...Chance for showers and thunderstorms over parts of the Plains
and Upper Great Lakes from Thursday into Saturday...

...Chances for heavy snow over parts of the Northern Rockies/Great
Basin...

The low pressure system that sits over the Northern Plains will
continue to deepen and move northeast through the weekend. With
the cold front extending down into the Southern Plains, moisture
will continue to advect along central CONUS, bringing chances for
showers and thunderstorms to continue for the next few days. Storm
Prediction Center has issued a Marginal Risk (level 1 of 5) for
severe thunderstorms across the central High Plains for tonight
into Friday and across parts of the northern Southern Plains into
Mid-Lower Mississippi Valley for Friday into Saturday. Other
hazards associated with this storm will include a potential for
isolated hail and marginally severe gusty winds within the
stronger cells. By late Saturday, the front will move eastward
into the Mid-South and lower Ohio Valley, allowing for moisture to
pool and instability to increase, bringing a Slight Risk (level 2
of 4) for Excessive Rainfall, with a chance for flash flooding.

Over the Northwest, a surface trough and low pressure system will
gradually move over the Pacific Northwest and Northern Rockies,
bringing chances for occasional heavy rain, especially along the
coast and within valleys, along with high-elevation snow through
the weekend. As the system continues to progress, expect chances
for heavy snow over the North-Central Rockies and Pacific
Northwest. Parts of Wyoming is currently under a Winter Weather
Advisory for heavy snow over higher terrains.

In addition, a weak onshore flow will bringing some moisture over
the western parts of the Gulf coast, promoting scattered showers
and thunderstorms through the weekend. The cold front off the
Florida coast will continue to move southward over the Atlantic
that will bring chances for rain and showers over parts of Florida
through Saturday.
