Unsettled weekend ends with snow and wind

Rain and snow showers

A broad area of low pressure is situated north of the Great Lakes and will move little over the coming days.

Bundles of atmospheric energy rotating around the low will keep the weather unsettled for the next few days.

This morning, the Finger Lakes region is between areas of active weather. Skies are a mix of sun and clouds and precipitation is limited to one or two isolated showers. Temperatures are in the upper 30s and low 40s.

Off to the west, a large area of clouds will build eastward through the morning and into the early afternoon. Before the clouds become too thick, temperatures will have a chance to reach the upper 40s during the early afternoon hours, mainly across the eastern half of the Finger Lakes.

Winds will be from the southwest, increasing to speeds near 10 mph and gusts around 25 mph. These will not be warming southwest winds, though.

Temperatures will drop this afternoon, mainly into the low and mid 40s, as the clouds move in and scattered rain showers develop.

The rain will be off and on through the second half of the afternoon and into the evening hours. Temperatures will continue to fall, and the rain will mix with and turn over to snow during the overnight. Only a coating on grassy or elevated surfaces and parked cars is expected.

Much of Saturday will continue to have on and off scattered precipitation. Snow showers may be most common early on, but rain will become the dominant precipitation type during the midday and afternoon.

Temperatures should work their way back to the mid 40s Saturday afternoon. Winds will be lighter, with speeds under 10 mph coming primarily from the west.

Snow and Wind

Another weather system will dive southeast around the larger low on Sunday. Originating from Canada, this system will bring colder air and strong winds into the region.

Snow showers will spread across the area Saturday night as winds turn to the northwest and increase. Wind speeds of 10 to 15 mph will be in place by sunrise Sunday and will persist through the day. Wind gusts will range from 25 to 35 mph.

The widespread snow showers will transition to a spray of lake effect by Sunday afternoon. Localized heavier bands will be within this spray of snow showers.

Temperatures throughout much of Sunday will hover in the low and mid 30s. These temperatures should limit some of the snow accumulation, but localized areas could still manage an inch or two during the daytime hours.

Evening temperatures will quickly fall through the 20s with 10s becoming widespread by midnight. The lake effect will probably become better organized and accumulations will be easier to come by.

Where the bands set up, several inches may fall Sunday night. Outside of the bands, accumulations will be minor. Blustery winds will continue, leading to blowing and drifting snow.

Monday morning, the snows will gradually wind down. At least some flurries will probably linger into the afternoon, though. Winds will increase further, with gusts of 35-45 mph, still from the northwest. Blowing snow will continue even after the lake effect winds down.

Temperatures will be well below average with highs in the low and mid 20s.

Tuesday will be quiet with increasing sunshine. Temperatures will start to rebound but will still be limited to highs in the low 30s.

A warm front will move through sometime on Wednesday. A period of precipitation is likely, but what type falls is still highly uncertain. Warmer air will move in for a day with highs Thursday possibly returning to the 60s.

Cooler air seems likely to move right back in, likely with unsettled conditions. There is certainly a possibility for more snow after this weekend given the pattern, though it is not a guarantee.
