What happened

The episode as NWS FGF wrote it up.

Eastern North Dakota remained in a very weak surface pattern on the 18th, with numerous weak surface lows and boundaries across the midwest. Like the past several days, moisture levels remained very high, with surface dew points in the low to mid 60s. Some morning cloud cover along the North Dakota/South Dakota border lifted north by afternoon, and allowed a period of good heating. Although the upper level winds were fairly light, another in a series of upper level disturbances shifted over the area by mid afternoon. This helped initiate thunderstorm development over southeast North Dakota and west central Minnesota. A cluster of thunderstorms also developed over extreme northeast North Dakota. By late afternoon, a line of thunderstorms raced across the Mooreton (ND) area, through Wahpeton/Breckenridge, and into the Fergus Falls (MN) area. This line of storms brought many reports of strong winds. The weak wind flow and moist atmosphere once again brought heavy rainfall to areas along the Canadian border and areas along and south of Interstate 94.

What forecasters said that day

Area forecast discussion, Jun 18, 9:40 AM CST, 3 hours 20 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GRAND FORKS ND
1040 AM CDT THU JUN 18 2009

.DISCUSSION...
KIND OF A WAIT AND SEE FORECAST FOR TODAY...REALLY NO STRONG
INDICATORS SETTING UP TO HIGHLIGHT ANY ONE AREA WITH BETTER
CHANCES FOR SHOWERS AND TSTMS. CURRENTLY HAVE SOME WEAK SHOWERS
(POSSIBLY A CLAP OF THUNDER) FROM KJMS TO KBWP. THESE HAVE
GENERALLY BEEN WEAKENING AS THEY HAVE BEEN LIFTING TO THE NORTH.
THE THICKER CLOUD COVER ASSOCIATED WITH THIS AREA OF LIGHT RAIN
HAS KEPT THE FOG AROUND AND ALSO KEPT TEMPS FROM RISING AS FAST
THIS MORNING. HOWEVER...JUST TO THE SOUTH OF THE FA...THERE ARE
HARDLY ANY CLOUDS. THEREFORE SD WILL GET A HEAD START ON WARMING
AND BETTER INSTABILITY. LOTS OF MOISTURE OUT THERE TO WORK WITH...
THIS WILL NOT BE A LIMITING FACTOR FOR TSTM DEVELOPMENT IN ANY
AREA. WILL MAINLY BE LOOKING FOR A GOOD SOURCE OF LIFT TO FOCUS
ON TODAY. THE BEST UPPER LEVEL SUPPORT LOOKS TO BE ACROSS OUR
SOUTHERN FA...BUT EVEN MORE SO TO AREAS SOUTH OF THAT. NO REAL
LOW LEVEL JET MAINTAINS ITSELF EITHER DURING THE DAY. THE BEST
850MB THERMAL GRADIENT WILL LIE NEAR THE SFC WARM FRONT DOWN NEAR
KFSD/IOWA BY LATER IN THE DAY. BEST SUPPORT UP IN OUR FA LOOKS TO
BE THE 700MB/500MB SHORT WAVE THAT THE MODELS TRACK INTO THE AREA
BY 00Z FRI. WATER VAPOR IMAGERY SHOWS ONE DISTURBANCE OVER
WESTERN SD THAT WILL NEED TO BE WATCHED THRU THE DAY. ALL
SAID...INHERITED FORECAST IS RIGHT ON TRACK WITH ONLY SOME MINOR
TWEAKS NEEDED. WILL ADJUST CLOUD TRENDS TO MATCH CURRENT
CONDITIONS AND ADD A DEGREE OR TWO TO TEMPS. OTHERWISE...WILL KEEP
THE HIGH CHANCE PCPN FORECAST FOR ALL AREAS WITH THE UNCERTAINTY.
LIKE PREVIOUS FORECAST...UNSURE ON THE SEVERE POTENTIAL AT THIS
POINT (AND FOR WHERE) AND WILL LEAVE IT OUT AS WELL.

&&

.AVIATION...

FOG IS A LITTLE SLOW TO DISSIPATE IN AREAS THAT HAVE THICKER
CLOUDS THIS MORNING...WHICH IS BASICALLY RIGHT ALONG THE
INTERSTATE 94 IN ND/HIGHWAY 10 CORRIDOR IN MN (AFFECTING KFAR AND
KBJI THE MOST). HOWEVER...THESE AREAS SHOULD CONTINUE TO IMPROVE
TOO. SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE AT ALL
TAF SITES TODAY AS A WEATHER DISTURBANCE MOVES ACROSS THE NORTHERN
PLAINS. CERTAINTY NOT GREATER THAN 50 PERCENT TO VALIDATE THE USE
OF TEMPO GROUPS...SO WILL COVER PRECIPITATION THREAT IN 12 UTC TAF
ISSUANCE WITH CB QUALIFIER FOR THE AFTERNOON HOURS. LIGHT SOUTH-
SOUTHEAST WIND WILL PERSIST.

&&

.PREV DISCUSSION... /ISSUED 524 AM CDT THU JUN 18 2009/

UPDATE...

