Area forecast discussion, Jul 1, 7:14 PM MST, 41 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 914 PM CDT WED JUL 1 2015 .UPDATE... ISSUED AT 905 PM CDT WED JUL 1 2015 SEVERAL STRONG THUNDERSTORMS MOVING ALONG THE MONTANA/NORTH DAKOTA BORDER FROM NEAR SIDNEY SOUTH TO BAKER. ADDED SMALL HAIL AND GUSTY WINDS TO GRIDS THIS EVENING. OTHERWISE SEVERAL CELLS DEVELOPING NORTH OF BISMARCK ALONG AN OLD OUTFLOW BOUNDARY. NO LIGHTNING YET BUT EXPECT SOME IN THE NEAR FUTURE. WILL REFINE POPS FOR THE EVENING KEEPING THE NORTH CENTRAL LOW AND THE HIGHEST POPS ALONG THE CANADIAN BORDER AND ALONG I94 BETWEEN BISMARCK AND JAMESTOWN SOUTH. UPDATE ISSUED AT 623 PM CDT WED JUL 1 2015 CONVECTION SEEMS A BIT WEAK/LACKING ACROSS MUCH OF CENTRAL AND EASTERN NORTH DAKOTA SO FAR THIS AFTERNOON/EARLY EVENING. IN THIS REGARD LATEST 18Z NAM/GFS AND 12Z ECMWF LOOK A BIT OVERDONE WITH QPF FOR THE EVENING HOURS. ACROSS THE WEST...SCATTERED THUNDERSTORMS IN MONTANA WILL SOON BE MOVING INTO WESTERN NORTH DAKOTA. ISOLATED STRONG THUNDERSTORMS APPEAR POSSIBLE THIS EVENING. MID LEVEL LAPSE RATES LOOK TOO WEAK IN THE CENTRAL AND EAST TO SUPPORT STRONG THUNDERSTORMS THIS EVENING. ADJUSTED POPS DOWN TO SLIGHT CHANCE FOR THE EVENING CENTRAL-EAST. && .SHORT TERM...(THIS EVENING THROUGH THURSDAY) ISSUED AT 247 PM CDT WED JUL 1 2015 CURRENTLY...A WEAK SURFACE RIDGE EXTENDED FROM SOUTHWESTERN SASKATCHEWAN SOUTHEASTWARD ACROSS NORTH DAKOTA INTO CENTRAL MINNESOTA. WEAK SURFACE LOWS WERE CENTERED ON EITHER SIDE OF THE RIDGE...ONE IN WYOMING AND THE OTHER OVER CENTRAL MANITOBA/SASKATCHEWAN. AT UPPER LEVELS...NORTHWEST FLOW CONTINUED ACROSS THE STATE WITH WEAK UPPER LEVEL IMPULSES MOVING SOUTHEAST THROUGH THE FLOW. THIS HAS MAINTAINED MID-LEVEL CLOUDINESS WHICH OVERLAYS LOWER LEVEL CLOUDS RESULTING FROM DISSIPATING FOG AND PLENTY OF LOW LEVEL MOISTURE WITH DEWPOINTS ACROSS THE STATE AROUND 60F. VERY SMALL-SCALE RAIN SHOWER CELLS HAD DEVELOPED OVER SOME PARTS OF CENTRAL NORTH DAKOTA DURING THE PAST COUPLE OF HOURS. AN UPPER LEVEL SHORTWAVE WAS EVIDENT ON SAT PICS OVER SOUTHERN ALBERTA/SASKATCHEWAN AND ACROSS THE NORTHERN BORDER OF MONTANA. REGIONAL RADARS WERE PICKING UP SCATTERED SHOWERS AND THUNDERSTORMS OVER THIS REGION. THIS FEATURE IS FORECAST TO MOVE SOUTHEASTWARD INTO NORTH DAKOTA TONIGHT...WITH UPPER LEVEL IMPULSES FROM THIS SHORTWAVE CONTINUING THROUGH THURSDAY. EXPECTING SCATTERED SHOWERS AND THUNDERSTORMS TO CONTINUE TO DEVELOP LATE THIS AFTERNOON AND EVENING...WITH THE CONVECTION OVER ALBERTA/SASK/MT