TalcottWx Posted October 29, 2011 Share Posted October 29, 2011 24 hr is 0z... the precip ends a few hrs prior to that most likely. Damn Will on the other subforum said it was east and colder.. Link to comment Share on other sites More sharing options...
Ian Posted October 29, 2011 Share Posted October 29, 2011 Warmer where? the 850s would seem to crash quickly if they are that far S and E at 24 at 24 hrs the 850 line is basically identical to 12z if it's not at 18 (which it is pretty darn close but maybe a smidge west) Link to comment Share on other sites More sharing options...
Ian Posted October 29, 2011 Share Posted October 29, 2011 Damn Will on the other subforum said it was east and colder.. it looks a bit colder up there (sne) maybe.. here it's really the same probably when factoring in a margin of error Link to comment Share on other sites More sharing options...
TalcottWx Posted October 29, 2011 Share Posted October 29, 2011 at 24 hrs the 850 line is basically identical to 12z if it's not at 18 (which it is pretty darn close but maybe a smidge west) Oh well, EURO at lunchtime had some flakes to end at least Link to comment Share on other sites More sharing options...
ORH_wxman Posted October 29, 2011 Share Posted October 29, 2011 it looks a bit colder up there (sne) maybe.. here it's really the same probably when factoring in a margin of error Yeah down there it has the 0C 850 line over I-95 pretty much at 18 hours...maybe even a bit west of that.

yoda Posted October 29, 2011 Share Posted October 29, 2011 Yeah down there it has the 0C 850 line over I-95 pretty much at 18 hours...maybe even a bit west of that. Does the EURO even show snow down here at all then? Link to comment Share on other sites More sharing options...
ORH_wxman Posted October 29, 2011 Share Posted October 29, 2011 Does the EURO even show snow down here at all then? It collapses pretty good between 18z and 00z...we'd need to see the wunderground 3 hourly maps to see how much gets down to I-95. It looks like it would end as some snow...esp W of the fall line. Interior N MD elevations near PA border almost certainly gets accumulating snow. Link to comment Share on other sites More sharing options...
Ian Posted October 29, 2011 Share Posted October 29, 2011 Does the EURO even show snow down here at all then? Euro/GFS blend with a sprinkling of NAM. Near 95 probably hope for a rogue superband to end tho we may mix/change earlier for conversational snow. I'd take 30-60 min of mod+ if forced.

psuhoffman Posted October 29, 2011 Share Posted October 29, 2011 Does the EURO even show snow down here at all then? euro has tightened the thermal gradient in this area, its slightly warmer if you are right along 95 or east, but it is actually colder if you are 20 miles west of 95 and points west. 850s at IAD are -.02 at 12z, -2 at 18z and -4.2 at 0z. Precip is .58 from 12z to 18z and .22 after 18z Link to comment Share on other sites More sharing options...

Nikolai Posted October 29, 2011 Share Posted October 29, 2011 There is always a prelude of things to come.. this Winter is going to be awesome for some reason this is giving me images of 95-96, just the transient nature of everything juxtaposed with the strength of the system... but my analogs are still 08-09, 62-63, and 56-57 (in that order). we're in a very cold spell right now, yet we should be rather mild next week, although it appears we may go cold again soon after... wouldn't be surprised if we turn out snowier though, as the QPF of recent events has just been phenomenal...

March thru the past few months have been very wet. If the wet pattern continues this winter - it's likely that we will end up with above normal snows for the season as well as a lot of rain.

ksstormhunter Posted October 29, 2011 Share Posted October 29, 2011 06Z SmartCast, now tracking Hot Springs, VA with potential of 7.6 inches of snowfall in the next 6 hours, visibilities to 1/8 mile, and snowfall rates between 9-12Z up to 1.5" per hour. Also other areas that need to be watched are Shenendoah, KJST/KLWB as those areas can see 3" in the next 6 hours. Link to comment Share on other sites More sharing options...
winterymix Posted October 29, 2011 Share Posted October 29, 2011 Some mysteries solved: LARGE DIFFERENCE BETWEEN 00Z NAM AND GFS IN THE THERMO PROFILE BLOH7 AND MOST IMPORTANTLY BLO H85. KIAD 06Z SOUNDING SHOWS THAT THE GFS IS TOO WARM AND THE NAM IS TOO COLD AS EVIDENCED BY COMPARING THE MODEL SOUNDING PLOTS AT 06Z TO OBSERVED BALLOON. THIS SUPPORTS THE WIDE DISPARITY OF MODEL SNOW ACCUM EAST OF THE BLUE RIDGE...WITH THE NAM GIVING IAD 11 INCHES OF SNOW AND THE GFS GIVING ZERO INCHES OF SNOW. WILL BE USING THE 21Z SREF AS THE BASIS FOR THE SNOW ACCUM AND TIMING. HPC ANALYSIS SPEAKS OF A RECENT NAM UPGRADE THAT MAY BE PRODUCING A COLD BIAS IN THE MODEL.
