Much of today will be calm and mild, making it a pleasant last day of summer. However, an approaching cold front will send summer on a stormy note tonight.

Sunshine will be abundant this morning, mixing with a few thin wisps of cirrus and possibly a few fair weather clouds. A gentle but steady southerly wind will team up with the sun to warm temperatures quickly.

In the afternoon, the sky will be a mixture of sunshine and growing fair weather clouds. The southerly wind will veer slightly to the southwest as it picks up momentum. Mid to late afternoon wind speeds will be near 10 mph with gusts to 20 mph.

Temperatures will reach between 75 and 80 degrees, with the highest elevations in the north being the coolest, and urban areas and the southern part of the county being the hottest.

The timing of thunderstorms is a bit up in the air. The earliest they could arrive was late afternoon. At the latest, the rain will stop until nightfall.

When thunderstorms arrive, provided it is no closer to midnight than sunset, there could be strong to severe thunderstorms. Frequent lightning and destructive winds will be the main threat. However, most areas will likely see no damage.

Behind the thunderstorms, showers will spend the night with a cold front. Temperatures will stay in the low 60s until the front clears, but then drop into the mid to even low 50s at sunrise.

Here is an overview of the weather forecast for the next few days:

Thursday: Morning sun and clouds. Afternoon showers Morning lows in the mid 50s. Afternoon highs in the 60s.
