Two Records Today In Portland

May 1, 2014

The official high today at PDX was 89 degrees, which busted right through the 85 degree record.  But we also tied the record warm low temperature for the day too.  That was 53, set during the 1998 warm spell.  Here are the other records…

That will be it for the warm/hot temperatures since we have a cold front AND onshore push of cool marine air on tap for Friday.  Low clouds are pushing onto the coastline now and some might even make it into the valley in the morning.  The cold front comes through around 5-8pm.  We could see a shower at that time.  I give it about a 50/50 chance of anyone in the metro area getting a shower before 8pm.

Saturday and beyond?  Looks wet, especially later Saturday and most of Sunday.  Back to the wet spring programming…hope you enjoyed the warm sunshine!

If you are looking for more sun/warm, I don’t see any hint of another warm spell on the ECMWF.  Here is the 12z ensemble chart:

Here is the new 00z GFS ensemble chart, implying we may see ridging and another warm spell about 10 days from now…it’s only 10 days away!

The 00z GEM (Canadian) is similar…we’ll see.

4pm Thursday: 88 in PDX

May 1, 2014

As of 4pm it’s 88 degrees in Portland, that’s at the official observation site at PDX.  We may yet hit 90 today…we’ll see.  Either way we broke the 85 degree record for May 1st.  We also tied a record for a warm low temperature; the low was only 53 degrees this morning.

This morning’s 850mb temp (around 5,000′) over Salem was 19.2 degrees, more like midsummer than May Day!

Astoria, Salem, and McMinnville have tied or broken records for the day as well.
