Windy, warm and wacky weather is giving way to a chilly but uneventful week.
Sunday's early-afternoon high temperature of 60 degrees made Buffalo the warmest spot in the Northeast. But winds gusting as high as 50 to 55 mph blew in colder air, and temperatures plunged 21 degrees in four hours.
The wind is now gone -- and so is the warmth.
Temperatures should be slightly lower than normal for the next few days, producing a "quiet, cold week," said Steve McLaughlin, a National Weather Service meteorologist.
After a low near 20 degrees tonight, temperatures are forecast to reach the upper 20s or low 30s on Tuesday. Highs in low to mid-20s are expected Wednesday and Thursday, with a chance of light snow on Thursday.
Wind advisories were posted for the region for most of Sunday.
Winds gusted to more than 45 mph at the National Weather Service office at Buffalo Niagara International Airport in Cheektowaga in the late morning and again in the early evening. Dunkirk saw peak gusts of more than 50 mph.
n Other areas reported gusts of 50 to 55 mph. The area avoided widespread damage, as the winds were apparently "just below the damage threshold," McLaughlin said.
The wind was blamed for the collapse of a warehouse under construction in Niagara Falls, Ont., at about 11 a.m., causing extensive damage.
Niagara Regional Police said the building at Kraft Canada, 5651 Lewis Ave., was in the framing phase. A steel girder fell onto nearby Lorne Avenue.
The wind also brought down tree limbs and caused scattered power outages. It blacked out a few traffic signals on Niagara Falls Boulevard and another in Batavia.
