...Another quick moving spring storm to bring chilly and windy
weather to Northern Johnson County and the Bighorn Mountains on
Monday...

A reinforcing cold front will continue to bring unseasonably cool
weather to Northern Johnson County and the adjacent Bighorn
Mountains on Monday. As the front pushes through, north winds will
increase to 30 to 40 mph with some gusts to 50 mph. The wind will
combine with high temperatures in the 50s at the lower elevations
of Northern Johnson County along with 30s and 40s in the Bighorn
Mountains resulting in unseasonably chilly conditions, including
wind chills as low as the upper teens in the mountains.

In addition, a driving rain will develop as this front pushes
through the area with snow expected across the Big Horn Mountains
above 7000 feet Monday where up to 3 inches of snowfall could
accumulate.

For those planning on venturing outdoors on Monday, especially in
the Big Horn Mountains, please prepare for unseasonably chilly
weather along with the potential for slick and snow covered roads,
especially on Powder River and Granite Passes. Stay tuned for
further statements regarding this weather event.
