1150 PM CDT SAT JUN 6 2015

.UPDATE...
ISSUED AT 932 PM CDT SAT JUN 6 2015

THE STORM PREDICTION CENTER DAY ONE OUTLOOK UPDATE HAS EXTENDED
THE SLIGHT RISK FARTHER EAST TO INCLUDE ALL OF NORTHEAST IOWA AND
PORTIONS OF SOUTHEAST MINNESOTA ALONG AND SOUTH OF A LINE FROM
DODGE CENTER TO PRESTON. REASON BEING IS A DEVELOPING MCS ACROSS
NORTHEAST NE/NORTHWEST IA/SOUTHEAST SD THAT IS EXPECTED TO MOVE
EAST-SOUTHEASTWARD OVERNIGHT. PRIMARY THREATS WILL BE HEAVY RAIN
AND GUSTY WINDS...SOME OF WHICH MAY BECOME SEVERE AND PRODUCE
ISOLATED DAMAGE. WITH PWATS INCREASING TO 2.0 INCHES ALONG 40 TO
50 KT 850 HPA JET...WILL NEED TO WATCH FOR POTENTIAL HYDROLOGIC
ISSUES...BUT THINK FORWARD PROPAGATION WILL BE FAST ENOUGH TO
LIMIT FLOODING. UPDATED HWO/WEATHER STORY/FORECAST GRIDS TO
REFLECT THIS THINKING.

&&

.SHORT TERM...(TONIGHT THROUGH SUNDAY NIGHT)
ISSUED AT 305 PM CDT SAT JUN 6 2015

MAIN FORECAST CONCERNS THIS PERIOD...SHRA/TSRA CHANCES WITH FRONTAL
APPROACH/PASSAGE TONIGHT INTO SUN MORNING...TEMPERATURES.

DATA ANALYSIS AT 18Z HAD HIGH PRESSURE OVER THE GREAT LAKES AND A
BROAD TROUGH OF LOW PRESSURE THRU THE CENTRAL/NORTHERN PLAINS. EAST
SOUTHEAST FLOW OUT OF THE HIGH BRINGING A RATHER COMFORTABLE AND
PARTLY TO MOSTLY SUNNY DAY TO WI AND NEARBY AREAS. MOISTURE AXIS WAS
LOCATED FROM MO INTO THE EASTERN DAKOTAS AHEAD OF THE PLAINS LOW.
CONVECTION SO FAR TODAY GENERALLY LIMITED TO THE WEST HALF OF THE
REGION...CLOSER TO/IN THE MOISTURE PLUME AND SOME CONVERGENCE/
FORCING/LIFT AHEAD OF THE PLAINS LOW.

NO PROBLEMS NOTED WITH 06.12Z MODEL INITIALIZATIONS. SOLUTIONS VERY
SIMILAR...AT LEAST AT 500MB...FOR TONIGHT/SUN. THIS AS ENERGY OUT OF
THE WESTERN TROUGH MOVES ACROSS THE SOUTHERN HALF OF THE REGION
TONIGHT/SUN AND THE NORTHERN STREAM ENERGY MOVES ACROSS ND TONIGHT
THEN NORTHERN MN/WI SUN. TREND IS A LITTLE STRONGER WITH THE
SOUTHERN STREAM ENERGY ACROSS IA/NORTHERN IL/SOUTHERN WI TONIGHT/
SUN. TREND FAVORS SLOWER OF EARLIER MODEL RUNS WITH THE NORTHERN
STREAM ENERGY TONIGHT/SUN...RESULTING IN LESS PHASING OF THE 2
PIECES OF ENERGY. TREND IS SLOWER/BIT STRONGER WITH TROUGHING MOVING
ACROSS THE UPPER MIDWEST SUN NIGHT. GIVEN THE OVERALL MODEL
SIMILARITY SHORT TERM FCST CONFIDENCE IS GENERALLY GOOD THIS CYCLE.

