URGENT - WINTER WEATHER MESSAGE
National Weather Service Denver CO
1147 AM MDT Tue Apr 9 2019

...STRONG WINTER STORM EXPECTED TO MOVE IN WEDNESDAY...

.Very warm temperatures are expected today, ahead of a developing
upper level storm system moving over the Great Basin. Drastic 
changes in the weather are expected to occur on Wednesday as a 
strong cold front will race across northeast Colorado which will
bring much colder temperatures, strong north winds and heavy 
snow. Areas of heavy snowfall across the Front Range to the far 
eastern plains and strong winds will result in poor visibility and
difficult driving conditions. Temperatures plummeting will result
in icy roads. Residents of northeast Colorado should begin making
preparations for this developing storm to avoid being caught by 
harsh winter conditions.
