Weekend severe weather (derechos?) - August 8-9
The SPC has some pretty strong wording on their advisories across the Northern Plains and Great Lakes for this weekend. I wouldn't be surprised at all to see them turn into intense bow echoes/derechos. They already considered a moderate risk for tomorrow.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0759 AM CDT SAT AUG 08 2009
VALID 081300Z - 091200Z
...THERE IS A SLGT RISK OF SVR TSTMS FROM THE DAKOTAS INTO THE UPR
MS VLY/GRT LKS...
...SYNOPSIS...
GRT BASIN/NRN RCKYS UPR TROUGH WILL SHEAR ENE ACROSS THE NRN PLNS
AND UPR MS VLY THIS PERIOD AS SERN U.S. RDG BUILDS N INTO THE OH
VLY. IN RESPONSE...A BELT OF MODERATE SW TO WSWLY MID LVL FLOW...
WITH NUMEROUS EMBEDDED SPEED MAXIMA...WILL PREVAIL FROM THE
CNTRL/SRN RCKYS ACROSS THE NRN/CNTRL PLNS TO THE UPR MS VLY/GRT LKS.
ON THE SRN FLANK OF THE SE U.S. RDG...A DISTURBANCE NOW NEAR NEW
ORLEANS SHOULD CONTINUE WNW ACROSS LA TODAY AND REACH THE ARKLATEX
EARLY SUN.
AT THE SFC...NRN PART OF COMPLEX/ELONGATED NOW OVER NEB EXPECTED TO
REDEVELOP NEWD INTO SW MN/NW IA LATER TODAY...BEFORE CONTINUING ENE
INTO WI EARLY SUN. TRAILING SRN PART OF LOW SHOULD SETTLE SLOWLY S
INTO NRN/WRN KS. AS NRN PART OF LOW APPROACHES MN...WARM SECTOR
WILL EXPAND FARTHER NE FROM THE CORN BELT INTO THE SRN GRTLKS. W OF
THE LOW...SEVERAL WEAK COLD FRONTAL SURGES WILL REINFORCE LOW LVL
NLY FLOW ALREADY IN PLACE FROM THE DAKOTAS SW INTO THE CNTRL HI
PLNS.
...DAKOTAS/UPR MS VLY TO GRTLKS...
SCTD ELEVATED TSTM CLUSTERS NOW OVER ERN SD...THE UPR MS VLY AND UPR
GRT LKS SHOULD MOVE/DEVELOP GENERALLY ESE ACROSS THE LWR GRT LKS
LATER TODAY IN ASSOCIATION WITH ZONE OF ELEVATED MOISTURE
TRANSPORT/WAA. THE STORMS SHOULD WEAKEN AS THE STRONGEST ELEVATED
INSTABILITY LIKELY WILL REMAIN FARTHER W ACROSS MN/WI.
NOSE OF WARM MID TROPOSPHERIC TEMPERATURES /10-12 C AT 700 MB/ NOW
OVER PLNS AND PARTS OF THE UPR MS VLY WILL CONTINUE TO SPREAD ENE
ACROSS THE UPR MS VLY IN WAKE OF MORNING STORM CLUSTERS. RICH
BOUNDARY LAYER MOISTURE WILL PERSIST BENEATH THE WARM LAYER...WITH
LOW 70S F DEW POINTS AND PW AOA 2 INCHES OVER IA AND ADJACENT PARTS
OF MN/WI AND IL. LOW LVL MOISTURE ALSO WILL LINGER N AND W OF NEB
SFC LOW OVER THE ERN DAKOTAS AND NRN/CNTRL NEB.
A SERIES OF WEAK DISTURBANCES WILL TRACK NEWD FROM THE CNTRL HI PLNS
TO THE ERN DAKOTAS/UPR MS VLY TODAY AND TONIGHT. INCREASING ASCENT
WITH THESE IMPULSES LIKELY WILL SUPPORT ADDITIONAL POST-FRONTAL
STORMS TODAY OVER THE WRN DAKOTAS. COMBINATION OF STEEP MID LVL
LAPSE RATES AND MODEST CLOUD LAYER SHEAR SUGGESTS THAT SOME OF THE
STORMS MAY YIELD HAIL.
