DAYS 1-5 (AUGUST 25-29)
High pressure will be in control of the weather throughout this period, which starts out comfortably warm and turns out hot and more humid. We’ll continue to see some smoke in the high altitudes from wildfires in the Canadian Rockies and western US at times through the weekend. Previously I had mentioned some old boundaries getting close to the region and although this is still true, I am currently thinking the air will be too warm aloft to support any shower and thunderstorm activity through this forecast period. Forecast details…
TODAY: Areas of fog early, otherwise sunshine filtered at times by high altitude smoke. Highs 77-85, coolest coast. Wind S up to 10 MPH.
TONIGHT: Mostly clear except some patchy ground fog forming late at night and also some areas of smoke continuing, filtering moonlight. Lows 61-68. Wind light SW.
SUNDAY: Sunshine again filtered at times by some high altitude smoke. Highs 78-86, coolest South Coast. Wind SW up to 10 MPH.
SUNDAY NIGHT: Partly cloudy. More humid. Lows 63-70. Wind SW up to 10 MPH.
MONDAY: Mostly sunny and hazy. Humid. Highs 84-93. Wind W 5-15 MPH.
TUESDAY & WEDNESDAY: Hazy sunshine & a few clouds. Very humid. Lows from the upper 60s to middle 70s. Highs from the middle to upper 80s South Coast, 90s elsewhere.
DAYS 6-10 (AUGUST 30-SEPTEMBER 3)
Expecting a cold front to come through dry early August 30 which will be not as hot, still quite warm, but becoming less humid, then high pressure moving to the north of the region will turn wind more onshore by August 31 which will be a fair and significantly cooler day. Labor Day Weekend September 1-3 currently looks like it will not be without the threat of a few showers but should be mostly rain-free with a gradual return to warmer and more humid weather.
DAYS 11-15 (SEPTEMBER 4-8)
This period looks variable in temperature as a boundary may be nearby, possibly starting out very warm to hot and humid, then featuring somewhat of a cool down as high pressure to the south gives way to high pressure nosing out of Canada, with the boundary in between eventually being pushed southward. Hard to know this far in advance when threats of unsettled weather will be.
