ROCHESTER, N.Y. (WHEC) — After a pleasant end to the month of July, August may get off to a stormy start. The News10NBC Weather Team continues a Yellow Alert Day for all of Western New York on Sunday.

Our meteorologists continue to track an area of showers and thunderstorms developing over lower Michigan and parts of Ontario, Canada.

This evening clouds will continue to thicken, but most of the night should remain mainly dry. However, there will be an increasing chance of a shower toward morning.

Tomorrow a surge of humidity will move over Western New York with the passage of a warm front. This will create some marginal instability in the atmosphere with the potential for passing showers and possibly a strong thunderstorm. Although not all the ingredients are there for widespread severe weather any storms could produce small hail and few heavy downpours.

If there are any repetitive storm cells for any location there is the chance of some localized flooding. We expect the temperature will remain within a few degrees of 70 for most of your Sunday. Right now it appears that most of the showers and storms to taper for Sunday evening.

As you head back to work on Monday look for drier air to return to Western New York as humidity levels will lower. This will bring more sunshine and more comfortable weather for the start of the workweek. Once we get a return to this sunshine, it appears we’ll see more consistency to the nice weather as we go through this first week of August.  Expect sunny sunshine, lower humidity and comfortable temperatures right through Wednesday.

In the longer range of our News10NBC First Alert 10 Day Forecast, more traditional mid-summer heat will make a return. Look for temperatures to rise through the 80s for Thursday through Monday with increasing amounts of humidity. There will be a small chance of an isolated thundershower each day.
