Temps today at Bittinger 2nw Valley, Cabin Mt, national profile this afternoon

 

 

Temps at The Glades dropped below 0 again this morning, with some cool looking hoarfrost around. Many get hoarfrost and rime mixed up. This is hoarfrost, rime is what we get across the high ground often with fog events in winter

 

 

Thoughts ahead on snow this week. The storm tomorrow is mainly a southern Alleghenies event as it looks now. With lighter amounts north. More impressed with the upslope there after through Friday a.m than tomorrow’s event. Unfortunately for snow lovers, this did not become the “Big One”. Lots of ingredients on the table but didn’t time out right.

A generalization map in part 1 for tomorrow.  Leaning low in those amounts.

Part 1 is tomorrow’s event, Part 2 is upslope Tuesday through Friday a.m

Snowshoe 9pm.

Big questions remain Sunday-Monday. How far north will the low track? We need the current system to lift away asap. That may try keep it south. Right now central/southern Alleghenies stand a better chance than the northern. This can change. Gut says should. Behind this it does look like we set up more upslope regardless of exact track.

         ON THE MODELS

“7 a.m update- Looking like a 2-5″ snow Wednesday a.m tbrough Thursday p.m for Garrett, Preston, Somerset, Fayette. 3-6″ across the high Wv ground in favored upslope areas. Thursday p.m through Friday p.m 4-6″ region wide with pops to 8″. Wednesday to Saturday totals 5-11″ north, 7-12″ Wv with pops in both areas over that amounts.

0z ECMWF loses weekend system. Likely typical error of the model struggling with the Rockies..0z and 6z GFS shifted back north from yesterdays 12z and 18z runs. System needs watched. ”

7pm update-  Watching a possible snow burst in the 5-9 am window that may affect morning in areas. Overall, status quo from the morning update. If any changes were made in regard to the snow Wednesday a.m through Friday p.m it would be to slightly up overall totals.  Thursday night into Friday lookd like really good upslope.

The weekend system.(Sun/Mon)  I dont expect models to get a handle on it until Friday. We have seen the possibilities. The Euro is struggling from systemic errors from this time period. The GFS had a formidable event. We need to clear the field of this first main event and inch closer to that time period. Overal the setup remains there for a storm. Many who follow the ECMWF will write this off.  Bigger pattern picture has this in play. I’ll spare all the graphics tonight.

8;40pm update- line of storms developing much better than modeled from Charleston to west of Morgantown. The HRRR is picking up on this somewhat. Needs watched as of this line or individual cells hold together, pockets of brief but very heavy snow can occur in the 10pm to 2am time window. Brief whiteouts, and poor travel would develop rapidly. Hrrr showing pockets of 1-2″ per snow amounts in which these pockets would not last but 30-45 minutes max. The line is better developed than modeled at 8:40pm.

       ON THE MODELS

18z 3km NAM modeled temps from current through Thursday a.m. This model excels with tomorrow’s setup. Temps holding at or below freezing in north central Garrett and points north and east as well as areas of the southern Alleghenies. The just ever so slightl above freezing air pushes into Tucker. This is accompanied by very light precip that may put down a trace of ice in spots tomorrow.  Therefter into Wednesday, we start to talk snow.

GIF-180305_184523

 

 

18z GFS .. Snow opportunity Wednesday, Thursday, Friday, and Gfs operational at 12z and 18z trended south with Sunday event. Operational models will waffle each and every run. 18z was further northwest. GFS ensembles actually look better tonight for the event vs last night. Wednesday a.m through Friday snow totals look to run in the 5-10″ range with pops to 12″ in favorable areas.  Those being the favored upslope spots, and especially northern Alleghenies. I’d expect possible school delays mid to late week. GIF-180305_192636

Amounts off the 18z GFS. Thats Wednesday morning, then Thursday morning, Friday morning, Saturday morning(these are running totals) then hopping to next Tuesday with the 18z GFS op with big system affecting southern Alleghenies. I do think that will trend NW.

 

 

12z ECMWF… Similiar to GFS. (Wednesday areas below 2500-2800′ may struggle to accumulate in afternoon). Amounts overall look similiar through Saturday a.mGIF-180305_195119

Snowfall off 12z ECMWF, Wednesday morning, Thursday morning, Friday morning, Saturday morning and a jump to Tuesday. ECMWF quicker moving, and weaker with the big event at 12z after a monster at 0z.

