Monday July 6
A turn in the weather, for the good of all, will take place
later this week. The record-breaking (for many locations)
extended heat wave will come to an end as cooler, the marine
air conditioning returns.
The normal marine air that helps keep the PNW pleasant during
summer months literally was blocked by a ridge of high pressure.
By Thu/Fri, the ridge will yield and allow for cooler air in the form
of an 'onshore flow' to push inland to cool the entire region down
to seasonal temperatures.
By the weekend, temperatures will drop enough to generate quite
a conversation about how cool it is in comparison to the heat. Plants
& people will be grateful. The good news is that the cooler, more
normal PNW pattern for July will hold on through at least July 18
or 19. West side, the moisture will mainly manifest as scattered
mid-level clouds, but a shower may pop up, esp from Eugene south.
General temps will range from the mid 70s to lower 80s in many
locations, cooler along the coast. Eastern basins likely to be in the
mid-80 to low 90s. Normal for July.
