"Tis a privilege to live in Colorado" - F Bonfils
Here's the prediction straight from NOAA:
A STRONG SPRING STORM WILL MOVE INTO SOUTHERN UTAH TUESDAY AFTERNOON...AND THEN TRACK ACROSS COLORADO TUESDAY NIGHT AND WEDNESDAY MORNING. PRECIPITATION IS EXPECTED TO DEVELOP IN THE MOUNTAINS TUESDAY...AND THEN SPREAD ACROSS THE PLAINS TUESDAY AFTERNOON AND NIGHT. HEAVY SNOWFALL IS POSSIBLE ESPECIALLY OVER THE FRONT RANGE MOUNTAINS AND FOOTHILLS. IN ADDITION...TEMPERATURES MAY BE COLD ENOUGH TO BRING SNOW INTO THE URBAN CORRIDOR AND PORTIONS OF THE PLAINS AS WELL...ESPECIALLY LATE TUESDAY NIGHT INTO WEDNESDAY. THERE IS STILL CONSIDERABLE UNCERTAINTY WITH THE TRACK OF THE STORM...AND ANY VARIATION TO THIS TRACK WILL HAVE EXTREMELY LARGE IMPLICATIONS ON TEMPERATURES AND THE AMOUNT OF SNOWFALL AT ANY GIVEN LOCATION.
Here's a great site with helpful information for protecting your plants tomorrow night!
