AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
926 AM MDT THU MAY 27 2004

.SHORT TERM...FOR NORTHEAST MONTANA TODAY
WEAK UPPER RIDGE TRYING TO BUILD INTO THE AREA FROM THE
WEST...HOWEVER IN THE INTERIM WE HAVE A MODERATELY UNSTABLE
ATMOSPHERE WITH MOISTURE OPLENTY. NOT SEEING MUCH IN THE WAY OF A
TRIGGERING MECHANISM...ALTHO IT WOULD ONLY TAKE A LITTLE SHOT OF
ENERGY TO SPUR SHOWERS AND A FEW THUNDERSTORMS. STAGNANT
QUASI-STATIONARY FRONT LYING ACROSS THE NORTHEAST CORNER OF THE
CWA...AND THIS SEEMS TO BE THE MOST LIKELY PLACE FOR CONVECTION THIS
AFTERNOON. THERE ARE ALSO A FEW DWINDLING SHOWERS THERE FROM LAST
NIGHT. WILL KEEP THE HIGHER CHANCE POPS IN THE NORTHEAST AND TAPER
DOWN TO SLIGHT CHANCE IN THE SOUTHWEST FOR THIS AFTERNOON. SATELLITE
IMAGERY INDICATING LOTS OF SUN FOR AT LEAST THE LATE MORNING HOURS
SO TEMPERATURES SHOULD BUMP UP NICELY. WILL DROP THE FLOOD WATCH NOW
AS THE MILK RIVER HAS BEHAVED ITSELF ABOUT AS EXPECTED.

.LONG TERM... SATURDAY NIGHT THROUGH THURSDAY....
CURRENT FORECAST LOOKS ON TRACK DESPITE MODEL INCONSISTENCIES ON HOW
TO HANDLE THE NEXT SYSTEM.  LATEST MODEL RUNS FAVOR A MORE NORTHERLY
AND SLIGHTLY SLOWER SOLUTION...RESULTING IN A WETTER AND COOLER
WEEKEND FOR THE AREA. POSSIBLE MODERATE RAINFALL OVER THE AREA THIS
WEEKEND COULD POTENTIALLY RESULT IN FLOODING IN MANY AREA STREAMS
AND RIVERS.  THIS IS CURRENTLY THE 14TH WETTEST MAY ON RECORD IN
GLASGOW...AND HAVE DECENT SHOT OF CRACKING THE TOP TEN THIS UPCOMING
WEEKEND.  SURFACE TROUGH MOVES INTO THE AREA ON SUNDAY AND REMAINS
IN THE AREA THROUGH EARLY NEXT WEEK.  LOW BEGINS TO MOVE OUT OF THE
AREA MONDAY INTO TUESDAY... BUT TIMING IS STILL UNCLEAR.  FORECAST
WILL POSSIBLY NEED TO BE TWEAKED AROUND THIS TIME FRAME ONCE TIMING
ISSUES BECOME RESOLVED. WARMER AIR MOVES IN BEHIND THIS LOW AS A
RIDGE ATTEMPTS TO BUILD INTO THE AREA DURING MID TO LATE PORTIONS OF
NEXT WEEK. BT

&&

.HYDRO...MORE RAIN OVER THE NEXT SEVERAL DAYS WILL CREATE MORE
RUNOFF. ONE AND THREE HOUR FLASH FLOOD GUIDANCE IS ONLY AROUND AN
INCH IN THE MILK RIVER DRAINAGE BASINS SO ANY HEAVY RAIN THAT OCCURS
WILL LIKELY RESULT IN MORE FLOODING.

&&

.GGW WATCHES/WARNINGS/ADVISORIES...NONE.
