the W Pac. It seems that unless that firehose jet changes in a big way, we're in as much of a 2011-12 situation as if there were a one-eyed pig over AK. Specifically, the ridiculous persistence of a 210+ kt jet over the western Pacific colocated with that huge wedge of warm SSTs from China to N of Hawaii. There's always a chicken-and-egg question about SSTs driving or being driven by atmospheric circulation, but are they coupled with/ reinforcing each other and drowning out every other signal in the atmosphere?

not during the eclipse, uhpuleeez

Is there some index/prognostication of index that specifically deals with mechanical presence, relaxation or robustness of the flow you're talking about?

Lobsternado.

And in 1988 BOS had only 2.7 or 2.9" or something like that by 1/31. A record futility for the date at that time of course that was 1988, so maybe bad example

Just like the models are. They're reeling like the PV
