Cold Front Approaches

Scattered showers and thunderstorms will pop up again today, mostly during the late afternoon and evening hours.

The trigger for the storms will be a cold front that will move through late tonight.

Much of the day will therefore be hot, dry, and sunny before the thunderstorms develop.

Temperatures will again range from the mid 80s in higher elevations to the low 90s along I-90. Dewpoints will remain in the 60s, making it muggy but not oppressive.

One change from our recent weather will be some noticeable wind. Coming from the south, wind speeds will be over 10 mph with gusts of 25-30 mph.

Showers and storms will be most likely after 4 PM, starting from the west and gradually spreading east well into the evening. There is little support from the mid and upper levels of the atmosphere, so the storms will have a difficult time maintaining themselves or organizing into severe clusters.

As such, only isolated, if any severe weather is expected. This will be most possible early in the event, before the sun sets. Damaging winds are the only threat worth mentioning.

Also, since the storms will have difficulty, there will be areas in our region that see little to no rain once again.

Behind the Front

The front will clear the area before dawn on Wednesday. Winds will turn to the southwest, then west, and finally northwest over the course of the day.

Less humid and slightly cooler air will move in. Highs will mostly be in the upper 70s, though western parts of the Southern Tier may be cooler.

Wednesday will have a mix of sun and clouds. Almost all the region will stay dry, but a stray, isolated shower cannot be completely ruled out.

Thursday will be nearly identical, with highs in the mid and upper 70s with a mix of sun and clouds. Again, rain is highly unlikely, but there will be a very small chance for a brief shower in a few isolated locations.

Rain chances will be even closer to zero on Friday as highs return to the low 80s. Another front will approach on Saturday. The timing of the front is just one of several uncertainties that will impact how the day turns out. At the least, expect some scattered showers and storms.

Some showers may linger into Sunday with several weak disturbances possible next week that could also bring rain showers to the region.
