AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
644 PM CDT WED JUN 4 2014

.UPDATE...
ISSUED AT 635 PM CDT WED JUN 4 2014

FORECAST CHALLENGES THROUGH THE EVENING UPDATE PERIODS WILL BE
MONITORING EASTWARD PROPAGATION OF CONVECTION ASSOCIATED WITH WAVE
OVER NW ND. MODEST INSTABILITY AND SOME CAPE GRADUALLY SPREADING
EAST WITH LTG STRIKES SPREADING INTO FAR NW FA. LACK OF LOW LEVEL
JET AND SHEAR SHOULD LIMIT MAIN POTENTIAL FOR CONVECTION PRIOR TO
SUNSET WITH BEST POTENTIAL ACROSS THE NORTH IN BETTER LOW LEVEL
CONVERGENCE AND PROXIMITY TO UPPER WAVE. MAIN TROUGH REMAINS
ACROSS E MT AND WILL ALSO BE MONITORING CONVECTION AS THIS SHIFTS
EAST. SPREAD POPS A LITTLE FARTHER EAST EARLY THIS EVENING
OTHERWISE CURRENT FORECAST LOOKING GOOD.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY NIGHT)
ISSUED AT 305 PM CDT WED JUN 4 2014

MAIN FORECAST CHALLENGE WILL CONTINUE TO BE PCPN CHANCES. MODELS
CONTINUE TO ADVERTISE AN UNSETTLED PATTERN WITH GENERALLY ZONAL
FLOW. AS OF LATE AFTERNOON WATER VAPOR IMAGERY INDICATED UPPER
LEVEL DIVERGENT FLOW OVER NORTHERN ND. SPC MESO PAGE CORRELATED
THE CURRENT SHOWERS/TSTMS OVER NORTHEAST ND IN THE MAXIMIZED
DIVERGENT AREA. STILL EXPECT THESE INITIAL SHOWERS/TSTMS TO DRIFT
INTO THE NORTHERN RED RIVER VALLEY OVER THE NEXT FEW HOURS AND
WEAKEN OR MOVE INTO SOUTHERN CANADA. BEHIND THIS INITIAL BATCH OF
PCPN THERE ARE OTHER SPOTTY SHOWERS/TSTMS OVER NORTHWEST ND AND
MORE WIDESPREAD ECHOES OVER EASTERN MT. THE MAIN UPPER WAVE IS
BACK OVER EASTERN MT AND EXPECT THIS TO SLOWLY DRIFT TO THE EAST
TONIGHT AND BRING MORE SHOWERS/TSTMS TO THE AREA. TIMING LOOKS A
LITTLE SLOWER THAN IT DID YESTERDAY WITH THE WAVE GETTING INTO
THE KDVL REGION AROUND MIDNIGHT AND INTO THE RED RIVER VALLEY
NEAR 12Z THU. WITH LOSS OF HEATING CAPE VALUES ALSO DIMINISH AFTER
SUNSET AND THERE IS NOT MUCH OF A LOW LEVEL JET TONIGHT. BULK
SHEAR VALUES ARE ALSO PRETTY LOW. THEREFORE ANTICIPATE WEAKENING
STORMS REACHING OUR FA TONIGHT. THE SHORT WAVE WILL MOVE INTO
NORTHWEST MN ON THU MORNING. IF THE CLOUDS ASSOCIATED WITH
TONIGHTS CONVECTION PASS OFF TO THE EAST AND ALLOW SOME SFC
HEATING THERE SHOULD BE SOME REGENERATION OF TSTM ACTIVITY THU
AFTERNOON. THE AREA REMAINS IN GENERAL THUNDER BUT NO SLIGHT RISK
FOR DAY2 MOST LIKELY DUE TO THE CONTINUED LACK OF BULK SHEAR. MAY
BE SOME LINGERING PCPN THU NIGHT WITH MODELS BROAD BRUSHING THE
AREA...SO WILL KEEP CHANCES LOW. MAIN FORCING LOOKS TO BE A COLD
FRONT PASSING THRU.

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 305 PM CDT WED JUN 4 2014

COLD FRONT MENTIONED ABOVE WILL BRING MUCH COOLER WEATHER FOR FRI
AND SAT WITH HIGHS IN THE 60S. MODELS CONTINUE TO BROADBRUSH MOST
OF THE FA WITH PCPN ALTHOUGH THE FAR NORTH SHOULD STAY DRY.

FOR SAT NIGHT THROUGH WED...LONG TERM MODELS ARE DECENTLY IN
AGREEMENT WITH A DEPARTING SFC HIGH EARLY IN THE PERIOD. FROM LATE
SUNDAY ON THE LONG TERM MODELS GRADUALLY DIVERGE MORE AND MORE. A
ZONAL PATTERN WILL CONTINUE A SERIES OF WAVES AND AN ACTIVE
PERIOD...HOWEVER THE GFS HAS HIGHER AMPLITUDE WAVES AND ENDS UP
HAVING A CLOSED LOW OVER NORTHEAST MB / WRN ONTARIO BY DAY 6/7
WHILE THE GFS SHOWS A WIDE OPEN WITH CENTRAL PLAINS LOW EXTENDING
A SFC TROUGH THROUGH MINNESOTA ON DAY 7. THIS GIVES THE HPCALL
SOLUTION LIKELY POPS...WHICH I HAVE REMOVED FOR MUCH OF THE CWA AS
CONFIDENCE IS VERY LOW THIS FAR OUT AND MODELS OUT OF PHASE.
SEASONAL TO SLIGHTLY COOLER THAN SEASONAL TEMPS CAN BE EXPECTED
THROUGHOUT THE PERIOD.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 633 PM CDT WED JUN 4 2014

WILL MAINTAIN VFR CIGS OVERNIGHT AND FOR THE EVENING CURRENT
CONVECTION PRETTY SPOTTY SO LIMITED ANY MENTION TO VCNTY AT DVL.
WILL MONITOR TRENDS BUT ANY CONVECTION SHOULD DIMINISH WITH LOSS
OF HEATING WITH MAINLY SHRA AFFECTING THE FA OVERNIGHT.
