AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
402 PM CDT SAT JUN 14 2014

.SHORT TERM...(THIS EVENING THROUGH SUNDAY)
ISSUED AT 305 PM CDT SAT JUN 14 2014

CONCERN NEAR TERM IS SEVERE WEATHER/HYDRO THREAT THROUGH THE
NIGHT.

STRONG WINDS ASSOCIATED WITH COMPLEX TO THE SOUTHWEST AND
AREA OF RAIN OVER THE METRO IS LIFTING TO THE NORTHEAST AND
WEAKENING. WILL LIKELY MAINTAIN SOME GUSTY WINDS INTO THE EVENING
AS GRADIENT REMAINS EAST OF THE DEVELOPING LOW PRESSURE.

SEVERE WEATHER THREAT REMAINS INTO THE EVENING MAINLY TO THE
SOUTHWEST...AS ACTIVITY ALONG THE FRONT OVER THE DAKOTAS MOVES
EAST. MAIN THREAT IS HEAVY RAIN DURING THE NIGHT AS THE STRONG
UPPER TROUGH MOVES THROUGH. LOOKS FORM WIDESPREAD 1-2 INCHES OF
RAIN ACROSS CENTRAL MN INTO WEST CENTRAL WISCONSIN WITH PERHAPS
LOCALIZED AMOUNTS 3-4 INCHES. THIS WOULD AFFECT SOUTH CENTRAL MN
INTO EAST CENTRAL MN. STRONG MOISTURE TRANSPORT LIFTS NORTH OVER
THE AREA AS UPPER TROUGH LIFTS NORTHEAST LATER TONIGHT/SUNDAY
MORNING. 150%-180% ABOVE NORMAL PRECIPITATELY WATER LIFTS ACROSS
THE REGION ALONG WITH SIGNIFICANT FORCING. IT WILL BE RELATIVELY
FAST MOVING...BUT PRECIPITATION RATES WILL BE EXTREME.  FLASH
FLOOD WATCH ISSUED FOR THE EVENT TONIGHT INTO SUNDAY MORNING.

THE RAIN IS FORECAST TO LIFT NORTHEAST DURING THE MORNING AND EXIT
THE FAR EASTERN AREA INTO THE AFTERNOON. SHOULD SEE ANY SIGNIFICANT
SEVERE THREAT DEVELOP EAST OF THE CWA INTO SUNDAY AFTERNOON.

.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 402 PM CDT SAT JUN 14 2014

THE LONG TERM LOOKS VERY WET WITH A GOOD POTENTIAL OF RIVER/LOW
LAND FLOODING AT SOME POINT AS WE HEAD INTO LATE NEXT WEEK.
INITIALLY SUNDAY EVENING HIGH PRESSURE WILL BE LOCATED OVER THE
OHIO VALLEY. SOMEWHAT DRIER AIR FROM THIS HIGH WILL BE ENTRAINED
IN THE SOUTHERLY FLOW SUNDAY NIGHT AND MONDAY MORNING...SO NOT
ANTICIPATING MUCH OF A CHANCE OF RAIN. IN FACT...SUNDAY NIGHT WILL
BE MOSTLY CLEAR SO FINALLY A BREAK FROM THE RAIN.

BY MONDAY AFTERNOON...ANOTHER WAVE WILL EJECT FROM THE TROUGH IN
THE PACIFIC NORTHWEST AND ROUND THE TOP OF A BUILDING RIDGE OVER
THE SOUTHEASTERN CONUS. THIS WILL BEING INCREASING CHANCES FOR
THUNDERSTORMS ACROSS WESTERN MINNESOTA WHICH ARE EXPECTED TO
EXPAND IN COVERAGE...POSSIBLY INTO A MCS AS IT TRACKS EASTWARD
INTO ERN MN AND WRN WI MONDAY NIGHT. MAINTAINED VERY HIGH POPS
MONDAY NIGHT.

THE MCS SHOULD BE WELL TO THE EAST BY EARLY MORNING TUESDAY AND
TUESDAY LOOKS DRY AS RIDGING BUCKLES NORTHWARD INTO THE UPPER
MIDWEST. WARMER AND MORE HUMID CONDITIONS WILL ARRIVE AS 925 MB
TEMPS REACH +23 TO +24C /85-90F AT THE SURFACE/ AND DEW POINTS
CREEP UPWARD INTO THE LOWER 70S.

MID LEVEL RIDGING CONTINUES TO BUILD TUESDAY NIGHT INTO WEDNESDAY.
THIS SHOULD LARGELY PREVENT ANY LARGE THUNDERSTORM COMPLEXES FROM
TRESPASSING INTO THE AREA...HOWEVER THE ATMOSPHERE WILL BE QUITE
UNSTABLE AND IT WOULD NOT TAKE MUCH TO GENERATE SCATTERED SHOWERS
AND STORMS...ESPECIALLY ON WEDNESDAY AFTERNOON AS TEMPERATURES
RETURN INTO THE 80S AND POSSIBLY NEAR 90 ACROSS SRN MN.

BY WEDNESDAY NIGHT THE WESTERN TROUGH WILL ADVANCE EAST INTO THE
NORTHERN PLAINS. MID LEVEL HEIGHT FALLS AND NUMEROUS DISTURBANCES
BEING KICKED OUT FROM THE TROUGH WILL BRING SEVERAL ROUNDS OF
SHOWERS AND THUNDERSTORMS THROUGH THURSDAY NIGHT. A FEW INCHES OF
RAIN ARE POSSIBLE DURING THIS PERIOD.

BY FRIDAY...THE CUT OFF LOW PRESSURE CENTER SHOULD BE SOMEWHERE
OVER THE UPPER MIDWEST. THIS WILL REDUCE THE THREAT FOR HEAVY
RAIN MCS DEVELOPMENT...BUT ROUNDS OF SHOWERS AND STORMS ARE STILL
POSSIBLE INTO EARLY NEXT WEEKEND WITH THE LOW SLOWLY HEADED EAST
INTO THE GREAT LAKES. IT LOOKS A BIT COOLER AS WELL WITH HIGHS
RETREATING BACK INTO THE MID 70S.

WPC IS STILL ADVERTISING A GOOD 5-7 INCHES THROUGHOUT THE NEXT 7
DAYS. WHILE THIS WILL BE SPREAD OUT A BIT TEMPORALLY...SIGNIFICANT
RISES IN RIVERS AND LAKES ARE LIKELY AS WE HEAD THROUGH NEXT WEEK.
