President Barack Obama and First Lady Michelle Obama will be arriving at Westchester Airport this afternoon but they won't be staying in one spot for long. Once they've landed, the President is expected to head to a Democratic fundraiser in New Rochelle, and then he'll be off to a fundraiser BBQ at the home of financial backer, Robert Wolf, in Purchase. Late this afternoon, Obama will head to Rhode Island for a side trip, and then will return to Westchester by the evening. Tomorrow, the Obama's will attend the wedding of Senior Policy Adviser for Nutrition, Sam Kass at Blue Hill at Stone Barns

Of course, expect at least a few air and trffic delays over the next 48 hours.

• The New York State Thruway Authority says there will be brief road closures from 1:30 to 5 p.m. on Interstate 684 between Purchase and Armonk, Interstate 287 between White Plains and Port Chester and I-95 between Pelham and Connecticut.

Temporary flight restrictions have been issued by the Federal Aviation Administration for today and Saturday. While regularly scheduled commercial flights won't be significantly impacted, private carriers and local pilots will have contend with added obstacles including stops at "gateway" airports for security checks. There are also windows when no aircraft can take off or land.
