AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
325 PM CDT MON MAY 29 2006

.DISCUSSION...TODAY THROUGH THURSDAY NIGHT
FORECAST CONCERN NEAR TERM...CONVECTIVE DEVELOPMENT OVER SOUTHEAST
CWA AT LEAST THROUGH THE MORNING.  SOUTHWEST FLOW ALOFT HAS SLOWED
MOVEMENT OF SURFACE FRONTAL BOUNDARY NEAR A MEDFORD/WINONA LINE AS
OF 3AM.  WATER VAPOR IMAGERY SUGGESTS WEAK SHORT WAVE LIFTING

MORNING.  WILL HAVE TO RETAIN SOME POPS AT LEAST DURING THE MORNING
HOURS AS SYSTEM MOVES THROUGH. DEBRIS CIRRUS WILL DISSIPATE DURING
THE MORNING WITH SUNSHINE ANTICIPATED MUCH OF THE DAY...AS DRIER AIR
MOVES IN.  WILL USE MET GUIDANCE TEMPERATURES AS SIGNIFICANT COOLING
NOT REALLY ANTICIPATED.

MODELS SHOW SOME DISCREPANCY IN TIMING OF NEXT SHORT WAVE.  TRENDS
OF GFS WOULD BRING BEST CHANCE OF PRECIPITATION COMING IN WEDNESDAY
NIGHT OVER MUCH OF THE CWA. WILL FOLLOW THIS TREND AND MENTION
HIGHER POPS THEN.  SYSTEM PULLS EAST THURSDAY WITH ONLY SLIGHT
COOLING ANTICIPATED.  AGAIN ACCEPT WARMER MET GUIDANCE OVERALL.

LONGER TERM...FRIDAY THROUGH TUESDAY
MAINTAINED SOME LOW CHANCE POPS OVER THE NORTHERN CWA DURING THE
UPCOMING WEEKEND WITH THE SURFACE WAVE MOVING THROUGH. DRY WEATHER
THEREAFTER. HIGH TEMPERATURES FORECAST ABOUT 5 DEGREES ABOVE
CLIMATOLOGY FRIDAY AND SATURDAY THEN NEAR CLIMATOLOGY SUNDAY AND
MONDAY. HEAT BEGINS TO RETURN ON TUESDAY WITH UPPER LEVEL RIDGING
