AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
403 AM CDT SAT JUN 20 2009

.DISCUSSION...FORECAST FOCUS IS ON INCREASING WARMTH AND RESOLVING
PRECIPITATION CHANCES.

TODAY-
SIGGY VORT MAX SHIFTING INTO EASTERN GREAT LAKES. WATER VAPOR/RUC
COMBO SHOWS PLENTY OF DAVA WITH SUBSTANTIAL DRYING/SUBSIDENCE IN
WAKE OF VORT MAX. SURFACE FRONT/TROUGH ALSO HAS SHIFTED
EAST...THOUGH DRYING IN LOW LAYERS RATHER SLUGGISH. TEMPS WELL INTO
THE 80S BASED ON 850/925 TEMP CONSIDERATIONS. ENOUGH OF A BREEZE AND
MIXING AT PLAY EAST OF SURFACE/850 RIDGE AXES TO KEEP LAKE BREEZE
LARGELY OUT OF THE PICTURE.

TONIGHT-
SURFACE/850 RIDGE AXES SLIDE EAST INTO THE STATE. QPF EVOLVES WITH
DEVELOPING WAA ON BACK SIDE OF HIGH. PREFER THE MIODDLE GROUND
APPROACH OF ECMWF...WHICH WOULD STILL KEEP THE CWA DRY. LIGHT WIND
REGIME...MAINLY CLEAR SKIES AND MOIST LOW LEVELS DUE TO RECENT
RAINS...SUPPORTS RETAINING PATCHY FOG IN GRIDS.

SUNDAY-
A WEAK WAVE RIDES NORTHEAST ON WESTERN SIDE OF RIDGE. INSTABILITY
NOT OVERLY IMPRESSIVE ON BUFKIT SOUNDINGS. POSITION OF LIFT RELATED
TO VORT AND WAVE AND LESS INFLUENCE OF RIDGE SUGGUEST HIGHER POPS IN
THE WEST. IN ADDITION THERE IS A 20 TO 30 KNOT LLJ WITH MOISTURE
ADVECTION AIMED INTO THE SW CWA.

MONDAY-
INFLUENCE OF THIS RIDGE RIDER WANES WITH TIME SO HAVE SLIGHT
CHANCE ONLY IN THE MORNING. 925 TEMPS FROM 00Z ECMWF NEAR 28C BY
00Z TUESDAY. THATS THE HIGHEST. FOR NOW WILL STEER TOWARDS
MENTIONING LOW 90S IN THE WEST BUT NOT GO BEYOND THAT FOR NOW...AS
LINGERING CLOUDS COULD VERY WELL HAVE A SAY ON THINGS FOR A
WHILE...BUT NOT AS MUCH IN THE WEST.

TUESDAY-
UPPER RIDGE BUILDS BIG TIME WITH GFS SHOWING ERRONEOUS VORTS WITHIN
THE RIDGE. WILL DISCOUNT AND GO WITH MUCH CLEANER LOOK OF THE ECMWF.
WILL ALSO LEAN A BIT TOWARDS THE ECMWF 925 TEMPS AS GFS VALUES
PROBABLY CONTAMINATED...SO AT LEAST LOW 90S EXPECTED.

WEDNESDAY-
UPPER RIDGE PROGGD TO FLATTEN A BIT AS ENERGY RIDES TOWARDS THE
AREA. HOWEVER THERMAL RIDGE INTO CWA. CONVECTION COULD VERY WELL
HOLD OFF UNTIL WEDNESDAY NIGHT...ALLOWING TEMPS TO REALLY COOK PRIOR
TO FROPA.

&&

.AVIATION...HIGH PRESSURE WILL BUILD OVER THE UPPER MISSISSIPPI
VALLEY. PATCHY IFR FOG AND STRATUS EARLY THIS MORNING. OTHERWISE
MAINLY SCATTERED AFTERNOON CU AROUND 5 THSD FT.

INCREASING HIGH CLOUDS TONIGHT AS LOW PRESSURE DEVELOPS OVER THE
NORTHERN ROCKIES.
