Another  warm front is headed our way bringing some more rain and mild temperatures since the airflow is coming from near Hawaii.  Weak high pressure builds in on Wednesday. The high pressure ridge gets a little stronger Thursday (see blue arrows offshore making an arch over the Pacific Northwest) then allows yet another storm to move in as it weakens late in the week (Friday) bringing back a better chance of rain.
