Pattern Shift
A push of warmer air from the Midwest has led to some widespread light snow this morning.
The snow will taper off during the mid and late morning hours, leaving behind minimal accumulations of an inch or less.
Untreated surfaces may be a bit slick early this morning, but as temperatures rise out of the 20s and into the 30s, conditions will gradually improve.
This afternoon, skies will remain cloudy, and a stray bit of snow, rain, or drizzle will be possible.
Southwest winds will make today warmer than yesterday, but the core of the warm air is still yet to come. Look for highs today in the upper 30s.
Skies will remain mostly cloudy tonight, though there is a brief window for some clearing as one batch of clouds departs and another moves in. The new clouds will be thinner and higher in the atmosphere. Overnight lows will be in the mid and low 30s.
Friday will have a mix of sun and clouds. The morning hours will have more clouds than the afternoon, but many of these may be thin enough to allow for some filtered sunshine.
Winds will turn to the south-southeast with speeds just under 10 mph. Afternoon highs will jump to the mid and upper 40s.
The warming will not stop there. Saturday should start with a morning low near 40 degrees and afternoon highs in the low 50s for many. Saturday will be quiet with more clouds than sun and steady south-southeast winds.
Sunday-Monday Weather System
A frontal boundary will press eastward toward our area on Sunday. Further south along this front, low pressure will develop and ride northward, passing near or just east of our area Sunday afternoon.
Rain will first move into the Finger Lakes sometime Saturday night between midnight and dawn Sunday. Some far eastern areas may not see the rain begin until after sunrise.
Periods of rain are likely throughout Sunday, increasing in intensity during the afternoon as the low pressure passes by. It will be a bit breezy, but not too windy, with gusts mainly under 30 mph on Sunday.
The wind will suddenly turn from the south to the northwest as the frontal boundary passes through during the early afternoon. Temperatures will go from the low 50s during the early afternoon to the 30s by nightfall.
The biggest question then is how quickly the precipitation turns over to snow, and how much heavy precipitation will still be lingering over the area.
There is still a large spread in the possible snow amounts, but the most likely scenario is for a couple of inches Sunday night. There are certainly paths to higher amounts, so this bears close watching. There are also paths to little to no accumulation, though.
Winds will pick up on Monday with gusts around or slightly over 30 mph from the northwest. Temperatures will spend the day in the 30s with some scattered lake effect snow showers.
Tuesday looks quiet and a touch milder with highs near 40 degrees and some sunshine. Wednesday may also have a little sun but should see temperatures dip again.
The only other chance for precipitation next week looks to be a few snow showers on Thursday. Temperatures should mainly remain in the 30s through next weekend, though Friday may get a slight boost into the low 40s.
