yoda Posted January 3, 2018 Interesting note fwiw 6 minutes ago, OceanStWx said: For what it's worth, the 12z Euro is going to be too far east in the initialization of the surface low. WPC and obs suggest just south of the Keys right now. The Euro was over Eleuthera. The GFS seemed too far north up for the Florida coast. Oddly enough, both models end up catching each other and being almost exactly the same position south of New England. Share this post Link to post Share on other sites

MillvilleWx Posted January 3, 2018 Some minor adjustments for the area at H5 on the Euro. It was a small step in the right direction with a bit more backing of the precip shield back into most of the sub-forum, but it's fairly light. QPF totals never max above 0.1" for anyone west of the Bay expect Southern MD. Euro is still very stingy with precip on the Eastern Shore and the evolution at the surface looks a little strange with the eastward jumps quickly once near our latitude. The Key was H5 was slightly more favorable, so take that for what it's worth. Pretty much all guidance has some precip make it past the 95 corridor, albeit mostly light stuff. Thinking areas west of 95 out to Rt 15 could see some flakes flying by early Thursday morning, even if it's light. Eastern shore on a line from Cambridge to OCMD will be the sweet spot for this one. Blizzard conditions will be possible along the immediate coast during height of storm. Friday looking brutal in terms of wind and cold. WC's likely in the single digits to below 0 for everyone. 3 Share this post Link to post Share on other sites

It's probably stingy because of the wacky micro-cane evolution between tau 30 and 42 that vacuums up most of the moisture transport and forcing at the expense of everything else around it. Literally develops an obvious convective-induced mesolow and drops it from 999 to 961mb in 12 hours, which then becomes the dominant SLP with hurricane force winds at the surface right around the center. A strip of 3"+ 6-hourly QPF right along that track and 15-20C 850mb temps in the core. Downright subtropical. Seems to be suffering from the same disease as some of our higher-res friends in previous runs (some of the 3km NAM runs come to mind). 1 Share this post Link to post Share on other sites
Amped Posted January 3, 2018 Euro still a disaster. Has like .05" liquid for most of the area, calling for snow is a risky proposition. This is a windchill maker. Share this post Link to post Share on other sites

Yeah, it's really tricky but fascinating to watch baffle the models. Do you think we'll get any clarity in the guidance in the very short range as we start to see the low to the south develop?

When I looked at the H5 progression, it looked better than last run, and you can see the height pattern change just enough to put west of the Bay back into the game. The weird part for me was looking at the overall surface reflection and I see exactly what you are pointing out. Sitting at work and told my coworker that the surface reflection just looked so wonky and jumpy and low centered within convective clusters each time is a good sign that something is up. Definitely seen this song and dance before with other storms. I'm in full agreement with you on placement of low will be closer to the coastal front. Low will want to stay along the baroclinic zone. That's good for our Eastern shore friends with better alignment of H7 frontogenesis along and just in of the coast. 1 Share this post Link to post Share on other sites

I think you have to at least call for a chance of snow. It might be 50% for west of 95 with 30-40% back to Rt 15, but as a forecaster, you have to cover for the potential. Unless we see unanimous shift to greater than 0.1" west of 95, then an Advisory is probably not necessary and can always add one when something begins to fall. If you call for nothing and it happens, that's when people start lambasting you. The public is a cruel S.O.B when it comes to snow forecasts. Share this post Link to post Share on other sites

Yep, that ORF-DOV corridor looks pretty good right now, maybe a smidgen NW of there if H5/H7 continue to trend a bit more NW with time and the low hugs the coastal front a bit more. 1 Share this post Link to post Share on other sites

Particularly in this case, with the super cold antecedent ground conditions. Any snow that falls will stick and could cause traffic problems. THAT'S when the public starts the lambasting.

Roger Smith Posted January 3, 2018 This is about to explode, current analysis would suggest main low is forming southeast of Miami FL and arctic wave is (can't believe I am typing this) in the northeast Gulf of Mexico, snow is about to break out between TLH and GNV. Upper support is massing over AL-wGA, and it's probably going to run right up the coast to Hatteras, try to hang a left, then lurch east-north-east, but not in time to spoil your potential snowfall event. First call 1-3" DCA-IAD 3-5" BWI 8-15" Delmarva 14-22" se VA 2-5" e PA and most of NJ 4-7" NYC 8-15" w LI to w/c CT to w MA 15-30" e LI, most of s NE, VT-NH 20-40" Maine, NB 10-15" w NS 1 Share this post Link to post Share on other sites

I'd sell my soul and give all that I have just for a one DAY and night of watching this storm in Maine! WOW ALMOST FOUR FEET of snow!!! Storm of a Lifetime!
