After almost two weeks of cool weather, a change is definitely in the cards beginning tomorrow. I don’t see any cold upper-level troughs near the Pacific Northwest over the next week. One approaches California later tomorrow through Monday, then another approaches the West Coast later next week. Models seem to be trending towards keeping the lows week and upper-level heights reasonably high for this time of year. As a result I pushed the temperatures in the 7 Day forecast up quite a bit today.
Very impressive easterly flow tomorrow. Check out the 40kts overhead by midday tomorrow. That should surface across all of the Metro area; I have a feeling some will complain about “what happened to the warm Saturday?”.
A few waves of showers move north Saturday night, and again Sunday evening/night. That leaves (supposedly) pretty decent days. Our RPM shows convection popping up over Coast and Cascade Ranges Monday PM as the upper level low gets closer.
Out of time tonight…enjoy the weekend!
