AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
1244 PM CDT SUN JUN 7 2015

.UPDATE...
ISSUED AT 1234 PM CDT SUN JUN 7 2015

FORECAST IN GOOD SHAPE WITH CONVECTIVE TEMPS BEING
REACHED...NOTICED BY THE FIRST FEW CELLS POPPING UP IN THE LAST
HOUR IN SOUTHERN MANITOBA AND A SHOWER DEVELOPING IN PEMBINA
COUNTY. EXPECT TO SEE COVERAGE CONTINUE TO INCREASE ACROSS NW MN
AND THE NORTHERN RRV AND ACTIVITY WILL TRACK SE DURING THE
AFTERNOON. GENERAL THUNDER THREATS OF SMALL HAIL...GUSTY WINDS AND
BRIEF DOWNPOURS ARE THE PRIMARY IMPACTS.

&&

.SHORT TERM...(TODAY THROUGH MONDAY)
ISSUED AT 303 AM CDT SUN JUN 7 2015

ANY THUNDERSTORM CHANCES THIS AFTERNOON AND TEMPERATURES
THROUGHOUT THE PERIOD WILL BE THE MAIN FORECAST CONCERNS.

UPPER TROUGH CONTINUES TO DIG INTO THE NORTHERN PLAINS...WITH THE
MAIN SHORTWAVE EXPECTED TO SHIFT EASTWARD INTO MN TODAY. THE SFC
LOW OVER THE EASTERN CWA WILL MOVE OFF AND THERE SHOULD BE A
DECENT GRADIENT WITH NORTHWESTERLY WINDS BEHIND IT. DENSE FOG THIS
MORNING SHOULD QUICKLY SCOUR OUT SHORTLY AFTER SUNRISE. WITH
PLENTY OF SUN...TEMPS SHOULD GET UP INTO THE 70S TO NEAR 80 IN THE
WEST. WITH WARM SFC TEMPS AND FAIRLY COOL AIR ALOFT...THERE SHOULD
BE SOME PRETTY STEEP LAPSE RATES DEVELOPING AND MODELS ARE SHOWING
1500-2000 J/KG OF CAPE BY THIS AFTERNOON. HOWEVER...DEEP LAYER
BULK SHEAR VALUES ARE ONLY AROUND 25KTS SO NOT REALLY EXPECTING
ANY SEVERE. KEPT SOME ISOLATED TO SCATTERED POPS GOING FOR THIS
AFTERNOON WITH HIGHEST VALUES IN THE NORTHEASTERN COUNTIES.

TONIGHT...ANY CONVECTION WILL QUICKLY DISSIPATE AFTER SUNSET AS WE
LOSE HEATING. NORTHWEST SFC WINDS WILL CONTINUE AND SHOULD KEEP
SOME MIXING GOING. WILL CONTINUE TO KEEP LOWS IN THE MID TO UPPER
50S OVERNIGHT. THE QUIET WEATHER WILL CONTINUE INTO TOMORROW WITH
NORTHWESTERLY FLOW ALOFT AND EVEN WARMER AIR MOVING INTO THE AREA.
THINK THAT HIGHS WILL REACH THE 80S AT LEAST FROM THE RED RIVER
VALLEY WESTWARD.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 303 AM CDT SUN JUN 7 2015

MONDAY NIGHT THROUGH TUESDAY NIGHT...NORTHWESTERLY FLOW ALOFT
CONTINUES WITH A SHORTWAVE MOVING THROUGH SOUTHERN CANADA. THE
SHORTWAVE WILL HELP PUSH A COLD FRONT THROUGH THE CWA
TUESDAY...AND MODELS BREAK OUT SOME PRECIP ALONG THE BOUNDARY.
STILL SOME VARIATION ON EXACTLY HOW MUCH COVERAGE SO KEPT POPS
MODEST FOR NOW AND CAN TAKE ANOTHER LOOK LATER ON. EVEN WITH A
COLD FRONT MOVING THROUGH TUESDAY THERE SHOULD BE DECENT WARMING
PARTICULARLY IN THE SOUTH WHERE 850MB TEMPS IN THE 20S C STICK
AROUND LONGER. KEPT HIGHS IN THE UPPER 70S AND 80S. SFC HIGH
BEHIND THE BOUNDARY TUESDAY NIGHT SHOULD HELP THE LOWS DROP INTO
THE LOW TO MID 50S.

WEDNESDAY-SATURDAY...WEDNESDAY LOOKS MAINLY DRY WITH SEASONABLE
TEMPS UNDER WEAK HIGH PRESSURE AND FAIRLY ZONAL FLOW ALOFT.

THE GLOBAL MODELS CONTINUE TO SHOW A CONSISTENT SIGNAL FOR
CONVECTION ACROSS PARTS OF THE NORTHERN PLAINS LATER WED INTO
THU....AS UPPER LEVEL ENERGY INTERACTS WITH A LOW-LEVEL BAROCLINIC
ZONE...WITH STRONG NORTHWARD MOISTURE TRANSPORT. HOWEVER...THE
GFS/GEM/ECMWF DIFFER ON PLACEMENT OF UPPER SHORTWAVE TROUGHS
EJECTING FROM A DIFFUSE WESTERN TROUGH. THE 00Z ECMWF KEEPS MUCH OF
THE PRECIP SOUTH TOWARDS THE SD BORDER...WHILE THE GFS IS A BIT
FARTHER NORTH. TEMPS THURSDAY WILL HINGE ON CLOUDS/PRECIP.

LOWER CONFIDENCE BY LATE IN THE PERIOD. WEAK RIDGING ALOFT IS
PROGGED WITH NO STRONG PRECIP SIGNAL OVER THE AREA...ALTHOUGH THE
GFS/ECMWF DO INDICATE SOME UPPER LEVEL ENERGY REMAINING OVER PARTS
OF THE PLAINS/MIDWEST. TEMPS SHOULD BE SEASONABLE.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 1234 PM CDT SUN JUN 7 2015

VFR CIGS TO BECOME SCT-BKN AS TEMPERATURES RISE TO CONVECTIVE
VALUES. SHOWERS AND TSRA TO BECOME MORE SCT AS THE AFTERNOON GOES
ON. CANNOT RULE OUT SOME SMALL HAIL AND GUSTY WINDS WITH STRONGER
STORMS. STORMS AND CIGS TO DIMINISH THIS EVENING WITH LOSS OF
HEATING.
