AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
1103 AM CDT FRI JUN 21 2013

.UPDATE...
ISSUED AT 1100 AM CDT FRI JUN 21 2013

WILL ALLOW THE DENSE FOG ADVISORY TO EXPIRE AT 11 AM CDT.
VISIBILITIES CONTINUE TO IMPROVE ACROSS WEST AND CENTRAL NORTH
DAKOTA. PATCHY AREAS OF FOG MAY LINGER INTO THE AFTERNOON SOME
LOCATIONS WITH VERY HIGH BOUNDARY LAYER MOISTURE IN PLACE...WITH
SURFACE DEWPOINTS IN THE 60S TO EVEN AROUND 70F SOME LOCATIONS.

LATEST RAP (13Z AND 14Z RUNS) SEEMS TO BE DOING THE BEST SO FAR
WITH CURRENT SHOWERS AND STORMS...WEST AND SOUTH WITH THE HEAVIER
ECHOS SOUTHWEST OVER ADAMS AND HETTINGER COUNTIES.

SKIES SHOULD REMAIN MAINLY CLOUDY THROUGHOUT THE DAY ALONG WITH
CHANCES FOR SHOWERS AND THUNDERSTORMS...SOME SEVERE...WITH
NUMEROUS EMBEDDED WAVES LIFTING ACROSS THE DAKOTAS. BEST CHANCE
FOR WIDESPREAD CONVECTION WITH SEVERE WEATHER AND HEAVY RAIN WILL
BE MID/LATE AFTERNOON INTO THIS EVENING WITH PEAK HEATING AND
INSTABILITY MAXIMIZED. MODELS ARE KEYING IN ON CONVECTION FIRING
UP ACROSS SOUTH DAKOTA LIFTING NORTH AND EAST TODAY INTO THIS
EVENING...WITH A DRY/QUIET PERIOD IN THE WAKE OF THIS ACTIVITY
LATE TONIGHT. WITH RICH BOUNDARY LAYER MOISTURE REMAINING IN
PLACE...REDEVELOPMENT OF FOG AND STRATUS IS LOOKING LIKELY ONCE
SKIES TREND SCT-SKC.

UPDATE ISSUED AT 908 AM CDT FRI JUN 21 2013

MAIN UPDATE WAS TO EXTEND THE DENSE FOG ADVISORY UNTIL 11 AM CDT
WITH SEVERAL AREA OBSERVING SITES REPORTING 1/4 MILE OR LESS STILL.

UPDATE ISSUED AT 618 AM CDT FRI JUN 21 2013

UPDATE TO ISSUE DENSE FOG ADVISORY FOR PORTIONS OF THE FORECAST
AREA AS OBS/WEBCAMS/SPOTTER REPORTS INDICATING DENSE FOG COVERAGE
IS NOW SIGNIFICANT...AND WARRANTS HEADLINES. ALSO INCREASED POPS
SLIGHTLY FAR WEST PER LATEST RADAR TRENDS.

&&

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 402 AM CDT FRI JUN 21 2013

THE HIGHLIGHT OF THE SHORT TERM IS SEVERE CONVECTIVE POTENTIAL
THIS AFTERNOON THROUGH TONIGHT. THE MAIN QUESTION IS HOW QUICKLY
CAPPING WILL BE ERODED TO ALLOW FOR SURFACE BASED CONVECTION THIS
AFTERNOON. THE 00 UTC NAM/GFS BUFR SOUNDINGS DO VARY SIGNIFICANTLY
IN REGARDS TO THE STRENGTH OF THIS CAPPING...WITH THE GFS HOLDING
A STRONG CAP THROUGH THE AFTERNOON...WITH THE NAM SHOWING LITTLE
CONVECTIVE INHIBITION BY 18 UTC. THE 03 UTC SREF SOUNDINGS DO SHOW
WEAKER CAPPING THAN THE GFS...HOWEVER...THE 00 UTC 4 KM WRF HAS
LITTLE AFTERNOON CONVECTION ACROSS THE AREA. THUS...DID LIMIT POPS
TO SLIGHT CHANCE OR CHANCE PRIOR TO 00 UTC. SHOULD CAPPING BE
ERODED...ML CAPE VALUES OF 2500-3500 J/KG WITH 50 KTS OF DEEP
LAYER SHEAR ARE AVAILABLE...WITH VERY LARGE HAIL POSSIBLE GIVEN
-10 TO -30 C CAPE VALUES NEAR 1000 J/KG.

