Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 358 AM EST Sun Feb 08 2015 Valid 12Z Sun Feb 08 2015 - 12Z Tue Feb 10 2015 ...Wet weather will continue across northern California and the Pacific Northwest... ...Snow will begin to pile up over portions of New England... ...Temperatures are expected to remain well above average in the Rockies and Southern Plains... After a brief lull in shower activity across the West...a strong cold front approaching the coast will bring another surge of moisture and round of heavy rain into northern California and the Pacific Northwest Sunday night. Precipitation will spread east over the northern Rockies as the cold front progresses inland on Monday. Initially high snow levels will begin to drop with the frontal passage...leading to locally heavy snowfall accumulations along the Cascades...Rockies...and Sierra Nevada Range. Once the front pushes out into the northern Plains Monday night...a wintry mix of precipitation will be possible over portions of eastern Montana and the Dakotas. An axis of snow will continue to set up to the north of a frontal boundary stretched from the Great Lakes to the Northeast coast. A deepening surface low along the boundary and increased flow off the Atlantic will help enhance snowfall rates over portions of New England Sunday and Monday...and the long duration of the event should lead to impressive snowfall accumulations. A narrow area of sleet...freezing rain...and rain will be possible to the south of the snow axis. As the deepening surface low sinks southeastward Monday night into Tuesday...scattered shower activity will be possible ahead of the trailing cold front pushing towards the Southeast coast. Elsewhere across the Nation...temperatures will remain well above normal beneath an upper ridge sliding in over the Rockies and southern Plains early this week.
