Weather Underground Forecast for Wednesday,March 11,2015
Wet
weather is expected on both the East and West Coasts on Wednesday. A low
pressure system that brought heavy rainfall to the Eastern Valleys will
combine with a low pressure system moving through eastern Canada as it
advances northeastward. As these systems move eastward and offshore, a
cold front trailing behind this system will allow for moderate to heavy
rainfall to persist from southern New England through the Gulf states.
Rainfall totals will range from 0.5 to 1.0 inches for most areas, with
some isolated areas seeing over an inch of rain. Flood advisories will
remain in effect for the Eastern Valleys due to the rain and snow melt
creating high water levels for the rivers of the region.
Meanwhile out West, a strong low pressure system spinning in the North Pacific Ocean will continue advancing northeastward toward British Columbia. This system will create a cold front that stretches down the West Coast and moves onshore throughout the day. Expect rain showers to develop from British Columbia through central California, with heaviest precipitation expected over the Washington Cascades. Snow levels will remain above the Cascade Pass level. As this front slowly advances eastward, expect the Sierras to see some snow. Snowfall levels may range from 6,000 to 7,000 feet Wednesday night, but significant snowfall accumulation is not expected due to limited moisture associated with this system.
