Alongside reporters, unusually chilly weather will greet Hollywood celebrities at the red carpet ceremonies of Sunday’s 83rd annual Academy Awards.

Temperatures will only manage to rise to the mid-50s today in Los Angeles, including at the host site of the Oscars, the Kodak Theatre in Hollywood. The red carpet ceremony kicks off at 2 p.m. PST.

Such a high temperature is more than 10 degrees below normal, making this one of the coldest red carpet ceremonies in Oscar history. In fact, the forecast high of 56 is just two degrees above the record for lowest high temperature for the date.

Overnight tonight, the mercury will dip well into the 40s downtown, challenging the record low of 39 from 1962.

Fortunately, a dry forecast has allowed workers to remove one of the rain tents covering the red carpet. Forecasts earlier last week noted the chance for rain during the ceremony.

The chilly weather continues to flow in across California and the rest of the Southwest in the wake of a winter storm which brought rain and rare low-elevation snow to the region.

AccuWeather.com Expert Senior Meteorologist and Western Expert Ken Clark even observed some snowflakes near Burbank, Calif. on Saturday.

Fortunately, a return to more seasonable weather is expected across Southern California by late week as the thermometer rebounds to near 70.
