DavisStraight Posted November 4, 2021 Share Posted November 4, 2021 17 minutes ago, ORH_wxman said: You already know this....but for those that don't: Unfortunately very rare in New England....you almost need one of those "due south wind" type events where everything is eroding but someone like Chris up in Greenfield rots at 30F for several hours with ZR and a place like ORH is 40F. But usually those type of events are very transitory....the ZR changes to rain within a few hours. The longer duration ZR events up here all require strong ageostrophic northerly flow and usually that means it's going to be strong through the lower 2000-2500 feet in the atmosphere, so we end up with higher elevations actually doing better until you reach like 2500-3000 feet or so when the temp starts rising again. Was that the set up in 2008? Link to comment Share on other sites More sharing options...

We had some ZR in ORH but a lot of sleet too so it wasn't as icy as just a bit south. Was just texting Ryan about that. I saw some damage on 84 from it.

The synoptic setup was good though...and we even had a mesolow that forms to the east of BOS and went into the gulf of Maine....if the airmass had been like 2-3F colder, then even into metro Boston prob would have had a lot of ice and the 128 belt would have been decimated....and certainly your area to Kevin's too....but both of you missed out by like 0.5-1F....razor thin margin.

You think Lava Rock is losing sleep over Taunton being colder than him? Although maybe he is losing sleep over it? You can bet if he is stealing his snow he is ha ha.

PhineasC Posted November 4, 2021 Share Posted November 4, 2021 A quick drive into Gorham or Berlin during a marginal winter event or upslope period tells me all I need to know about being on the hill or down in a rad pit. I will be 30 with heavy snow and the rad pits are 36 with rain. Happens frequently up here. Link to comment Share on other sites More sharing options...

Not to be overly fastidious ... but, I think it depends also on mass-field orientation. What I mean is, the trajectory angle of the overriding warm column (at its particular given temperature/DP mixing ratio) plays a factor in it's 'erosion' capacitance. A WSW override doesn't need 'as strong' a due N a-geo, to hold cold in. But a due S one, would time the cold retreat/moderation at the surface, inland, faster. Perhaps a key ratio can be derived, ..like, resulting in 1 in the arithmetic; 1.1 results in warm air winning sooner... .9 results in cold air overwhelming and going more pellet ptypes. Pseudo science to make the point - Sufficient influx of DP to offset latent heat of phase change, is in just the right proportion to erosion ( in and out in balance), is all it is needed, and matters less characterizing either side of the boundary as strong or weak, just don't clobber the other side and the icing is static Link to comment Share on other sites More sharing options...

Typhoon Tip Posted November 4, 2021 Share Posted November 4, 2021 2008 ? Yeah, the aspect of that even that stood out to me was how the fringe townships like Acton and Littleton... Maynard ...basically between towns along/asride I-495 that were below the bigger accretion level, lost power for a day or two ...due - it turned out - to compensating grid drag effects. We started blue glow buzzing the night horizons all around us as transformers started domino-ing, shorting out from current reroutes - I thought that was fascinating. As it were, in the morning we had about 1/4" of accretion - interestingly ... - along just the tops of all tree canopies in town, but from mid tree heights to the ground was just damp with no ice. No ice on the car tops or windows, either. That's about as "marginal incarnate" as is imaginably can be demonstrate by an open natural setting.. weird. Never had seen a melt line literally 30 feet off the ground like that. Either way, ... 1/4" isn't enough typically to induce a whole town outage...and we were told that it was drag on the system from the drain.

Here is the loop: http://www.meteo.psu.edu/fxg1/NARR/2008/us1212.php Farther north we had similar 2m temps and precip - rates & total - but accreted maybe 0.25". Must've been a skinnier cold surface layer. In the Jan 1953 ice storm in NNJ that probably triggered my interest in trees and weather, every tall tree near our home at 700' lost branches, often most of them, and a few trees snapped like breaking a pencil. (Noisier, though) In the next town, 2-3 miles north and 300' lower, it was mainly a cold rain. Hilltops above 800' had numerous "asparagus trees", naked stems with the lost branches piled around the base. It was nearly as severe as Jan 1998 though far far smaller in extent, limited to the hilly country N and W from NYC. Link to comment Share on other sites More sharing options...

I think part of it, is due to wind just advecting air that isn't latently rotting at 32.000001F. IOW, get a little off the ground and you'll probably get a nice breeze of 31.5F air, vs near the ground where the air is stale and rotting at 32.000001F. KORH had this phenomenon on roids where the T/TD was maybe 2-3F apart. They weren't in the clouds even in this setup. So you had a 20kt NE wind of like 30/27 or something like that. Just continuously advecting in prime icing air. Link to comment Share on other sites More sharing options...
