Lake Effect Summary - November 28-29, 2008
Maximum Snowfall: Lake Erie 6"
(S. Dayton); Lake Ontario 12" (Redfield)
Duration: 24 hours +/-
Prime Feature: Marginal
frontal enhanced event.
After just a 6 to 12 hour break, another lake effect event got underway early on Friday 28th in the wake of another weak frontal
passage. 850 mb temps which had risen to -5°C or so late Thursday fell off to -7°C to -9°C again by Friday morning, just
cold enough to set off the lake machine again.
Snow developed immediately following the frontal passage along the Chautauqua ridge and up into southern Erie and Wyoming counties
near daybreak Friday and continued until about midday before winds veered and shear increased, pushing bands southward and weakening
them into a few multiple bands by evening. Much of the region had 3 to 6 inches, with most of falling between daybreak and early
afternoon. The Erie activity shut down during Friday evening.
Off Lake Ontario, the activity focused on the Tug Hill, developing during the morning Friday and continuing through the evening
before gradually shifting southward as winds veered early Saturday morning. The activity ended by midday Saturday as cap lowered and
ridging built in. Heaviest snows fell across interior northern Oswego county and southern Lewis county where a foot or so fell.
Lesser amounts fell nearer the lakeshore and temperatures were marginal.
This was the fifth event so far in November, tying 1995 as the most ever in November in our 15 years of record. Many lake effect
locations have seen near record November snowfalls this year.
The event was marginal, brief, and affect few people. It therefore earns one * star.
Here are some representative reports.
