Area Forecast Discussion National Weather Service Buffalo NY 1000 AM EDT Tue Sep 28 2021

SYNOPSIS. High pressure will build into the Lower Great Lakes in the wake of the cold front today which will promote fair and dry weather for most areas for much of the week, but cool conditions.

NEAR TERM /THROUGH WEDNESDAY/. In the wake of last nights cold frontal passage . high pressure centered over the Upper Great Lakes will drift north to James Bay while taking firm control of our weather. This will lead to abundant sunshine today . although clouds will still need to clear out across the srn Tier. It will be cool with temps in the 60s.

After a patch of alto-cu moves through late this afternoon and evening . we can look for mainly starlit skies tonight. The exception could be from about KROC to near KSYR where some nuisance lake induced strato-cu may develop.

Wednesday will feature another fair but cool day with at least partial sunshine. Areas east of Rochester will likely experience some self destruct sun with an isolated shower or two from subtle shortwaves rotating south into the region interacting with diurnal instability. Remains on the cool side of normal.

SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/. Cold advection continuing Wednesday night into Thursday with 850 mb temperatures dropping to near 0C. Certainly cold enough to see lake effect clouds and at least some spotty lake induced showers south and southeast of Lake Ontario.

Core of the coldest air aloft start to shift east Thursday. Any lake clouds and light showers south of lake Ontario will slowly wane by afternoon.

Skies will clear out over much of the area Thursday night as high pressure buildings in. Should be a chilly night away from the lake plains with interior sections of the Southern Tier and east of Lake Ontario getting down into the 30s, with the potential for some patchy frost.

LONG TERM /FRIDAY THROUGH MONDAY/. To close out the end of the work week and start of the weekend, model consensus has an upper level low to wobble across the Canadian Maritimes. As the weekend progresses, a few waves of energy will pivot around the cyclonic gyre before pulling northeast early in the next upcoming work week. However, the model guidance packages continue to hold differences in timing and placement of the waves of energy. Overall, this translates to mainly dry weather Friday, before slight chances for showers enter the forecast for each day of the weekend due to the upper level energy pivoting across the area.

Otherwise, cool temperatures will continue throughout the end of the work week, weekend and start of the next week. Highs Friday through Monday will range in the 60s, with lows dropping into the 40s Friday night and upper 40s to low 50s throughout the weekend.

AVIATION /14Z TUESDAY THROUGH SATURDAY/. MVFR to IFr cigs across parts of the Srn Tier through about 16z . otherwise fair VFR conditions expected through tonight.

Outlook .

Wednesday through Saturday..Mainly VFR.

MARINE. A brief period of 15-25 knot NNE flow will persist behind the cold front producing a period of very choppy conditions along the south shores of Lake Ontario and Lake Erie. Conditions will briefly reach Small Craft Advisory levels for several hours on each lake, especially Lake Ontario. Winds and waves will then diminish later this morning into this afternoon. Small Craft Advisories have been issue from the Lower Niagara River to Mexico Bay through 17Z.

Winds and wave action expected to become light tonight and remain that way through Wednesday.

BUF WATCHES/WARNINGS/ADVISORIES. NY . Beach Hazards Statement until 2 PM EDT this afternoon for NYZ003-004. MARINE . Small Craft Advisory until 2 PM EDT this afternoon for LOZ042>044.
