Tough crowd...now where did cookie go!

I was listening to a podcast from the weather radio network in the USA and saying the current setup is quite unusual , but the didn't really explain it well other then calling it the ring of fire.

is the setup across the usa unusual then and how so?

0502 PM CDT WED JUN 17 2009

AREAS AFFECTED...WRN AND CENTRAL SD/NWRN AND N CENTRAL NEB

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 172202Z - 172330Z

SEVERE/ISOLATED TORNADO POTENTIAL SHOULD INCREASE OVER THE NEXT FEW
HOURS -- POSSIBLY REQUIRING NEW WW ISSUANCE.

LATEST SURFACE ANALYSIS INDICATES A WEAK DRYLINE ACROSS SWRN SD W OF
THE BLACK HILLS...AND EXTENDING SWD INTO THE WRN NEB PANHANDLE.
LATEST KUDX /RAPID CITY SD/ WSR-88D REFLECTIVITY LOOP CONFIRMS THIS
BOUNDARY LOCATION.

WHILE INSTABILITY REMAINS MODEST ACROSS THIS REGION...A WELL-DEFINED
SHORT-WAVE TROUGH MOVING NEWD ACROSS CO/SWRN WY TOWARD THIS AREA
SHOULD SUPPORT AN INCREASE IN CONVECTION OVER THE NEXT FEW HOURS.
WITH ENHANCED SWLY MID-LEVEL FLOW ACCOMPANYING THIS FEATURE...SHEAR
WILL BECOME INCREASINGLY-SUPPORTIVE OF ORGANIZED/SEVERE STORMS.
ALONG WITH THREATS FOR ISOLATED DAMAGING WINDS AND HAIL WITH
STRONGER STORMS...LOCAL AREAS OF SELY LOW-LEVEL FLOW -- INCLUDING
INVOF THE BLACK HILLS -- COULD SUPPORT A LOCALLY-ENHANCED THREAT FOR
ISOLATED TORNADOES. IF STORMS INCREASE SUFFICIENTLY IN COVERAGE AS
CURRENTLY ANTICIPATED...WW COULD BE REQUIRED.

CONCERNING...SEVERE THUNDERSTORM WATCH 446...

VALID 172226Z - 180000Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 446
CONTINUES.

STRONG/LOCALLY-SEVERE STORMS CONTINUE IN AND CLOSE TO THE WW.

THUNDERSTORMS CONTINUE TO DEVELOP/MOVE NEWD ACROSS PARTS OF THE TX
AND OK PANHANDLES AND INTO SWRN KS ATTM. THIS AIRMASS IS
CHARACTERIZED BY 500 TO 1500 J/KG CAPE...ABOVE A DEEP MIXED LAYER
FEATURING SURFACE DEWPOINT DEPRESSIONS OVER 40 F IN SOME AREAS.

GIVEN THE POTENTIAL FOR SIGNIFICANT SUB-CLOUD
EVAPORATION/COOLING...STORMS SHIFTING ACROSS THIS AREA WILL REMAIN
CAPABLE OF PRODUCING STRONG/LOCALLY-DAMAGING DOWNBURSTS OVER THE
NEXT SEVERAL HOURS.

AREAS AFFECTED...PARTS OF SWRN PA / FAR E-CNTRL OH / WV PANHANDLE

CONCERNING...TORNADO WATCH 442...

VALID 172233Z - 172330Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 442 CONTINUES.

ISOLD TORNADO THREAT IN ADDITION TO LARGE HAIL/DMGG WINDS IS
EXPECTED TO CONTINUE INTO THE EARLY EVENING ACROSS PARTS OF MAINLY
FAR E-CNTRL OH / SWRN PA / WV PANHANDLE.

LATEST SURFACE ANALYSIS SHOWS LOW INVOF 20 MI NW CLE WITH A SEWD
DRAPING WARM FRONT TO PIT TO EKN. RECENT SATELLITE IMAGERY SHOWS A
WELL DEVELOPED ANVIL SHIELD ACTING TO REINFORCE EXISTING BAROCLINIC
ZONE THROUGH DIFFERENTIAL DIABATIC HEATING. ALONG AND TO THE W OF
THE BAROCLINIC ZONE OVER SWRN PA/FAR E-CNTRL OH...DEWPOINTS ARE IN
THE MID-UPPER 60S F. HERE...MODERATE POTENTIAL INSTABILITY
/1000-1500 J/KG MLCAPE ACCORDING TO OBJECTIVE FIELDS/ HAS NOSED UP
TO EXISTING BOUNDARY...AND WILL LIKELY SUPPORT CONTINUOUS AND
VIGOROUS UPDRAFTS THROUGH EARLY EVENING.

RECENT PBZ VWP DATA SHOWS RATHER A PRONOUNCED LOW LEVEL VEERING
PROFILE BENEATH 50 KT WLY 7 KM FLOW. THIS IS CONTRIBUTING TO
SUBSTANTIAL 0-1 KM SRH / 275 M2 PER S2/ BASED ON OBSERVED TUSCARAWAS
SUPERCELL MOTION. THIS WILL LIKELY SUPPORT CONTINUED LOW LEVEL
STORM ROTATION...AND LOW LFC/S /AOB 1000 M/ WILL REMAIN CONDUCIVE
FOR AN ISOLD TORNADO OR TWO...IN ADDITION TO LARGE HAIL AND DMGG
WINDS.

FURTHER S...RECENTLY DEVELOPED STORMS E OF CRW ARE DEVELOPING IN A
SIMILAR BUT FAVORABLY SHEARED ENVIRONMENT. THESE STORMS WILL
PROBABLY POSE A SEVERE THREAT WITH AN ISOLD TORNADO BEING POSSIBLE.
A LOCAL WW EXTENSION-IN-AREA MAY BE NEEDED FOR COUNTIES IN SERN WV.
