GENERAL OUTLOOK

WARMER AND DRIER THAN NORMAL JULY ACROSS MOST AREAS

A series of weak low pressure systems moving across British

Columbia brought showers and cool temperatures to British Columbia

and Washington early in the month. Much drier conditions dominated

through the rest of the month as the main storm track moved north

of the region. A strong area of high pressure brought record

high temperatures to many locations July 9 - 13.
