HOT then Damp

The weather charts are showing a range of conditions over the next couple of weeks, with the timing of precipitation unfortunate.  ☕️ Mug time.

• ⚠️This weekend, Aug 23,24:  HOT.  Temps in the mid-to-upper 90s - even a few 100+ degree readings - in many locations around the PNW; NW WA & BC will be a bit cooler, however upper 90s remains probable away from the Sound shoreline.  Regionally, a DRY AIR MASS, so fire danger will be elevated.  Overnight low temps in the 60s, even 70s in a few locations.  Fan Up.
• ⚠️Next week, Aug 25-29:  HOT through at least Wed.  Some mid-level moisture may ‘ride north’ from the desert SW, setting off thunderstorms over the OR & eastern basins.  There are indications for an onshore flow to begin overnight Wed Aug 27, which would tap down the heat 7-10 degrees as the week ends.  It could be WET on Thu the 28th, esp north of Portland, as the first of a series of rain fields arrive.
• Labor Day Weekend, Aug 30-Sep 1:  While not totally resolved, models continue to suggest a cooler & DAMP holiday weekend, with systems moving onshore from the west.  We mentioned this last time and the solutions remain ‘wet’.  Not a total wash-out, but if verified, just about everywhere around the PNW will get cloudiness and moderate amounts of precipitation.  Labor Day itself may be the driest day of the holiday period.
• Post Labor Day week, Sep 2-5:  The short work & back-to-school week will likely start out cool and gradually warm throughout the 4 days.  
• Weekend of Sep 6,7: HOT again.  

🌀 Topical Tropical: Well, the latest tropical charts have dropped any hurricane threat for the US mainland through at least Sep 8.  FERNAND, if it develops, will spin out over the Atlantic as a fish storm.  Other tropical storm development is now being hindered by dry Saharan Dust.  Hopefully, this means we caught a break for now.  It is the peak of hurricane season, so we can expect future development.
