High pressure centered along the East Coast will keep our weather quiet into the early Tuesday. Meanwhile, a storm system centered over Minnesota is bringing blizzard conditions to parts of the northern Plains while in the lower Mississippi Valley severe thunderstorms and tornadoes are the issue. This system is headed east.
Low pressure to our west will track east into the Great Lakes Tuesday and drag a cold front into western New York. That will bring a mix of precipitation into central New York during the afternoon. Temperatures in the lower elevations will warm close to 40 degrees which means places like Syracuse will see mainly rain showers. Over higher elevations south of Syracuse and the Tug Hill it will be some snow, perhaps even a light accumulation.
Once the cold front passes to our east, colder air will filter back into Central New York, changing any leftover rain/snow to all snow before ending Tuesday evening. Even colder air will eventually arrive Wednesday on the heels of brisk west winds. Those westerly winds mean some heavy lake effect snow is possible east of Lake Ontario. Lake effect snow watches are up for Jefferson, Lewis and Oswego counties. However, winds are forecast to shift into the northwest later in the day and bring lake effect snow showers/squalls into the Syracuse area later in the day or evening. It’s a little up in the air at this point as to how strong the squalls will be by the time they get to Syracuse. The other big story for Wednesday outside the lake effect will be the strong winds. We could see gusts past 30 mph
Our wind flow remains out of the northwest Wednesday night into early Thursday. That means weakened lake effect will be persistent in and around the Syracuse area. Once the lake effect ends Thursday it will just remain chilly by late February standards.
A whole new storm system pulls out of the middle part of the country for the end of the week put it will be weakening as it does. At this point any rain or wet snow that moves in from this system starting late Friday into Saturday will be fairly light in nature.
