JAMESTOWN – As we have been talking about for much of the week, the first frost of the season will likely occur tonight across the Southern Tier and Northwestern Pennsylvania. Temperatures will continue to remain seasonable through much of the upcoming week.
Any drizzle early this afternoon will taper off through the day with some limited peaks of sunshine before the end of the day. Highs will range 45 on the highest hills to 58 near the Lake Erie waterfront.
The National Weather Service has issued a Frost Advisory for Chautauqua, Cattaraugus, and Warren Counties, going into effect Midnight tonight until 9 a.m Saturday morning. There is a Freeze Warning in effect for Allegany County, also going into effect at Midnight and lasting through 9 a.m. tomorrow morning.
As temperatures slip back into the mid to lower 30’s tonight with clearing skies, that will be the prime environment to allow patchy frost to develop in western areas away from Lake Erie, with frost becoming more widespread the further south and east you go.
This will will effectively end the growing season across much of the region. If you have any tender vegetation that is sensitive to frost, bring them indoors tonight or cover them up to prevent damage.
Temperatures will rebound into the lower 60’s Saturday afternoon with plentiful sunshine.
A Warm front moving towards the region will spike temperatures near 70 and bring the chance for scattered to widespread showers. The winds will also increase through the day with wind gusts possibly near 35 MPH at times in the afternoon.
Behind that Warm front, like clockwork, another Cold front will moves through on Monday and trigger off a few more showers throughout the day with highs in the lower 60’s.
High pressure builds back into the region on Tuesday and brings a nice stretch of dry and sunny weather next week with seasonable temperatures in the mid to upper 60’s.
