Valid 12Z Mon Feb 20 2017 - 12Z Wed Feb 22 2017
...Slight risk of severe thunderstorms over parts of the Southern Plains
continuing into Monday morning...
...Heavy snow possible for the Sierras, Sawtooth and Wind River/Absaroka
Ranges...
...Heavy rain likely for portions of Northern/Central California--
possible for the Pacific Northwest coast...
...Heavy rain possible for portions Western/Central Gulf Coast...
Much of the West Coast will remain in an active wet pattern through
mid-week as multiple Pacific fronts move through the region. A nearly
continuous plume of moisture will be directed toward portions of central
and northern California through Tuesday-- resulting in heavy rainfall
along the coast and valleys; with mountain snow. Snow and lower elevation
rain will also develop over parts of the Northern Intermountain region
through Tuesday as the the front pushes out into the High Plains.
Additionally, northern stream upper-level energy associated with the deep
upper-level trough over the Rockies will move to the Great Lakes by
Tuesday morning. The energy will aid in producing rain over parts of the
Northern Plains/Upper Mississippi Valley today and spreading into the
Great Lakes/Western Ohio valley by Tuesday morning.
A strong line of thunderstorms developed Sunday evening along and ahead of
the eastward-moving cold front through the Southern/Central Plains. The
showers and thunderstorms are expected to move east into the
Lower/Mid-Mississippi valley by this afternoon, extending northward into
the Tennessee valley. Warm Gulf air streaming northward along the front
will help maintain higher precipitation for the Gulf states. Heavy
rainfall may develop and increase the threat for flash flooding. Please
refer to WPC excessive rainfall outlooks for additional information on the
risk for heavy rain and flash flooding.
