WINTER STORM WATCH

URGENT – WINTER WEATHER MESSAGE

National Weather Service Rapid City SD

1147 AM MDT Wed Mar 14 2018

.A moisture laden storm system will move from the Rockies into

the central Plains Thursday into Friday. The storm will draw

colder air into it, which would allow precipitation to change to

snow over parts of northeastern Wyoming and western South Dakota.

Relatively warm air above the ground may support freezing rain or

sleet, mainly east of the Black Hills, with enough accumulation

to cause notable icing.

Uncertainty still exists with the exact track of the storm as

well as it’s temperature profile. Stay tuned to later forecasts

for updates.

…WINTER STORM WATCH REMAINS IN EFFECT FROM LATE THURSDAY NIGHT

THROUGH FRIDAY AFTERNOON…

* WHAT…Heavy snow possible. Total snow accumulations of 4 to 6

inches, with localized amounts up to 8 inches, are possible.

* WHERE…Portions of northeast and the Black Hills Wyoming and

northwestern, southwestern and the Black Hills South Dakota.

* WHEN…From late Thursday night through Friday afternoon.

* ADDITIONAL DETAILS…Plan on difficult travel conditions,

including during the morning commute on Friday. Significant

A Winter Storm Watch means heavy snow, strong winds, freezing

precipitation, and cold temperatures are possible. Monitor NOAA

weather radio, local radio or television, or the Internet for
