Warm southwest flow

.An intense front will stall over the South Coast mountains today and tonight. The mild and moist southwesterly flow associated with the front has brought freezing levels up and the heavy precipitation will fall as rain except over the high alpine. The front will move inland early Tuesday with lighter precipitation and a cooler airmass in its wake.

On Wednesday a disturbance will push northeastward through Western Washington to lie over the Southern BC Interior in the afternoon. Another frontal system will move northwards offshore on Thursday with an associated warm front brushing the Inner South Coast. This system will slide southwards along the coast on Friday spreading precipitation to the South Coast mountains.
