Severe thunderstorms, damaging winds possible today; cooler Sunday

We're coming to the end of the line on sultry summer weather, and the door's about to smack us on the way out.

The passage of a warm front through the Buffalo Niagara region earlier Saturday will help to ripen the air to create the possibility for severe weather in advance of a cold front which will sweep through the area later in the day.

Temperatures will get into the low to mid 80s with dewpoints in the low 70s making it feel awfully sticky.

Increasing afternoon southwest winds, in some cases gusting above 30 mph, will tend to reduce the feeling of any stagnant mugginess. Some chances for some showers or thunderstorms exist.

Late afternoon into evening, will be the prime time to be aware of the skies.

Starting about 5 p.m. chances for rain increase and become more likely by mid to late evening.

Winds associated with the advancing cold front will pick up again, especially after about 9 p.m. and could be gusting near 40 mph around 11 p.m., forecasts show.

Rain will be widespread throughout the area, including very heavy downpours in some thunderstorms.

Because of high wind shear expected, forecasters cautioned that it's possible storms could strengthen and become severe.

In fact, the Storm Prediction Center of the National Weather Service shows a slight possibility for a tornado along Lake Ontario's southern shoreline up through the North Country. It's the only area in the nation where a tornado is possible today.

That cold front will also sweep away the spate of unseasonably warm and muggy conditions that have persisted since the start of the month.

Extended forecasts suggest it could also spell the end of mid-summerlike weather.

Sunday's high will only be in the low 70s.

The temperature picks up again Monday and Tuesday with temperatures expected in the upper 70s to low 80s under high pressure before much cooler air comes into the region by mid-week.

Wednesday's forecast high is just 65 degrees.

If it holds, it will be the first day the thermometer didn't get to at least 70 degrees in Buffalo since June 13.

Daytime highs Thursday are also forecast in the upper 60s.

It could be the first back-to-back days of below normal weather in more than two months, the weather service stated.

The early forecast for Thursday night's home opener for the Buffalo Bills looks to be a chilly one too.

Mostly clear conditions are forecast. The temperature is expected to be about 60 degrees at kickoff with light northeast winds.
