dryslot Posted November 23, 2011 Share Posted November 23, 2011 What's the lag time between leading edge of the radar echoes and precip for this one? Looks like its a mix on radar at Jaffrey but don't know if thats just virga or not Link to comment Share on other sites More sharing options...
HoarfrostHubb Posted November 23, 2011 Share Posted November 23, 2011 What do we think for Rindge, folks? 1-3" is my guess with the precipitation mostly being sleet/rain. Being this far southwest in the state is going to make a huge difference in this one, unfortunately. 18z NAM looked a little colder than the GFS but still not chilly enough to get excited about right on the Massachusetts border. 2-4" Monadnock Magic Link to comment Share on other sites More sharing options...

ORH_wxman Posted November 23, 2011 Share Posted November 23, 2011 Seeing a few ip mixing in here in southern ct? 43/41 explanations? The boundary layer just above the surface is probably quite dry so you are getting evap cooling in that part of the column which turns the rain into sleet pellets. This type of sleet usually lasts less than 20 minutes...once the BL gets saturated, it goes to plain rain. Link to comment Share on other sites More sharing options...
dendrite Posted November 23, 2011 Share Posted November 23, 2011 Seeing a few ip mixing in here in southern ct? 43/41 explanations? Probably a dry layer aloft that is wetbulbing down below freezing enabling IP to form and reach the ground. Link to comment Share on other sites More sharing options...

dendrite Posted November 23, 2011 Share Posted November 23, 2011 SREFs are a tad warmer tomorrow morning at 700-850...looks like the 850 0C tomorrow morning at 12z runs from about LEB to LCI on the mean. It seems that once the models finally honed in on the strength of that high/CAD the typical SWFE model bias of the warming H85-75 trend commenced. I'm hoping to pull off 3-6" before the pellets start flying. Link to comment Share on other sites More sharing options...

Ginx snewx Posted November 23, 2011 Share Posted November 23, 2011 Critical thicknesses seem to be a tad north than progged, going to be very close for Brian but UVVs may save him from a complete pelting. Link to comment Share on other sites More sharing options...
MarkO Posted November 23, 2011 Share Posted November 23, 2011 My place in Campton is 5 miles north of Plymouth at exactly 1100'. Should get a nice dump. Where in Campton? I just built a house on Campton/Thornton line in Waterville Estates at same elevation. I'm usually up there building on weekends and this storm is killing me.
