A Wet Weekend, Warmer & Drier Ahead

9pm Sunday…

Yesterday was exciting with lots of lightning in the valley during the afternoon hours.  Then outflow wind from those storms plus a switch back to onshore flow gave us gusty evening wind in the metro area.  Overnight some hefty showers moved through too.  Here are the weekend rain totals:

Rain Totals Metro Area


I expect a little more rain west of the Cascades this week, but I think we’ll stay below a 1.50″ total going into the Memorial Day Weekend.  Maybe only an inch here in Portland.  This 10 day cool/wet period only has a few days left and we’ve been cheated a bit by lows going farther south into California than initially anticipated.  This is similar to a wintertime El Nino pattern.  Look how dry Seattle has been and then check out San Francisco and Santa Barbara!  May total so far…

Rain So Far This Month Or and Wa Earth Scene

Now those California numbers don’t look huge, but compared to normal they are “way out of whack” one could say.  Check how the numbers above compare to typical May rain through the 19th

Rain Totals West Coast Percent

So Sacramento has seen 6 times the average so far this month, that includes a record .83″ today with hail showers around too.

The general weather pattern is still on track this week; a chance for showers tomorrow and Tuesday, then warming/drying the 2nd half of the week.  Not TOTALLY dry, but west of the Cascades I don’t see many showers after Tuesday.  Models are hinting at thunderstorms developing over the Cascades Wednesday/Thursday; we’ll see if they head straight south along the mountains or come out over the valleys.  Regardless, temps will be warming the 2nd half of the week.  More on that tomorrow…

    This weather sucks. Sunny all day until it’s time to get off work. Then just enough rain to ruin hanging outside. Lame.

    just pull in set up camp [glamming] in St. Augustine Fl. 94 deg and NO EAST WIND, 30 years of it you people can have it. No more snow shovel for us, no more getting hurt in that freezing rain and NO more getting kick out of our home because some kid set out gorge on fire. That kid is so dumb didn’t even know the ripple effect.

    Thunderstorms this afternoon?

    And I guess you were right, Mark. Flow aloft is in fact coming down out of the North. That’s a weird one…

    We are running greater than 4 degrees warmer than normal in May. Quite an anomaly.

    Fairbanks and Phoenix are both 68 deg right now!

    Ended the day with 0.60″ yesterday, after the 0.19″ from Saturday. 0.79″ in less than 24 hours, that was a decent bit of rain overnight, and then a couple quick heavy showers later around dinner time.

    About the potential for thunderstorms Wednesday/Thursday, I think you meant to say “…we’ll see if they head straight NORTH along the mountains or come out over the valleys.”
