10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Open Lake Forecast for Lake Ontario
National Weather Service Buffalo NY
1230 AM EST Mon Dec 16 2019
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 28.4 inch low over Labrador Canada will remain
nearly stationary today and gradually weaken. Meanwhile, a narrow
ridge of high pressure averaging 30.2 inches will build across the
lower Great Lakes today before low pressure of 29.7 inches moves
just south of the lower Great Lakes and New England by Tuesday. A
29.6 inch compact area of low pressure will drop southward along the
eastern shoreline of the Lake Wednesday afternoon, with a secondary
trough dropping southward across the Lake Wednesday night. 30.3 inch
high pressure will push into the eastern Great Lakes Wednesday night
and Thursday, and drift east of the Lake on Friday.

Area Forecast Discussion National Weather Service Buffalo NY 1231 AM EST Mon Dec 16 2019
SYNOPSIS. Limited lake effect snow will continue east of Lakes Erie and Ontario tonight with minor additional accumulations. High pressure will build into the area and bring an end to the lake effect snow by Monday morning. Low pressure will then pass just south of the area late Monday night and Tuesday with periods of snow producing light accumulations for most of the area. Lake effect snow will develop again by Wednesday, with much colder air arriving for the middle of the week.
NEAR TERM /THROUGH TODAY/. This early morning, strong low pressure down to 966mb drifting over northeast Quebec toward Labrador Canada will allow cyclonic cool westerly flow to remain in place across the eastern Great Lakes. This flow pattern will continue to support limited lake response, but high pressure and associated sub cloud base drying building in from the northern Ohio Valley and central Great Lakes is putting crimp in the lake effect. Regional radars display lingering flurries east of Lake Erie, lifting northward across Ski Country and towards the Boston Hills. Southeast of Lake Ontario, broad lake response is allowing for flurries and light snow showers . with minimal additional accumulation.
On Monday an initial, weak baroclinic wave will move from west to east along a stalled frontal zone stretching from the Ohio Valley to southern Pennsylvania. This feature will spread a period of mid level clouds across our region during the morning and midday, but any precipitation will stay well south of the NY/PA line through the evening. Once any lingering lake effect snow showers end early in the morning, the rest of the day will be dry. Expect highs in the mid 30s in most locations, with 20s limited to Lewis County.
SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/. The jet stream will intensify over the Northeast Monday night while surface low pressure moves across the Central Appalachians. A shortwave trough tracking across the Ohio Valley will follow behind the surface low, further deepening the surface low as it approaches southern New England Tuesday. Strong upper level divergence across the forecast area from a 180kt jet streak and a mid-level baroclinic zone will enter Western and North Central NY Monday night. Light snow will move into Western NY Monday evening and spread north- northeastward overnight. Light snow should encompass the entire forecast region overnight before tapering off in the west Tuesday. At this time, the best forcing remains to the south-southeast of the forecast area and while snow will likely be around for 12-18 hours Monday night-Tuesday, light accumulations of a few inches are expected. The surface low moves off Cape Cod Tuesday afternoon and most of the snow will end from west to east across the forecast area. There will be some lake enhancement moving into Tuesday evening as cold air advection begins. It won't be until late Tuesday night-early Wednesday morning when moisture increases from an upstream shortwave trough and a cold front approaches. This strong cold front will sweep through the region Wednesday morning. Steepening lapse rates with 850mb temperatures falling to -20C across western NY and -22C east of Lake Ontario by Wednesday afternoon will produce extreme lake induced instability. This coupled with moisture increasing from the west will result in snow showers across the region Wednesday. The risk for snow squalls continues Wednesday along and behind the cold front.
Lake effect snow bands will form ahead of the cold front early Wednesday morning northeast of the Lakes and will shift southward behind the cold front. Winds quickly become west-northwest through the afternoon and while it will be favorable for snow squalls, the quick change in wind direction will limit the amount of snow accumulation east of the Lakes. Snowfall accumulations will still likely reach headline criteria but the event will be short-lived off both lakes. Surface high pressure will track across the Ohio Valley Wednesday night and dry air and subsidence will cause inversion heights to come down. Lake snows will slowly come to an end east of Lake Erie late Wednesday night and likely continue southeast of Lake Ontario into Thursday morning.
Below normal temperatures expected during this time with high temperatures in the low to mid 30s Tuesday and Wednesday. Low temperatures will range from the upper teens to low 20s Monday night to Wednesday night. Strong cold air advection and increase in winds will lead to wind chills below zero Wednesday night.
LONG TERM /THURSDAY THROUGH SUNDAY/. The eastern Great Lakes remains on the western side of a departing upper level trough Thursday. Lingering lake effect snow showers will persist Thursday as 850mb temperatures rise through the afternoon. A large scale ridge will move overhead late in the week which will suppress any snow showers and dry conditions expected into the weekend.
Model guidance is in some agreement that a closed low will track across the Lower 48 Saturday-Sunday and initiate cyclogenesis across the southern U.S. This will keep most of the activity well to our south however a northern stream shortwave trough may track across the Great Lakes Sunday-Monday bringing the chance for snow showers.
Temperatures will remain below normal however there will be a slight warming trend through the weekend.
AVIATION /06Z MONDAY THROUGH FRIDAY/. Lake effect snow showers will continue to decrease in coverage the rest of the night, before ending Monday morning. A few snow showers with brief MVFR CIGS may affect ROC and JHW late this evening, but overall expect conditions to stay mainly VFR at all TAF sites. Once the lake effect snow showers end, VFR will prevail Monday with a period of dry weather and some mid level clouds.
Outlook . Monday night . Light snow developing after 06Z with conditions deteriorating to IFR. Tuesday . IFR in light snow. Wednesday . IFR in lake effect snow east of the lakes, with VFR elsewhere. Thursday . IFR in lake effect snow showers southeast of the lakes, VFR elsewhere. Friday . VFR.
MARINE. A strong low over eastern Quebec continues to drift away from the region. Small craft conditions are waning on Lake Ontario from west to east as the surface low pulls farther from the Lake.
Light winds will return today. Another period of stronger winds will develop late Tuesday night and Wednesday as a strong cold front crosses the region. This will bring the next round of Small Craft Advisory conditions to the eastern Great Lakes.
BUF WATCHES/WARNINGS/ADVISORIES. NY . None. MARINE . Small Craft Advisory until 4 AM EST early this morning for LOZ043>045.
