High Pressure Gives Way

The Finger Lakes region is caught in a southerly flow from high pressure along the coast of the Carolinas toward low pressure north of the Great Lakes.

For today, the high pressure will have a greater influence. Skies are clear to start the day and will remain sunny much of the time.

Some thin clouds will eventually mix in with the blue skies. These will not block much sunlight at first, but may become thick enough late in the afternoon to filter some of the sunlight.

A steady south-southwest wind will blow at speeds up to 10 mph during the day. Around sunset, the wind will increase to 10-15 mph before dropping under 10 mph around midnight.

Afternoon highs today will be 10 to 15 degrees warmer than yesterday with most areas in the mid and upper 40s.

Skies will be mixed through the night with an overall increase in cloud cover during the overnight period. By sunrise Friday, it should be mostly cloudy with a few stray showers possible.

Overnight lows will mainly be in the mid and upper 30s, though a few cooler pockets across the Southern Tier and Central New York are likely.

Widespread rain will move in late Friday morning and into the midday hours. The rain will fall steadily through the afternoon, tapering to showers around sunset. Only some drizzle and spits of rain are expected Friday night.

Weekend, Next Week’s Weather

Friday’s system will leave behind a stalled out frontal boundary. On Saturday, a small area of low pressure will travel along the front, bringing some scattered rain showers throughout the day.

The exact location of this boundary will determine how warm it gets on Saturday. If the boundary lifts north towards Lake Ontario, highs in the Finger Lakes could poke into the low 50s. If the boundary is a bit further south and overhead, 40s are more likely.

The boundary will become poorly defined by Sunday, but what is left of it should sink to our south. A stronger low will travel along the boundary late Sunday into Sunday night. Rain should increase across our area late in the day.

A major question will be whether enough cold air gets pulled into the system to turn the rain to snow Sunday night into Monday. At this time, the chances for widespread accumulating snow look to be under 50 percent, but it is something to keep an eye on.

Whether rain, snow, or a mixture, the precipitation will wind down on Monday early in the morning. Scattered rain or snow showers off Lake Ontario will be possible through the afternoon with little impact.

Relatively quiet weather is expected for the middle of next week, though temperatures will be cool again with highs in the 30s.

At least slightly warmer temperatures will be possible toward next weekend, followed by another cool down toward the middle of the month.
