Advisories: NONE AT THIS TIME.

An upper level high pressure ridge (“Arch” shape) has moved over the Pacific Northwest giving us the Summer heat and sunshine that so many of us have been waiting for. An upper level trough of low pressure is rolling in behind the ridge early in the week and with a weak frontal system (shown offshore) will bring us more clouds and cooler temperatures. Will it bring just clouds or will we get showers too? So far it looks like just the clouds. More disturbances will approach us by the end of the week.
