DEEP CONVECTION WILL BE QUITE SPARSE THROUGH THE DAY2 PERIOD THOUGH

FORECAST SOUNDINGS ACROSS THIS REGION SUGGEST ISOLATED THUNDERSTORMS
ARE POSSIBLE...INITIALLY OVER NRN WY...THEN SPREADING/DEVELOPING
NEWD INTO ND. OTHER ISOLATED THUNDERSTORMS COULD ALSO DEVELOP OVER
THE HIGHER TERRAIN OF WRN CO INTO SRN WY WHERE DEEPENING WLY FLOW
WILL BE OBSERVED IN ASSOCIATION WITH STRONG BAROCLINIC ZONE.

THUNDERSTORMS COULD LINGER AFTER DARK ACROSS THE DAKOTAS WHERE WEAK
ELEVATED INSTABILITY WILL EXIST ALONG FRONTAL ZONE.
