SUMMARY...JANUARY STARTED OUT COLDER THAN NORMAL ACROSS NORTH-CENTRAL
MONTANA...BUT GRADUALLY TRANSITIONED TO AN ABOVE NORMAL WEATHER
PATTERN TOWARDS THE MIDDLE OF THE MONTH. THAT WARMER THAN NORMAL
PATTERN REMAINED IN PLACE THROUGH THE END OF THE MONTH.
OVERALL...JANUARY SHOWED MORE VARIABILITY IN TEMPERATURES AT THE GREAT
FALLS AIRPORT WITH TEMPS REACHING AS HIGH AS THE UPPER 50S LATE IN THE
MONTH AND DROPPING AS LOW AS -7 EARLY IN THE MONTH. DESPITE SLIGHTLY
ABOVE NORMAL PRECIP...THE GREAT FALLS AREA ENDED UP 2.2 INCHES BELOW
NORMAL ON SNOWFALL. ONE INTERESTING NOTE REGARDING THE SNOW IS THAT THE
SNOW DIDN`T MELT OFF AS QUICKLY AS NORMAL. OFFICIALLY...THERE WAS A
STREAK OF 40 CONSECUTIVE DAYS WITH AN INCH OR MORE OF SNOW ON THE GROUND.
THE STREAK WHICH STARTED IN DECEMBER...ENDED JAN 22. IT WAS THE 9TH
LONGEST STREAK SINCE RECORDS BEGAN AND THE LONGEST STREAK SINCE 1985.
