What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Aberdeen, SD wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 29, 9:19 AM CDT, 45 minutes earlier.

Area forecast discussion, Jun 29, 9:19 AM CDT, 45 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ABERDEEN SD
919 AM CDT FRI JUN 29 2012

.UPDATE...
NO CHANGES PLANNED TO THE MAX TEMPERATURE FORECAST TODAY. MORNING
WARM UP WILL BE HAMPERED FOR A FEW HOURS DUE TO CONVECTIVE
CLOUDINESS AND RAINFALL...PARTICULARLY ACROSS THE WESTERN AND
CENTRAL TWO-THIRDS OF THE CWA. UPDATED WX/POP/QPF GRIDS TO TRY AND
BETTER TIME THE ONGOING BATCH OF SHOWERS AND THUNDERSTORMS WORKING
THROUGH THE WESTERN FORECAST ZONES. WILL MAKE ADDITIONAL UPDATES
TO THE WX/POP GRIDS AS NEEDED TODAY. UPDATES ARE OUT.

&&
.PREVIOUS DISCUSSION...
.SHORT TERM...TODAY THROUGH SUNDAY
LOW LEVEL MOISTURE IS BEGINNING TO RETURN TO THE REGION AS A PLUME
OF HIGHER DEWPOINTS IS CREEPING NORTHWEST INTO THE AREA. DEWPOINTS
ARE CURRENTLY IN THE 70S ACROSS CENTRAL AND EASTERN NEBRASKA.
THERE IS A NOTABLE SHORTWAVE TRACKING EAST ACROSS SOUTHEAST
MONTANA AND ABOUT READY TO ENTER THE DAKOTAS. SFC BOUNDARY ALSO
LAYED UP ACROSS THE SOUTH DAKOTA/NEBRASKA BORDER. ALONG THIS
SURFACE BOUNDARY...THUNDERSTORMS HAVE DEVELOPED OVER THE PAST
HOUR. THUS FAR THEY HAVE REMAINED ACROSS SOUTH CENTRAL SOUTH
DAKOTA IN UNR CWA BUT EARLY SIGNS OF ADDITIONAL DEVELOPMENT ACROSS
THE SOUTHWEST CWA ON RADAR AND SATELLITE IMAGERY.

CONVECTIVE TRENDS TODAY AND TOMORROW RATHER DIFFICULT TO NAIL DOWN
AND FORECASTER CONFIDENCE IS FAIRLY LOW IN PINPOINTING EXACT
TIMING AND PLACEMENT OF ANY STORMS. IT DOES APPEAR THERE COULD BE
ADDITIONAL DEVELOPMENT LATER THIS MORNING AS AFOREMENTIONED
SHORTWAVE ROLLS THROUGH THE AREA. THERE WILL BE ENOUGH INSTABILITY
TO TAP INTO AS WELL AS SHEAR. 06Z NAM SUGGESTING ADDITIONAL
DEVELOPMENT LATER THIS MORNING ACROSS NORTH CENTRAL SD AS THE MAIN
SHORTWAVE ENERGY MOVES IN. EVIDENCE OF THIS ALREADY WITH SHOWERS
AND A FEW STORMS ACROSS SOUTHEAST MONTANA. PAST FEW RUNS OF THE
HRRR ALSO SHOWING A CLUSTER OF SHOWERS AND STORMS ROLLING EAST
ACROSS NORTHERN SOUTH DAKOTA AND SOUTHERN NORTH DAKOTA THROUGH THE
MORNING ASSOCIATED WITH THE SHORTWAVE ENERGY. HAVE INCREASED POPS
FOR THE MORNING HOURS.

CONVECTION POSSIBLE ON SATURDAY AS WELL...BUT ONCE AGAIN A
DIFFICULT FORECAST TO NAIL DOWN. WILL HAVE INSTABILITY AND SHEAR
PRESENT ONCE AGAIN...BUT IT DOES NOT APPEAR THERE WILL BE A
NOTEWORTHY WAVE AS COMPARED TO TODAY. A SFC COLD FRONT WILL BE
DROPPING SOUTHEAST THROUGH THE DAKOTAS AND IT WILL PROBABLY HAVE
TO BE THIS SURFACE CONVERGENCE THAT WILL HAVE TO GET STORMS GOING.
MODELS ARE STILL HAVING A TOUGH TIME DETERMINING JUST HOW FAR
SOUTHEAST IT REACHES BY 00Z SUNDAY. THIS WILL HAVE A HUGE EFFECT
ON POPS.

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY
AN UPPER LEVEL RIDGE WILL REMAIN OVER THE REGION THROUGH THE
ENTIRE EXTENDED PERIOD...WITH JUST A COUPLE OF SHORT PERIODS OF
THE RIDGE GETTING DAMPENED A BIT BY A PASSING SHORTWAVE. CURRENTLY
LOOKS AS THOUGH THIS WILL HAPPEN MONDAY NIGHT...TUESDAY
NIGHT...AND TOWARD THE VERY END OF THE PERIOD. A SURFACE FRONTAL
BOUNDARY WILL ACCOMPANY THE FIRST WAVE...AND LOOKS TO BRING A
CHANCE OF PRECIPITATION MONDAY AFTERNOON AND MONDAY NIGHT. ANOTHER
FRONTAL BOUNDARY APPROACHES ON TUESDAY...WITH ANOTHER CHANCE OF
PRECIPITATION TUESDAY NIGHT. THE MODELS THEN DIVERGE SOME TOWARD
THE LATTER PART OF THE PERIOD...SO HAVE GENERALLY STUCK CLOSE TO
THE ALLBLEND SOLUTION. WILL KEEP ALL OF THE PRECIPITATION MENTION
AS THUNDERSTORMS AS DECENT INSTABILITY DEVELOPS WITH EACH BOUNDARY
AND WAVE. HOWEVER...WILL KEEP POPS IN THE SLIGHT CHANCE TO LOW
CHANCE CATEGORIES AS IT DOES APPEAR THERE WILL BE A DECENT CAP IN
PLACE IN ASSOCIATION WITH THE STRONG UPPER RIDGE.

TEMPERATURES WILL CONTINUE TO BE ABOVE NORMAL UNDER THE UPPER
LEVEL RIDGE...WITH H85 TEMPERATURES IN THE MID TO UPPER 20S
CELSIUS. THIS SHOULD RESULT IN SURFACE TEMPERATURES IN THE 90S
DURING THE AFTERNOON HOURS...WITH OVERNIGHT LOWS MAINLY IN THE
LOWER TO MID 70S.

&&

.AVIATION...
12Z TAFS FOR THE KABR...KATY...KPIR AND KMBG TERMINALS

SHOWERS AND THUNDERSTORMS WILL SPREAD FROM WEST TO EAST ACROSS THE
AREA DURING THE MORNING AND EARLY TO MID AFTERNOON HOURS. AT THIS
TIME...IT DOES NOT APPEAR THAT THE STORMS WILL BE SEVERE...BUT
LIGHTNING AND BRIEF GUSTY WINDS ARE POSSIBLE. CIGS AND VSBYS
SHOULD REMAIN VFR...WITH THE PRECIPITATION EXPECTED TO EXIT THE
EASTERN CWA BY LATE AFTERNOON. VFR CONDITIONS WILL THEN PREVAIL
THROUGH THE NIGHTTIME HOURS.
