SouthBuffaloSteve Posted November 11, 2021 Share Posted November 11, 2021 Going to be close for some areas away from the lake and higher up. Either way should be fun tracking what will likely be our first single dominant band setup of the season. 24 hour RGEM loop shows a nice dancing band Saturday into Sunday here. Next few days could be interesting. I'll be interested in checking the verification of the mesos on band placement and precip output to see whose hot and whose not for the season.

SouthBuffaloSteve Posted November 11, 2021 Share Posted November 11, 2021 BUF updated AFD: Friday night and Saturday the vertically stacked low will gradually push eastward with its axis reaching western Quebec and western New England by early Saturday evening. Its approach will bring in cooler air aloft, enough so to produce lake effect precipitation. Consensus 850mb temperatures drop to -5c across Lake Erie by 12Z Saturday. SSW flow will direct most of the lake effect rain showers across Canada and far eastern portions of Niagara and Erie counties Friday night. A few rain or snow showers are possible across the rest of Western New York, but any of these would be on the light side. Fairly good model agreement that the stacked low and a strong embedded shortwave will move across the area on Saturday. This will provide moisture which will enhance lake effect precipitation, and will also produce rain or snow showers further inland from the lakes due to the shortwave. Flow will shift to the southwest which will direct what should be a well developed band across the Buffalo metro area on Saturday. Still a bit too warm aloft to support lake effect snow, although wet snow or graupel could mix in times. Also added a mention of thunder with this band. A less developed band will develop off Lake Ontario and move across the St Lawrence and then Jefferson County. Further inland it won`t have to be quite as cold aloft to support snow, with rain or snow showers possible with the shortwave. Any accumulation would be minimal with high temperatures in the lower to mid 40s. Models suggest winds will shift to the WSW Saturday night in the wake of the shortwave. Precipitation will once again become mostly lake effect, with bands likely to be centered across southern Erie county and across the Tug Hill. Slightly cooler 850mb temps around -6c could support some snow accumulation, especially across higher terrain. Fairly high confidence there will be lake effect bands, but low confidence in precipitation type due to the marginal temperatures. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... Bands of lake effect precipitation will start this period, with a predominately southwest flow across the Eastern Great Lakes. This will highlight precipitation along the Lake Erie shoreline, and inland across the northern Niagara Frontier, as well as towards the northern Tug Hill Sunday. Thermal profiles are marginal for snow, with 850 hPa temperatures around -5 to -7C at periods start. A shortwave from the northern Rockies will sharpen the east coast mid level trough Sunday night and into Monday. Backing surface winds will send lake precipitation northward...possibly entirely into Canada by Monday morning, while all along more widespread synoptic precipitation spreads over the region with the approaching shortwave. Again thermal profiles are marginal for snow on Monday...and not until the shortwave passes and flow becomes more northwesterly later Monday and into Tuesday that temperatures aloft will cool sufficiently for snow to be the predominate precipitation type. By this time, the lake effect event will be winding down. Link to comment Share on other sites More sharing options...

The cooler air has undercut sooooooo many times this year. I can't believe how many times the Mid-Atlantic and even Southeast has been cooler than Upstate NY (especially stupid Sizzlecuse). 1 Link to comment Share on other sites More sharing options...

Yea now all we need is 850 temps to come in a couple degrees cooler than forecast and it will be deja vu. Link to comment Share on other sites More sharing options...

TugHillMatt Posted November 11, 2021 Share Posted November 11, 2021 This is our new norm because the Pacific Jet is always raging these days...polar Vortex loves to pop up just as we enter winter...the northern Atlantic is torching...the southeast ridge works alongside that... All of these just seem to be stuck in repeat mode. But the Pacific...and that Pacific Jet...common issues this century. 2 Link to comment Share on other sites More sharing options...

Last year the base state was in the IO, which isn't good. This year it looks to be in maritime continent which isn't good but it may be able allow better chance to get into money phases. Convection has stalled in maritme region as of late which has been the reason for pac jet being slop. Hoping it keeps pushing into 7-8-1 as we move past tgiving . When the MJO isn't in your favor you then look at the strat to see if you can get help from that. Luckily we have a strong wave 2 showing up just prior to tgiving week which I feel will deliver a good cold shot around Tgiving timeframe as I have been posting. 3 Link to comment Share on other sites More sharing options...
