SUMMARY...THE OVERALL UPPER LEVEL PATTERN TURNED MORE ACTIVE ACROSS
THE NORTHWESTERN U.S. IN APRIL. THIS MEANT MORE PRECIPITATION FOR
MANY LOCATIONS ACROSS CENTRAL AND SOUTHWEST MONTANA COMPARED TO WHAT
FELL IN MARCH. HOWEVER...HAVRE WAS ONE OF THE LOCATIONS THAT
ACTUALLY SAW LESS PRECIPITATION IN APRIL COMPARED TO MARCH.
PRECIPITATION FOR THE MONTH IN HAVRE WAS 0.51 INCHES BELOW NORMAL.
THE AVERAGE TEMPERATURE WAS RIGHT AT AVERAGE FOR THE MONTH.