THE BETTER CHANCES FOR THUNDERSTORMS ARE THIS EVENING AND TONIGHT
WITH A POTENTIAL MCS PROPAGATING OUT OF SOUTH DAKOTA WITH THE
ARRIVAL OF GREATER UPPER LEVEL FORCING. IN ADDITION TO LARGE HAIL
AND DAMAGING WINDS...HEAVY RAINFALL WILL BECOME AN INCREASING
THREAT...ESPECIALLY FOR THOSE AREAS IMPACTED BY HEAVY RAINFALL
WEDNESDAY AND THURSDAY...WITH PWATS 1.50 INCHES AND K INDEX VALUES
OF 35-40 C.

.LONG TERM...(SATURDAY THROUGH THURSDAY)
ISSUED AT 402 AM CDT FRI JUN 21 2013

THE MAIN FORECAST CONCERNS DURING THE LONG TERM PERIOD ARE THE
POTENTIAL FOR CONTINUED HEAVY RAIN AND FLASH FLOODING OVER THE
WEEKEND. MODEL CONSENSUS INDICATES AN UPPER TROUGH MOVING INTO THE
NORTHERN PLAINS SATURDAY AND SATURDAY NIGHT. BROAD SYNOPTIC LIFT
WILL SUPPORT WIDESPREAD SHOWERS AND THUNDERSTORMS...ESPECIALLY LATER
IN THE DAY. THE JAMES RIVER VALLEY WILL AGAIN BE UNDER THE GUN FOR
ADDITIONAL FLOODING...ALONG WITH ISOLATED SEVERE STORMS. BY
SUNDAY...THE UPPER LOW WILL LIFT NORTH WITH THE FOCUS OF SHOWERS AND
STORMS ACROSS THE NORTHERN COUNTIES...WHICH WILL DIMINISH SUNDAY
NIGHT. SOUTHWEST FLOW WILL PERSIST MONDAY AND TUESDAY WITH RAIN
EXPECTED TO BE MORE SCATTERED ACROSS THE STATE. BY THURSDAY...AN
UPPER RIDGE WILL BEGIN TO SPREAD INTO WESTERN NORTH DAKOTA. CLOUDS
WILL KEEP AFTERNOON TEMPS DOWN MAINLY IN THE 70S OVER THE
WEEKEND...FOLLOWED BY NEAR TO SLIGHTLY ABOVE NORMAL TEMPS IN THE LOW
80S BY EARLY TO MID WEEK.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON)

ISSUED AT 1100 AM CDT FRI JUN 21 2013

PATCHY FOG AND STRATUS WILL CONTINUE ACROSS MUCH OF WESTERN AND
CENTRAL NORTH DAKOTA GIVEN THE HUMID AIRMASS IN PLACE...WITH MVFR
TO IFR CONDITIONS EXPECTED AT TIMES. ISOLATED THUNDERSTORMS ARE
POSSIBLE THIS AFTERNOON...WITH A GREATER CHANCE FOR THUNDERSTORMS
AFTER 22 UTC FRIDAY AFTERNOON MOVING FROM SOUTH TO NORTH THROUGH
FRIDAY EVENING.

&&

.HYDROLOGY...
ISSUED AT 402 AM CDT FRI JUN 21 2013

EXPANDED THE FLASH FLOOD WATCH INTO EMMONS COUNTY GIVEN THE
SIGNIFICANT RAINFALL THAT OCCURRED THURSDAY EVENING. MULTIPLE
ROUNDS OF STRONG TO SEVERE THUNDERSTORMS ARE EXPECTED
FRIDAY THROUGH SUNDAY...WITH ADDITIONAL HEAVY RAINFALL POSSIBLE
FOR THOSE LOCATIONS THAT HAVE SEEN SIGNIFICANT RAINFALL AMOUNTS
WEDNESDAY NIGHT AND THURSDAY EVENING ACROSS SOUTH CENTRAL NORTH
DAKOTA AND THE JAMES RIVER VALLEY. SOILS HAVE LITTLE TO NO
CAPACITY TO HOLD ADDITIONAL WATER...ENHANCING RUNOFF AND THE
POTENTIAL TO AGGRAVATE THE ONGOING OVERLAND FLOODING ACROSS THE
AREA. A COMPLEX OF THUNDERSTORMS WITH HEAVY RAINFALL IS EXPECTED
FRIDAY EVENING AND NIGHT...AND AGAIN SATURDAY NIGHT INTO SUNDAY.
ADDITIONAL RAINFALL AMOUNTS OF 1 TO 3 INCHES ARE POSSIBLE WITH
LOCALLY HIGHER AMOUNTS.
