AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
319 PM CDT SAT MAY 26 2007

.SHORT TERM...MAIN FORECAST CHALLENGE IS PRECIPITATION. THE LATEST
SURFACE ANALYSIS HAS THE LOW PRESSURE SYSTEM CENTERED BETWEEN FAR
AND BJI...WITH AN INVERTED TROF EXTENDING N ALONG A TVF TO ROX LINE
AND A COLD FRONT EXTENDING ALONG A DTL AND FFM. CURRENT KMVX RADAR
TRENDS SHOW PRECIPITATION BAND REMAINING OVER N HALF OF AREA...WITH
AN OVERALL SLOW WEAKENING TREND. THEREFORE...WILL ALLOW FLASH
FLOOD WATCH TO EXPIRE. HOWEVER...SURFACE PRESSURE GRADIENT HAS
STRENGTHENED AS WINDS TURN N IN E ND...ALLOWING WIND SPEEDS TO
INCREASE INTO THE 30 TO 40 MPH RANGE. THEREFORE...WILL ISSUE A
WIND ADVISORY FOR THE REMAINDER OF THE DAYLIGHT HOURS THIS EVENING.

THEN...SURFACE HIGH PRESSURE MOVES INTO CENTRAL ND BY 12Z SUN...
ALLOWING THE WINDS TO DIMINISH AND THE SKY TO CLEAR. WITH
TEMPERATURES ALREADY IN THE 35 TO 40 DEGREE RANGE IN THE DVL AREA
AND EXPECTED TO RADIATE DOWN TO NEAR 35 UNDER THE RIDGE AXIS...WILL
ISSUE A FROST ADVISORY FOR PARTS OF NORTHEAST AND EAST CENTRAL ND
FOR 06Z TO 12Z TONIGHT.

HIGH PRESSURE WILL MOVE THROUGH THE AREA FOR SUN AND SUN NIGHT...SO
KEPT THE FORECAST DRY WITH TEMPERATURES RISING TO NEAR NORMAL.  THEN
ON MON...THE NEXT LOW PRESSURE SYSTEM MOVES OUT INTO THE N PLAINS...
BRINGING PERIODIC CHANCES FOR THUNDERSTORMS TO THE AREA INTO THE
MIDDLE PART OF THE WEEK.

.LONG TERM (WED-SAT)...A COLD CORE UPPER LEVEL LOW WILL DRIFT
ACROSS THE N PLAINS WED INTO EARLY THU. THIS HAS THE POTENTIAL TO
PRODUCE SOME SHOWERS...AND COOLER TEMPS. THEREAFTER...AN UPPER
LEVEL RIDGE WILL BUILD INTO THE N PLAINS PROVIDING DRY AND
SEASONABLE TEMPS FOR THE REST OF THE WEEK. ANOTHER DISTURBANCE
WILL MOVE INTO THE REGION NEXT SAT...AND PROVIDE A CHANCE FOR
THUNDERSTORMS SO WILL MENTION...ALTHOUGH TIMING THIS FAR OUT IS
TOUGH.

&&

.AVIATION...IFR CONDITIONS WILL CONTINUE IN THE N VALLEY WHERE SOME
RAIN SHOULD PERSIST THROUGH AROUND 02Z. FURTHER S AND E...EXPECT
MVFR CONDITIONS TO LINGER...WITH BJI SEEING THE POTENTIAL FOR SOME
IFR CONDITIONS AFTER SUNSET. THE VALLEY TAF SITES (GFK/FAR) SHOULD
CLEAR AROUND 06Z...WITH BJI SEEING CLEARING AROUND 12Z ON SUN. THIS
UPPER LOW HAS CAPTURED THE SFC LOW THOUGH...SO THIS COULD DELAY
CLEARING WHICH WILL NEED TO BE WATCHED.

.FGF WATCHES/WARNINGS/ADVISORIES...
ND...WIND ADVISORY UNTIL 10 PM CDT THIS EVENING FOR NDZ006>008-
