AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
230 PM CDT MON APR 7 1997

MAIN FOCUS FOR TONIGHT WILL BE HOW HARD TO HIT THE -SN AND
THE POSSIBILITY FOR RECORD LOW TEMPS.

CANADIAN STORM CIRCULATION IS STRETCHING E-W AT 19Z WITH MINIMAL
SWD ROTATION ON THE BACK SIDE INTO MN. ONE ARE OF ENERGY IS EVIDENT
MOVG W FROM JAMES BAY ALONG THE AXIS AND WILL LIKELY BE THE ONE TO
WATCH FOR TIMING OF SNOW SHOWERS. BUT IT LOOKS LIKE THAT ONE WOULD
CLIP NERN MN AND NWRN WI WITHOUT MOVG TOO FAR S INTO E-C MN OR CNTRL
WI.  THE NGM AND ETA DIVERGE IN THE FIRST 24-36 HOURS IN HANDLING
THIS LO LVL MSTR. NGM IS CONSIDERABLY MORE MOIST WHICH ACCOUNTS FOR
THE HIGHER POPS. BASED ON THE ITEMS STATED ABOVE, WE BELIEVE THAT THE
ETA HAS A BTR HANDLE ON THE SITUATION.  SO A 40 OR EVEN 30 PCT
POP WOULD BE OK. HWVR...FOR CONTINUITY...ITS PROBABLY OK TO LEAVE
IT AT 40 PCT.

SECONDLY, TEMPS TONIGHT WILL BE NEAR RECORD READINGS. AT DLH THE
RECORDS ARE +5 TONIGHT AND 8 ON THE 9TH.
FOR INL, THE RECORDS ARE +2 BOTH TONIGHT AND TUESDAY NIGHT.
WE BELIEVE THAT A MENTION OF NEAR RECORD TEMPS WOULD BE
OK TONIGHT. WE PLAN TO ISSUE A PNS STATING THE ABOVE-
MENTIONED RECORDS. WE WILL DO SO ONLY AFTER COORDINATION
AND IF MKE/MPX AGREE. A PNS WOULD TAKE SOME PHONE CALL
PRESSURE OFF THE EVENING CREW.
