...TSRA/SEVERE POTENTIAL OVERNIGHT CURRENT FORECAST CONCERN...

00Z SFC ANALYSIS PLACES STATIONARY FRONT JUST SOUTH OF ND BORDER
BETWEEN ABERDEEN AND WAHPETON. WILDLY UNSTABLE AIRMASS IN VICINITY
OF THIS BOUNDARY WITH LI/S AS LOW AS -13C BUT WARM MID-LEVEL TEMPS
HAVE SUPRESSED CONVECTION ACROSS MOST OF ND/SD ASIDE FROM FAR WEST. A
FEW CLUSTERS OF STORMS HAVE FIRED ON BACSKIDE OF RIDGE AND HAVE
RIDDEN UP TOWARD FAR WRN ND/ERN MT. WHILE TOPS ARE QUITE
COOL...TREND HAS BEEN FOR WEAKENING AS THEY ENTER COOLER/STABILIZED
ENVRINMENT WELL NORTH OF FRONT WHERE LOW LEVEL CAA IS
OCCURRING...ALONG WITH SOME INTRUSION OF LOWER TD/S IN N/NE FLO.
MSAS INDICATES AN IMPRESSIVE INSTABILITY GRADIENT ACROSS SOUTHERN
1/2 OF ND...WITH MAX WAA NOW BEGINNING TO SHIFT A BIT FURTHER WEST
INTO NCNTRL SD AS LOW LEVEL JET SHOULD INCREASE THERE...PULLING
FRONT BACK NORTH OVERNIGHT.

U/L JET ENERGY ALONG WITH VORTS RIDING ON BOTH SIDES OF RIDGES
APPEAR TO BE THE MECHANISMS THAT MAY PROVIDE ENOUGH SUPPORT ON EDGE
OF CAP TO CAUSE ELEVATED CONVECTION NORTH OF FRONT. TWO SUCH AREAS
WOULD BE SW ND ARCING NE TOWARDS NE ND...AND ANOTHER ONE IN FAR
NE CWA SLIDING SE THRU ERN MN AND WI. MESO-ETA HAS NAILED THE FIRST
AREA OF CONVECTION IN MT AND IT WOULD PLACE AN MCS BETWEEN KISN AND
KMOT AROUND 06Z WITH ANOTHER AREA OF TSRA JUST EAST OF KBJI. LLJ UP
TO 50KTS FEEDING TD/S AROUND 70 IN NRN SD WILL INTERACT WITH THE U/L
DYNAMICS ON EDGE OF CAP IN THESE AREAS...WITH THE CLUSTER TO THE NW
APPEARING TO BE OF MORE CONCERN WITH THE H7 FLO FROM THE W/SW.
A 50KT E FLO AT H85 IN NORTHERN SECTIONS WILL PROVIDE STRONG VERTICAL
SHEAR PROFILES FOR SUPERCELLS AND WBZ LEVELS WOULD BE BIT LOWER IN
THESE REGIONS ON THE END OF THE MID-LEVEL CAP SO LARGE HAIL WOULD BE
A THREAT.

WILL TINKER WITH TIMING OF TSRA IN CURRENT ZONE PACKAGE AND ADD SOME
CLOUD COVER TO SOUTHERN ZONES FOR ANY BLOWOFF FROM STORMS RIDING
NORTH. NO CHANGE EXPECTED TO TEMP RANGES.

.FGF...NONE.
