There's a chill in the air today, and it's got nothing to do with the spooky creatures who will be prowling Westport streets later in search of Halloween treats.

While the weather forecast from the National Weather Service says that southwestern Connecticut's daytime temperatures while crest in the high 50s under mostly sunny skies today, things will get decidedly chillier after dusk.

In fact, a freeze warning has been issued for the region from midnight though 10 a.m. Monday.

Today, meanwhile, the NWS wizards predict there will see more of the blustery winds that buffeted the area yesterday, with a northwest wind between 9 and 18 mph, with gusts as high as 28 mph.

Winds will calm a bit after sunset, but temperatures will fall to the low 30s.

On Monday, the day will be sunny, with temperatures climbing from the overnight big chill to a high of about 50 degrees.

The outlook for Tuesday is about the same: sunny with daytime highs of about 50.
