October starts off a bit stormy

Showers and Storms in the Finger Lakes

A series of frontal boundaries will touch off showers and thunderstorms across the Finger Lakes region on Monday and Tuesday.

Monday is starting off with one of these fronts draped from west to east across the region. Rain showers are located to the north of the front, mostly to the north of the Finger Lakes.

The front should sag south throughout the day as a new batch of rain moves in from the Upper Great Lakes. These showers will move into the Finger Lakes during the late morning and should persist on and off through the afternoon.

Areas further north should see more rain than those to the south, but no one will see excessive amounts today.

The front will have a sharp temperature gradient, with highs reaching near 70 degrees near the NY/PA State Line while most of the northern Finger Lakes only sees upper 50s for highs.

This evening, the front will lift north and the warmer air will push in. By Tuesday morning, temperatures will have risen into the upper 50s and low 60s as far north as Dansville, Penn Yan, Ithaca, and Cortland.

Warm air will continue to push north after sunrise and should make it all the way to the shore of Lake Ontario by late Tuesday afternoon. Temperatures will therefore reach highs in the upper 60s to perhaps 70 degrees across the entire region Tuesday.

However, an approaching cold front will trigger widespread rain with a few embedded thundery downpours. Showers will be likely during the morning with the more widespread rain arriving for the afternoon. The rain should taper back to showers for the afternoon.

There will be a very small chance for a brief gusty wind or some minor small-scale flooding.

Mild Weather Persists

Sunnier weather should build in for Wednesday behind the front. Watch for some areas of morning fog.

Lows on Wednesday will start in the mid and upper 50s. Afternoon highs will reach the mid and upper 60s, which is still just a touch warmer than normal.

South winds will build Wednesday night ahead of another front. Temperatures should shoot into the upper 70s on Thursday ahead of the front with some showers possible late in the day.

Friday will be a bit closer to normal with a mix of sun and clouds and highs in the low 60s.

However, beyond that, an extended period of very warm weather looks possible. High temperatures in the 70s and even low 80s look to be commonplace through the weekend and into next week.

Of course, the day to day variables of rain and cloud cover will likely reduce some temperatures, but that remains unclear at this point. Overall though, the pattern looks warm through much of the first ten days of October.