FOR THE SHORT TERM...GOOD MODEL AGREEMENT FOR THE SFC TROUGH/FRONT
TO MOVE INTO WESTERN MN THIS EVENING THEN TO NEAR A KDLH-KRST-KOMA
LINE BY 12Z SUN. FRONT THEN MOVES INTO EASTERN WI TO NEAR KDBQ AND
EAST OF KDSM BY 18Z SUN. PLUME OF PW/S IN THE 1.5 TO 2 INCH RANGE TO
SPREAD INTO/ACROSS THE FCST AREA TONIGHT INTO SUN MORNING AHEAD OF
THE SFC-850MB TROUGH/FRONT. EVEN WITH THE INCREASE OF MOISTURE...
CAPE REMAINS RATHER MARGINAL ACROSS THE AREA THRU 12Z SUN. SOME CAPE
IN THE SOUNDINGS LATE AND MAINLY WEST OF THE MS RIVER...BUT THIS
LIFTING ELEVATED PARCELS FROM 850-700MB. DECENT ROUND OF LOWER LEVEL
THERMO-DYNAMIC FORCING/LIFT TO ACCOMPANY THE FRONT INTO/ACROSS THE
AREA TONIGHT...ALONG WITH SOME LIFT/DIVERGENCE ALOFT AHEAD OF THE
APPROACHING MID LEVEL TROUGH AND PIECES OF SHORTWAVE ENERGY. THUS...
A ROUND OF CONVECTION EXPECTED TO ACCOMPANY THE FRONT/TROUGH ACROSS
THE AREA...MAINLY LATE THIS EVENING THRU EARLY SUN MORNING. STILL
SOME CONCERN THAT THE AREA MAY BE SPLIT BY THE CONVECTION. ONE MORE
WIDESPREAD AREA OF CONVECTION MAY STAY NORTH OF THE FCST AREA WITH
THE NORTHERN STREAM SHORTWAVE AND MAIN SFC LOW WHILE A CONVECTIVE
COMPLEX DEVELOPS OVER WESTERN IA/EASTERN NEB AND STAY SOUTH OF THE
AREA WITH THE HIGHER CAPE POOL. GIVEN LESS NORTH/SOUTH STREAM
PHASING SHOWN BY THE MODELS...LATEST TREND AMONG MANY OF THE MODELS
INCLUDING THE REGIONAL WRF/HI-RES MODELS IS FOR MORE OF A LINER
SYSTEM TO PRECEDE/ACCOMPANY THE FRONT ACROSS THE AREA TONIGHT. A
LINEAR CONVECTIVE SYSTEM TONIGHT WOULD BE MORE PRONE TO GENERATING
SOME STRONG/GUSTY WINDS AS IT PASSES. SWODY1 WITH A MARGINAL SEVERE
THREAT TONIGHT LOOKS OKAY. PASSAGE OF THE FRONT TAKES THE HIGHER
PW AIRMASS EAST OF THE FCST AREA BY LATE MORNING/ EARLY AFTERNOON...
ALONG WITH THE LOWER LEVEL FORCING/LIFT. PASSAGE OF THE SOUTH
PIECE OF SHORTWAVE ENERGY TAKES THE BULK OF THE UPPER LEVEL FORCING/
LIFT WITH IT AS WELL. MORE CAPE OVER THE AREA ON SUN VS. TONIGHT...
BUT WITH LESS MOISTURE AND ANTICYCLONIC SFC-850MB FLOW BEHIND THE
TROUGH...WILL CONTINUE TO TREND SHRA/TSRA CHANCES DOWN SUN
AFTERNOON AND DRY SUN NIGHT. MINIMAL LOWER LEVEL COLD ADVECTION
BEHIND THE COLD FRONT SUNDAY...WITH 850MB TEMPS SUN AFTERNOON
STILL CAPABLE OF SUPPORTING HIGHS IN THE MID 70S TO LOWER 80S.
USED A BLEND OF THE GUIDANCE LOWS/HIGHS TONIGHT THRU SUN NIGHT.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 305 PM CDT SAT JUN 6 2015

MAIN FCST CONCERNS FOR MON THRU TUE NIGHT...SHRA/TSRA CHANCES
ALONG/NORTHEAST OF I-94 MON AFTERNOON AND AREA WIDE TUE NIGHT...
TEMPERATURES THRU THE PERIOD.

