Warmer Air on the Way
A stalled out low pressure system over New England will slowly yield to high pressure building in from the Great Lakes.
The low will once again throw moisture back to the west towards the Finger Lakes. Like the last couple days, though, the majority of the precipitation will stay east of the region.
Low clouds and fog are starting today off in most areas, though a few locations are seeing clear skies. The trend will be for these clouds to burn off this morning, even as the typical daytime heating clouds start to bubble up.
Showers today will primarily stay east of I-81 and thus out of the Finger Lakes. A stray shower further west cannot be totally ruled out though. In the end, most, if not all the Finger Lakes will stay dry today.
Temperatures will be a couple degrees warmer than yesterday with highs mostly in the upper 70s and low 80s. Winds will be from the north at 5-10 mph.
Meanwhile, to our west, a surge of warm air has moved through the Midwest and into Canada, north of the Great Lakes. As the low meanders eastward tonight and tomorrow, that warm air will move southeast toward our region.
Overnight temperatures will be in the low and mid 60s, and sunny skies early Thursday will get temperatures rising quickly.
Highs on Thursday will jump into the mid and upper 80s. A few areas in the northern Finger Lakes may push toward 90 degrees. Dewpoints will mostly stay near or below 60 degrees, so it should not feel too humid out.
Skies will remain quite sunny tomorrow and rain is not expected. There will be a small chance for a shower or storm Thursday night, however. Winds will be from the northwest at 5-10 mph.
Warm Weekend, then Even Hotter
Temperatures will remain warm for the next several days but should not get overly hot yet.
There will be another small chance for scattered showers on Friday. Otherwise, look for sun and clouds. Highs will retreat a couple degrees but should still be in the low to mid 80s.
Saturday should be dry with the typical mix of sun and clouds. Look for highs to gain a couple degrees back, but not be as warm as Thursday. Most areas should be around 85 degrees.
Sunday will be very sunny with a light south wind. That will help temperatures push into the upper 80s and low 90s.
Next week continues to look very hot with daily highs near or above 90 degrees.
How long the heat lasts and how intense it gets are questions that still need to be resolved. It is possible that we could see multiple days with mid 90s for highs.
