Another weak system brings light snow today

Snow Showers

A small weather disturbance is moving toward our region from the west this morning and will keep light snow showers in the area throughout the day.

This disturbance is associated with a weak low pressure system north of Lake Superior over Canada. With the low expected to track north, and then northeast, it will never have an opportunity to bring cool air into the region.

Instead, temperatures will remain fairly steady today, rising just a few degrees to highs in the mid 30s, then falling tonight back to around 30.

It will be cloudy throughout the day with on and off snow showers. Some periods of steady light snow are likely, but it will not amount to much. Total accumulations should remain under an inch. A few higher elevations may manage to get around an inch.

The steadiest snow should taper off during the latter half of the afternoon with a couple hours of mainly dry conditions early this evening. By 8 or 9 PM, additional snow showers will move in. A few of these may be briefly heavier, but there is also a chance for some rain to mix in over the warmer area.

Winds will be from the southwest all day and into the first half of the overnight. Wind speeds will be around or just over 5 mph. After midnight, winds will turn to the west and increase to around 10 mph.

Southwest winds will take back over Wednesday morning. Despite a rather cloudy day, temperatures will climb to the upper 30s with some areas sneaking to or above 40 degrees.

Temperatures Wednesday night will initially drop to the low 30s before rising back toward 40 degrees before the sun rises Thursday.

Remaining Unsettled

Another system will move into the area on Thursday. Precipitation will move in by sunrise Thursday as the temperatures are rising. A few areas could see a little snow at first, especially in the higher elevations of Central New York.

The majority of this system will be rain, though, with on and off rain showers throughout Thursday. Like today, precipitation will stay light, but may fall steadily for some of the time.

High temperatures on Thursday will reach into the mid 40s but will drop back to around 30 Thursday. The rain will push east during the afternoon, and some limited lake effect snow will develop Thursday night. Winds will be from the northwest, so the northeastern Finger Lakes stands the best shot at some minor snow accumulations.

The lake snows seem unlikely to linger long Friday with increasing sunshine by the afternoon. High temperatures should be in the mid 30s with some breezy winds.

Another system will be nearby on Saturday with a few more snow showers.

There may be a better chance for snow Sunday night into Monday. The models have been hinting at more meaningful weather around this time for many days, so the pattern will need to be watched. At this time, though, it is still too far out for any real speculation on what the pattern may hold.

Cool, unsettled weather will likely persist through much of next week.
