Weather forecast: Scattered lake effect rain showers develop as cooler air fills in overnight


Detailed forecast for Rochester, the Lakeshore & Finger Lakes

6 PM UPDATE: The leading edge of our cold front is passing to our east this afternoon providing a break from widespread rain and storms. On the backside of this system much colder air is filling in which will continue to provide clouds and showers that are more scattered in nature. We’re not completely out of the woods yet in terms of rain, but the steady, persistent band is no longer with us. The threat for severe weather is near zero at this time, and the instability left behind is barely enough to see any lightning or thunder for now.

DISCUSSION: After a soggy and stormy start to the weekend with rainfall totals up to 2+ inches across parts of the region, the backside of a cold front will bring in much cooler air, clouds and scattered lake effect rain showers through Sunday and Monday. Temperatures drop into the upper 40s and low 50s by Sunday morning offering a much different flavor to our mornings than we have over the past week.

On and off lake rain showers last throughout much of Sunday with gusty winds up to 30 mph at times. There will be dry time mixed in, but bursts of heavy rain and thunder is possible in these showers; even a waterspout isn’t out of the question given all the lake induced instability.

Temperatures will offer a notably cooler feel but will be much more seasonable for mid October with highs in the 50s both Sunday and Monday. This will warrant the Fall season attire; pants, jackets and sweater. The 60s make a return by the middle of the week with more sunshine. Our next round of rain looks to hold off until Thursday of next week. More details to come.

Enjoy your weekend!
