Last 80 of the Season in Portland Today

October 15, 2015

Portland hit 80 degrees today.  Technically 80.06 since temperatures are reported in Celsius.  That tied the record for today, 80 in October 1991.

There have only been two days in Portland’s history that we’ve hit 80 after this date.  That was the 80 on October 16, 2002 and 81 on October 21, 2003.  Looking ahead, there is no weather pattern that would produce mid 70s or higher, so I think we can confidently say we’re done with 80 degree temperatures for this year.

Easterly gradient was stronger than I expected today; peaking out near 7 millibars.  The peak gust of 63 mph at Vista House was the strongest so far this fall.  Corbett hit 49, and Troutdale a 37 mph gust.  Expect a LOT more of that November through February!

East wind continues tonight so low temperatures only drop to 60-65 in those windy locations.  Down into the 40s and 50s for the rest of us.

Enjoy one more warm day tomorrow because we’ll see more typical clouds and showers at times starting Saturday.  That said, Models are still a bit drier than normal over the next 7 days.  The 10 day GFS total precipitation is less than 1″ over most of the Willamette Valley:

The ECMWF shows under an inch as well.  So a bit wetter, but not a real wet pattern coming up.
