KEY MESSAGES

- Dry weather with above normal temps continue through next week.

- Breezy conditions return Sunday/Sunday night.

DISCUSSION

A broad upper trough over the Gulf of Alaska will allow storm systems to crash into British Columbia over the next several days with drier/weaker systems emerging lee of the Rockies.

This pattern brings mild and dry conditions with an increase in winds with any dry fronts that pass through. Winds this afternoon are expected to become calm tonight but begin increase from the SE Sunday then turn to the W late in the day. Highest winds look to be near the Canadian border so no Wind products will be issued with this package.

Ridging builds back into the Pacific Northwest Tuesday night and expands throughout the week. This should keep conditions dry through the end of the work week but ensembles amplify this ridge heavily into Friday. Afterward confidence goes to low as ensemble groups disagree on how to break the ridge down.

Did blend Winds Sunday afternoon and night with the NBM90. The remainder of the forecast was left alone. TFJ
