President Barack Obama has left Westchester after attending back to back Democratic National Committee fundraisers.

He plans to return to Westchester about 6 p.m. Saturday evening for the wedding of Sam Kass, the president's senior policy adviser for nutrition, to MSNBC host Alex Wagner at Blue Hill at Stone Barns in Pocantico Hills. His schedule calls for him to return to Washington again late that night.

Motorists are likely to face road closures as he travels to and from Blue Hill on Saturday evening, similar to those Friday during his trip to New Rochelle and Purchase.

Temporary flight restrictions were issued by the Federal Aviation Administration for Friday and Saturday in anticipation of the president's visit. Regularly scheduled commercial flights are not expected to be significantly impacted, but private carriers and local pilots will have to contend with added obstacles including stops at "gateway" airports for security checks. There are also windows when no aircraft can take off or land.

Here are some alternate routes to avoid the expected temporary freezes:

Hutchinson River Parkway/Merritt Parkway, a good north-south alternate to Interstate 95 assuming the Secret Service doesn't choose to use this instead.

Route 120 (Purchase Street/King Street), Route 120A (King Street): Other alternates to I-684 from North Castle and Greenwich, Conn., south through Purchase, Rye Brook, Port Chester, etc. But they pass Westchester County Airport so could be subject to temporary freezes.

Route 127 (North Streeet/Harrison Avenue): Good route from White Plains through Harrison to Mamaroneck and the Sound Shore.

Mamaroneck Avenue: Another good route from White Plains through Harrison to Mamaroneck and the Sound Shore.

Theodore Fremd Avenue/Halstead Avenue: Good alternate to Boston Post Road (Route 1) in Rye, Harrison and Mamaroneck

Palmer Avenue: Good alternate to Route 1 through Mamaroneck, Larchmont and New Rochelle.
