AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
348 PM CDT SUN JUL 31 2011

.DISCUSSION...

SUMMARY...MOST ACTIVE WEATHER THIS WEEK MAY WELL BE WITHIN THE
NEXT 24-36 HOURS WITH THE FRONTAL BOUNDARY DRAPED ACROSS THE
AREA. A COUPLE ROUNDS OF STRONG THUNDERSTORMS SEEM POSSIBLE
TONIGHT AND TOMORROW ACROSS THE REGION. THERE ARE SOME QUESTIONS
AS TO THE AMOUNT OF COVERAGE TONIGHT...AND THE MOST WIDESPREAD
CONVECTION MAY BE ACROSS NORTHERN MN TOMORROW. WE SHOULD GET A
BOUT OF QUIETER WEATHER AND COOLER TEMPS AND DEW POINTS AFTER THE
BOUNDARY PUSHES SOUTH TUESDAY NIGHT. A HEAT ADVISORY WILL BE
NEEDED IN SOUTH CENTRAL/SOUTHWEST MN TO MATCH UP WITH DMX/FSD.

NEARLY STATIONARY BOUNDARY STRETCHING ACROSS SOUTH/CENTRAL MN AND
WEST CENTRAL WI. THE SAME BOUNDARY IS LIFTING NORTH AS A WARM
FRONT ACROSS THE DAKOTAS...WHERE A FEW ECHOES ROOTED ABOVE THE
BOUNDARY LAYER HAVE DEVELOPED THIS AFTERNOON.
THERMODYNAMICALLY...TIGHT INSTABILITY GRADIENT ALONG THE FRONT
WITH A POOL OF 3000-5000 J/KG OF SBCAPE AND MLCAPE SOUTH OF THE
BOUNDARY ACROSS SOUTHERN MN. BOUNDARY LAYER INSTABILITY HAS GROWN
STEADILY AS WELL THIS AFTERNOON WITH 100-200 J/KG IN THE 0-3KM
LAYER. TOWERING CUMULUS HAVE BEEN APPARENT ON SATELLITE SINCE
EARLY THIS AFTERNOON...BUT SO FAR DEEP MOIST CONVECTION HAS NOT
OCCURRED. HARD TO BELIEVE WE WILL NOT SEE SOME DEEP MOIST
CONVECTION ALONG THIS BOUNDARY BEFORE 6-7 PM CDT. LOCAL 4KM WRF-
ARW AND HRRR BOTH DEVELOP SCATTERED THUNDERSTORMS ON THE SOUTH
SIDE OF THIS BOUNDARY AND TRACK THE STORMS SOUTHEAST THIS EVENING
BEFORE GRADUALLY DIMINISHING. THE HEIGHTENED RISK FOR SEVERE FROM
SPC TONIGHT IS IN THE DAKOTAS AND FAR WESTERN NEAR THE WARM
FRONT...WHERE DEEP LAYER SHEAR IS MORE SUPPORTIVE OF ORGANIZED
CONVECTION...INCLUDING SUPERCELLS. AS OF RIGHT NOW...MOISTURE
CONVERGENCE ALONG THE BOUNDARY HAS NOT BEEN GREAT...BUT STILL
APPARENT. GIVEN THE GOOD INSTABILITY AND FAIR 850-500MB FLOW...ANY
STORMS IN SOUTHERN MN/WESTERN WI WOULD HAVE TO BE MONITORED FOR
SEVERE POTENTIAL. THE OVERALL COVERAGE MAY BE SOMEWHAT LIMITED
UNLESS THUNDERSTORM OUTFLOW CAN LEAD TO CONVECTIVE INITIATION.

NEXT...OUR ATTENTION TURNS TO THE NICE SHORTWAVE/VORTICITY MAX IN
EASTERN MT THIS AFTERNOON. THIS SHOULD ROUND THE RIDGE AS HEIGHTS
BUILD IN ACROSS MN/WI TONIGHT. WE MAY END UP WITH ONE OR TWO
COMPLEXES OF STORMS TRACKING OUT OF NORTH DAKOTA AND INTO NORTHERN
MN. IN THE MPX CWA...THE MOST FAVORABLE AREAS TO SEE THIS ACTIVITY
MONDAY/MONDAY EVENING WILL BE FROM MORRIS...TO ST. CLOUD...TO RICE
LAKE. HEAVY RAIN COULD BE A THREAT WITH THE STORMS...PWATS CREEP
UP TOWARD 1.75" IN CENTRAL MN BY TOMORROW AFTERNOON.

