…Cooling trend spreads from West to East this week….
…Fire Weather concerns for portions of southern California and Texas
through mid-week…
Systems moving by the northern Intermountain West bring the promise of
snowy periods in and near western Montana, Idaho, and Wyoming through
Wednesday. The first of those systems moves out into the Midwest, Ohio
Valley, and Northeast, bringing rain and thunderstorms near and to the
cyclone’s east, with thunderstorms most likely across portions of the
Eastern Shore and New Jersey on the afternoon and early evening of New
Year’s Eve. As the cyclone moves through the Northeast on Wednesday, both
Lake Effect and Lake Enhanced snows will spread through the Great Lakes
and into the northern and central Appalachians. Between 6-12 inches of
snow are forecast to accumulate downwind of the Lower Great Lakes by
Thursday morning. Some mixed precipitation is expected across central New
England.
A system arriving from the Great Plains will promote snow showers for the
broader Great Lakes region on Tuesday. A cooling trend started in the
West expands east through the rest of the country over the next couple of
days. Building high pressure across the Great Basin is expected to
increase winds across southern California over the next couple of days,
promoting an increased fire weather risk which could become critical
through mid-week. Wind advisories, a red flag warning, and a fire weather
watch have all been posted for the area as well for parts of south-central
Texas through Tuesday.
