Front sweeps humidity out…briefly

Mixed Skies, Low Humidity Friday

Very dry air will briefly movie into the Finger Lakes in the wake of a morning frontal passage.

Clouds associated with the front are over much of the Finger Lakes early Friday morning, but already clearing skies are entering western New York.

Skies will, therefore, be mixed throughout the day, with more clouds in the morning and for areas further south.

One or two rain showers may accompany this front, but most areas will not see rain today.

The air will become very dry behind the front, with dewpoints dropping into the low and mid 50s by this evening.

High temperatures today will reach the mid to perhaps upper 70s. Overnight lows will then drop back into mid and upper 50s.

Front Stalls, Lifts Back North

The front that moves through today will not make it too far south. At the very least, some high, thin clouds may not completely leave the southern parts of the region today and tonight.

These clouds will slowly spread back north Saturday as the front bounces around Pennsylvania.

Dewpoints will return to the 60s on Saturday, with mid and upper 60s for dewpoints across the Southern Tier.

A few afternoon rain showers may even pop up across the Southern Tier and southern ends of the Finger Lakes.

By Sunday, all of the Finger Lakes should see dewpoints back above 65 degrees with a chance for afternoon showers and thunderstorms. Only the far northern reaches of the region, north of I-90, have a decent shot at staying mostly dry Sunday.

Another Wet, Humid Week

As has often been the case since mid-July, the atmosphere will be getting jammed up, resulting in slow-moving weather systems that linger for days.

The frontal boundary that will slowly lift back north this weekend will hang around through the middle of next week. Areas of low pressure will traverse along the front, keeping rain and thunderstorms in the forecast.

Widespread afternoon rain and thunder appear likely on Monday and Tuesday. Wednesday could easily end up wet as well but is still far enough in the future to be uncertain.

A new low pressure system then looks to take aim at the region Thursday and Friday next week with rain, thunder, and possibly some wind as well.

All throughout next week, dewpoints will hover in the muggy, uncomfortable zone of the upper 60s and low 70s, leading to warm overnights. Daytime highs will mostly be in the upper 70s and low 80s, as has mostly been the case lately.