SHOULD BE A REPRIEVE FROM THE THUNDERSTORM CHANCES TUESDAY NIGHT
THROUGH THURSDAY MORNING WITH SURFACE RIDGE OVERHEAD. WILL HAVE TO
MONITOR A COUPLE CIRCULATIONS SHOWING UP IN WATER VAPOR TODAY IN
SW COLORADO AND SOUTHERN CALIFORNIA...WHICH THE STEERING WINDS
SHOULD ADVECT INTO THE MID-UPPER MISSISSIPPI RIVER VALLEY. THE
EXTENDED IS A LITTLE MESSY WITH A LOT OF SLIGHT CHANCE POPS...AND
SEVERAL EMBEDDED SHORTWAVES IN THE GENERALLY WEST-EAST ORIENTATED
FLOW. NEARLY IMPOSSIBLE TO TRUST THE POSITION AND TIMING OF THESE
WAVES FOR THE WEEKEND. SO...AT THIS POINT POPS REALLY ARE NOT ALL
THAT DIFFERENT FROM CLIMO.

&&

.AVIATION.../18Z TAF ISSUANCE/

FORECAST A BIT TRICKY THIS AFTERNOON IN TERMS OF THUNDER CHANCES.
A FRONTAL EXTENDS ACROSS SOUTHERN MN INTO NORTHEAST SOUTH DAKOTA.
VERY UNSTABLE CONDITIONS ACROSS THIS AREA...BUT FORCING
MECHANISMS ON THE WEAK SIDE IN TERMS OF LOW LEVEL FLOW TO ACT AS A
TRIGGER. IF STORMS FORM THEY WOULD LIKELY BE STRONG TO SEVERE. THE
GREATEST RISK APPEARS TO BE OVER SOUTH CENTRAL AND SOUTHEAST MN
INTO WISCONSIN. KMSP COULD AND KEAU COULD BE AFFECTED. HAVE
KEPT THE MENTION OF VCNTY THUNDER ON THOSE LOCATIONS BUT WILL NEED
TO WATCH THE TRENDS N THE NEXT HOUR OR TWO FOR UPDATES TO LOWER
CONDITIONS IN THUNDERSTORMS. OTHERWISE LOW END VFR CIGS TO SOME
LINGERING MVFR FORM KMSP TO KEAU FOR THE AFTERNOON. WITH SCT
CONDITIONS AT KSTC. THE THUNDER THREAT WILL LIKELY PERSIST INTO THE
EARLY EVENING...THEN ATTENTION TURNS TO THE CENTRAL DAKOTAS WHERE
MORE STORMS SHOULD FORM TONIGHT AND EXPAND INTO WEST CENTRAL MN
MONDAY MORNING. HAVE INCLUDE THUNDER AT KSTC AND KAXN FOR THIS
POSSIBILITY. THERE MAY ALSO BE RISK OF IFR VSBY IN FOG FROM KRNH
TO KEAU EARLY WEDNESDAY MORNING. LIGHT AND VARIABLE WIND CONDITIONS
NORTH OF KRWF BUT EXPECT A GRADUAL SHIFT TO A 130-180 DIRECTION
OVERNIGHT.

KMSP...MVFR CIGS LIFTING TO LOW END VFR IN CUMULUS IN THE NEXT
HOUR OR TWO. HAVE INCLUDED THE VCNTY THUNDER FROM 21Z TO ABOUT
02Z BUT WILL NEED TO WATCH THE TRENDS. THERE IS A LOW RISK OF
THUNDER REACHING THE FIELD LATER MONDAY MORNING BUT CURRENT
THINKING TI THAT ACTIVITY WILL REMAIN TO THE NORTH. LIGHT AND
VARIABLE WIND CONDITION THIS AFTERNOON AND EVENING WITH THE HIGH
PRESSURE OVERHEAD...BUT A GRADUAL TREND TO 130-180 LATE TONIGHT
AND MONDAY MORNING.
