Frost Advisories Saturday Night

A weather system is moving through the Finger Lakes early Saturday morning with rain showers and more chilly air.

As of 7 am Saturday, the bulk of the precipitation with this system has already fallen in the Finger Lakes. Precipitation will continue to move off to the east this morning and rain will become more spotty.

In the wake of this system, some lake effect rain showers will develop southeast of the Great Lakes. This will keep the chance for a scattered shower across the region into the afternoon.

Between these spotty showers, the sun should start to slowly work out as high pressure builds in from the southwest.

High temperatures will be similar to Friday, with most places between 45-50 degrees.

Lake effect activity should shift to the north tonight, allowing skies to become mostly clear over the Finger Lakes.

Conditions will be favorable for cooling, but there are a couple of factors that should put a limit on how cold it will be.

First, some high, thin clouds will work in overnight. Secondly, a very light south to southwest wind will develop.

Still, even with these factors in play, widespread mid and upper 30s are likely overnight with low 40s right along the shores of the Finger Lakes. Patchy frost is expected, with all counties in the Finger Lakes except those along Lake Ontario under frost advisories.

Typically colder areas will be the most prone to seeing frost.

If you have plants you would like to save, be sure to cover them or bring them indoors.

Nice Sunday Before More Active, Cool Weather

Sunshine mix with some thin clouds is expected for much of Sunday.

As high pressure sets up off the coast of New England, the south wind will continue to develop. It will be a pleasant breeze though, with top gusts under 20 mph.

The sun and wind should help temperatures rebound quickly Sunday morning. By the afternoon, we will only be a few degrees shy of the seasonal normal.

Look for highs Sunday afternoon to range from the mid 50s, mostly across the Southern Tier, to the upper 50s, especially north of I-90.

The nicer weather will not last, however. A new system will quickly move in and by sunrise Monday, rain showers will be back in the area.

Monday will be showery with on and off rain. South winds will keep temperatures up, though, with highs near or just above 60 degrees.

Cold air will move back in behind this system with some lake effect showers and/or patchy frost again Tuesday morning.

Another front moves in Wednesday with some scattered light rain. Lake effect behind this system could be a mix of rain and snow.
