Weather today will feature an amplifying ridge of high pressure bringing sunny skies and unseasonably warm temperatures with highs in the upper 80’s.

The ridge axis moves east Wednesday with the warm southerly flow on the west side of the ridge axis having even more influence on our weather with sunshine and afternoon high temperatures near record territory into the mid 90’s. Since the ridge has a bit of moisture fluxing through parts of it at times the sky cover does show some variance at times but for the most part but more so on Wednesday as weak disturbance running up the west side of the ridge in the southerly flow.

For Thursday, moisture from a weak weather system will move up into South and Southcentral Washington late in the day bringing mainly clouds to our area with just isolated showers in some locations. Also, the ridge of high pressure over the region will flatten somewhat as a disturbance moves through British Columbia and Alberta Thursday with highs still hot, into the lower 90’s.

The ridge of high pressure amplifies once again Friday bringing sunny skies, light winds and afternoon high temperatures in the lower 90’s.

By the weekend on Saturday, a deep low pressure system will try to break down the ridge and move through the Pacific Northwest. Because of this weather system, we will see a slight increase in high clouds but will remain unseasonably hot with high temperatures Saturday near 90 degrees with upper 80’s expected on Sunday. Temperatures will show several degrees of cooling on Sunday with highs in the mid 80’s, then a pretty good cool down Monday and Tuesday with afternoon highs falling back to within a few degrees of seasonal averages in the lower to mid-80’s.
