CNY-LES FREAK Posted December 10, 2019 Share Posted December 10, 2019 With the way things are looking, I'll give us about a 30% chance of a white Christmas this year and for this area, that is not a big number unfortunately but that's what we get for way below normal temperature regime and an above normal snowfall regime during the month of November!Sent from my SM-G970U using Tapatalk Link to comment Share on other sites More sharing options...

Thinksnow18 Posted December 10, 2019 Share Posted December 10, 2019 The ARW model south buff showed a little bit ago might be on to something...the latest AFD supports those a of 7" not being out of the question for northern Erie specifically metro Northtowns...blowing and drifting will become an issue and the afternoon commute could be rough. 1 Link to comment Share on other sites More sharing options...

wolfie09 Posted December 10, 2019 Share Posted December 10, 2019 An interesting lake effect event will be unfolding tonight through Wednesday night. Confidence in timing and location is fairly high, but amounts and intensity is not quite as high. Weak lake effect processes are now underway generally as expected downwind of Lake Erie with low-topped convection capped at ~7000` with very dry air above that level. This is resulting in light accumulations toward the Chautauqua Ridge this afternoon. Temperatures at cap level will continue to slowly drop through the night but with little or no increase in available moisture as seen by numerous but lackluster upstream horizontal convective rolls over MI. East of Lake Erie... Early this evening, westerly flow along the Chautauqua Ridge and sufficient lapse rates supportive of lake effect processes will result in a period of lake effect snow through the evening hours. An advisory is in effect for traditional westerly flow regions (portions of Chautauqua and Cattaraugus counties), but snow rates overnight may be somewhat unimpressive due to the initial lack of available moisture and still cooling airmass, followed by backing winds overnight that will begin to disrupt any nocturnal consolidation. Do not expect much more than an inch or two in these areas. The more interesting event will occur near sunrise as the band heads north (during the commute) across the Southtowns, and then into Metro Buffalo during the morning. Some strengthening of the mostly singular band is expected during this time with full lake fetch. The band should reach its northern extent by midday, probably just clipping SE Niagara County and part of Orleans County before heading back to the south as the main upper level trough finally moves in. There remains uncertainty on the strength and duration of the band while it lingers over/north of Metro Buffalo and into the Northtowns. But, once it starts to move, it should quickly head south, with the entire lake band swinging south (and/or being pushed into the shoreline), blowing past the Southtowns, and back into the Southern Tier. The band may be briefly strong during the midday/full fetch time period with aided lift from the upper level trough. The band should then begin to weaken later Wednesday evening after losing adequate fetch while the airmass aloft continues to dry out. The lower confidence in amounts is compounded by the possibility of blowing snow. This should may help keep snow amounts down some, but it will also result in a relatively impactful day in terms of travel. While not a banner event by any means, this event should still be troublesome for some. As such, a fairly strongly worded advisory remains in place. Most areas should end up with a an inch or two as the band moves north, followed by another inch or two as the band moves south. Highest amounts should be over Northern Erie County where the band lingers the longest. It`s possible some areas could exceed 7" if the band lingers before heading south, but the emphasis for this event should be focused more in impact from blowing snow rather than amounts. East of Lake Ontario... A lake banding will probably have a hard time getting established until late tonight ESE of Lake Ontario due to the above noted limited moisture availability. Some consolidation is expected during Wednesday as flow backs, with a better defined lake band forming by afternoon with Lake Erie serving as its upstream connection. Once this is established, a lake band should be roughly over the St Lawrence Valley. But with continued limited moisture and less than ideal fetch, snow rates and corresponding snow amounts should be low, at least until the band starts moving back south toward the more traditional/long fetch east of Lake Ontario in the afternoon. An upstream multi-lake connection should then be established ESE of Lake Ontario by Wednesday evening together with the coldest air aloft. This may result in the best opportunity for snow rates of 1-2"/hr, but only for a relatively short duration Wednesday evening. Increasingly dry air aloft should weaken lake bands overnight. Similar to downwind of Erie, areas east of Lake Ontario will be under an Advisory with blowing snow possibly leading to as much of an impact as snow amounts. In general, expect snow amounts to be fairly tame over this traditionally hard-hit region, with most locations staying under 7". Highest amounts should be over the Tug Hill and toward Oswego County (mainly late Wed-->Wed eve), with less, possibly much less elsewhere Link to comment Share on other sites More sharing options...

SouthBuffaloSteve Posted December 10, 2019 Share Posted December 10, 2019 My point and click just got upped from 3-5 to 3-7. Think NWS does see some additional potential with that band tomorrow. Those winds are going to be a huge factor as that band moves back south. Depending on timing could be a very problematic PM commute.WednesdaySnow showers, mainly before 5pm. The snow could be heavy at times. Patchy blowing snow after 9am. High near 30. Windy, with a west wind 11 to 16 mph increasing to 23 to 28 mph in the afternoon. Winds could gust as high as 41 mph. Chance of precipitation is 100%. New snow accumulation of 3 to 7 inches possible.. Link to comment Share on other sites More sharing options...

wolfie09 Posted December 10, 2019 Share Posted December 10, 2019 The northern stream portion of this phasing system mentioned above will likely cross the eastern Great Lakes Saturday night into Sunday. Colder air deepening across the eastern Great Lakes and H850T falling to -11C/-13C will bring the potential for lake effect- enhanced snows east of the lakes. Otherwise, lows Saturday night will fall back into the low 30s by daybreak Sunday morning. Temperatures on Sunday will likely not change all that much with highs in the mid 30s for most locations. The system will move out into the Canadian Maritimes Sunday night and Monday. Colder air continuing to filter into the Great Lakes in its wake will continue to support lake effect snows east and southeast of the lakes Link to comment Share on other sites More sharing options...

Do news stations really have that much capital to make their own weather model with collective balloons and data analysis? I'm pretty sure it's just derived from a mixture of the high res models.

I always wondered how they generate their in house models as well. Something like weather models are extremely demanding and actually really need to be done using quantum computers, NOAA just got a upgrade last year to their super computer which is cool to see. What I think probably happens is they have some sort of program that allows them to import some generated model. After it's imported they can then adjust certain things like wind direction and thats what you see them using. They can do this on their computers since they are't trying to predict the weather, they are basically telling it what they want. 1 Link to comment Share on other sites More sharing options...

I don’t think they tweak the hour by hour runs at all as you’ll hear the say pretty often that they think the model is off because of this or that... If they could add their own input they would. Not sure about the specifics but I know back in the day 4 use to mention using the RPM as the data set for their graphics. Now they just refer to it as their in house model. It would make sense as the RPM runs off the ARW which had similar output on the 12z run. The map Todd used was not the hi res output they showed earlier in the day so in my opinion his map could be more user input adjusted vs just straight computer output. . 1 Link to comment Share on other sites More sharing options...
