Marine Weather and Tide Forecast for Geneva, NY

NEAR TERM /THROUGH THURSDAY/

630 AM Update:

Lake effect snow showers have been consistent over Broome and Tioga counties this morning. Overnight, 1 - 2 inches fell and localized amounts of up to another inch will be possible in the next couple hours around the greater Binghamton area. An SPS for Broome and Tioga County has been issued through 8 AM this morning due to slick travel on back roads this morning, but main main roads are mostly clear at this time based on webcams across the area.

330 AM Update:

Northwesterly flow continues to push lake effect snow showers into the Finger Lakes Region and as far south as the Southern Tier this morning. Lake effect snow will remain fairly light through most of the day with a brief lull for Onondaga County.
However, another organized lake effect will likely develop this afternoon as the flow starts to turn westerly once again. This shift in flow will allow the lake effect snow to shift back to the north through the NY Thruway corridor and then eventually back into portions of Oneida County. However, the bands of snow will be on a weakening trend. By tonight, weak ridging will move in and allow for any remaining lake effect snow showers to dissipate or at least shift north of our region.

Due to no more heavy lake effect snow expected in Northern Oneida, the warning has been cancelled with this update. All other winter weather headlines remain intact.

On Thursday, a weak clipper system will push into the region, however it is pretty moisture starved. Temperatures will remain cold and spotty snow is expected, but amounts will be light, with less than an inch for most areas.

SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/
330 AM Update...

Short wave trough continues to move through the region Thursday night with lingering snow showers. Showers will be spotty in nature as feature is moisture starved. Temperatures under the trough will continue to remain cool with overnight lows in the teens. Trough makes an exit by Friday morning with an upper level ridge starting to build in. Despite this westerly flow holds through at least late morning. As a result lake effect showers will attempt to form east of Lake Ontario, but model soundings begin to unzip as drier air moves in. Otherwise majority of the area will be precip free Friday through the overnight period. Southwesterly flow and warm air advection settles in by late afternoon with temperatures warming into the low to mid 30s. Similar pattern continues overnight with temperatures in the upper teens to mid 20s.

LONG TERM /SATURDAY THROUGH TUESDAY/
330 AM Update...

Ridge slides east Saturday morning with a broad upper level trough engulfing most of the country. As this trough moves in, southwest flow continues on the back side of the exiting ridge. This will allow temperatures to climb into the low to mid 30s once again. a surface cold front associated with low pressure over northern Quebec approaches from the west. A mix of rain and snow showers is expected to move into the area, especially during the afternoon before transitioning back to all snow showers Saturday night as winds switch back to the northwest.

Broad upper level trough continues to dive further into the country as the weekend progresses as well as into the early week. This will allow much cooler Arctic air to spread into the region with 850 mb temperatures ranging from -22 to -25 degrees C. Monday could see high temperatures in the teens, while Tuesday highs may only get into the single digits. Overnight lows Monday and Tuesday are forecasted to be below zero. This surge of cold air will help kick off more lake effect snow showers over central NY, made sure to blend Canadian NH for pops.
