Tonight: Partly cloudy and very cold. Low 15
Sunday: Increasing clouds. High 29
Sunday Night: Light snow likely in the evening followed by light sleet and freezing rain for the overnight. Up to an inch of snow accumulation possible. Low 26
Through the evening and overnight period expect partly cloudy skies with very cold conditions. Lows will dip down into the lower to middle teens. A light breeze will create wind chills near zero.
During the day on Sunday clouds will be on the increase well out ahead of an approaching storm system. A low pressure will eventually move into southern Ontario by Monday morning along with another area of low pressure will form off the coast of North Carolina. In the meteorology world, we call this a double-barrel low pressure system. The Twin Tiers will be right in between these systems therefore precipitation will be low. It will remain dry during the daylight hours on Sunday but by the evening the chance for some light snow moves in southwest to northeast. The light snow will change over to light sleet and freezing rain during the overnight. Up to an inch of wintry precipitation is possible. The roads may be slick early Monday morning. Late in the morning on Monday, any wintry precipitation will change over to light rain showers as temperatures rise above freezing.
The rest of the week, arctic air will settle into the area. Tuesday and Wednesday will feature the slight chance for a few flurries with highs in the mid to upper 20’s. Thursday and Friday look dry with partly sunny skies and highs in the low to mid 20’s.
