52 here could be a pretty chilly start to fall. Definitely will be in the upper 40s by sunrise.

The EURO run tonight is also quite different. Mild to warm through roughly Monday. A new interesting wrinkle for Tuesday-Tuesday night with a cut-off low over northern California resulting in S-SE flow aloft and convective moisture for Oregon, possible t-storms. Long range moisture arrives from the west as the pacific jet takes aim at us with rain increasing. Not bad!

Really good sign when the dps are dropping along with the temps this evening.  A number of 30s are looking likely around the area.

If the warm pattern that has been looking possible falls through you know we've turned the corner.  It's like a switch was flipped in mid August.

Going to assume this was the hottest JJA on record...shitty. If September doesn't bring much rain then we will have brown grass or just dirt by December and January's 60F+ shitfests.

Good news is our coldest temps should be here in a little less than 2 months tho so getting down to around 23F on one night will be the highlight of the regular season for down here.

The run to run change on the EPS at day 10 is pretty extraordinary.  Something has definitely changed.

Looks like I had 68/48 IMBY for the last day of August.  The last half of the month was impressively cool.

The EPS control shows another unseasonably cold trough just like the current one just after day 10.  I'm getting super intrigued now.

Look! We're twins, figured I'd do one for SEA as well! A solidly cool second half of the month at SEA and consistently tamed. Maximum average was 67.5F... impressive numbers the last couple days.

PDX had something like an 89/64 average the first fifteen days of August, followed by a 77/57 the 16th-31st. Pretty decent turnaround.
