A sharp drop in temperatures overnight followed the heavy rain that fell and is resulting in an icy morning across the Finger Lakes.
Snow is still falling behind the weather system as well, mostly over the northern and western reaches of the region. This snow will continue to pull out of the area this morning, but some lake effect will develop over the usual areas southeast of Lake Ontario.
The lake effect will last several hours before dissipating during the mid to late afternoon. A couple inches may fall in Cayuga and Onondaga counties.
Stiff northwest winds will persist through the day with speeds of 10-15 mph and gusts up to 30-35 mph. These winds will continue to supply cold air into the region, offsetting any daytime heating. Temperatures will mostly hold steady during the daytime hours, ranging from the upper 10s to the mid 20s.
Some sunshine will be possible to end the day as high pressure slides by to our south. This high will also shift the wind, turning it back to the southwest this evening and to the south overnight. After temperatures drop to the low and mid 10s this evening, they will rise back to the mid 20s by dawn Saturday.
Another front will move through Saturday morning. Snow showers will be possible out ahead of the front, followed by a burst of snow along the front itself. The front should clear the area by noon, with west winds whipping up behind the front.
Wind speeds from the late morning into the afternoon will be near 20 mph with gusts of 40-50 mph. The best chance for 50 mph gusts will be for areas near and west of Canandaigua Lake.
Temperatures will make it to near 30 during the morning before the front but will fall to the low and mid 20s behind the front. This will allow lake effect to develop over Lake Ontario. Late in the afternoon, winds will shift slightly to the northwest, and some of the lake effect will drop south, resulting in another burst of snow, especially for areas near and north of the Thruway.
Wind speeds will drop Saturday evening, and after midnight, the wind will again turn around to the south. Lake effect will be removed from the region and skies will clear.
Temperatures will make it down into the single digits Sunday morning, but then south winds and sunshine will power temperatures upward. Rises of 35 to nearly 40 degrees are expected, resulting in highs ranging from the upper 30s to the mid 40s.
Sunshine will be plentiful through Sunday, though a few thin clouds will be possible here and there. Thin clouds will be more prevalent on Monday, but there still should be a fair amount of sunshine.
Temperatures will continue their climb. Morning lows Monday will be in the 30s and afternoon highs will push into the 50s.
Clouds will thicken Monday night into Tuesday ahead of the next weather system. Rain will hold off until Tuesday afternoon, allowing temperatures to again reach the low and mid 50s.
Rain showers will linger on Wednesday with temperatures remaining in the 50s. Cooler air will work in late in the day, sending nighttime temperatures well into the 20s.
Another weather system will target the area later Thursday into Friday. From this very early vantage point, all precipitation types are still on the table. Stay tuned.
Warm air will be harder to come by behind that system, with temperatures sticking closer to the climatological averages as we head into early March.
