ADDED A SLIGHT CHANCE OF THUNDERSTORMS FRIDAY AFTERNOON IN CENTRAL
MOUNTAINS AND SOUTHERN HIGHLANDS WITH WEAK INSTABILITY PRESENT.
SYSTEM SATURDAY DROPS FURTHER SOUTH AND MODELS TRENDING TO DRY IT
OUT SOME BUT KEPT IN ISOLATED TO SCATTERED POPS THROUGH THE PERIOD
WITH FRIDAY LIKELY WETTEST DAY. EXPECT COLDER CONDITIONS THROUGH
THE PERIOD GETTING COLDER EACH DAY WITH A RETURN TO MORE SEASONAL
NORMAL FOR LATE FEBRUARY. MAJOR IMPACTS NOT EXPECTED BUT SOME
MOUNTAIN ROADS COULD OCCASIONALLY SEE SOME SNOW COVER INTO

HIGHS IN THE MID OR UPPER 30S. EXPECT A BRIEF DRY PERIOD ON MONDAY
