Say goodbye to the warm air that’s been over us for the past week or so. As the jet stream dips southward over us this weekend, it will deliver cooler air to our area. Temperatures will end up well below normal by the end of the weekend. The leading edge to that cooler air, a cold front, is responsible for periods of rain that we’ll see overnight.
With the cold front moving through Saturday morning, we do run the risk of some light rain or drizzle early in the day. As this front moves east, the rain will come to an end but clouds will be a bit more stubborn. Some sun could break out late in the day for a few lucky folks.
The air over us Saturday will be cooler than we’ve seen in a while, but a reinforcing shot of even cooler air will arrive Saturday night as a second cold front moves through central New York. The change to this next cool air mass will be signaled by a gusty west northwest wind on Sunday. It may be dry to start Mother’s Day but as the coldest air aloft approaches us later in the day our clouds will build and there may be a few scattered afternoon showers.
A note to people who want to get out on the boat Sunday. It’s best that you stay on land. Waves on the east end of Oneida Lake could approach 3 or 4 feet and waves of 10 feet or more are possible on Lake Ontario by Sunday afternoon.
As the coldest air moves in Sunday night and early Monday, it will be just cold enough for some snow to mix in over higher elevations. During the day Monday our temperatures will be almost 20 degrees cooler than normal for mid May as it will be a struggle to get beyond 50 degrees.
Thankfully, this cold air will begin to pull out on Tuesday. A push of warmer air heads our way by midweek. As it does, though, we will run the risk of a new round of showers and thunderstorms.
