AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GRAND FORKS ND
1004 AM CDT FRI JUL 4 2014

.UPDATE...
ISSUED AT 1004 AM CDT FRI JUL 4 2014

INTERESTING SET-UP FOR THIS AFTERNOON AND EVENING. QUICK MOVING
SHORT-WAVE CURRENTLY ACROSS NORTHEAST MT/NORTHWEST ND WILL MOVE
THROUGH BROAD 500 HPA RIDGE AND ACROSS THE FORECAST AREA THIS
AFTERNOON AND EVENING. IMMEDIATELY AHEAD OF THIS WAVE...RAP IS
SHOWING AN AREA OF 0 TO 6 KM BULK SHEAR FROM 40 TO 45 KTS.
BOUNDARY LAYER IS INITIALLY WELL CAPPED THROUGH 18-19 UTC...
ERODING THEREAFTER WITH UPWARDS OF 1500 TO 2500 J/KG OF MLCAPE
ALONG AND WEST OF THE VALLEY. FURTHER EAST...INSTABILITY IS LESS
BUT STILL AROUND 500 J/KG BY MID-AFTERNOON. CONVECTIVE
TEMPERATURES ARE IN THE UPPER 80S TO LOW 90S...BUT THERE EXIST
STEEP MID-LEVEL LAPSE RATES. 0 TO 3 KM VGP VALUES RISE QUICKLY TO
BETWEEN 0.3 AND 0.5 ACROSS NORTHEAST ND INTO NORTHWEST MN. GIVEN
ALL THESE FACTORS...SPC DAY ONE SLIGHT RISK AREA LOOKS GOOD. MAIN
QUESTION WILL BE IF PRIMARY FORCING ALOFT MOVES THROUGH BEFORE
INSTABILITY/SHEAR IS MAXIMIZED AFTER THE CAP ERODES.

WILL KEEP SEVERE WORDING IN THE GRIDS AND UPDATE POPS TO REFLECT
LATEST TRENDS FROM THE RAP/HRRR...BOTH SHOWING INCREASING SHOWERS
AND THUNDERSTORMS (SOME OF WHICH MAY BE STRONG TO SEVERE) FROM
WEST TO EAST THIS AFTERNOON AND EVENING MAINLY ACROSS NORTHEAST ND
INTO NORTHWEST MN. STORMS SHOULD BE EAST OF THE VALLEY BY LATE
EVENING. OTHERWISE...TODAY WILL BE WARM AND BREEZY WITH HIGH
TEMPERATURES IN THE UPPER 70S TO LOWER 80S AND A STIFF SOUTHERLY
WIND WITH GUSTS UP TO 30 MPH AT TIMES.

UPDATE ISSUED AT 650 AM CDT FRI JUL 4 2014

ISOLATED THUNDERSTORM CELLS CONTINUE TO FIRE FROM NERN SD INTO
FAR SERN ND AND THE EDGE OF WCNTRL MN. STILL EXPECT THESE CELLS TO
INCREASE IN COVERAGE AND LIFT NORTHEASTWARD THROUGH THE MORNING...
REACHING INTO THE FARGO-MOORHEAD AREA THROUGH THE FORENOON.
ELSE... NO SIG CHANGES TO THE FCST PACKAGE ATTM.

&&

.SHORT TERM...(TODAY THROUGH SATURDAY)
ISSUED AT 359 AM CDT FRI JUL 4 2014

ISOLATED THUNDERSTORMS ARE FIRING ACROSS NORTHEAST SD THIS EARLY
MORNING ALONG AN ELEVATED BAND OF INSTABILITY...WITH A FEW HUNDRED
J/KG OF CAPE SHOWING. RUC AND HRRR HAVE THIS BAND PERSISTING THRU
MID MORNING AS IT EXPANDS ACROSS SERN ND INTO WEST CENTRAL MN.

