ORH_wxman Posted January 18, 2011 Share Posted January 18, 2011 Didn't see an obs thread, but if there was one already made and I somehow missed it, then post the link and I'll merge them. Try to keep this as obs for tracking the sleet line this morning and eventually tracking the rain/freezing rain line. Looks like the light snow has reached HFD before 07z.

Confuzzled Posted January 18, 2011 Share Posted January 18, 2011 Light dusting here in Waterbury CT @ 16 degrees with light but steady snow. Temps dropped all across CT the last few hours which indicates more ice and less rain tomorrow IMHO: 08z temps in CT (last three are on the shoreline) KBDL 16 KDXR 18 KHFD 18 KIJD 18 KMMK 18 KOXC 16 KSNC 19 KGON 24 KHVN 22 KBDR 23 Link to comment Share on other sites More sharing options...

ORH_wxman Posted January 18, 2011 Author Share Posted January 18, 2011 sleet already! Wow the warm air is flying in aloft! I'm surprised its snuck in there...places like HPN and the posters nearby havent mixed with any sleet yet....though its possible that if the precip lightened up a tad it could mix.

Sn0waddict Posted January 18, 2011 Share Posted January 18, 2011 Haven't been able to go outside, but I haven't heard any sleet ping on any windows are anything like that. Link to comment Share on other sites More sharing options...

Also I should add that I mentioned in the NYC thread that the sleet on the northern fringe there was being caused by a very strong warm punch from the SE at 900-950mb....not the usual 800-850mb being the warmest layer as we so often see in sleet. The 925mb warm punch will encounter a lot more resistance inland where the thermal gradient is stronger, so we'll have to watch that...sleet line could come to a halt for a bit.

FitzWx Posted January 18, 2011 Share Posted January 18, 2011 Holding at 12 in Amesbury. If winds hold from NE would think temps may not rise above freezing with cold air draining from North. Just a thought. Link to comment Share on other sites More sharing options...
rgwp96 Posted January 18, 2011 Share Posted January 18, 2011 hearing some sleet now. im right at the 41.0 lat Link to comment Share on other sites More sharing options...
moneypitmike Posted January 18, 2011 Share Posted January 18, 2011 Yup, snowing here in Shelburne. BSpots that had been cleared are covered. By my temp, it looks like it might have begun right after 3:00p.m. as I had a high temp of 13.3 then, now down to 11.8. Link to comment Share on other sites More sharing options...
MaineJayhawk Posted January 18, 2011 Share Posted January 18, 2011 Temp here has risen 10° in the past six hours .... from -7.0F to the current 3.7F Mentioned in the other thread that GYX is leaning toward cold. Link to comment Share on other sites More sharing options...

ORH_wxman Posted January 18, 2011 Author Share Posted January 18, 2011 It seems the NAM is doing better than the GFS and ECMWF for the thermal profiles aloft on the 00z guidance...the sleet has penetrated the lower Hudson Valley and SW CT....something that the other guidance said wouldn't happen until about 12z. Though the NAM may still be too aggressive with the advancement of the sleet line by 12z where it had it up at the MA/CT border NE of Kevin at 12z....the 06z NAM backed off on that idea running it just S of HFD or so.

nzucker Posted January 18, 2011 Share Posted January 18, 2011 And we have ZR mixed in with the sleet now I can confirm that in Westchester....definitely a mix of ZR and sleet, nasty night and may be getting very slick soon. 25.7F Link to comment Share on other sites More sharing options...

Confuzzled Posted January 18, 2011 Share Posted January 18, 2011 Here comes the yellow... I don't think its sleeting but the snowflakes seem harder now....I can also hear them fall....I think there is some partial melting and refreeezing on the way down. So nice and quiet outside in the snow! Link to comment Share on other sites More sharing options...
