Thunder Road Posted February 2, 2011 Share Posted February 2, 2011 28.7°/28 at this rate we'll be above freezing by 4am. I assume when the northeast winds kick in we'll drop again a bit? Wind is solidly from the ENE now... Link to comment Share on other sites More sharing options...
Isotherm Posted February 2, 2011 Share Posted February 2, 2011 Keep in mind the intial quick temp rise is expected as pcpn intensity increases from light-mod-heavy due to latent heat release at the surface. After this, NELY winds should cause temps to flat-line just below 32, probably holding 30-32 for most overnight. Link to comment Share on other sites More sharing options...
isnice Posted February 2, 2011 Share Posted February 2, 2011 Temp has climbed to 25F since the moderate freezing rain started. That's a pretty quick rise for you as well. I didn't expect you to be at 25 this early on. Link to comment Share on other sites More sharing options...

Nice post Tom....after a 1-2 degree rise...we have held steady here at 28.1....looks like glass out there.... Link to comment Share on other sites More sharing options...
Absolute Humidity Posted February 2, 2011 Share Posted February 2, 2011 Temps seem to fluctuate between 28 and 29 currently 28.4. Currently light zr and sleet. Pretty cool to see sleet, didn't think sleet would mix in here. Commute to Somerset Co will be bad I'm sure, have to go in early as well to implement disaster recovery shd we loose power as I most certainly expect it. Lost power last week durning the thunder sleet. Link to comment Share on other sites More sharing options...

Thanks Tim, it's rapidly becoming dangerous out there. 29F and mod-hvy ZR here in SE PA. Link to comment Share on other sites More sharing options...
NJHurricane Posted February 2, 2011 Share Posted February 2, 2011 Light freezing rain here in Woodbury NJ...31f, up 1 degree with the arrival of rain that is heavier than drizzle. With marginal below freezing temp, so far ice accrual is not even across all surfaces...probably already .10" on cars/metal surfaces, railings, vegetation and snow pack. None so far on my road or sidewalk. Agree that thus far latent heat release is cause of bump in temp as wind here is out of the NE and has been NNE to NE past 3 hours.

blizzardlover Posted February 2, 2011 Share Posted February 2, 2011 Very heavy echoes coming out of NE MD, heading into New Castle CO, Chesco, LanCo. Sleet? Link to comment Share on other sites More sharing options...
johnc Posted February 2, 2011 Share Posted February 2, 2011 Chillin' at 30.2 with some light-to-moderate rain and winds shifted from the east, up from 28.4 before the rain began. I think it might be raining heavy enough to minimize some of the icing potential... maybe. Lie to me and tell me it's going to be okay. Link to comment Share on other sites More sharing options...
BucksCO_PA Posted February 2, 2011 Share Posted February 2, 2011 temp up to 28.7 now as the mod rain moves quite a band approaching ILG my untreated neighborhood streets are a complete sheet of ice Link to comment Share on other sites More sharing options...
LocoAko Posted February 2, 2011 Share Posted February 2, 2011 For the time being we seem to be become stationary at 28F here. Heavier echos making their way in from the W and SW. Link to comment Share on other sites More sharing options...

LVblizzard Posted February 2, 2011 Share Posted February 2, 2011 That's a pretty quick rise for you as well. I didn't expect you to be at 25 this early on. I'm guessing it'll stall around 25-26 until about 6-7am when temps start to gradually rise a degree or two per hour. Link to comment Share on other sites More sharing options...
goldstar Posted February 2, 2011 Share Posted February 2, 2011 Wonder how long the sleefest holds on, and who ends up getting the heavier icing. Link to comment Share on other sites More sharing options...

Quincy Posted February 2, 2011 Share Posted February 2, 2011 28.7 now with mod ZR. some 50dbz readings in SE PA. I can't imagine that's sleet, so some people may be hearing rumbles of thunder before long... Link to comment Share on other sites More sharing options...
RU848789 Posted February 2, 2011 Share Posted February 2, 2011 Skating rink! Freezing rain accruing quickly here in Metuchen. Just walked around and my street is completely ice-encased - took a full run and slid about 15 yards. My driveway has a bit of an incline and was very hard to climb up. I, too, love all kinds of wintry weather, even ice, so sue me. Temps up to 27F from 26F an hour or so ago. Not sure if this is temporary related to the latent heat of fusion heat release to the atmosphere from the phase change from liquid to solid; I know it's about 1/7 the energy per mole of water as compared to the heat of condensation (or vaporization, which leads to evaporational cooling of the column as it saturates), so it would have a lot less temperature impact than evaporative cooling, but it's not zero, either. Would need to do a proper energy balance, but it's been a few years, lol... Link to comment Share on other sites More sharing options...

CoolHandMike Posted February 2, 2011 Share Posted February 2, 2011 Anyone in that band west of PHL? Looks like hvy ZR in Lancaster. I'm in West Chester which is just about to get hit by that. I'll go out and check in a few minutes. It's been steady freezing rain here for about an hour now though--last I checked, my apartment parking lot was covered in ice with about 1/8" accretion on the iron railing on the sidewalk.

greg ralls Posted February 2, 2011 Share Posted February 2, 2011 That heavy band in Chester County looks to be only around 20 minutes away from me. Light ZR right now, but that is about to change. I was just peeking out the one window towards the SW like I do when I'm looking for lightning from an approaching thunderstorm, but saw none.
