JAMESTOWN – The heat ridge has built in leading to the hottest stretch of weather so far this summer with a few limited chances for showers and storms this week.
A big dome of ridging back to our west continues to pump in uncomfortably hot and humid conditions with the peak of the heat likely arriving on Thursday and Friday of this week. With the high amount of humidity and strong daytime sun, some popup showers and thunderstorms are possible in the afternoon hours virtually each day this week.
Any early showers or storms will go to bed this evening leading to partly cloudy skies overnight with areas of valley fog developing by morning. Quite warm and sticky. Lows 64 in the valleys, 73 at the Lake Erie shoreline.
Wednesday will be a virtual rinse and repeat with lots of sunshine early in the day with widely spaced showers and thunderstorms popping up in the afternoon. Remaining hot and very humid. Highs 84 to 93.
As the the ridge reaches its most intense on Thursday, that will bring in even hotter and even more humid air. Afternoon showers and storms will be possible in scattered nature with baking sunshine. Highs 87 to 96.
The copy and paste weather continue on Friday with highs near 90 once again.
During this period, the main issue will be the heat index or the “feels like” temperature. Heat indicates could potentially reach the mid 90’s on both Thursday and Friday. We would not be shocked if we see a Heat Advisory issues for the Southern Tier by the National Weather Service in Buffalo (a heat index of at least 95 degrees must be met for Advisory issuance per local criteria).
Make sure to stay cool especially during this period and limit your time outdoors if you can.
Heading into the weekend, a weak cold front will move through triggering off a better chance for showers and thunderstorms both Saturday and Sunday along with some needed relief from the heat and the humidity. Highs will go down into the lower 80’s.
We’ll keep a small chance for an isolated or scattered shower or rumble on Monday with some peeks of sunshine in between. Highs in the upper 70’s.
