GUSTS UP TO 60 MPH WILL BE POSSIBLE AFTER MIDNIGHT...ESPECIALLY IN WIND PRONE AREAS OF NORTHERN JEFFERSON AND BOULDER COUNTIES. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY GUSTY DOWNSLOPE WINDS WILL OCCUR IN THE FOOTHILLS FRIDAY AND FRIDAY NIGHT WITH SPEEDS OF 50 TO 60 MPH POSSIBLE. A DISTURBANCE IN STRONGER WESTERLY FLOW ALOFT WILL PRODUCE LIGHT SNOW FRIDAY EVENING IN THE NORTHERN MOUNTAINS THEN INCREASE QUICKLY AFTER MIDNIGHT AND INTO SATURDAY EVENING. SNOW AMOUNTS OVER THE PARK AND GORE RANGES NEAR RABBIT EARS PASS MAY REACH 10 TO 20 INCHES...WITH LOWER AMOUNTS EAST OVER THE MOUNTAINS NEAR ROCKY MOUNTAIN NATIONAL PARK. MOUNTAINS FURTHER SOUTH NEAR THE I70 CORRIDOR WILL RECEIVE MUCH LESS...PERHAPS 3 TO 8 INCHES. AREAS OF BLOWING SNOW ARE EXPECTED LATE FRIDAY NIGHT INTO SATURDAY MORNING OVER THE NORTHERN MOUNTAINS. A COLD FRONT WILL PUSH SOUTH ACROSS THE PLAINS BY SATURDAY EVENING TO BRING AREAS OF SNOW OR A MIX OF RAIN AND SNOW SATURDAY NIGHT. THE COMBINATION OF THE FRONT COUPLED WITH A STRONG JET OVERHEAD COULD PRODUCE BANDED SNOWFALL OVER THE NORTHEAST PLAINS SATURDAY NIGHT. A FEW LOCATIONS COULD PICK UP A QUICK INCH OR TWO UNDER ONE OF THESE BANDS. SUNDAY WILL BE COLDER WITH A CONTINUED SNOW OVER THE CENTRAL MOUNTAINS...THEN THE CHANCE OF LIGHT SNOW WILL BUILD NORTH OVER THE PLAINS DURING THE EVENING.

IF THE STORM SYSTEM MOVES INTO SOUTHEASTERN COLORADO LATE SUNDAY NIGHT THROUGH MONDAY EVENING IT COULD BRING SIGNIFICANT SNOWFALL AND STRONG EASTERLY WINDS TO THE FRONT RANGE MOUNTAINS...FOOTHILLS AND NORTHEAST PLAINS. IF IT TRACKS FURTHER TO THE SOUTH...THEN THE FOCUS FOR THE HEAVIER SNOW WILL SHIFT TO THE SOUTH AS WELL. LATELY THERE HAS BEEN A SHIFT OF MODELS TOWARD THE FURTHER NORTH SOLUTION...SO SIGNIFICANT SNOWFALL WILL REMAIN A POSSIBILITY. AREAS OF LIGHT SNOW AND GUSTY NORTH WINDS MAY CONTINUE INTO TUESDAY MORNING. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT. ENTREKIN/KRIEDERMAN
