Upstate/Eastern New York-Pattern Change Vs Tughill Curse?


Recommended Posts

Southwest flow continuing tonight ahead of an approaching arctic
boundary. This will continue to keep the potential for accumulating
lake snows east of Lake Ontario. Depth of synoptic moisture
increases and improves the potential for accumulations which will
last into Sunday, as the arctic boundary drops through. Several
inches of snow is certainly possible especially on the Tug Hill.

Conditions to look favorable for the development snow squalls on
Sunday, especially during the afternoon as the arctic front presses
through. A 45-50 knot low level jet will be passing overhead,
bringing the potential for gusty winds. Any snow squalls will move
southeast along and behind the front, with briefly intense snowfall
rates around 1"/hr and gusts up to 45 mph. Any wet roadways will
freeze quickly as temperatures plummet behind the boundary.

 

Strong cold air advection continues behind a cold front Sunday
night. Lake effect snow showers will develop south of the Lakes as
flow veers from west-northwest to northwest. Conditions improve for
lake effect snow south of Lake Ontario as 850mb temperatures fall to
-18C and inversion heights become 5-6k feet. The RGEM suggests the
Genesee Valley to the Finger Lakes as the most favorable spot for
minor accumulations into Monday morning. Cold Sunday night with
temperatures in the single digits across western NY to the minus
single digits east of Lake Ontario.

Notice no mention of Lake Erie??? All need a new profession.

If you loop this radar you can see the LES off Huron. The stronger sun this time of year is preventing a stronger band from forming and keeping it cellular. KBUF mentions this in their AFD.

although a strengthening sun should help to make the activity more
cellular and thus less impactful.

WINTER WEATHER ADVISORY IN EFFECT FROM 10 AM TO 7 PM EST
SUNDAY...

* WHAT...Lake effect snow expected. Total snow accumulations of
  3 to 6 inches in the most persistent lake snows. Winds gusting
  as high as 40 mph.

* WHERE...Oswego county.

* WHEN...From 10 AM to 7 PM EST Sunday.

* IMPACTS...Plan on slippery road conditions. Areas of blowing
  snow could significantly reduce visibility.

Another NW flow "event" tomorrow? Vort and Blizz in Skan are having a good winter with all the NW flow. Geesh. I often get in on the edges of NW flow bands but the best snows are definitely over Cayuga, S. Onondaga, and Cortland counties. 

Anyways, getting a nice snow shower, I think off Lake Erie, for the past 10 minutes.

Lake Erie looks to be getting its act together again.

Should get even better organized as we lose the suns heating effects. Not sure it gets as strong as this mornings but we’ll see. I love when we get these events that no one forecasts and it’s just a complete guess to wether we see flurries or 3”/hr rates.
