"pattern changing" event, which lingered as it tapered off.
Lake Flake Scale: *** 3 FlakesAfter perhaps
our mildest and quietest six week winter period on record, winter roared back
into western and central
, courtesy of a fairly significant lake effect event. Deep low pressure moved up
just to our west early on Sunday 5th, which resulted in rain for our
region, but the backside of the storm swept into the region following a cold
front Sunday afternoon with "upslope" snow developing in the hills
Buffalo by early afternoon. As the cold air deepened and moisture was stripped away,
the activity became more lake enhanced and eventually purely lake effect as the
night wore on. Strong westerly winds carried the activity well east into
counties where several inches accumulated. Over a foot fell by Monday morning
on the Chautauqua ridge, but little if any in the
Buffalo and Rochester areas. A similar scenario evolved east of
Ontario, albeit several hours later. A foot piled up by Monday morning on the northern
portion of the Tug.
most persistent lake effect came on Monday
the 6th as a deep westerly fetch of cold air crossed the unfrozen
waters of Lake Erie and continued to pile up heavy snows from southern Erie and
Wyoming counties southward into the northern portions of Cattaraugus and
Chautauqua counties, with some activity extending into Allegany county. Winds
diminished later in the day and began to veer more northwesterly, and activity
began to affect Wayne and Monroe counties. A single multi-lake band extended
across Huron and into Lake
for a time Monday evening, and this band gradually settled southward as the
winds continued to veer. Several inches fell Monday night and Tuesday morning
as well as Oswego county and the
area. Additional accumulation also resulted over the western southern tier, but
amounts were less than in the previous 24 hours.
saw a general weakening in the activity as the inversion lowered and winds
veered even more northwest, but remnants of the earlier uplake band settled over
Buffalo area and dropped a few
inches during the afternoon and evening.
This activity lingered into Wednesday morning (8th) and
settled south again before becoming scattered by later in the day.
totals for this three day plus event reached two feet over some higher
Wyoming to Chautauqua counties, and over a foot over all the higher elevations from far
Erie county southward. 3 to 6 inches fell further north, including metro Buffalo
and Rochester (the largest snows in almost two months here!). Off Ontario, the Tug received one to two feet, with
lesser amounts farther south across Oswego county as the bands were more migratory.
One unusual facet of this event was the
activity. It is rare for a significant lake event off Erie
in February, but the lake is wide open this year due to the previously mild
winter, so the potential for lake effect remains. This was a notable significant
event, but focused mostly on the typical "snowbelt" areas and had
little affect on the metro areas. It earns ***
3 Stars ***.