06.12Z MODELS IN GOOD AGREEMENT FOR A SLOWER OVERALL TROUGH PASSAGE
MONDAY...AIDED BY A STRONGER SHORTWAVE TO DROP DOWN THE WESTERN SIDE
OF THE TROUGH ACROSS WI/EASTERN MN MON AFTERNOON. SHORTWAVE QUICKLY
PASSES WITH THE TROUGH MOVING EAST/HGTS RISING OVER THE REGION MON
NIGHT/TUE...AHEAD OF YET ANOTHER MID LEVEL LOW/TROUGH MOVING INTO
ONT TUE NIGHT. TREND IS STRONGER WITH THE TROUGH/LOW NORTH OF THE
REGION TUE NIGHT. FCST CONFIDENCE IN THE MON THRU TUE NIGHT PERIOD
IS AVERAGE TO GOOD THIS CYCLE.

TREND MONDAY IS FOR THE SHORTWAVE DROPPING DOWN THE WEST SIDE OF THE
PASSING TROUGH TO TRACK FURTHER WEST WITH THE EAST HALF OF THE FCST
AREA NOW ON THE CYCLONIC SIDE OF THE 500-300MB JET AXIS. THIS WITH
QUITE STEEP LOW/MID LEVEL LAPSE RATES...PW VALUES AROUND 1 INCH AND
SB/MU CAPE IN THE 500-1000 J/KG RANGE. GIVEN CONSISTENCY OF THE
MODEL SIGNAL...INCREASED/EXPANDED SHRA/TSRA CHANCES LATE MON
MORNING/MON AFTERNOON TO COVER ROUGHLY THE EAST HALF OF THE FCST
AREA. INCREASED WINDS A BIT ON MON AS WELL WITH THE DEEP MIXING/
STEEP SFC-700MB LAPSE RATES. WITH FAST EXIT OF THE SHORTWAVE AND 500-
300MB JET AXIS MOVING EAST OF THE FCST AREA CONTINUED WITH A DRY
FCST MON NIGHT. 850MB THERMAL RIDGE AHEAD OF THE NEXT TROUGH/FRONT
BUILDS OVER THE AREA TUE...WITH SOME CAPPING AT/ABOVE 800MB. TUE
STILL LOOKING LIKE THE WARMEST DAY OF THE SEASON SO FAR...WITH 850MB
TEMPS TUE AFTERNOON IN THE +17C TO +21C RANGE. THIS WOULD SUPPORT
HIGHS IN THE MID 80S TO AROUND 90 ACROSS MUCH OF THE FCST AREA. DID
RAISE HIGHS TOWARD WARMER OF GUIDANCE ON TUE. IF AREA GETS LESS RAIN
THAN EXPECTED TONIGHT/EARLY SUN AND THE LANDSCAPE IS A LITTLE
DRIER...SOME HIGHS OF 90F TO 92F CERTAINLY POSSIBLE TUE AFTERNOON...
ESPECIALLY IN THE MS/WI RIVER VALLEYS. NEXT LOW/TROUGH INTO ONT TUE
NIGHT DRIVE A COLD FRONT SOUTH/EAST ACROSS THE FCST AREA. TREND IS A
BIT STRONGER ON THE LOWER LEVEL FORCING/LIFT WITH THE SFC-850MB
TROUGH. THIS WITH SOME MUCAPE AND PW VALUES OF 1 TO 1.4 INCHES AHEAD
OF THE FRONT. 20-30 PERCENT SHRA/TSRA CHANCES...MAINLY AFTER
MIDNIGHT TUE NIGHT... REASONABLE FOR NOW. USED A BLEND OF THE
GUIDANCE HIGHS/LOWS FOR MON AND MON/TUE NIGHTS.

FOR WEDNESDAY THROUGH SATURDAY...DAYS 4 TO 7...

MAIN FCST CONCERNS THIS PERIOD...SHRA/TSRA CHANCES AND TEMPERATURES
THRU THE PERIOD.

