A Wet Evening Eastside

June 18, 2013

Take a look at the rainfall totals as of 10pm…none officially at PDX, .13″ at Hillsboro and then these numbers:


Several heavy showers developed over a few hours, mainly east of I-205.  It did make for this nice view of the west end of the Gorge, a picture taken from Pittock Mansion by Chris Markes!


Other than the heavy rain, not a whole lot of thunderstorm action today with maybe a dozen strikes in NW Oregon and SW Washington.

We’ll see about tomorrow; with plenty of sunbreaks there is no reason we shouldn’t see heavy rain/hail showers develop again.  If we get too much cloud cover, that could squash things a bit.

The cold upper low passes overhead the next two days, then gets out of here Saturday for a much better day.

But uh-oh, next week looks mild and very wet with a strong west-southwest upper flow.  The 12z GFS and ECMWF were both very wet, here’s the ECMWF:


and in map form both the new 00z GFS and 12z ECMWF:



We’ll probably have very warm nights (60) but daytime highs below average during the Monday-Wednesday period next week.

Tuesday Afternoon Action

June 18, 2013

Thunderstorms and heavy showers beginning to pop up over Western Oregon and Washington at 3pm. Just about anyone could see a downpour or thunderstorm between now and sunset! Showers are moving from south to north or actually SSW to NNE.

Nice heavy shower just north of Keizer right now:
