Weathering the Storm: A Comprehensive Guide to Lake Effect Snow Warnings in Western New York

by

As winter descends upon Western New York, lake-effect snow becomes a formidable concern. With the National Weather Service issuing numerous warnings, understanding these climatic phenomena is crucial for locals. Lake-effect snow is created when cold air from the North polarizes over parts of Lake Erie and Lake Ontario. The resultant weather event, usually forecasted for snowy Thursdays, can leave several feet of snow in its wake in areas including Buffalo, Watertown, and Rochester.

Anticipating Heavy Lake Effect Snow

Lake-effect snow warnings usually signify the anticipation of heavy snowfall. Experts measure snowfall intensity in terms of the depth of snowfall expected per hour. These ‘snow-blow’ events can lead to snowfall hazardous conditions, with snow expected to fall at rates of up to three inches per hour. Amidst these snowstorms, hitting speeds of 35 mph can mean whiteout roadway conditions, reducing visibility dramatically. One notorious lake-effect snow event in Dec saw accumulations that could be measured in feet. Snow warnings were in effect from Wednesday evening to Friday morning, signaling that residents in Buffalo and Watertown areas could expect at least 2-3 feet of snow.

Paralyzing Snow: The New York Experience

Such events can paralyze entire sectors of Western and Upstate New York. They are impacting everyone, from professional sports teams such as the Buffalo Bills to residents in Southern Erie, Northern Erie, and Genesee. Even the much-loved regions of Cattaraugus and Chautauqua counties are not spared, with several feet of snow stranding vehicles and inhabitants alike. Forecasters from the National Weather Service in Buffalo continuously update locals about impending weather, employing the latest technology for issuing lake-effect snow warnings. Stay aware, stay safe, and remember – while lake effect snow warnings are undoubtedly an integral part of life in Central New York, measures are in place to ensure your safety. Keep a sharp eye on updates and a sharper eye on the swirling snow globe outside your window.

 Decoding Weather Warnings: Lake Effect, Snow Warning, and Winter Storm Watches

In Western New York, regular reports of lake-effect snow are part and parcel of winter. The forecast often indicates feet of snow are expected, and with that comes warnings from the National Weather Service in Buffalo providing timely updates to brace residents for forthcoming weather conditions. Lake-effect snow is a unique weather phenomenon that occurs when cold air currents pass over warmer lake waters, in this case, Lake Erie and Lake Ontario. This interplay of temperatures can result in heavy snow in parts of Western New York and Upstate New York. Forecasts often anticipate several feet of snow falling, with snowfall amounts occasionally measuring up to three inches per hour.

Interpreting Weather Warnings

On especially snowy Thursdays, warnings are issued to alert regions like Buffalo, Watertown, and Rochester to impending heavy snow. These warnings are paramount as they preclude the potential for hazardous conditions marked by poor visibility, whiteout conditions, and even paralysis of vehicle traffic across roadways. Unpacking weather warnings involves understanding the degrees of severity: Lake effect snow warnings are issued when significant snowfall exceeding two feet is expected. A winter storm watch, however, is a notification to be prepared rather than imminent snowfall. And when the snow warning is in effect, residents should expect immense accumulation over a short period.

Navigating Lake-Effect Snow Alerts

For instance, the December lake effect snow event resulted in several feet of snow, with areas such as Southern Erie, Northern Erie, and Genesee facing adverse conditions. The buffalo area and surrounding counties like Cattaraugus and Chautauqua were significantly affected.

Regularly issuing weather warnings is a stark reminder to remain vigilant to the latest updates and forecasts. Western New Yorkers understand that the beauty of the snow globe outside tonight could give way to practical challenges tomorrow morning. Rest assured, the National Weather Service is dedicated to ensuring the public stays informed, prepared, and safe.

