Showers continue as front wobbles to and fro

Remaining Unsettled

More rain is in the forecast for the next 24-36 hours as a stalled out frontal boundary takes several passes through the region.

As of 7 AM this morning, the front was situated from Wayne County back to the southwest into Cattaraugus County. East of the front, periods of rain, some heavy, are falling with temperatures in the mid 50s. West of the front, rain is more scattered with temperatures ranging through the 40s.

Most of the heavy rain is departing the region, but showers will continue to be widespread through the morning. A gradual decrease in the number and intensity of the showers is expected this afternoon, though it looks doubtful that the entire region will ever completely be dry today.

During the times it is not raining, it will remain cloudy, with little to no sunshine working through the clouds today.

The front should progress to the east and clear the area by the early afternoon. Temperatures will be in the upper 40s and low 50s across the Finger Lakes once this happens, while areas just to the south and east rise well into the 60s.

Temperatures this evening will not drop much as clouds remain thick and showers increase in coverage once again. After midnight, the front will lift back north through the region and south winds will increase.

By dawn Wednesday, temperatures will range through the mid and upper 50s, while the Rochester area could push to 60 degrees. A few showers or rumbles of thunder will exist early on north of I-90, but the trend will be for dry conditions and sunnier skies through Wednesday morning.

With south winds gusting over 25 mph and the sunshine, temperatures will shoot into the low and mid 70s Wednesday afternoon.

But then the front will take another pass.

A line of showers and possibly thunderstorms will develop and drop southeast through the region during the mid to late afternoon hours. Severe weather is not expected, but temperatures will fall back into the 60s behind the line.

A Small Break

High pressure will build in Wednesday night, resulting in partly cloudy skies and temperatures dipping back into the mid and upper 40s.

That high will press east Thursday, gradually turning our light winds to the southeast. Skies will remain partly cloudy and precipitation should not fall.

High temperatures on Thursday should range through the low and mid 60s.

The wind will increase Thursday night and become more southerly, keeping overnight temperatures in the upper half of the 50s.

Partly cloudy skies and dry conditions are expected, which should result in another mild day. Look for highs to range from the upper 60s to the mid 70s.

A new front will move into the area Saturday morning. Temperatures will quickly drop 10 to 15 degrees following the frontal passage, and most of Saturday will be spent in the upper 40s and low 50s.

Rain showers will accompany the front, but rainfall amounts look modest at this time.

If skies clear Saturday night, Sunday morning could end up frosty. If the clouds hold, though, lows will likely stay near or above 40 degrees.

Saturday’s front may also stick around for a while, which could lead to more rain early next week.

A colder weather pattern than we have seen yet this fall should set up behind that weather complex for the final days of October and continuing into early November.
