Sunshine Thursday Retreats Friday

High pressure passing through southern Canada will bring a sunny, albeit a bit breezy day to the Finger Lakes on Thursday.

Sunny skies are expected from start to finish today, with only a few small fair weather clouds expected at most.

The wind will come from the north today and will be a bit blustery at times. Wind gusts up to 25 mph will be possible throughout the day.

Temperatures will respond to the north winds accordingly. The Southern Tier will be warmest, with mid and even upper 70s likely. Low 70s are likely towards the north ends of the Finger Lakes, while areas close to the shore of Lake Ontario will stick near or just below 70 degrees.

Winds slacken after sunset tonight. Temperatures will cool under clear skies, dropping back into the upper 40s and low 50s.

High, thin cirrus clouds will start to filter the sunshine on Friday as winds turn towards the southeast. Some additional, thicker cloud cover may work in late in the day.

Temperatures will be warmer though, with highs in the upper 70s and low 80s.

Stormy Weekend Weather

A meandering storm system will slowly track northeast out of the Ohio Valley towards the Northeastern United States late this week.

By Saturday morning, this low will move into the Lower Great Lakes, causing a surge of moisture to move into the Finger Lakes.

Rain and some thunderstorms are likely on Saturday, though the exact timing of the rain and any possible breaks remain an unknown detail. A period of steady rain seems possible, which could fall during the morning and/or midday hours.

The threat of rain will continue throughout Saturday with another batch of rain expected on Sunday.

There does not seem to be much if any support for severe thunderstorms, but given the position of the low pressure system, the evolution of Saturday’s weather will continue to be monitored.

Total rain amounts this weekend could exceed one-inch for some areas, which would be beneficial.

This storm system will pull out for early next week. A big, prolonged warm-up looks possible for the final days of June and early July.
