Storm Chances Increase

The combination of another hot and muggy afternoon and an incoming disturbance will lead to scattered thunderstorms across the Finger Lakes.

Temperatures will quickly be on the rise this morning and into the afternoon, just like the last several days. It will not take long to reach the 80s while dewpoints range through the low and mid 60s.

Scattered thunderstorms will pop up in the early afternoon. These will be most likely west of Seneca Lake, but all areas have a chance for scattered storms. Still, many areas will end up getting little to no rain as storms skirt around.

The weak nature of the disturbance, the lack of higher dewpoints, and very light winds in the atmosphere all are working against more widespread, robust thunderstorms. Nonetheless, one or two strong wind gusts may be possible.

Outside of any thunderstorms, temperatures will push into the upper 80s and low 90s. Even the typically cooler higher elevations should get above 85 degrees.

Precipitation will dissipate this evening as we lose the daytime heating. Skies will clear, but temperatures will only fall into the mid and upper 60s. A few locations near I-90 may not drop below 70 tonight.

Tuesday will turn out to be similarly hot with highs in many places at or above 90 degrees. Winds will be their strongest in days, coming from the south at around 10 mph.

Most of the day should be sunny and dry, but a cold front will approach late in the day.

This may cause some evening thunderstorms to organize into a broken line. There could be some localized strong storms to watch for. More details on this tomorrow.

Heat Retreats

Behind Tuesday evening’s front, the heat will let up for a few days.

Wednesday will be a partly cloudy day. A couple stray showers may be possible, but most areas should remain dry.

Temperatures on Wednesday will be in the mid and upper 70s with west-northwest winds around 10 mph.

Thursday, too, will be sunny and primarily dry. The only chance for rain will be a few isolated late day showers, mostly over the Southern Tier. High temperatures will be in the upper 70s with a few low 80s also showing up.

Friday looks to be the driest day with no rain at all expected. Temperatures will be a couple degrees on either side of 80.

There is a decent chance for rain by the weekend which could help the rainfall deficits many areas still have. Temperatures will start to rise again, kicking off a hot end of June and start to July.