THEN THIS BAND CONTINUES TO LIFT INTO NERN ND AND NORTHWEST
MN BY MIDDAY...WHERE SURFACE HEATING AND INCREASING LOW LEVEL
SHEAR LEAD TO FAIRLY ROBUST LOW LEVELS CAPE /+500 J/KG/ AND LOW
LEVEL /0 TO 2 KM LAYER/ VGP EXCEEDING 0.2 UNITS. SPC HAS
IDENTIFIED THIS AREA AS A SLIGHT RISK FOR SEVERE WEATHER WITH A 5
PERCENT RISK OF A TORNADO OR TWO. WOULD EXPECT THIS THREAT TO BE
MAINLY ALONG AND WEST OF THE RED RIVER FROM MID AFTERNOON ON...
SHIFTING INTO NORTHWEST MN FROM LATE AFTERNOON THROUGH SUNSET.
A CHASER SHOWER OR TWO IS POSSIBLE DURING THE OVERNIGHT PERIOD.

MODELS ARE GENERALLY DRY ON SATURDAY.. WITH MOTTLED CLOUD COVER
AND SOMETHING OF A STRENGTHENING CAPPING INVERSION THROUGH THE
DAY. AN APPROACHING MID LVL SHORTWV TROF LOOKS TO DISRUPT THAT CAP
STARTING INTO NORTHWEST ND BY LATE AFTERNOON... AND PROGRESSING
INTO NORTHEAST ND LATE SATURDAY EVENING.

.LONG TERM...(SATURDAY NIGHT THROUGH THURSDAY)
ISSUED AT 359 AM CDT FRI JUL 4 2014

SATURDAY NIGHT THROUGH SUNDAY...THERE HAS BEEN...A SIGNAL AMONG
MOST MODELS INDICATING THE POTENTIAL FOR A STRONGER SHORTWAVE
SATURDAY NIGHT ROUNDING THE RIDGE. THIS WAVE WOULD BE STRONG
ENOUGH TO INITIATE CONVECTION...WITH SOME SORT OF MCS SATURDAY
NIGHT. DEEP LAYER SHEAR WOULD BE MUCH STRONGER...WITH THIS SYSTEM
MOVING INTO A VERY UNSTABLE ENVIRONMENT. SPC CONTINUES TO INDICATE
A SLIGHT RISK OF SEVERE STORMS ACROSS THE NORTHERN REGION EARLY ON
SUNDAY.

MONDAY-THURSDAY...DURING THE EARLY STAGES OF THE WEEK...NORTHWEST
FLOW ALOFT WILL AMPLIFY OVER THE NORTHERN PLAINS. MODEL GUIDANCE
SUGGESTS A FEW SHORTWAVE TROUGHS MAY AFFECT THE REGION DURING THE
MON-TUE TIME FRAME...WITH AT LEAST CHANCES FOR SCT SHOWERS/STORMS.
FOR MID TO LATE WEEK...A GRADUAL FLATTENING OF THE FLOW IS EXPECTED.
PRECIP CHANCES MAY DECREASE FOR MID-WEEK WITH LITTLE IN THE WAY OF
UPPER FORCING...AND SFC HIGH PRESSURE BUILDING INTO THE REGION.
GIVEN THE NORTHWEST FLOW...TEMPS SHOULD REMAIN FAIRLY SEASONABLE
THROUGH THE MIDDLE OF THE WEEK...BEFORE WARMING BACK UP BY LATE
WEEK.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z SATURDAY MORNING)
ISSUED AT 650 AM CDT FRI JUL 4 2014

VFR CONDS WITH INCREASING CIRRUS AND MID LEVEL CLOUDS ACROSS THE
FA THROOUGH THE DAY. ISOLD TSTMS IN THE SOUTHERN RED RIVER VALLEY
THROUGH MIDDAY WILL BECOME SCT AND EXPAND ACROSS NERN ND AND NWRN
MN THROUGH THE AFTERNOON. THERE IS A RISK OF SEVERE THUNDERSTORMS
FROM MID AFTERNOON INTO THE EARLY EVENING... BECOMING VFR BY
NIGHTFALL.
