DETERIORATION IN TRAVEL CONDITIONS AFTER PASSAGE OF THIS COLD

TO 8 INCHES IN THE FOOTHILLS...3 TO 6 INCHES IN THE MOUNTAINS...
OVER THE PALMER DIVIDE AND NEAR THE FOOTHILLS IN BOULDER...

ADJACENT PLAINS ON THURSDAY WITH MUCH COLDER TEMPERATURES
THAT WILL CONTINUE INTO FRIDAY. HIGH TEMPERATURES ON THE PLAINS
MAY ONLY BE IN THE UPPER TEENS AND LOWER 20S THURSDAY AND FRIDAY
WITH OVERNIGHT LOWS IN THE SINGLE DIGITS. ADDITIONAL SNOW
ACCUMULATIONS ON THURSDAY OVER THE EASTERN PLAINS WILL BE LIGHT
WITH HIGHER ACCUMULATIONS CLOSER TO THE FOOTHILLS. HIGHER
MOUNTAINS AND FOOTHILLS COULD SEE ANYWHERE FROM 6 TO 8 INCHES BY
THURSDAY EVENING WITH LOCALLY HIGHER AMOUNTS OVER THE HIGHER
MOUNTAIN PASSES.

LIGHT SNOW WILL CONTINUE IN THE MOUNTAINS THROUGH THE WEEKEND WITH
A FEW INCHES OF ADDITIONAL ACCUMULATION EACH DAY. CONTINUED COLD
TEMPERATURES AND A SLIGHT CHANCE OF SNOW WILL BE THE RULE ACROSS
THE NORTHEAST COLORADO PLAINS AS WELL.