DENSE FOG (1-3 SM) HAS BECOME MORE WIDESPREAD THAN PREVIOUSLY
ANTICIPATED AS CLOUD COVER THINS ALLOWING FOR MAXIMUM NOCTURNAL
COOLING. SOME SPOTS STILL REPORTING VISIBILITY TO 1/4 MILE...
INCLUDING GFK AND TVF. UPDATED GRIDS TO ADD AREAS OF FOG ALONG AND
EAST OF THE RED RIVER VALLEY THROUGH 14 UTC. FOG STILL EXPECTED TO
DIMINISH AFTER SUNRISE.

PREV DISCUSSION... /ISSUED 352 AM CDT THU JUN 18 2009/

DISCUSSION...

PRIMARY FORECAST CHALLENGES INCLUDE RAIN/THUNDERSTORM CHANCES AND
POSSIBLE HEAVY RAIN/SEVERE STORMS LATER THIS AFTERNOON. GFS/NAM
IN GOOD AGREEMENT...BUT WILL LEAN TOWARDS NAM SOLUTION FOR
FORECAST DETAILS GIVEN RECENT BETTER OVERALL PERFORMANCE.

EARLY THIS MORNING...A WEAK LINE OF THUNDERSTORMS HAS DEVELOPED
ALONG A LINE FROM CANDO TO DEVILS LAKE TO TOLNA IN ASSOCIATION
WITH A WEAK UPPER LEVEL WAVE. THESE STORMS ARE CRAWLING TO THE
EAST...BUT THE NUMBER OF LIGHTNING STRIKES HAS DECREASED MARKEDLY
THE PAST HOUR. AM THINKING CONVECTION WILL CONTINUE TO LIMP
EASTWARD THIS MORNING AND WEAKEN AS WAVE EXITS NORTH INTO CANADA
GIVEN CURRENT WATER VAPOR LOOP TRENDS.

ALSO EARLY THIS MORNING...AREAS WITH LITTLE CLOUD COVER ARE SEEING
DENSE FOG WITH VISIBILITIES DOWN TO 1/4 OF A MILE AT GFK AND TVF.
WITH SUNRISE AROUND 530 AM...STRONG JUNE SOLAR SHOULD QUICKLY
BURN OFF FOG. AS SUCH...WILL NOT MENTION IN GRIDS BUT THERE COULD
STILL BE AREAS OF PATCHY DENSE FOG THROUGH 8 AM...ESPECIALLY
ACROSS THE NORTHERN RED RIVER VALLEY.

GFS/NAM BRING NEXT SHORT WAVE FROM WYOMING ACROSS NORTHWEST SOUTH
DAKOTA THIS MORNING AND INTO SOUTH-CENTRAL NORTH DAKOTA LATER THIS
AFTERNOON. WITH NO DISCERNIBLE LOW-LEVEL JET OR NEAR SURFACE
CONVERGENT BOUNDARIES...THIS FEATURE WILL BE THE PRIMARY FOCUS FOR
THUNDERSTORM DEVELOPMENT TODAY. 00 UTC NAM SHOWS 2000 TO 2500 J/KG
OF 0-1 KM MOST UNSTABLE CAPE ACROSS EASTERN NORTH DAKOTA THIS
AFTERNOON WITH LITTLE TO NO CAP. HOWEVER...0-6 KM BULK SHEAR IS
ONLY A MEASLY 5-15 KTS WITH 300 HPA JET FARTHER SOUTH ACROSS
CENTRAL PLAINS. WITH PWATS AROUND 1.25 INCHES AND SLOW STORM
MOTION...AM THINKING PRIMARY THREAT WILL BE HEAVY RAIN. HOWEVER...
ISOLATED STORMS MAY STILL PRODUCE LARGE HAIL. WILL MENTION HEAVY
RAIN IN THE GRIDS ACROSS SOUTHEAST NORTH DAKOTA AND ADJACENT AREAS
OF WEST-CENTRAL MINNESOTA...BUT HOLD OFF ON SEVERE WORDING AS
COVERAGE SHOULD BE LIMITED. IN GENERAL...EXPECT TO SEE SCATTERED
SHOWERS AND THUNDERSTORMS MOVE FROM WEST TO EAST COINCIDENT WITH
UPPER LEVEL WAVE THIS AFTERNOON INTO THIS EVENING.

CHANCE POPS CONTINUE THROUGH FRIDAY AS ONE MORE SHORT WAVE MOVES
THROUGH THE REGION IN SOUTHWEST FLOW ALOFT. HOWEVER...EXPECT A
RETURN TO DRY SUNNY WEATHER SATURDAY AND MUCH OF SUNDAY AS 500 HPA
RIDGE AXIS MOVES OVERHEAD. 850 HPA TEMPERATURES FROM +16 TO +18 C
SHOULD RESULT IN DAYTIME HIGHS AT THE SURFACE IN THE LOW TO MID 80S.
NIGHTS WILL BE PLEASANT WITH TEMPERATURES IN THE UPPER 50S TO LOW
60S.

THE THREAT FOR SHOWERS AND THUNDERSTORMS RETURNS SUNDAY NIGHT INTO
EARLY NEXT WEEK AS FLOW ALOFT TURNS SOUTHWESTERLY ONCE AGAIN AND
THE NEXT PARADE OF SHORT WAVES MOVES THROUGH THE REGION.

.FGF WATCHES/WARNINGS/ADVISORIES...
