Heading into the Oven

A serious Heat Event continues to capture our attention; in the mean time, enjoy the pleasant summer temperatures before Nature’s Oven gets left open. Here’s the breakdown.

• Aug 2,3 weekend:  Warm temps, primarily in the upper 80s, with slightly cooler temps around the Sound.  East side a bit warmer.  More thunderstorms possible to the east, esp late Sunday. 
• Next week, Aug 4-8:  Generally, ‘cool’ for summer, with temps in the 70s under an onshore flow.  Patrons up in the Puget Sound north could get a few showers late Thu the 7th; cloudiness elsewhere in western WA; limited clouds around Oregon.  Enjoy the coolness, as the big heat-up begins soon.
• Weekend of Aug 9,10:  This period will mark the transition into what could be multiple days of triple-digit temps in many west side locations.  Saturday should be in the 90s region wide, excluding the usual ‘bit cooler’ Puget Sound.  Sunday will begin the climb — Medford triple-digit; Willamette Valley & SW WA high 90s.
• Week of Aug 11-15:  MAJOR HEAT WAVE.  Temps this DAILY this week are modeled to climb into the 103-105 range by Wed the 13th (108 Medford).  Overnight lows will be uncomfortable for folks w/o air conditioning (65-73).  Monday of this week will likely be the coolest day - if you want to call it that - at 99.  Again, around the Puget Sound & BC it will likely not be so hot.  (This heat dome is not like the historic Canada-based high pressure ridge of late June 2021.)
• Weekend of Aug 16,17:  Yes, the HEAT WAVE CONTINUES into this weekend.  Triple-digits probable in many west side locations.  

—> The pattern driving the heat wave is NOT modeled to change much when the week of Aug 18 arrives, as an onshore flow has yet to be indicated.  

Too early to confirm every detail of the upcoming Heat Event, but we have seen this pattern on the charts for quite a few days now.  Hence, the forewarning.  Patrons that will be traveling away from home —> make plans this coming week to be sure pets & plants will receive adequate care.  Farm animals will need extra water.  All of us MUST pay attention to neighbors that do not have air conditioning, as this type of heat wave is life-threatening.
