Pattern Changing

High pressure will move through the region today, triggering the start of a warming trend.

This high pressure system extends from Michigan to North Carolina this morning, putting our region on the cool, front side.

Temperatures will still be well below average today, but the sunshine will help dig us out of the near-record cold we have been having.

After a frosty start, temperatures are already on the rise. By noon, temperatures should be above 45 degrees, even in the higher elevations. Most areas will then top out in the low 50s this afternoon.

Clouds will be scarce to non-existent and winds will be gentle from the northwest before turning calm late.

The clear skies and light winds will set up another cold night, but it should not be quite as cold as the last few nights. Lows will range from 30-35 degrees.

Patchy frost should still be expected with a few localized pockets experiencing a freeze. Frost and freeze alerts will likely be issued by the National Weather Service later today.

Winds will turn to the south overnight and a few thin clouds will move in. Thursday will start sunny, but clouds will continue to increase, especially in the afternoon.

What sun there is, combined with the south winds, will finally push temperatures into the mid 60s.

A round of showers will move through during the afternoon, followed by on and off rain and thunderstorms through Thursday night. A few heavier downpours will be possible. Overnight temperatures will stick near 50 degrees.

Friday will be a rainy day as the same weather system slowly works through. A few rumbles of thunder cannot be ruled out in the afternoon, especially east of Seneca Lake. Highs will be well into the 60s despite the clouds and rain.

Weekend Weather & Beyond

Saturday will dry out behind Friday’s system. Clouds will mix with some sunshine and winds will be light.

High temperatures will again reach the mid 60s during the afternoon after temperatures start in the upper 40s.

Sunday will be similar to Thursday, starting with some sunshine before ending with some rain. Temperatures will depend on how quickly the rain moves in, but should be able to get into the low 60s.

Scattered rain showers will continue into Monday, probably keeping temperatures in the upper 50s. That weather system will finally pull out early Tuesday, allowing for some afternoon sun and highs around 60 degrees.

Wednesday next week will also be around 60 degrees before an even bigger push of warm air surges north. Highs late next week should push into the 70s.

Temperatures should remain at or above average through next weekend and into the week thereafter.
