SUMMARY...HAVRE WAS 3.0 DEGREES WARMER THAN AVERAGE AND
RECORDED THE 11TH HIGHEST MONTHLY TOTAL PRECIPITATION DURING
JANUARY. THESE AVERAGES OBSCURE LARGE DEPARTURES FROM NORMAL THAT
OCCURRED THROUGHOUT THE MONTH. A LARGE SCALE RIDGE OVER THE PACIFIC
NORTHWEST ESTABLISHED A NORTHWEST FLOW OVER MONTANA THROUGH THE
FIRST THIRD OF THE MONTH. THIS PATTERN MAINTAINED COLD AND SNOWY
CONDITIONS THROUGH THE PERIOD. 0.24 INCHES PRECIPITATION ON THE 5TH
SET A NEW DAILY RECORD. SNOW DEPTH IN HAVRE REACHED UP TO 9 INCHES.
THE RIDGE BROKE DOWN THROUGH THE MIDDLE OF JANUARY WITH WARMER THAN
AVERAGE TEMPERATURES. THE UPPER LEVEL RIDGE STRENGTHENED AGAIN OVER
THE INTERIOR WEST...PUSHING TEMPERATURES WELL ABOVE AVERAGE. HIGH
TEMPERATURES OF 54 DEGREES ON THE 26TH AND 60 DEGREES ON THE 27TH
SET NEW DAILY RECORDS.
