Trending a Bit Cooler

'Baking the west' - that’s the impact of our current heat wave.  Temps will top out at or above 100 in many western OR & SW WA locations, and east of the Cascades today & Tue, before finally cooling down into the 80s to low 90s Wed & Thu (even high 70s in NW WA), as an onshore flow aids in heat relief.  By Fri the 12th, the onshore flow weakens, resulting in temperatures popping up again - probably into the 90s (bit cooler over the Puget Sound).  Overall, a warm-to-hot weekend coming, although not quite as toasty as the current ‘bake’.

The week of July 15 - 19 continues to trend much more pleasant, with a notable onshore flow component; temps should remain seasonal (80s primarily inland; tad cooler for NW WA, southern BC.  Morning marine cloud deck, at times.

By the July 20,21 weekend, a weak Low pressure trough will slowly work north from Brookings area, setting off possible thunderstorms over the Cascades; with Sunday likely to be STORMY over eastern WA & along the eastern slopes of the WA Cascades.  Hikers & Campers be alert, should this verify.

Pleasant summer temps are charting for the last week of July.  That could change, so keep your morn’n Mug handy as we continue to revise the long-range outlook here every Mon & Fri.
