WEAK SURFACE HIGH PRESSURE CENTER AND RIDGE ALOFT BRINGING DRY WEATHER WITH LIGHT WINDS TODAY. SATELLITE CHANNELS SHOW CLOSED UPPER LOW OVER SE WA MOVING VERY SLOWLY SE. THIS HAS SPREAD RAIN TO THE EAST SLOPE OF THE ROCKIES. THIS WILL START TO SPREAD INTO OUR SW LATE TONIGHT. MODELS ARE IN PRETTY GOOD AGREEMENT WITH THIS SYSTEM MOVING SE THRU ID...THEN TURNING NE AND MOVING THRU NE MT AS A CLOSED UPPER LOW THU/THU NIGHT. THIS SYSTEM NOT NEARLY AS STRONG AS THE PREVIOUS SYSTEM...HOWEVER SUCH A CLOSED SYSTEM THIS TIME OF YEAR THAT IS MOVING RATHER SLOWLY...IS CERTAIN TO PROVIDE SIGNIFICANT RAINFALL. MODELS HAVE IMPRESSIVE STRONG LIFT AND PRECIP WATER AS HIGH AS 1.0 INCH IN OUR AREA. MODELS SHOWING POTENTIAL OF HALF AN INCH OR SO STORM TOTAL QPF LOOK MOST REASONABLE. WITH THE TIME OF YEAR AND WET PATTERN OF LATE...LEANING TOWARD THE WETTER MODEL SOLUTIONS...WHICH ARE AROUND IN INCH IN OUR S. SHOULD PROVIDE A GOOD 18 HOURS OR SO OF STEADY RAIN MOST AREAS. NOT EXPECTING AS MUCH CONVECTION SUCH AS PRODUCED BY THE PREVIOUS SYSTEM AS INDICATED BY FORECAST SOUNDINGS AND WEAKER NATURE OF THIS SYSTEM...SO GOING WITH STEADY RAIN CHARACTER AND NO THUNDERSTORMS. WARMEST HIGHS IN OUR E-NE THU WHERE RAIN STARTS LAST. SURFACE LOW CENTER IS OVER WY AND MORE OF AN INVERTED TROUGH THRU NE MT...ENOUGH THAT WE MAY APPROACH LAKE WIND ADVISORY CRITERIA THU AFTERNOON. THIS SYSTEM WILL GRADUALLY MOVE OUT OF THE AREA WITH RAIN ENDING BY FRI MORN. DRYING IS MODEST THOUGH FROM THE W...WITH THE AIRMASS MORE UNSTABLE FOR LINGERING ISOLATED SHOWERS. .LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY... THE LONG TERM FORECAST PERIOD BEGINS WITH A VERY BRIEF CALM PERIOD AS CONTINUED UNSETTLED WEATHER TAKES AIM ON NORTHEAST MONTANA. GENERAL UPPER LEVEL TROUGHINESS WILL BE PRESENT OVER THE NORTHERN ROCKIES AND THE NORTHERN HIGH PLAINS THROUGHOUT THE EXTENDED FORECAST PERIOD. BEST CHANCES FOR WELL ORGANIZED SHOWERS AND THUNDERSTORMS WILL BE ON SATURDAY...LINGERING INTO SUNDAY. MODEL AGREEMENT IS QUITE GOOD THROUGHOUT THE EXTENDED PERIOD...WHICH WOULD TEND TO INCREASE CONFIDENCE IN THAT FORECAST. COOLER THE AVERAGE TEMPERATURES AND UNSETTLED WEATHER IS THE GENERAL FORECAST THEME. BMICKELSON PREVIOUS LONG TERM DISCUSSION...FRIDAY NIGHT AND BEYOND...THE LONG TERM FORECAST PERIOD CONTINUES TO LOOK UNSETTLED. A SERIES OF SEVERAL SHORTWAVES WILL CROSS THE REGION THROUGH THE EXTENDED PERIOD...AND THE TIMING OF THESE SHORTWAVES WILL BE DIFFICULT TO PIN DOWN AS MODEL SOLUTIONS DO NOT AGREE ON EXACT TIMING AS OF YET. THEY DO AGREE ON GENERAL TIME FRAMES SO WE WILL HAVE TO WORK WITH THIS FOR NOW. THE FIRST SHORTWAVE WILL CROSS THE REGION STARTING SATURDAY FOLLOWED BY ANOTHER ONE ON SUNDAY. BOTH OF THESE WILL PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS. RAIN WILL PROBABLY BE HEAVY AT TIMES AS MODELS SOUNDING SHOW PRECIPITABLE WATERS BETWEEN 0.80 - 1.10 INCHES BETWEEN SATURDAY AFTERNOON AND MONDAY MORNING. THE NEXT TWO SHORTWAVES WILL BRING ACCUMULATING PRECIPITATION TUESDAY AND WEDNESDAY NIGHT ALTHOUGH MODELS ARE NOT IN GOOD AGREEMENT WITH THESE TWO FEATURE YET. MODELS ARE TRYING TO BRING MORE OF A ZONAL FLOW AFTER MONDAY WHICH MEAN TIMING OF THESE WAVES WILL BE DIFFICULT FOR THE MODELS TO PIN DOWN. AS FOR TEMPERATURES IN THE EXTENDED WE WILL REMAIN BELOW OUR AVERAGE FOR THIS TIME OF THE YEAR. RSMITH && .AVIATION... VFR WITH INCREASING CLOUDS TONIGHT.

NEARLY EVERY CREEK AND STREAM NORTH OF THE MISSOURI RIVER WAS AFFECTED AS WATER PILED UP. THIS IN TURN HAS CAUSED THE CREEKS AND STREAM TO CONTINUE RUNNING VERY HIGH WITH MANY FLOWING OUT OF THEIR BANKS FLOODING LOW LYING AREAS. THE MILK RIVER BEGAN RISING RAPIDLY LAST NIGHT...GLASGOW SURPASSED THE PREVIOUS RECORD STAGE FROM 1952 EARLY THIS AFTERNOON AND THE RIVER HAS NOT QUITE CRESTED AS OF THURSDAY AFTERNOON. AREAS DOWNSTREAM HAVE ALSO NOT YET CRESTED. THE MISSOURI RIVER BELOW FORT PECK DAM WILL SEE A SUBSTANTIAL RISE IN WATER LEVELS THROUGHOUT THE WEEK DUE TO PLANNED WATER RELEASES FROM THE FORT PECK RESERVOIR.