TO REACH WESTERN NORTH DAKOTA THIS EVENING. THE BEST FORCING FOR STRONG STORMS IS MAINLY CONFINED TO SOUTHWESTERN NORTH DAKOTA. THIS IS WHERE INCREASING BULK SHEAR VALUES ARE FORECAST RESULTING IN PART FROM AN APPROACHING MID-LEVEL JET STREAK. THE BEST CAPE IS ACROSS SOUTHERN NORTH DAKOTA...WITH BETTER CAPE VALUES FARTHER SOUTH INTO SOUTH DAKOTA AND NEBRASKA. DO NOT EXPECT ANY WIDESPREAD STRONG TO SEVERE STORMS...BUT THERE MAY BE ISOLATED STRONG STORMS THIS EVENING SOUTHWEST. OTHERWISE PARTLY TO MOSTLY CLOUDY WITH SCATTERED SHOWERS AND THUNDERSTORMS TONIGHT AND THURSDAY. LOWS TONIGHT AROUND 60...AND HIGHS THURSDAY FROM THE MID 70S TO LOWER 80S. DESPITE LOW LEVEL MOISTURE...THINKING THAT MIXING OF THE ATMOSPHERE AND INCREASING MID TO UPPER LEVEL CLOUDS MAY KEEP DENSE FOG FROM FORMING. CONFIDENCE NOT HIGH ENOUGH BUT WILL MENTION PATCHY FOG OVER THE WEST HALF OF THE STATE. .LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY) ISSUED AT 247 PM CDT WED JUL 1 2015 A FEW THUNDERSTORMS MAY LINGER ACROSS SOUTHEASTERN NORTH DAKOTA AS THE THE SURFACE TROUGH PUSHES OUT THURSDAY EVENING. THE MAIN FOCUS THEN SHIFTS TO THIS WEEKEND. A DEEP SURFACE LOW IS FORECAST TO MOVE SLOWLY EAST ACROSS CANADA THIS WEEKEND INTO NEXT WEEK. STRONG WAA AND COMPRESSIONAL COOLING AHEAD OF THE LOW/COLD FRONT WILL BOOST TEMPERATURES INTO THE 80S AND LOW 90S SATURDAY. THE UPPER LEVEL LOW WILL MOVE EAST ACROSS SASKATCHEWAN AND MANITOBA SAT NIGHT - SUNDAY NIGHT. THIS WILL FORCE A STRONG COLD FRONT TO PUSH SOUTHEAST ACROSS NORTH DAKOTA AND WILL BE THE FOCUS FOR WIDESPREAD SHOWERS AND THUNDERSTORMS. A FEW STRONGER STORMS WILL BE POSSIBLE SATURDAY LATE AFTERNOON AND EVENING AS INSTABILITY INCREASES DURING PEAK HEATING. HOWEVER...IT APPEARS THE BEST SHEAR WILL BE FURTHER WEST...THEREFORE WIDESPREAD STRONG/SEVERE STORMS IS NOT ANTICIPATED AT THIS TIME. SECONDARY COLD FRONT SUNDAY NIGHT INTO MONDAY WILL SEE HIGHS MAINLY IN THE 70S FOR MONDAY. WARMING TREND TOWARDS MID-WEEK AS RIDGING TRIES TO REBUILD ACROSS THE ROCKIES. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING) ISSUED AT 905 PM CDT WED JUL 1 2015 MAIN HAZARDS TO AVIATION CONTINUE TO BE SCATTERED THUNDERSTORMS MAINLY FROM KISN-KDIK AND KBIS TO KJMS THIS EVENING. TSRA STILL TOO UNCERTAIN SO WILL MAINTAIN WEATHER WATCH AND KEEP VICINITY IN FOR THUNDERSTORM LOCATIONS. SMOKE REDUCING VSBYS TO 3 TO 5 MILES AT TIMES NORTHWEST AND NORTH CENTRAL. && .BIS WATCHES/WARNINGS/ADVISORIES... NONE. && UPDATE...WAA SHORT TERM...JV LONG TERM...AJ AVIATION...WAA
