Strong Winds and Frigid Temperatures
Wind chill values Monday morning range between -20 and -30 degrees for most of the Finger Lakes.
That will counteract the marginal warming that takes place as temperatures rise from anywhere from 0 to -10 degrees this morning to the mid and perhaps upper single digits this afternoon.
Wind chill values will remain well below zero. Frostbite on exposed skin will occur in 30 minutes or less.
Blowing snow will continue to create near white out conditions in open rural areas with significant drifting. With the frigid temperatures, rock salt will be ineffective, so even main roads will remain messy.
Lake effect snow will linger throughout the day but will be light. At most, an inch or two will fall, mostly near Lake Ontario and just south-southeast of Cayuga Lake, where some Finger Lake Effect snow off Cayuga Lake may develop this evening.
Winds will drop after sunset but will still gust over 20 mph at times through the night, especially towards Central New York.
Breezy Tuesday, Next System Wednesday
After light winds Tuesday morning, another blustery afternoon is ahead as winds turn to the south and increase. Gusts once again could reach 30 mph, especially over higher elevations Tuesday evening.
Tuesday will start with sun and a few early lake effect clouds before a deck of thin clouds high in the atmosphere move in.
Where lake clouds hold overnight, namely east of a Rochester to Elmira line, temperatures will manage to stay jut above zero for Tuesday morning. Further west, where skies clear, temperatures will range from just under zero to ten below.
With the south wind and sunshine, temperatures will top out in the upper teens and low 20s. Additional warming is likely Tuesday night with a range from the mid 20s to low 30s Wednesday morning.
Precipitation will spread from west to east during the morning hours Wednesday. A few pockets of ice are expected, especially towards Central New York. Most of this system, however, will fall as rain as temperatures reach the low 40s.
Rain will taper to showers Wednesday evening only to pick up again by Thursday morning. Rain will turn to snow during the day with a couple inches of accumulation possible.
Temperatures will dive again towards the weekend, bottoming out on Saturday with sub-zero morning lows and highs only in the teens. Some lake effect snow showers will be possible Friday and Saturday with a more widespread light snow on Sunday.
