FORECAST DISCUSSION FOR EASTERN NORTH DAKOTA AND NORTHWEST MINNESOTA
NATIONAL WEATHER SERVICE EASTERN ND/GRAND FORKS ND
250 AM CDT SAT JUN 28 1997

UNFORTUNATELY...DUE TO SEVERE WEATHER AND FLOODING HAVENT BEEN ABLE
SPEND ALOT OF TIME LOOKING AT DATA. FOR FIRST PERIOD MODELS DEVELOP A
WARM FRONT ACROSS CENTRAL MINNESOTA FROM LOW OVER SD WITH MAIN THREAT
FOR HEAVY RAIN AND SEVERE WX FOCUSED ON THIS REGION FROM QPF AND SWO
PROGS.  HOWEVER AM STILL CONCERNED ABOUT THREAT OF HEAVY RAIN/FLOODING
AND PSBL SVR WX LATER TODAY. WITH TDS FORECAST TO REMAIN IN THE MID TO
UPPER 60S AND RESIDUAL BOUNDARIES FROM OVERNIGHT CONVECTION ANY SFC
HEATING TODAY MAY CAUSE PROBLEMS. NGM LI'S ALSO KEEP MOST OF REGION
QUITE UNSTABLE WITH LI'S FROM -4 TO -8. SUGGEST KEEPING FLASH FLOOD
WATCH IN MOST OF REGION FOR TODAY. ALSO MAY HAVE TO MENTION THE RISK OF
SEVERE FOR SOUTH HALF OF CWFA. MOST ALL OF CWFA EXCEPT FOR MAYBE DVL
AREA HAS A FAIR CHANCE FOR TSRA. WITHOUT HAVING LOOKED AT MUCH MOS
TEMPS SEEM REASONABLE GENERALLY LOWER TO MID 80S FROM NORTH TO SOUTH.
