Portland OR, historically slow start to spring

Remember back when this alarmist news about snow in the Pacific Northwest
was reported by Time Magazine in March 2006:

Lately the early arrival of spring and the unusually blistering
summers have caused the snowpack to melt too early, so that by the
time it’s needed, it’s largely gone.

Fast forward five years to 2011 and we have this news reported by NWS Portland:

…HISTORICALLY SLOW START TO SPRING CONTINUES FOR THE REGION…
THE COLD…DAMP AND DREARY WEATHER THE PAST FEW WEEKS HAS LED MANY
IN THE PACIFIC NORTHWEST TO WONDER IF SPRING WEATHER WILL EVER
ARRIVE THIS YEAR. BY SEVERAL MEASURES…2011 IS GOING INTO THE BOOKS
AS ONE OF THE SLOWEST STARTS TO SPRING IN RECORDED HISTORY FOR
SOUTHWEST WASHINGTON AND NORTHWEST OREGON.
HERE WE ARE ALMOST A MONTH INTO ASTRONOMICAL SPRING…AND HIGH
TEMPERATURES IN THE 60S HAVE BEEN RARE OR NON-EXISTENT ACROSS THE
DISTRICT. PORTLAND AIRPORT AND MCMINNVILLE SET NEW RECORDS ON
MARCH 31 BY HAVING THE LATEST FIRST 60-DEGREE DAY IN A CALENDAR
YEAR. ASTORIA AIRPORT HAS YET TO REACH 60 DEGREES IN 2011.
THE FAILURE OF TRUE SPRING WEATHER TO START ON TIME THIS YEAR CAN BE
MEASURED IN MANY WAYS…
