Area forecast discussion, Sep 6, 1:00 PM CDT, 1 hour 58 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
100 PM CDT SUN SEP 6 2015

.UPDATE...
ISSUED AT 1255 PM CDT SUN SEP 6 2015

NO SIGNIFICANT UPDATES PLANNED FOR THE EARLY AFTERNOON. SCATTERED
SHOWERS AND THUNDERSTORMS SHOULD PERSIST ACROSS THE SOUTHERN RRV
AND INTO WEST CENTRAL AND NORTHWEST MINNESOTA INTO MID
AFTERNOON... WITH AN INCREASE IN ACTIVITY EXPECTED AS DAYTIME
HEATING PEAKS ...AHEAD OF THE QUASISTATIONARY FRONT... IN CENTRAL
AND NORTHCENTRAL MN LAKES COUNTRY.

&&

.SHORT TERM...(TODAY THROUGH MONDAY)
ISSUED AT 340 AM CDT SUN SEP 6 2015

FORECAST CHALLENGE FOR THE SHORT TERM WILL BE ONGOING
CONVECTION EXITING THE CWA TO THE EAST AND ENTERING THE CWA
TO THE WEST. THE WESTERN ACTIVITY IS ASSOCIATED WITH A SFC
TROF/FRONT ROUGHLY ALONG A NORTHGATE TO MINOT TO STEELE TO
ASHLEY LINE...WITH MAJORITY OF CONVECTION IN N CNTRL ND.
HRRR HAS A DECENT HANDLE ON WRN ACTIVITY BUT MAY BE A BIT TOO
FAR WEST...IN GENERAL CLIPPING THE FAR NORTHWESTERN PORTION OF
THE CWA. WILL FOLLOW HRRR GUIDANCE BUT BRING CATEGORICAL POPS
FURTHER EAST AND JUST WEST OF DEVILS LAKE. HRRR DOES LIFT THIS
ACTIVITY OUT OF CONUS AND INTO MB BY 13Z.

FOCUS FOR AFTERNOON WILL BE HOW MUCH LOW LEVEL CLOUD CAN SCOUR
OUT AND TIMING FRONT INTO NW AND W CNTRL MN...WHICH SHOULD ARRIVE
IN FAR EASTERN ZONES NEAR PEAK HEATING. THE NAM CONTINUES TO SHOW
MUCAPES OF AROUND 1500 TO 2200 J/KG (HRRR VALUES ARE SIGNIFICANTLY
LESS) WITH BULK SHEAR AROUND 40 KTS IN THE HIGHEST CAPE AND
SLIGHTLY HIGHER BEHIND THE SFC BOUNDARY. CURRENT SPC SLIGHT RISK
AREA IS ALONG FAR EASTERN COUNTIES ALONG AND AHEAD OF
FRONT...HOWEVER NAM TIMING WOULD DRAG THE SEVERE POTENTIAL BACK
FURTHER INTO OTTER TAIL COUNTY ALONG THE SOUTHERN END OF THE
BOUNDARY. WILL MAKE LITTLE CHANGE TO PREV POPS FOR AFTN HOURS.

FRONT SHOULD EXIT CWA BY EVENING AND DRY WEATHER EXPECT FROM MID
EVENING THROUGH THE OVERNIGHT PERIOD...WITH COOL AND DRY AIR IN
THE MID 40S MOVING INTO NW ZONES.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 340 AM CDT SUN SEP 6 2015

MON NIGHT...SW FLOW ALOFT TURNING MORE ZONAL BY TUE MORNING.
A WEAK VORT MAX AND SWT ASSOCIATED WITH UPPER LOW OVER NRN
MANITOBA BRINGING A CHANCE OF WEAK SHOWERS IN THE FAR
NORTHEAST...AND WILL KEEP LOW POPS PER GOOD AGREEMENT BETWEEN
ECMWF/GFS/NAM SOLUTIONS. MAJORITY OF AREA HOWEVER WILL BE DRY
WITH MUCH COOLER AIR ENTERING FAR NW...OVERNIGHT LOWS IN THE
MID 40S AROUND LANGDON.

TUE AND TUE NIGHT...ZONAL FLOW WITH MODELS SHOWING A SFC LOW
ENTERING NORTH DAKOTA TUE NIGHT...ALTHOUGH SIGNIFICANT DIFFERENCE
ON TRACK OF LOW WITH NAM SHOWING SFC LOW OVER SRN SASK AT 12Z WED
COMPARED TO ECMWF IN CNTRL ND AND MORE BULLISH WITH SHOWERS. WILL
BRING LOW POPS INTO DVL BASIN BUT CONFIDENCE IS LOW ATTM.

WEDNESDAY THROUGH SATURDAY...MODELS GENERALLY AGREE WITH THE
OVERALL PATTERN PLACING THE REGION ON THE SOUTHERN END OF A STRONG
UPPER LOW PROPAGATING THROUGH CANADA. MOSTLY A DRY PERIOD...ALTHOUGH
ANY SHORTWAVES ROTATING THROUGH COULD LEAD TO BRIEF SHOWER CHANCES
(BEST CHANCES WED AND FRI). TEMPERATURES A BIT BELOW NORMAL
TRANSITIONING BACK TOWARD NEAR NORMAL VALUES.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 1255 PM CDT SUN SEP 6 2015

SURFACE TROUGH AXIS /QUASISTATIONARY FRONT/ CURRENTLY LOCATED
JUST EAST OF THE RED RIVER...AND RADAR SHOWS SOME INCREASED
THUNDERSTORM DEVELOPMENT JUST BEHIND IT NEAR KGFK AND KFAR. WILL
INCLUDE VCTS MENTION FOR THE NEXT HOUR OR SO...THEN TRANSITIONING
TO NEAR KTVF AND KBJI LATER THIS AFTERNOON. CIGS AND VIS WILL BE
ALL OVER THE PLACE AS THE THUNDERSTORMS AND THE TROUGH AXIS MOVES
THROUGH. A WEAK COLD FRONT WILL BE MOVING IN BEHIND THE TROUGH
AXIS...AND KDVL HAS ALREADY SEEN WINDS SHIFT TO THE WEST NORTHWEST
AND BECOME RATHER GUSTY. THERE ARE SOME MVFR CIGS BETWEEN THE SFC
TROUGH AXIS AND THE FRONT...BUT COVERAGE IS RATHER SPOTTY SO WILL
LEAVE OUT FOR NOW AND AMEND AS NEEDED. THE FRONT SHOULD BE NEAR
THE RED RIVER BY LATE AFTERNOON AND INTO THE EASTERN FORECAST AREA
BY EARLY EVENING. VFR CONDITIONS BEHIND THE FRONT WITH WEST WINDS
SETTLING DOWN OVERNIGHT THEN SHIFTING AROUND TO THE SOUTHWEST TO
