...Heavy snow possible over the Cascades, Sierras, Intermountain West...
...Well above normal temperatures for the Central and Northern Plains...
...Heavy rain and flash flooding possible across South Texas this
weekend...
A cold front that moved onshore across the Pacific Northwest yesterday
will continue to move slowly inland today, pushing across northern
California and the Intermountain West, and then into the Rockies by
Sunday. Onshore flow behind the front will direct moisture into the
Coastal range, Cascades, and northern and central Sierras today. The slow
motion of the front will lead to a prolonged period of moderate to heavy
snow in these areas, as well as inland across the intermountain west and
into the Rockies by Sunday. The coastal regions from Oregon to California
can expect rain and thunderstorms during this time. Winter Weather
Advisories and Winter Storm Warnings are in effect for portions of the
Intermountain West, Pacific Northwest, and California for heavy snow.
While the cold front is pushing across the Pacific Northwest, west to
southwesterly flow over the Continental Divide will lead to a warming and
drying trend across much of the Central and Northern Plains. Temperatures
will soar to as much as 20 to 30 degrees above normal, making it feel much
more like spring. Strong high pressure will build over the eastern U.S.,
leading to below normal temperatures, however those will moderate toward
the end of the period as the warmth pushes east.
On the western edge of this high pressure, strong return flow will be
present, with a deep layer of warm and moist air filtering into Texas from
the Gulf of Mexico. A mid level shortwave will interact with this unstable
and water loaded airmass, sparking showers and thunderstorms across
southern and eastern Texas today. These will spread eastward into the
Lower Mississippi Valley Sunday, and then northward up the Mississippi
Valley and into the Upper Great Lakes during the day Monday. The Weather
Prediction Center continues to carry a slight risk for excessive rainfall
and flash flooding across southern Texas for today. Please refer to our
website for more information concerning the heavy rain threat. The
rainfall and cloud cover will also lead to below normal temperatures
across Texas today as well.
