A Late August Heat Wave ??

 

Several dog days of summer on the way.  We can always expect a variation in the weather outlook, so read on for the latest adjustment.

 

This will be a warm-to-hot week around the great PNW.  Wed & Thu remain the hottest days in our forecast this week, although clouds may tap down temps a bit in OR on Thu because of possible mid-level moisture could set off thunderstorms late Wed into Thu.  Keep alert for this, as it is a new twist for the week.  Friday continues to look very pleasant, as Nature will turn on the onshore marine ‘air conditioner’.  

 

The weekend ahead should be pleasant; it will trend a few degrees warmer than Fri.  Puget Sound Patrons could see some drizzle and cloudiness late Sunday, as a weak Low pushes onshore.  Iffy.

 

For Mon - Fri, Aug 22-26, the wx models are now trending much warmer than our last report.  It will start out pleasant on 26th, with each day ticking up the afternoon highs.  What looked to be a mild temperature day to start the Oregon State Fair on the 26th, is now charting to be the beginning of yet another HOT streak for the PNW.  The onshore flow stops completely and the 'oven door’ of the desert SW gets left open - setting up another round of triple-digits in areas across the PNW during the final days of August 2022.

 

East side thunderstorms possible late Sunday the 28 into Monday the 29th.  HEAT is now charting well into the last day of August.  We present this as a possibility, as earlier computer runs suggested milder conditions.  As we have said many times, those older projections frequently end up the most accurate, so it may not get that hot.   Let’s hope so.  

 

In the meantime, enjoy the 'dog days’ of August this week while anticipating the broad cool down next week.
