JAMESTOWN – The first snowfall of the season will be likely across portions of the Southern Tier overnight as moisture from Zeta collides with incoming colder air.

Tropical Storm Zeta is now located over the northwestern quadrant of North Carolina but its moisture extends well northward of the central circulation. Rain has been moving south to north through Western New York and Northwestern Pennsylvania as Zeta continues moving northeast at a rapid pace. Colder air coming in from the north and west will collide with the tropical moisture and bring the region its first snow of the season with some accumulation possible.







Rain showers will transition over to a mix of rain and snow showers, becoming all snow across the higher terrain of the eastern Southern Tier. Lows 30 in the valleys, 37 at the Lake Erie shoreline.

Early snow showers on Friday will taper off for the afternoon with a chance for a spotty rain or snow shower. Overall total snowfall will be quite minimal across the western Southern Tier with nothing more than a grassy accumulation. Spots on the hills east and south may receive up to two inches.













Temperatures on Friday will be quite cold as well. Highs 35 to 43.

High pressure will make a brief return on Saturday with a good supply of sunshine. Highs 43 to 49.

Saturday night is looking great for any safe Halloween festivities you may have planed. Mainly clear with temps in the lower 40’s, dropping to the mid 30’s by morning.

The next chance of rain will return on Sunday with a storm system passing to our north. Depending on the amount of cold air the system has to work with, there could be some pockets of wintry mix as well. Highs in the upper 40’s.

As colder air rushes in behind the system, scattered snow showers will be possible Sunday night through Monday. We won’t rule out the chance for a couple lake effect snowflakes to develop off the eastern end of Lake Erie. Cold. Highs in the lower 30’s.

Partial sunshine on Tuesday with scattered rain and snow showers at times, mainly in the morning and early afternoon. Highs in the lower 40’s.

High pressure settles back in across the region on Wednesday with mostly sunny skies and milder temps in the lower 50’s.
