Favorable Trend

Wow, it’s already the last week of the month and, for some, the final week of summer vacation.  HOT conditions will slowly cool as this week progresses.  We may have caught a “wx break” during the upcoming US holiday weekend; read on for details.  

Wrap around moisture from a Low centered over the CA-OR-NV border is training cloudiness over portions of the PNW this morning.  The are some thunderstorms associated with this pattern, so stay alert (east Eugene/Springfield getting hit as this is written).  Similar to the past few days, clouds may clear away somewhat by the afternoon, allowing the heat to build rapidly.  For all regions, temps in the upper 80s to 90s are possible for many locations today & Tue.  Somewhat cooler on Wed and another drop in temps by Thu/Fri.  Think low 80s.

Labor Day Holiday:  a favorable trend on the wx charts suggests the expected wet pattern may not develop - or be delayed enough for Patrons to sneak in a few pleasant days for outdoor activities.  Right now, some precip is possible, but quite spotty.  (Often model outlooks do shift back to earlier solutions, so keep that in mind.)  Overall, temperatures will moderate into ‘comfortable’ for most locations.  Higher humidity will help with fire fighting.

Next week - Sep 2-5 is trending rather pleasant in the temp department, as the ‘heat dome’ will shift over ID, with limited threat for precip.  Again, higher humidity will help with fire fighting.

The weekend of Sep 6,7 is looking WET for southern BC, as cold air to the north clashes with warm air over northern WA.  This is a new feature, so expect some modification going forward.  Warmer over the rest of the PNW (mid-to-upper 80s), as compared to the 'short week' after Labor Day.

HEAT may return again (not unusual for this time of year) in the Sep 9-10 period.  

Overall, we just don’t see any significant rainfall during the next 2 weeks, unless one gets caught under a thunderstorm.
