wxeyeNH Posted March 6, 2011 Share Posted March 6, 2011 6pm 35F light rain . Just spoke to a friend in Groton NH at 1500 feet and she says its pinging!. Groton is one town west of Plymouth NH Link to comment Share on other sites More sharing options...
dendrite Posted March 6, 2011 Share Posted March 6, 2011 This suggests sleet is very possible. I mean it's so borderline. If the precip is heavy though... IDK. Going to be wait and see. HYSPLIT? Isn't that lagrangian?Anyways...when I said it's borderline I did look at the 825mb GFS temps...they're similar to 800mb. I know verbatim you're safe, but my point was just that if it verifies a little warmer it could make a huge difference. The front is through here. I can hear the +RA hitting the north side windows.

CoastalWx Posted March 6, 2011 Share Posted March 6, 2011 There could be a pretty good ping zone near and nw of Brian tonight. As the low develops along the front, WAA should get going, which will limit the southward progression of the cooler air at 850 and 800mb. The surface front should still sink south.

Although I'll take mostly sleet if I can pull off a miracle of 3"+ of snow on top. 38.4F Still the strangest thing I ever had was two 3+ inch sleet storms within a month of each other back in NYC '07. Never really experienced an "ice" storm. Well not in the last 17 years anyway. Link to comment Share on other sites More sharing options...
ApacheTrout Posted March 6, 2011 Share Posted March 6, 2011 Received 0.75 inches of rain today, and then the rain switched over to snow at 1:00 pm. There's 4 inches of new snow on the ground. I'm wondering if this part of Vermont is on its way to 20 inches of snow overnight. Vermont is stubbornly refusing to let go of winter and head into mud season. I suspect there'll be more than a few sugar makers repairing down sap lines tomorrow. Link to comment Share on other sites More sharing options...

There might be a thin band of really bad icing if the icing conditions can stay relatively stationary for about 8-10 hours. Duration is the key though...even if its coming down heavy, "only" 4-6 hours won't do it for horrible icing...probably would be getting bad, but not more than 3 or 4 tenths of accretion.

Allenson Posted March 6, 2011 Share Posted March 6, 2011 Who works for the college? Staff, prof, administration? Allenson works here, and we've met up. Present! Still 32F here--hasn't dropped any in a while. Snow falling. About 1/2" so far. Wet & sticky snow, but snow still. Regarding the temp fluctuations folks are seeing--same thing happened here before the front. 44, then 45, then 43 back up to 45, etc., etc. 45F was the tops here today...

simpsonsbuff Posted March 6, 2011 Share Posted March 6, 2011 Darn it still rain here. Stupid Lebanon. I'm waiting! haha Sorta flipping back. I was out and it was sleet/rain. Now it's kinda a white rain (i.e. huge rain drops) and a little sleet. Link to comment Share on other sites More sharing options...

Yeah it might be very thin, but significant....perhaps close to Brian or just to his nw..lol. The terrain is probably going to cause lots of mesoscale craziness with the winds draining north. Sometimes those n-s valleys up there are good at draining the cold south, through the Whites. Link to comment Share on other sites More sharing options...

dendrite Posted March 6, 2011 Share Posted March 6, 2011 Present! Still 32F here--hasn't dropped any in a while. Sometimes the temp drop gets hung up around 32F for a bit while everything freezes up. All of the rain from earlier freezing releases some latent heat. Link to comment Share on other sites More sharing options...

Other thing is that we'll need temps solidly below freezing to actually get accretion during the heavy rainfall rates. We'll see what happens, but '08 was a unique situation that was able to pull this off. Link to comment Share on other sites More sharing options...

VtWeatherWatcher Posted March 6, 2011 Share Posted March 6, 2011 +SN here @ 27F, 2" of accum so far. Trees are all plastered already. The Mad River jammed up pretty good today. Impressive ice flow up to the guardrail on 100B just south of Middlesex. Apparently it did come over the road further south towards town... AT 1259 PM EST...LAW ENFORCEMENT REPORTS AN ICE JAM ON THE MAD RIVER NEAR MORETOWN HAS RESULTED IN THE RIVER GOING OVER BANKFULL AND IMPACTING ROUTE 100B NEAR THE "S" CURVES. IN ADDITION...LAW ENFORCEMENT REPORTS MUZZY ROAD NEAR NORTHFIELD IS CLOSED DUE TO ICE JAM FLOODING. Link to comment Share on other sites More sharing options...
MattdWX Posted March 6, 2011 Share Posted March 6, 2011 7PM Lyndon State College, Vermont 27F light snow 2"+ snow on the ground storm total forecast: 14-19" Link to comment Share on other sites More sharing options...
OKpowdah Posted March 6, 2011 Share Posted March 6, 2011 What's the temp up your way? I wonder if you get a good deal of IP around there. Down to 34.6F now. There's really not all that much of a warm layer, so yeah, I think more in the way of a RN-IP situation is likely with maybe 3 hours of ZR in the middle.

OKpowdah Posted March 7, 2011 Share Posted March 7, 2011 Nice. Probably a steady but perhaps slowing of cooling there. Have fun. I'm hoping for some good icing! Also during the heavier precip, probably some dynamic cooling will help turn us over to more IP 3-4" of sleet would be pretty amazing Link to comment Share on other sites More sharing options...
