Open Lake Forecast for Lake Ontario
National Weather Service Buffalo NY
1001 PM EDT Sun Sep 19 2021
For waters beyond five nautical miles of shore on Lake Ontario
Waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. Occasional wave height is the average of
the highest 1/10 of the wave spectrum.
.SYNOPSIS...A 30.2 inch high will remain across New England through
Monday. A 29.6 inch low will cross Ontario Canada on Tuesday, with
an associated cold front slowly approaching the lake on Wednesday. A
wave of low pressure will develop along this front as it slowly

Area Forecast Discussion National Weather Service Buffalo NY 1010 PM EDT Sun Sep 19 2021
SYNOPSIS. Quiet weather will continue into Tuesday as high pressure over New England expands across much of the Great Lakes. Active weather will return by mid-week with the arrival of a trough and cold front.
NEAR TERM /THROUGH MONDAY/. Surface ridge will remain across the Northeast maintaining quiet and dry weather. A bit of a southeast breeze will pickup later tonight especially on the western side of the Chautauqua ridge as the high starts to shift to the east. Otherwise, clear skies tonight will support radiational cooling and support a round of valley fog across the western Southern Tier tonight. Lows tonight will be on the cooler side, with lower to mid 40s across the areas east of Lake Ontario and upper 40s to low 50s elsewhere.
Increasing southerly flow Monday will support warmer temperatures with highs in the lower to mid 80s across the lake plains with mid to upper 70s across the interior.
SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/. High amplitude ridge straddling the eastern seaboard at the start of this period will gradually take on a positive tilt . as anomalously strong shortwaves will feed into and sharpen a deep trough over the mid western states. The result will be a painfully slow eastward progression of developing 150 mile band of moderately heavy rain. Given the tight west to east gradient of the digging trough . there should be a sharp edge to both the more significant cloud cover and resulting rain . but that wont come into play until later Tuesday and Tuesday night In the meantime. fair weather with above normal temperatures will persist.
The ECMWF and NH Canadian have come somewhat into line with the challenging storm evolution over the Mid west . while the GFS remains distinctly too fast with its resultant rainfall and is an obvious outlier. Will throw out the latter without hesitation. The accepted solution is to have a deep closed low develop over the mid west with an inverted trough/wavy frontal boundary easing across Lake Erie to our FAR western counties. This would support more widespread rain (moderately heavy at times) west of the Genesee valley while more showery pcpn would be expected further east.
LONG TERM /THURSDAY THROUGH SUNDAY/. Highly amplified pattern will be in place during the second half of the upcoming week right through next weekend, with persistent troughing in the East and ridging over much of the West. In terms of sensible weather, this will mean unsettled weather overall and more seasonable temperatures with a cooler fall feel to the air.
Overall, guidance continues the slower trend with respect to the eastward progression of large storm system that will impact our region during the second half of this week. GFS remains the fastest, while the still preferred solution advertised by the Canadian NH/ECMWF remains on the slower side of the envelope. Large upper low will lumber northward from the Ohio Valley to the Central Lakes Thursday into Thursday night, before getting 'kicked' well north toward James Bay on Friday owed to the next strong trough digging toward the upper Great Lakes. At the surface a strong cold front will approach then occlude as it slowly crosses the lower Great Lakes sometime later Thursday into Friday, while its' associated surface low mirrors the track of its' parent upper low. Strong LL jet, favorable UL jet placement and strong vorticity advection will provide ample forcing . and when combined anomalous deep moisture advection, will likely produce a period of moderate to heavy rain along and ahead of the boundary as it crosses the region during this timeframe.
Cold front should finally get shoved completely east of our area by Friday night as the next powerful shortwave digs southeast across the upper Great Lakes, also accompanied by a strong surface cold front. Drier and cooler air will settle in toward the end of the work week in the wake of the first boundary, so depending on the exact timing, there will likely be a relatively short window of dry weather between the two systems from sometime Friday into the first part of the weekend. This will only be followed up by the next powerful system (mentioned above) to impact our region next weekend as well. There will again be plenty of forcing in play, however much less in the way of available moisture will really cut down on rainfall amounts and coverage. A reinforcing shot of cooler more seasonable air will also filter across the lower Great Lakes in the wake of this system.
Temperatures will generally be seasonable, with daytime highs later this week into the weekend mainly in the 60s, with some low 70s across the traditionally warmer spots and some upper 50s over the higher terrain at times.
AVIATION /02Z MONDAY THROUGH FRIDAY/. VFR conditions at all TAF sites through 06Z. Patchy valley fog across the western Southern Tier may clip KJHW late tonight. Then widespread VFR flight conditions during Monday.
Outlook .
Monday night through Tuesday . Mainly VFR. Wednesday through Friday . Mainly MVFR with showers likely.
MARINE. Winds will shift to the southeast overnight, but remain on the light side around 10 knots. As the high continues to shift east tonight and Monday, winds will continue to veer and result in moderate southerlies.
