JAMESTOWN – We’re getting set for potentially the first snowflakes of the season come later in the week as colder air battles with the remnants of Zeta which will past to our south and east.

The rain has tapered off for now but showers will be returning to the region overnight as moisture moves in from the south and spreads northward through the day on Thursday. Colder air will push in from the north and west and change some of that rain over to wet snow by Friday morning with light accumulation possible.

Partly cloudy skies will take us through the evening with clouds thickening after midnight. Scattered showers will redevelop towards morning. Lows 36 in the valleys, 45 at the Lake Erie shoreline.

Scattered showers will be common place Thursday morning increasing to more widespread coverage for the reminder of the day. There could be some localized pockets of moderate rainfall at times. Highs 41 to 48.

As the remnants of Hurricane Zeta begin to move closer towards the area, it will be met with a push of incoming colder air from an upper-level trough. The colder air will allow for a changeover to wet snow along the eastern Southern Tier with a wintry mix elsewhere. Lows 27 to 34.

Rain and snow showers will continue in scattered nature on Friday morning before tapering off for the afternoon. We’ll keep a chance for a spotty rain or snow shower throughout the day however.

Accumulations will be very minor. Most across the lower elevations may have a grassy accumulation while spots on the highest hills eastward may get close to one inch of wet snow. Very cold. Highs in the mid 30’s.

High pressure will return for the first half of the weekend leading to a nice but chilly Halloween. Mostly sunny with highs in the mid 40’s.

As another trough moves in on Sunday, that will increase the rain chances once again with highs in the upper 40’s.

Cold air moves back in for next week with rain and snow showers possible both Monday and Tuesday with highs in the lower 40’s.
