Our air mass changed drastically while you slept (and I was TRYING to sleep, my dog was being a total jerk), going from hot and humid (Portland got to 86 F yesterday with no more than 40 minutes of total sunshine) to seasonable and dry. The cooler air comes on the heels of a frontal boundary that swung through with very little fanfare late yesterday afternoon.
This morning the front is well offshore and we are in prime position to see a beautiful day. Look for mostly sunny skies from start to finish on a dry northwest wind. The wind itself will be a bit strong, with gusts into the 20-25 MPH range during the afternoon. Temperatures will end up in the upper 70s to low 80s, which is at or a bit above normal for this time of year.
Today should be a good beach day as the west wind will fight off the sea breeze circulation and keep temperatures similar to inland locations.
The synoptic setup remains almost exactly the same for the next few days: cold front stalled to our south, high pressure to our north providing a dry west-northwest wind. As a result the forecast is almost identical for Monday-Thursday...mostly sunny with highs in the low 80s. The only chance of precipitation will be an isolated shower or two on Tuesday with a weak upper level disturbance moving through. I'm not sold on this even being an issue however, as the ridge may absorb all the moisture before it gets to us.
It looks like some large scale ridging builds in for later in the work week, allowing the classic "Bermuda High" to setup to our south. That means highs will likely push into the upper 80s by next week with increasing humidity.
All in all this is looking like a GORGEOUS summer week.
By the way, how can a cute, sweet, 11 pound dog be a jerk? Well how about prancing around the bed all night like the mattress was a dancepad for Dance Dance Revolution. Let's just say by 1 AM, this almost happened.
