Stormy Interruption

Friday August 16

After a weekend highlighted with thunderstorms, what will the rest of August be like outdoors?  You know the drill:  ☕️ Mug Up.

The pleasant temperatures experienced this past week will continue, but first the pattern will be interrupted, as the PNW is likely to experience the potential for rather intense thunderstorms & heavy showers this weekend.  It will remain warm, with elevated humidity.  Starting tomorrow afternoon, moisture moving north - from an unusually deep Low for summertime positioned along the southern OR coast - will train into western OR, SW WA and, subsequently, western WA & southern BC.  The stormy pattern will continue through Sat evening, with spotty action on Sunday, as well.  Given the position of the Low, conditions will improve south-to-north by late Sunday. 

⚠️ NOTICE: the atmosphere will be super-saturated with moisture, so any storm cell that moves over your particular location has the potential for VERY HEAVY RAIN, powerful wind gusts, and, yes, lightning.  Sudden standing water issues and localized flooding in low spots will be probable; drivers be aware!  All PNW forecasters are ‘on this’ — Ignore the cautions at your own risk!

As noted above, next week promises another series of pleasant afternoons, with periodic morning marine clouds that burn off later in the morning.  Wednesday could present additional moisture over areas north of Portland up to Olympia.  We will touch on this in our next update on Monday.

The weekend of Aug 24,25 looks pleasant.

While still quite a few days out on the forecast models, starting Tue the 27th, we continue to see another HEAT UP as the month of August comes to an end.  Temps should pop into the 90s in many western OR & WA locations; tad warmer east side, per usual.  This pattern, should it verify, is likely to hold into the first few days of September.  

Meanwhile, stay weather-alert this weekend.
