…Unsettled weather persists throughout much of the West today before the
next strong storm system enters the Pacific Northwest on Saturday…
…Elevated fire weather concerns continue across parts of the Northeast…
…Next round of heavy rain and severe weather potential to develop over
the Southern Plains late Sunday…
The end of the workweek and upcoming weekend will have plenty of potential
weather hazards scattered across the Nation as we reach the midway point
of November. A system crossing the Intermountain West today will continue
to bring areas of moderate snowfall from the central Sierra Nevada to the
Northern Rockies into Saturday. The highest elevations have high chances
(>70%) for at least 4 inches of snowfall and coincide with where Winter
Weather Advisories have been issued. Precipitation is also possible across
the Northern Plains on Saturday as an area of low pressure crosses the
region, with a mix of rain and snow at times. This system will also have
the potential to produce periods of strong winds across parts of the
Montana Front Range on Saturday. As the weekend begins, a strong frontal
boundary and surge of Pacific moisture is set to move inland across the
Pacific Northwest and bring the potential for heavy coastal/lowland
rainfall and snow to the Washington and Oregon Cascades. In fact, Winter
Storm Watches have been hoisted for the Cascades due to the potential for
total snow accumulations of 1 to 2 feet, with locally higher snow amounts
over the highest peaks.
For the East, two separate storm systems brushing coastal regions while a
large area of high pressure builds into the Great Lakes and slides over
the Appalachians by Sunday will drive weather conditions through this
weekend. Gusty winds and locally heavy rain are possible along the Outer
Banks of North Carolina and surrounding Mid-Atlantic coastline today due
to a rapidly deepening, but quickly exiting, low pressure system. Showers
and strong winds will be short-lived as the storm races eastward into the
open Atlantic by tonight, with breezy conditions remaining due to a tight
pressure gradient related to high pressure over the Great Lakes. A
separate storm system swinging into the Canadian Maritimes will produce
showers over parts of Maine, with a light glaze of freezing rain possible
today where temperatures hang just below the freezing mark. In between
these two system will remain a very dry and breezy Northeast, prompting an
additional few days of fire weather concerns. Conditions will remain ripe
for developing wildfires through at least Saturday thanks to a stiff
northwest breeze and low relative humidity, including major I-95 cities
between Philadelphia and Boston.
By late this weekend the next rainmaker for the Southern Plains is
forecast to develop as an organizing low pressure system strengthens over
West Texas Sunday night. This system is then forecast to move
northeastward into Monday morning and spread numerous showers and
thunderstorms between the Texas Panhandle/North Texas to central Oklahoma.
Periods of heavy rain may lead to areas of flash flooding, especially in
urban and poor drainage locations. A few strong thunderstorms may also
have the potential to contain large hail, frequent lightning, and damaging
wind gusts.
