THE FIRST HALF OF MAY 2013 WAS DRY ACROSS MOST OF NORTH CENTRAL AND
SOUTHWEST MONTANA. TOWARDS THE LATTER HALF OF THE MONTH A TROUGH OF
LOW PRESSURE SET UP OVER THE PACIFIC NORTHWEST BRINGING A MOIST AND
UNSTABLE SOUTHWESTERLY FLOW ACROSS THE AREA. THIS RESULTED IN
SCATTERED SHOWERS AND THUNDERSTORMS ALONG WITH PERIODS OF HEAVIER
WIDESPREAD RAIN...ESPECIALLY OVER THE ROCKY MOUNTAIN FRONT. AT THE
END OF THE MONTH A STRONG AND SLOW MOVING STORM SYSTEM TRACKED
THROUGH THE REGION BRINGING WIDESPREAD RAIN TO CENTRAL AND NORTH
CENTRAL MONTANA. RECORD RAINFALL WAS RECORDED WITH THIS SYSTEM IN
HAVRE ON THE 30TH AND 31ST. PRECIPITATION FOR THE MONTH OF MAY WAS
WELL ABOVE AVERAGE...WITH A TOTAL OF 4.60 INCHES. OVERALL
TEMPERATURES WERE NEAR AVERAGE FOR MAY.
