More of the Same Friday

Friday will be just another summer day in the Finger Lakes, very similar to most days so far in July.

Skies are starting the morning clear and should remain bright and sunny throughout the day. Occasionally a few thin clouds will drift through, but they should have little impact on the amount of sunshine.

Winds have swung back around to the south as high pressure pushes off to our east. Those winds may gust over 20 mph at times today.

With the sunshine and south winds, temperatures will take another jump upwards today with most of the region in the upper 80s or low 90s. The hottest areas will be in and around Rochester, as is commonplace. Parts of the Southern Tier will settle in the mid 80s.

Humidity levels will remain tolerable with dewpoints mostly in the 50s today.

Mostly clear skies tonight will send temperatures back into the low 60s and upper 50s.

Transition to New Pattern

Clouds will be on the increase Saturday morning as low pressure along the East Coast begins to move northward.

At first, these will mostly be thinner clouds which will still allow some sunshine through during the morning. However, by the afternoon, the clouds should become thicker for a more overcast sky.

Rain is still not expected for Saturday, though a faster storm system could start to push a few showers into the southern parts of the region during the very late afternoon or evening hours.

There still remains uncertainty about the path of the low pressure system, but confidence is growing in some beneficial rain for the Finger Lakes late Saturday night and Sunday morning.

Should this rain work into the Finger Lakes, it would likely arrive well after midnight Saturday night and depart well before noon on Sunday. A relatively small area of 1-2 inches of rain will accompany the low and there is about a 50-50 chance that this works into the eastern half of the Finger Lakes, roughly from Keuka Lake eastward.

A couple showers may develop for Sunday afternoon, but generally speaking, the afternoon looks decent if not nice. Temperatures will be held mostly in the 70s, though.

There will be a chance for rain and thunderstorms most days next week. The day-to-day details of what areas are more favored than others will remain uncertain until a day or two beforehand.

Temperatures next week look to remain close to normal, with highs mostly in the upper 70s to low 80s.
