Clipper flipper...

Saturday Night: Rain or snow likely. Lows in the lower 30s. Chance of precipitation 60 percent.

A LIGHT SNOW

ACCUMULATION OF A DUSTING TO SEVERAL INCHES LOOKS LIKELY ABOVE

1500 FT BY SUNDAY...ESPECIALLY WHERE LAKE MOISTURE AND CLIPPER

DYNAMICS/LIFT COMBINED TO PRODUCE SLIGHTLY HIGHER QPF AMOUNTS.

Fascinating... I was just checking the 1921 ice-storm out over at the NCEP library and what started out as a classic icing weather pattern, featuring a polar high retreating N (not E) and waves of LPs passing near LI, eventually evolved into an intense coastal storm that passed SE of CC.  I am trying to find annals that write more details event profiling, ... because big ice doesn't normally come from CCB's 

 

  ..how odd ..

 

Edit: here's a good run-down of the event:  http://www.the-electric-orphanage.org/great-storms-and-their-aftermath/

The zfp doesn't mention it but the PnC mentions snow for here as well - first time that's been mentioned.

 

  • Saturday Night A chance of rain and snow showers. Mostly cloudy, with a low around 35. Chance of precipitation is 30%.
  • Sunday A chance of rain and snow showers. Partly sunny, with a high near 51. Chance of precipitation is 30%.

yes but 4.05 melted equivalent, wow, Concord Mass, 

 

Oh yeah tons of QPF, but the setup seems similar.  High to the north, overrunning from low pressure and stalled front. Low elevations of NE  MA hit. Not much in CT away from MA border.

There are going to be some nice squalls in the next week coming off the GL, probably spill overs into the usual spots. Should be pretty wintry at times in NNE

Well, now that the colder air is moving in, we won't be setting any monthly records....but, the period of October 1st through the 20th was the 2nd warmest on record in 120 years at BTV (+7.2 departure). Only 1947 saw a warmer first three weeks of October. Impressive period.

One of my favorite ice storms pics is a November Ice storm. Tufts University November 1936

That's impressive for Somerville. Pretty much the city

Even more so for Medford...lol

Dropping fast tonight.  38/36

 

Box with flakes in the forecast even for the Valley this w/e.

 

Nice pattern change to ease us into Winter.

 

Funny, there are no freeze warnings here because growing season is considered officially over yet most of the farms, even in the hill towns, were still cranking this week due to the mild October. Still native corn coming in although that will end quickly.

Was just checking temps at midnight for snowmaking, and the pesky mid-elevation warm layer and inversion will make it not possible tonight. Hopefully once we get into the -6C to -8C range at H85 it will overcome that mild layer.

This happens like clockwork this time of year...warm dry adiabatic from 4000-1500ft, then the cold pools below that level. Really makes it hard to make snow near the base area unless we are drilling -10C or something over the top...

Current thermal profile at midnight:

4000ft...28F (MMNV1)

2500ft...35F

1600ft...40F (Mansfield base)

750ft...33F (Stowe village)

300ft...43F (BTV, for comparison)

Here's the Mansfield profile from BTV...including BTV airport's 43F as the lowest level value...the west and east slopes near 700-1000ft are all near freezing. But check out that inversion...drives me nuts during snowmaking season, lol.
