Area Forecast Discussion National Weather Service Buffalo NY 412 PM EST Wed Mar 3 2021

SYNOPSIS. A cold front over the Upper Great Lakes will press through our region this evening. This will generate some snow showers while setting the stage for colder weather that will persist through much of the weekend. Notably milder conditions are then slated for next week when the mercury over the western counties will soar into the 50s and possibly into the 60s for the middle of the week.

NEAR TERM /THROUGH THURSDAY NIGHT/. Cold front right on our door step and will push into and through the Lower Lakes this evening.

The cold frontal boundary exits the region tonight, may be just enough snow shower activity to coat the ground in many locations. Turning colder in its wake with our temps back to below normal levels.

Upslope flow in the wake of the cold front to keep some nuisance light snow/snow showers over much of western New York for at least the morning hours on Thursday. Slow clearing form the north during the afternoon Meanwhile. plenty of sun for the North Country. Temps a solid 10 deg f lower Saturday with highs remaining solidly below freezing.

Cold and generally uneventful Thursday night . with only some light lake induced snow showers over parts of the Finger Lakes. Mins in the teens in the west . single digits North Country.

SHORT TERM /FRIDAY THROUGH SUNDAY/. Aloft, an upper level trough will remain anchored over the area through the end of the work week and weekend. This will instill cold air aloft at 850mb to drop into the mid negative teens Celsius, which will be cold enough to support lake effect snow showers south and southeast of both Lakes Erie and Ontario, but mainly south of Lake Ontario. All this said, additional moisture from a few shortwave passages Friday night and Saturday will support the more widespread lake effect snow showers. Overall, day to day accumulations of up to an inch are possible throughout the entirety of the period.

Aside from the lake effect, the aforementioned cold air aloft will provide for below normal temperatures for the end of the week and weekend.

LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/. The trough aloft will push off into the Atlantic as ridging build east. At the surface, high pressure over the western Great Lakes will weaken as it pushes southeast across the region and eventually into the Mid-Atlantic. This being said, expect a period of dry weather starting Sunday night and lasting through Tuesday. The next system looks to arrive into the area Wednesday, thus the next chances for precipitation.

Under the influence of the high, warm air will be advected into the region causing temperatures to gradually warm to near normal for the start of the week before warming to above normal by mid-week. Highs Monday will climb up into the 40s Monday and 50s Tuesday and Wednesday.

With a vast majority of the region still under some sort of snowpack, the warm temperatures will warrant melt, which may cause some flooding. This will be monitored as the warm up approaches.

AVIATION /21Z WEDNESDAY THROUGH MONDAY/. VFR at all terminals ahead of a cold front approaching from the NW. The cold front as it crosses will support mainly MVFR cigs along with scattered snow showers. Vsbys could briefly lower to between 2 and 5SM in these snow showers.

MVFR cigs to improve to VFR from the north on Thursday. MVFR cigs likely to persist for much of the day across the Southern Tier.

Outlook .

Friday and Saturday . Mainly VFR. A chance of snow showers. Sunday and Monday . Mainly VFR.

MARINE. Winds will weaken this evening behind the cold front and winds will veer to northwest.Though winds will be lessening, a higher wave field is expected along the south shore of Lake Ontario through Thursday with another round of small craft advisories possible.

BUF WATCHES/WARNINGS/ADVISORIES. NY . None. MARINE . Small Craft Advisory until 10 PM EST this evening for LOZ043>045. Small Craft Advisory until 6 PM EST this evening for LOZ042.
