A strong cold front will push through the northern part of Wyoming early today.  Winds will be strong at times over northern, central and southeast parts of the state.  The coldest part of this air mass will be mainly located across northern and east-central parts of the state through tonight.  Expect scattered to light snow over the northern mountains and plains through this afternoon.  By this afternoon and tonight, scattered snow will be possible over central, east-central (Casper area) and throughout the southeast (Arlington to Cheyenne).   These colder temperatures will make black ice more likely tonight and overnight, especially across northern and eastern parts of the state.  Winds will be strong with the arrival of the front, with gusts up to 50 or 55 mph possible in wind-prone areas.  This cold air boundary will stall on Tuesday, bringing a greater chance for light snow and accumulations to the cowboy state.  Greatest chance for snow on Tuesday will be the northwest mountains, central and southeast regions.