MORE SUBSTANTIAL STORM DEVELOPMENT SHOULD OCCUR THIS AFTN OVER
CNTRL/ERN SD...AND THIS EVE OVER CNTRL/SRN MN...IN RESPONSE TO /1/
DIURNAL HEATING AND /2/ GRADUAL INCREASE IN UPR LVL COOLING/ASCENT
WITH APPROACH OF MAIN UPR TROUGH. THE STORMS SHOULD CONCENTRATE N
AND E OF SFC LOW WHERE STRONG INSTABILITY /SBCAPE TO 3500 J PER KG/
WILL EXIST IN THE PRESENCE OF 45-50 KT DEEP WSWLY SHEAR. SETUP
APPEARS FAVORABLE FOR SUPERCELLS WITH VERY LARGE HAIL AND POSSIBLY
TORNADOES.
PERSISTENT WSWLY FEED OF MOIST/UNSTABLE AIR AND W TO WNWLY MEAN FLOW
LIKELY WILL SUPPORT THE DEVELOPMENT OF A SERIES OF CONVECTIVE
CLUSTERS EXTENDING FROM MN/WI ESE INTO PA/NY BY LATER TONIGHT/ EARLY
SUN. EMBEDDED STORMS WITHIN THESE SYSTEMS MAY CONTINUE TO POSE A
RISK FOR ISOLD SVR HAIL. LOCALLY DMGG WIND WILL ALSO BE POSSIBLE
WITH THE MORE WRN/SRN CLUSTERS.
A SEPARATE AREA OF ORGANIZED SVR STORMS MAY ALSO EVOLVE OVER
PARTS OF NRN SD AND CNTRL/ERN ND INVOF INVERTED TROUGH/COLD FRONT.
THERE...COMPARATIVELY COOLER MID LVL TEMPERATURES EDGING E WITH
MAIN UPR TROUGH WILL WEAKEN CAP. WEAK CONVERGENCE ALONG THE
TROUGH...COUPLED WITH SBCAPE AROUND 1000 J/KG AND 40+ KT DEEP WSWLY
SHEAR MAY YIELD A FEW SUSTAINED STORMS CAPABLE OF SVR
HAIL...DMGG WINDS...AND PERHAPS A BRIEF TORNADO.
...LWR MS VLY...
UPR LVL WAVE MOVING WNW ACROSS THE CNTRL GULF CST WILL BE
ACCOMPANIED BY A BELT OF 25-30 KT MID LVL SELY FLOW ON ITS NRN
PERIPHERY. SCTD TSTMS...ASSOCIATED BOTH WITH THIS SYSTEM AND WITH
SEA BREEZE CIRCULATIONS...MAY GROW INTO RELATIVELY FAST-MOVING
CLUSTERS/BANDS THAT COULD YIELD ISOLD DMGG WIND GUSTS THIS
AFTN/EARLY EVE.

SHORT WAVE EARLY THIS AFTERNOON OVER CENTRAL SD WILL MOVE NE TO
THE UPPER GREAT LAKES BY LATE TONIGHT. THIS WILL DRIVE SURFACE LOW
PRESSURE...CURRENTLY NEAR KFSD...TO NEAR THE TWIN CITIES BY THIS
EVENING AND ACROSS MUCH OF WI OVERNIGHT. SEVERE WEATHER IS
IMMANENT FOR WEST CENTRAL MN AND A TORNADO WATCH IS IN EFFECT
UNTIL THIS EVENING. COMPLICATING MATTERS FOR EASTERN AREAS IS THE
MID LEVEL CAP OVERHEAD. TAMDAR DATA FOR KSUX...KMSP AND KBRD
SHOWING TEMPS NEAR 15 DEG C AT 700 MB. THIS SHOULD AID IN KEEPING
STORMS AT BAY LOCALLY THROUGH MUCH OF THE AFTERNOON. HOWEVER...AS
EVENING APPROACHES...HEIGHT FALLS AND CAA ALOFT WILL BEGIN TO
ERODE THE CAP...LEADING TO SEVERE STORMS BEING POSSIBLE OVER
EASTERN MN AND WEST CENTRAL WI. INSTABILITY AND SHEAR PARAMETERS
ARE EXTREME...SO THE THREAT FOR TORNADOES IS INCREASING ALONG THE
WARM FRONT AS WE HEAD INTO THE LATE AFTERNOON HOURS. HENCE..A
SIGNIFICANT SEVERE WEATHER EVENT MAY BE UNFOLDING.
