JAMESTOWN – Clouds will be on the increase over the next couple of a days ahead of a very windy Friday. A High Wind Watch is active for Chautauqua County, going into effect 8 p.m. Thursday and running until 8 p.m. Friday. There is also the potential for the first snowflakes of the season by the weekend.
After morning and early afternoon sunshine, clouds will thicken up through the day, possibly ending the day with partly to mostly cloudy skies. Highs will range 62 to 67, falling to the upper 50’s by late in the afternoon with advancing Cold front.
Mostly cloudy overnight tonight with a small chance for a spotty shower. Lows 45 to 51 with a light west-southwest wind.
More clouds than sun through the day on Wednesday with a chance for a spotty afternoon shower. Cooler with highs 54 to 61.
A deep storm system will pass through the upper Great Lakes and bring us a widespread soaking rain potential on Thursday. Unfortunately for the Trick Or Treaters, this will likely end up being an all-day kind of rain, with moderate to heavy downpours at times.
Current model guidance is suggesting upwards of an inch of rainfall through Friday, maybe even getting close to an inch and a half in spots.
The winds will gradually pick up in intensity throughout the day, becoming their strongest during the overnight hours, into Friday. Wind gusts could reach upwards of 60 MPH, with the overall strongest winds near the Lake Erie Shoreline.
As the center Low moves north into Canada, colder air will wrap around the back edge of the storm Friday and Saturday, bringing the potential for some wet snowflakes along the higher terrain of the Southern Tier.
However, that snow chance is still not a guarantee at this time and there is the chance it could be just a plain, cold rain across the region.
We will continue to fine tune this forecast as we go throughout the week.