Lake effect snow is a phenomenon that occurs downwind of large lakes like the Great Lakes in North America, resulting in increased localized snowfall during the late fall and winter months. When cold, arctic air moves across the relatively warmer waters of the lakes, it picks up moisture and heat, adding humidity and warmth to the air. As this now warmer, moister air reaches land on the downwind side and moves inland, the air rises, cools, and condenses, forming clouds and precipitation. Since the air coming off the lakes is extremely cold, the moisture often falls as heavy bands of snow rather than rain. The air cannot hold much moisture, so a lot of it is released as snowfall. This is why cities downwind of the Great Lakes such as Buffalo, Syracuse, and Cleveland can get far more snow than other areas at the same latitudes. The lake moisture provides extra water vapor to be turned into snow, while the lakes themselves create an unstable environment for lift, allowing heavy snow bands to form. In summary, lake effect snow is a localized phenomenon that occurs downwind of large lakes during cold months, resulting in narrow but intense bands of very heavy snowfall, especially across portions of the Upper Midwest and western Great Lakes region. The lakes provide instability and added moisture to enhance snowfall rates and totals in these areas.

Here are the main criteria that need to be in place for heavy lake effect snow to occur:

  • Cold air: There needs to be a large temperature difference (at least 23°F/13°C) between the surface of the lake and the air above it. This allows the warm lake water to add heat and moisture to the air.
  • Wind direction: The wind over the lake needs to blow roughly perpendicular to the longer axis of the lake, which maximizes the amount of open water area the air flows over. This allows the air to pick up as much moisture as possible.
  • Wind speed: Winds of at least 15-25 mph are required to generate enough turbulence to pick up moisture and initiate snow bands. However, winds over 35 mph can disrupt snowfall.

-fetch: This refers to the distance the air travels over open water. Longer fetch provides more opportunity for moisture uptake and instability.

  • Upper level support: Divergence aloft and vorticity in the upper levels of the atmosphere help enhance lift to the air parcel and perpetuate bands.
  • Upwind land: Having an unfrozen, snow-free land upwind prevents the air from being modified before moving over the lake.
  • Instability: The temperature difference between the lake surface and air above combined with convergence creates convective instability ideal for snow bands.

So in summary, the key ingredients are cold air mass, significant lake-air temperature difference, perpendicular wind direction, adequate wind speed, instability and moisture supply. When all these criteria are met, narrow snow bands can erupt and drop feet of snow downwind of Great Lakes.

The main difference between regular snow and lake effect snow is the localized intensity and amounts of lake effect snow due to the influence of large nearby water bodies.

Regular snow falls from frontal systems and winter storms that can impact large regions with more uniformly distributed snowfall. Lake effect snow occurs when very cold, arctic air passes over the relatively warm waters of the Great Lakes, providing instability and moisture to focused, narrow snow bands that dump incredible amounts of snow in small areas downwind of the lakes.

While a regular winter storm may blanket an entire state with 1-6 inches of snow, a lake effect event can bury specific locales right along the lakeshore with several feet of snow just over the course of a day or two. The snow piles up rapidly and can paralyze areas of the Great Lakes region. This is because the open lake waters provide a moisture source and upward lift that concentrates in localized bands and enables extreme snowfall rates.

Lake effect snow occurs during the late fall through early winter months, typically November through February in the Great Lakes region, with December and January being the peak months. As winter sets in, arctic air moving over the still relatively warm lake waters creates ideal conditions for lake enhanced snowfall. November starts the season, though lake effect events are usually sporadic initially. December sees cold air outbreaks increase as the Lakes remain warm, with frequent and heavy snow squalls downwind. January is often the height of lake snow, with the combination of very cold air and warm lakes leading to high instability and moisture supply. February continues to be quite active, though lake effect starts to wane as the lakes slowly lose their heat. March sees the snow bands become more intermittent as ice cover spreads. By April, the Lakes are too cold to generate much snow. So the core months when all the ingredients align – from early cold air moving over warm lakes – are November through February, with a peak from mid-December through January.