MEDIUM RANGE MODEL RUNS OF 06.00Z/06.12Z IN GOOD AGREEMENT FOR QUASI-
ZONAL FLOW ACROSS THE NORTHERN CONUS WED...WITH ONE BROAD TROUGH
PASSING ACROSS ONT/GREAT LAKES AND ANOTHER CROSSING THE NORTHERN
ROCKIES. REASONABLE AGREEMENT AT LEAST AMONG GFS/ECMWF FOR THE
NORTHERN ROCKIES TROUGH TO MOVE INTO THE NORTHERN PLAINS THU. MODELS
AT ODDS WITH THE DETAILS OF THE FLOW EVOLUTION BY FRI AND FOR SAT
WHICH ALSO MAKES FOR RATHER POOR RUN-TO-RUN CONSISTENCY IN THE DAY
6/7 TIMEFRAME. HOWEVER...SOME LARGER SCALE CONSENSUS FOR TROUGHING
OVER THE CENTRAL CONUS INTO UPPER MIDWEST FRI/SAT...FOR WHAT WOULD
BE A MORE UNSETTLED PERIOD. FCST CONFIDENCE AVERAGE WED/THU THEN
BELOW AVERAGE FRI/SAT.

MID LEVEL TROUGH/LOW TRACKING ACROSS ONT WED CONTINUES TO PUSH THE
TUE NIGHT FRONT SOUTH/EAST OF THE FCST AREA ON WED. PERHAPS A SMALL
-SHRA/TSRA CHANCE ACROSS THE SOUTHEAST END OF THE FCST AREA WED
MORNING. OTHERWISE...IF THE TIMING OF THE FRONT HOLDS WED TRENDS DRY
AS WEAK CAN HIGH PRESSURE/SHORTWAVE RIDGING BUILDS OVER THE REGION.
REASONABLE CONSENSUS FOR THE FRONT TO STALL SOMEWHERE NEAR I-80...
THEN ALREADY START TO RETURN NORTH WED NIGHT AS LEE TROUGHING/
SOUTHERLY FLOW STRENGTHENS IN THE CENTRAL/NORTHERN PLAINS. FRONT
WOULD BE THE FOCUS FOR CONVERGENCE/LIFT AS THE MOIST/UNSTABLE
AIRMASS IS PUSHED NORTHWARD OVER IT. WITH THE FRONT SOUTH OF THE
AREA WED NIGHT/THU...SOME SHRA/TSRA CHANCES THESE PERIODS REASONABLE
UNTIL THE DETAILS BECOME CLEARER. MID LEVEL TROUGHING MOVING ACROSS
THE CENTRAL/NORTHERN PLAINS TOWARD/INTO THE REGION FRI/SAT WOULD
LIFT THE FRONT NORTHWARD AND SEND A WAVE OF LOW PRESSURE NORTHEAST
ALONG IT. THIS WITH WHAT SHOULD BE AN UNSTABLE AND VERY MOIST
AIRMASS SOUTH OF THE FRONT. SHRA/TSRA CHANCES IN THE 40-60 PERCENT
RANGE FOR THE THU NIGH THRU FRI NIGHT PERIOD OKAY FOR NOW. TEMPS
TRENDING ABOVE NORMAL WED/THU...THEN NEAR NORMAL FRI/SAT WITH WHAT
LOOKS TO BE MORE CLOUD COVER AS THE LOW WOULD TRACK ACROSS THE
REGION. CONSENSUS OF GUIDANCE HIGHS/LOWS FOR WED-SAT LOOKS GOOD.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SUNDAY NIGHT)
ISSUED AT 1150 PM CDT SAT JUN 6 2015

AN AREA OF SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE UPPER
MISSISSIPPI RIVER VALLEY OVERNIGHT INTO EARLY SUNDAY MORNING AS
A COLD FRONT SWEEPS ACROSS THE REGION. VFR CONDITIONS WILL
POTENTIALLY GIVE WAY TO IFR CEILINGS AND VISIBILITY RESTRICTIONS
AS LOW AS 1 SM WITH THE STRONGEST THUNDERSTORMS. AS THERE WILL BE
BREAKS BETWEEN THUNDERSTORMS...WILL COVER THIS THREAT WITH TEMPO
GROUPS. PRECIPITATION IS EXPECTED TO MOVE EAST OF KRST/KLSE IN THE
07.11 TO 07.13Z TIME FRAME. MODERATE SOUTHERLY WINDS WILL PERSIST
OVERNIGHT...ALTHOUGH THERE COULD BE BRIEF STRONGER ERRATIC WINDS
WITH ANY THUNDERSTORMS. EXPECT WINDS TO SHIFT TO THE SOUTHWEST
SUNDAY MORNING AND THEN TO THE NORTHWEST AFTER COLD FRONTAL
PASSAGE.
