.DISCUSSION...
MAIN ACTION THIS EVENING IS STAYING WELL WEST OF THE FA...MOSTLY
CONFINED TO AN AREA AROUND/SOUTH OF KBIS. PRETTY BIG STORMS THOUGH
...PRODUCING SOME BASEBALL SIZED HAIL IN THE KHEI AREA. THIS ACTION
IS FORMING IN THE GRADIENT OF MUCH WARMER/MORE HUMID AIR...A SLICE
OF SOUTHWEST ND GOT INTO THE 90S TODAY WITH DEW POINTS IN THE MID
60S. WEAK SFC HIGH WITH NORTHEAST/EAST WINDS IN OUR FA KEEPING
THINGS PRETTY DRY. SOME HIGH BASED SHOWERS OVER NORTHWEST MN...BUT
THESE REALLY LOOK WORSE ON RADAR THAN THEY ACTUALLY ARE (MOSTLY
SPRINKLES). ONE STORM WORKING INTO THE KDVL REGION...BUT THE FURTHER
EAST IT GETS...THE MORE IT SHOULD WEAKEN. TOOK OUT THUNDER MENTION
FOR NORTHWEST MN AND KEPT IT ONLY FOR THE WESTERN/SOUTHERN FA. MOST
OF THE CURRENT ACTIVITY WILL HAVE A HARD TIME STAYING TOGETHER AFTER
DARK...AS 850MB WINDS PRETTY ANEMIC FOR OUR AREA (10-15KTS AT BEST).
IF ANYTHING CAN STAY TOGETHER...AT BEST IT MAY CLIP OUR FAR
SOUTHWEST FA. THEREFORE WILL KEEP THE ISOLATED THUNDER MENTIONED
ONLY IN THE SOUTH AFTER MIDNIGHT. OVERALL...PCPN CHANCES LOOKING
PRETTY POOR IN OUR FA. CLOUDS WILL PLAY HAVOC WITH TEMPS TONIGHT.
PRETTY ORGANIZED MID LEVEL CLOUDS ALL THE WAY BACK INTO SOUTHERN
SASKATCHEWAN...WHICH WILL TAKE A WHILE TO MOVE THRU. THINK THEY WILL
STAY IN MOST OF THE NIGHT AND HELP HOLD TEMPS UP.

&&

.AVIATION...
ELECTED TO KEEP ANY PCPN MENTION OUT OF THE TAFS ALTHOUGH DID KEEP
SOME VICINITY SHOWERS THROUGH MIDNIGHT. CLOUDS LIKELY TO STAY IN
MOST OF THE NIGHT...ALTHOUGH NOT AFFECT VFR CONDITIONS AT ALL.

&&

.FGF WATCHES/WARNINGS/ADVISORIES...
ND...NONE.
MN...NONE.
