Glorious weekend, then drier-than-normal spring

Mar 29, 2013

First, the good news: enjoy this weekend, which is shaping up to be wonderfully mild and full of sunshine with highs in the 60s across Western Washington.

After that, be ready for plenty of twists and turns. April is the month of frequent weather changes, says Cliff Mass, professor of atmospheric sciences at the University of Washington.

The two hallmarks of April:

  •         Cumulus clouds, which are big, puffy and dramatic
  •         Short but intense rainstorms, with an occasional thunderstorm

But it seems we’ve lucked out this year. Yes, we’ve heard this spring will be cooler than usual, but Mass says it also looks drier than normal, at least for much of April. 

“The high pressure in the east Pacific will be stronger than normal … and that tends to make us cooler than normal, but it also makes us drier than normal,” says Mass.

“So it looks like this spring may not be quite as bad as the last two, which were both cooler and wetter than normal.”
