CHANCE OF CONVECTIVE PRECIPITATION THROUGH MONDAY NIGHT.

.LONG TERM...TUESDAY THROUGH FRIDAY. ON TUESDAY THE H500 RIDGE IS TO
THE WEST WITH NWLY FLOW ALOFT OVER ND...BUT THE GFS CONTINUES TO
BRING A SMALL VORT/SHORTWAVE THROUGH THE RIDGE AND WILL KEEP LOW
PRECIP CHANCES IN THE WEST ON TUESAY AFTERNOON. THE WESTERN RIDGE
CONTINUES TO BUILD NEXT WEEK AND NORTH DAKOTA IS ON THE EASTERN EDGE

THROUGH...SO INTRODUCED PRECIP ON FRIDAY NIGHT.
