For the forecast, Sunny conditions with inverted temperatures into next week. High pressure will be with us for a while, with a Northerly flow aloft for today.  Freezing level will gradually rise tonight with warm air moving into the zone for Thursday. FL will likely peak on Friday at just under 3000 meters. Should come back down to around 1500 meters by Monday. There is some hope that the low to the South will gradually move North early next week with some precipitation. Models are in disagreement so confidence is low.  Get out the sun screen!!

    Strong upper level ridge has formed over the PACNW.

    Low to the South might bring a change by Tuesday???

    High pressure moves around a bit, but is here until next week.

    Low to the South might move into the area later next week. Warm offshore flow.
