..More heavy mountain snow in the Sierra Nevada and drenching
rain with gusty winds for California today...
..Strong to severe thunderstorms with heavy rain across the
southern Plains as well as the Upper Midwest to the Great Lakes
through today...
..Another round of severe thunderstorms possible across the Upper
Midwest to the Great Lakes Monday night into Tuesday morning...
An energetic low pressure system is currently moving onshore into
California early this morning. The Sierra Nevada will possibly
receive up to 2 additional feet of heavy snow today while the
lower elevations will be drenched by up to an inch of rain with
gusty winds from this system. Meanwhile, mountain snow and
lower-elevation rain will quickly spread further inland across the
Great Basin and up into the interior Pacific Northwest through
Monday. From Monday night into Tuesday morning, the precipitation
across the Pacific Northwest and the northern Rockies will begin
to taper off. However, as the upper-level low pushes farther
inland across the Desert Southwest toward the Four Corners,
scattered showers and high-elevation snows will spread from west
to east across these areas Monday night into Tuesday morning.
Across the mid-section of the country, another low pressure system
is forecast to track across the northern Plains before merging
with a cold front dipping into the Great Lakes on Monday. Strong
to severe thunderstorms along with heavy downpours are expected to
move across the Upper Midwest to the Great Lakes for much of today
with the passage of a warm front. Some of the rain with embedded
thunderstorms will move across northern New England tonight and
into Monday before tapering off Monday night. Also on Monday, the
severe weather threat remains in place through central Texas while
a new severe weather threat emerges across the upper Midwest later
that day. This is in response to a low pressure wave developing
along a frontal boundary. The severe weather and heavy rain
threats will then head east across the Upper Midwest to the Great
Lakes Monday night into Tuesday morning.
The warm air across the mid-section of the country will expand
eastward into the eastern U.S. during the next couple of days,
with potential for record breaking highs over parts of the
Mid-Atlantic, Southeast, Mississippi Valley, and Ohio/Tennessee
Valley on Tuesday. Meanwhile, a cooling trend will gradually work
its way across the western U.S. with ongoing unsettled weather
associated with the low pressure system.
