tamarack Posted September 30, 2014 Share Posted September 30, 2014 For Wednesday. Just read the Grey Maine afternoon discussion, they don't seem very enthused about meaningful rainfall. Not until Saturday, and it sounds like the heaviest then would be hit or miss. Link to comment Share on other sites More sharing options...

powderfreak Posted October 1, 2014 Share Posted October 1, 2014 If we get some breezy conditions and heavier rain on Sat/SatPM, going to be heavy heavy leaf drop. From BTV... "Latest 12z GFS and 00z ensemble data in excellent agreement with closed 500 mb/7h cyclonic circulation lifting across the central Great Lakes on Saturday and into central Canada on Sunday. Meanwhile...potent 500 mb vorticity will round developing trough axis and create a negatively tilted middle/upper level trough across our region...which will help advect deep Atlantic moisture into our forecast area. Have noted GFS ensemble precipitable water values between 1.50 and 1.75" on Saturday afternoon...which is 1 to 3 Standard above normal. This combined with favorable 500 mb positive vorticity advection from vorticity and strong ribbon of uvv's will result in a 6 to 10 hour window of rain across our County Warning Area on Saturday. Thinking arrival time will be around 12z slv...and 18z dacks/western cpv...and into eastern Vermont by 00z Sunday. Given the available moisture/dynamics and slow progression of surface boundary...thinking quantitative precipitation forecast will range between 0.25 and 0.75" with localized amounts near 1.0 likely." "Also...watching the potential for breezy/gusty south to southeast winds on Sat afternoon. Latest 12z GFS continues to show 925mb winds of 45 to 55 knots...along with 850 mb jet of 60 to 65 knts. However...these strong winds are closely associated with the heaviest rain axis...which may limit mixing to the surface. Thinking gusts between 35 and 40 miles per hour will be possible the slv/dacks/western slopes...and parts of the cpv on Sat. This will need to be watched closely as event becomes better sampled by our local hi resolution models. " Link to comment Share on other sites More sharing options...

eekuasepinniW Posted October 3, 2014 Share Posted October 3, 2014 Those abbreviations are painful to read. Thankfully we're moving away from those. How would that have worked? Did the guy type it out normally and then it gets abbreviated by some automated system? I could type all that in a few minutes, but I think my brain would explode if I had to stop and think about abbreviating every possible word.

ono Posted October 4, 2014 Share Posted October 4, 2014 That is true. I will never forget the one last November. That was essentially a highlight of the entire winter.

dendrite Posted October 4, 2014 Share Posted October 4, 2014 0.04" of drizzle so far going back to late last night. The droplet size is so small that they instantly evaporate when hitting my heated precip detection sensor...i.e. I'm not even detecting any precip. I probably need a second leaf wetness sensor that is minimally heated (enough to prevent dew, but not so much to evaporate drizzle). Link to comment Share on other sites More sharing options...

dendrite Posted October 4, 2014 Share Posted October 4, 2014 That's later than I would've guessed for an average date. Oct measurable is very rare around here. Like Nittany said, about 2/3 into Nov sounds about right. If you look at my sig, I had 3 years without any November measurable. A trace is a lot earlier though. When you're accumulating the snow in NW flow during Oct/Nov, we're usually only getting occasional flurries/graupel showers with temps of 35-45F.

wxeyeNH Posted October 4, 2014 Share Posted October 4, 2014 That's later than I would've guessed for an average date. Probably elevation makes a big difference. Usually its a changeover right at the end of a fropa or snow showers. Many times I am dusted while 600 feet below me misses it. Link to comment Share on other sites More sharing options...
tamarack Posted October 4, 2014 Share Posted October 4, 2014 In 16 years here, these are avg (and extreme) 1sts: Trace: 10/28 Extremes: 10/4 and 11/21 0.1"+: 11/9 Extremes: 10/23 and 12/7 1.0"+: 11/20 Extremes: 10/25 and 12/8 In 2003 our first measurable came on 12/6, the start of a 24" blizzard.

wxeyeNH Posted October 4, 2014 Share Posted October 4, 2014 Thanks for all the info guys. Looks like a nice slug of rain coming up this PM for Vermont and Western NH. Will be my first good rain in a long time. Looks like east areas will get less from this batch coming up from W Mass and Conn. Will sure get dark early tonight.
