Area forecast discussion, Jun 10, 3:41 PM CDT, 11 hours 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
341 PM CDT TUE JUN 10 2008

.SHORT TERM...TUESDAY THROUGH FRIDAY NIGHT...

A STRONG MIDDLE LEVEL LOW OVER NORTHERN IDAHO IS INDUCING INTENSE
LEE CYCLOGENESIS ACROSS THE NORTHERN HIGH PLAINS AS RESULTANT
NORTHERN PLAINS LOW-LEVEL MOISTURE ADVECTION HELPS SET THE STAGE
FOR WIDESPREAD MODERATE TO HEAVY RAINFALL ACROSS WESTERN AND
CENTRAL NORTH DAKOTA BEGINNING THIS EVENING. THE GREATEST
DYNAMIC FORCING APPEARS TO BE ASSOCIATED WITH UPPER LEVEL JET
COUPLING AND STRONG RESULTANT SECONDARY CIRCULATIONS OVER CENTRAL
MONTANA...ACCORDING TO TUESDAY UPPER AIR OBSERVATIONS AND
SATELLITE IMAGERY.

THERE ARE SOME QUESTIONS REGARDING AMOUNTS AND LOCATION OF
PRECIPITATION. AT PRESENT...IT APPEARS THAT THE BEST CHANCE FOR
HEAVY RAINFALL WILL BE NORTH OF THE WARM FRONT AS SLANTWISE
ASCENT RELEASES CONVECTIVE INSTABILITY ACROSS SOUTHERN NORTH
DAKOTA AFTER 100 AM CDT WEDNESDAY. A SECONDARY MAXIMUM OF HEAVY
RAINFALL IS POSSIBLE ALONG THE SLOW-MOVING OCCLUDED FRONT MOVING
THROUGH WESTERN NORTH DAKOTA ON WEDNESDAY.

THEREAFTER...STRONG DYNAMIC FORCING ALOFT AND COOL MIDDLE LEVEL
TEMPERATURES SHOULD BE ABLE TO OVERCOME DRY LOW LEVELS TO KEEP A
REASONABLE CHANCE FOR PRECIPITATION IN THE FORECAST THROUGH FRIDAY
EVENING. WITH ALL THE CLOUD COVER...PRECIPITATION...AND DYNAMIC
COOLING FORECAST...TEMPERATURES SHOULD REMAIN BELOW AVERAGE FOR
THE ENTIRE SHORT RANGE PERIOD.

.LONG TERM...SATURDAY THROUGH TUESDAY NIGHT
THE UPPER LEVEL FLOW WILL TURN NEARLY ZONAL SATURDAY BOUNDED BY TWO
UPPER LEVEL LOWS...ON IN ONTARIO AND THE OTHER OFF THE WEST COAST
WEST OF WASHINGTON.  THIS WILL ALLOW SHORT WAVES TO MOVE THROUGH THE
AREA AND THERE WILL BE A CHANCE OF PRECIP OFF AND ON THROUGH
SUNDAY.  BY MONDAY THE UPPER LEVEL LOW OFF THE WASHINGTON COAST WILL
HAVE DROPPED SOUTH ENOUGH TO BEGIN FORMING A RIDGE OF THE CENTRAL
PLAINS BRINGING WARMER DRIER WEATHER TO THE REGION MONDAY AND
TUESDAY.

&&

.AVIATION...AS THE SURFACE LOW AND TROUGH CONTINUE TO DEVELOP IN
EASTERN MONTANA AND WYOMING MOIST AIR OVERRUNNING THE SYSTEM HAS
BEEN DETECTED BY AREA RADARS.  LITTLE PRECIPITATION IS REACHING THE
GROUND...BUT AS THE SYSTEM CONTINUES TO DEVELOP AND THEN BEGINS TO
MOVE SLOWLY INTO THE PLAINS...CONDITIONS WILL WORSEN...CEILINGS AND
VISIBILITIES WILL LOWER IN RAIN AND FOG.  MVFR AND IFR CONDONES WILL
DEVELOP AND SPREAD ACROSS THE STATE BY LATE WEDNESDAY MORNING.

.BIS WATCHES/WARNINGS/ADVISORIES...