 

The big system. Despite what the operational models did today, I still really like the setup. I think it does occur and we will be talking 100-150 miles this way or that way to say who gets it. The pattern to me argues a further NW trend vs what operational models did today.

 

Deep trough off west coast, amping the western Ridge, should allow phasing and a pullback further west than todays runs. I like the Tenn/Alabama border to Delmarva track currently. With widespread snow shield north.

12z ECMWF ensemble/control low locations…lots of members Sunday night on the north side yet. Overall mean has trended SE a tad on the ensembles, the control had the most significant difference. Will look for trends tonight on the new run.

 

Watching the steering wheel. How this digs, and progresses will direct the low more NE or ENE. Subtle differences from 0z to 12z ECMWF op run.

That PNA popping positive, is a good thing to turn it north. Will it be enough, time will tell. Does the trough deepen and go negative? Questions remain, but this is our best shot of the season. Screenshot_20180305-191101.jpg

18z GFS ensembles, control/comparison to yesterday. First pic 18z gfs control yesterday for Sat night/Sun a.m. 2nd pic today. 3rd pic Sun night/Mon am, 4th pic today. 5th and 6th pic ensemble members for low position eith overall mean Sun-Mon and that last pic is 18z from yesterday. Euro trended SE weaker. GFS trended NW within its means.

 

Bottom line: Models are still getting a handle on a player thats not on the field yet. We need to get past these first systems mid to late week. The overall pattern is setup to support this storm. The question will come down as always to timing, phase, track. This is our best potential of the winter of a major storm.

Temps today at Bittinger 2nw Valley(only through 1pm, will update those asap) and Cabin Mt 4350(some high spots remaining below freezing today) aa well as national profile this afternoon and a closer view in. When you look at the satellite image of snowcover and then at the temps, easy to see the role it plays, especially across N.Y. Our area is combo of elevation, and snowcover in some areas.

12Z GFS Surface next 10 days. Best shot of something significant for the Alleghenies looks to be between the 11th and 13th(next Sun-Tues). That doesn’t mean nothing between now and then. Some upslope snows mid to late week. Slightly higher amounts to what we just seen 2 days ago, with a more prolonged period, with less in the way of extreme wind. More of what you would classify as typical for the area. GIF-180304_161052

12ZGFS modeled amounts on late Wednesday/Thursday/Friday/Saturday and then jumped till Wednesday a.m. This is only a model run, not a forecast. I am a tad high on thinking this occurs. Are their bugs in the ointment, rivers to cross, hills to climb?Yes! One being we first have to get through the midweek event and see where things stand. Then models can get a better handle on the one I think can be our main potential pf significance.  I love the fact the models teleconnections(pictured 12zgfs, ecmwf below) spike the PNA positive at the time frame. NAO is already negative and not badly positioned for us. Spike in PNA idicates to me, its not flying out to sea.

12ZECMWF at the surface. GIF-180304_165452

12ZECMWF modeled snowfall. End of Wednesday/Thursday/Friday/Saturday and then a jump to Tuesday a.m. The ECMWF is a tad faster in with that system. Again, I stress these are model runs. Not forecast. I do like this timeframe though.

At 500mb on Ecmwf – op/ensemble for the 11-13th window

Big trough off west coast, reflection should be big trough on east coast. +PNA, west based -NAO which is favorable for us(if you like storms) that combo should keep this west and not out to sea if the models verify somewhat. As of today, and with weather, things change often, but as of today, I’m anxious to see how this timeframe plays out. Lots of potential. The 11-13th. AND we have winter weather before that as well.

Snowfall amounts. Bittinger 2nw Valley : 2.8″, 92.6″ on the season.  This was a difficult snow to measure.  As mentioned before, this site is protected and minimally affected by wind. This event, no areas immune to wind. I did a on the board measurement. Which I am pretty sure may had some blow off but not on. Did several nearby on the ground checks, similar average. High ground literally had nothing on the ground to small drifts. There was no air left in the snow for sure.

Canaan Heights. 6.8″ total with the event. 107.8″ on the season

Wind gust ramped up to 65mph last night on northern Cabin before the anemometer froze up. Same for some other sites. Very well within reason that 70-80mph gust occured.
