Your Cortland County weather forecast for Friday, February 19, 2021:
Snow associated with a continued winter storm will transition to lake effect snow later today.
While the main part of the winter storm will stay far from Cortland County, on and off periods of snow will continue this morning and into the afternoon.
Additional accumulations around an inch are possible this morning, but temperatures will rise this afternoon, making accumulations tough to come by.
The warmer air will come in via south and southwest winds at around 5 mph. These winds will develop this morning and continue into the mid afternoon, driving temperatures into the low 30s.
Later, the winds will turn to the west and northwest, dragging cooler air back into the region. Temperatures will drop back into the 20s this evening, ending up in the low 20s overnight.
The colder air coming over Lake Ontario will lead to a few bouts of flurries and squalls this evening and overnight. The lake effect will remain rather disorganized though, so there will likely be plenty of dry time, too.
New accumulations after sunset will be on the order of one or two inches for most areas, but locally a bit higher if a persistent snow band sets up.
Here is a look at the weather for the next several days:
Saturday: Lake effect flurries and squalls. Another 1-4 inches of accumulation. Morning lows around 20. Afternoon highs in the mid 20s.
Sunday: Mostly sunny. Morning lows in the low teens. Afternoon highs in the upper 20s.
Monday: A band of late morning or early afternoon snow. Morning lows in the upper teens. Afternoon highs in the low 30s.
Tuesday: A few snow showers, possibly mixing with some rain. Morning lows in the upper 20s. Afternoon highs in the mid 30s.
