NATIONAL WEATHER SERVICE EASTERN ND/GRAND FORKS
241 PM CDT TUE AUG 8 2000

...TEMPS ONLY FORECAST CONCERN AFTER EVE TSRA DIMINISHES...

BUSY MID/LATE AM AS SVR TSRA FIRED UP ON ERN EDGE OF CWA AHEAD OF
SFC TROF AND U/L S/W HEADING SE INTO NW MN. W/V SHOWS GOOD U/L JET
PLOWING INTO AREA WITH STRONG H25 DIVERGENCE. H85 THETA-E RIDGING
AHEAD OF TROF AND CONVERGENCE IN LOW LEVELS AIDED STORM DEVELOPMENT
WITH MAIN ACTION NOW EAST OF CWA. HOWEVER...CLOSED POCKET OF H5 -14C
AIR IN NRN RRV IN CIRCULATING COLD POOL AND TRAILING WEAK SFC LO IN
NW MN FUELING ANOTHER SMALL AREA OF TSRA THRU LATE AFTN WHERE LI/S
ARE AS LOW AS -9C.

.SHORT TERM...
WEAK H85 CAA ARRIVING INTO ERN ND/NW MN THIS EVE AS LO GETS WRAPPED
UP IN SE MANITOBA SO CU FIELD/-TSRA COULD LINGER INTO FAR NW MN INTO
EVE. WL INCLUDE EVE -TSRA IN SELECTED SPOTS. U/L LO BEGINS TO OPEN
UP AS IT SAILS INTO ONTARIO ALLOWING HEIGHTS TO RISE OVER ND
TONIGHT. SFC HI PRES SETTLES TO NEAR KBIS BY 12Z WITH GOOD
SUBSIDENCE AND LIGHT WIND. CUD BE PATCHY BR IN SPOTS...ESP WHERE
MOST RAIN FELL. U/L JET STREAK MOVES THRU SE ND INTO NE SD
OVNGT...BUT ONLY A FEW MID CLOUDS EXPECTED TO ACCOMPANY FEATURE.
TD/S EXPECTED TO DROP TO NEAR 50F IN FAR WRN CWA WHERE COOLEST TEMPS
MAY BE FOUND CLOSER TO HI PRES AND DRIEST GROUND. FWC/MAV IN GOOD
AGREEMENT AND WILL STAY CLOSE.

.LONG TERM...
MODELS QUITE SIMILAR INDICATING QUIET WX PERIOD WED-THU AS STRONG
RIDGING MOVES OVER NRN PLAINS. ALTHO HEIGHTS BUILD THRU WED...H85
THERMAL/THICKNESS TROF HANGS OVER RRV AND NW MN WITH N/NW FLO THRU
COLUMN. COOLEST TEMPS CONTINUE FROM H7-H5 IN NW MN SO AT LEAST SCT
CU SHOULD FORM THERE. OTHERWISE...K INDICES AROUND 10 AND SLOW LAPSE
RATES SHOULD SUPPORT A NEARLY CLOUDLESS SKY ESP W OF RRV WITH TEMPS
NEAR SEASONAL. THINK FWC MIGHT BE TOO BULLISH ON HI TEMPS AND LIKE
ETA SFC READINGS BETTER AS OVERALL TEMP PROFILE DOES NOT SUPPORT
TEMPS THAT HIGH UNDER LGT FLO. CLEAR/CALM WED NGT WITH RETURN FLO
SETTING UP IN FAR WRN CWA LATE. H85 RIDGE AXIS SHIFTS EAST DURING
THU ALLOWING WAA TO INCREASE. ETA INDICATES LLJ DEVELOPING BY 00Z
FRI WITH 30KTS IN RRV AND TD/S GETTING BACK INTO LOWER 60S. INITIAL
VORT RIDES UP RIDGE TO NEAR KDIK AS AXIS HOLDS OVER NRN RRV.
HOWEVER...SFC BOUNDARY STILL IN CNTRL/ERN MT AND H7 TEMPS SOAR TO
12C PROVIDING SIG CAPPING THIS FAR EAST WITH SOUNDINGS INDICATING
GOOD CIN VALUES AND CONVECTIVE TEMPS NEAR 100F. SOME MID/HI CLOUDS
COULD ADVANCE INTO WRN ZONES BY AFTN SO WL GO PSUNNY THERE AND
MSUNNY AGAIN RRV AND EAST. TEMPS WILL BE BUOYED BY BETTER MIXING AND
WILL GO NEAR 90 SOME SPOTS...BUT WILL GO CLOSER TO MAV INSTEAD OF
EXTREME FWC WITH SE FLO NOT CONDUCIVE FOR MIDDLE 90S HERE.

.EXTENDED...
PATTERN COULD DVLP INTO A STORMY ONE AS LARGE HGTS BLD ACRS CNTRL US
AND SW ORIENTED JET MOVS ACRS NRN PLAINS.  FAST MOVG SHRTWVS SHOULD
HV PLENTY OF MSTR AND HEAT TO WORK WITH.  WILL CONTINUE TREND OF SCT
TSTMS THRU THE PD WITH TEMPS NEAR OR ABV CLIMO.

.FGF...NONE.
