Evening Update: More records on March 18:
Wausau WI    62 (61, 1918/1903)
Rochester MN 60 (tied 1945)
Toronto's period of record (1938-2009) is somewhat shorter, but today's high temperature of 18°C was just short of the record 18.9°C. in 1966. Tomorrow's forecast high temperature of 18°C, if it occurs, will easily break the record of 14.2°C set on March 19, 1986.

Several Canadian locations set records on March 17 (Canada basks in record high temperatures). Records were set in Montreal, Ottawa, and Halifax as well as in places as far apart as Manitoba and New Brunswick. So far, March has been the warmest on record in many places following a very warm winter.

Washington Weathercaster Revolving Door Continues to Spin

The churn in the local broadcasting market fed by falling revenues has brought another new face to Washington weathercasting. Following the recent departure of veteran meteorologist Bob Ryan, the 11 pm report on WRC-TV, Channel 4, last night was delivered by Justin Drabick. Drabick's presentation showed a familiarity with local geography undoubtedly acquired during an early career spent on Maryland's Eastern Shore.

After graduation in 2004 from Millersville University, he spent 5 years at WMDT, Channel 47, the ABC affiliate in Salisbury. In December, he moved to WBOC, the Salisbury CBS/Fox affiliate broadcasting on channels 16 and 21. Drabick holds a Certified Broadcast Meteorologist seal from the American Meteorological Society.
