AREAS AFFECTED...SERN ND...NERN SD...NWRN MN

CONCERNING...CONVECTIVE TRENDS 

VALID 251820Z - 252015Z

...THUNDERSTORMS ARE EXPECTED TO INCREASE IN AREAL COVERAGE ACROSS
ERN ND INTO NWRN MN...

THUNDERSTORMS HAVE RECENTLY INCREASED ALONG LEADING LOW LEVEL
CONFLUENCE ZONE FROM NERN SD...INTO NWRN MN.  THIS ACTIVITY WILL
LIKELY EVOLVE INTO MULTIPLE BANDED STRUCTURES AS IT MOVES DOWNSTREAM
INTO NRN MN OVER THE NEXT FEW HOURS.  LOW LEVEL LAPSE RATES ARE
QUITE WEAK ACROSS THIS REGION WHICH SHOULD ULTIMATELY LIMIT
INSTABILITY...AND SEVERE POTENTIAL.

HOWEVER...PARTIAL CLEARING ACROSS CNTRL SD WILL AID AIRMASS
DESTABILIZATION ALONG SRN FRINGE OF ONGOING CONVECTION OVER THE NEXT
FEW HOURS.  WITH TIME STRONGER STORMS MAY EVOLVE ACROSS ERN
SD...POSSIBLY REQUIRING FURTHER ACTION LATER THIS AFTERNOON.
