Area forecast discussion, May 23, 3:02 PM CDT, 2 hours 9 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 302 PM CDT TUE MAY 23 2006 .DISCUSSION...TONIGHT THROUGH FRIDAY LOW PRESSURE CURRENTLY ALONG THE MT/ND BORDER. A WARM FRONT MEANDERS SOUTHEAST FROM THE LOW TO SOUTHWEST MN WHILE A COLD FRONT CURVES SOUTHEAST FROM THE LOW TO CENTRAL NEBRASKA AND WESTERN KANSAS. SCATTERED THUNDERSTORMS FORMING FROM WEST OF KATY TO NORTH OF KLBF ATTM. 12Z NAM CONVECTIVE PARAMETERS POINT TO SEVERE STORMS LATE THIS AFTERNOON AND EVENING ALONG AND WEST OF THE I-29 CORRIDOR. BETTER THAN 100 J/KG OF ML CAPE TO 3KM INDICATED AHEAD OF THE COLD FRONT THIS EVENING ALONG WITH VERY FAVORABLE 0-1KM AND 0-6KM BULK SHEAR VALUES. BEST ML CAPE TO 3KM PUSHES INTO OUR FAR WESTERN CWA AROUND MID EVENING AND THEN SLIDES DOWN INTO CENTRAL IA AFTER MIDNIGHT. HENCE...SOME CONVECTION EXPECTED OVER WEST CENTRAL AND SOUTHWEST MN LATE THIS AFTERNOON AND EARLY THIS EVENING ALONG THE WARM FRONT WITH SEVERE STORMS BECOMING MORE LIKELY BY MID EVENING. NAM DIFFERENTIAL TEMPERATURE ADVECTION SCHEME SHOWING A SMALL POSITIVE SIGNATURE PASSING ACROSS THE SOUTHERN THIRD OF MN OVERNIGHT WITH A MUCH STRONGER SIGNAL OVER EASTERN NE AND IA. THEREFORE...HAVE HIGHEST POPS OVERNIGHT ACROSS SOUTHERN MN AS THUNDERSTORMS MOVE THROUGH. HELD ON TO LIKELY POPS WEDNESDAY MORNING FOR THUNDERSTORMS ACROSS WEST CENTRAL WI AS THE FRONTAL BOUNDARY MOVES THROUGH. REMAINDER OF WEDNESDAY INTO EARLY THURSDAY WILL BE DOMINATED BY A VERTICALLY STACKED LOW PRESSURE SYSTEM PASSING SLOWLY SOUTHEAST ACROSS THE CWA. INDICATED 45 TO 60 PERCENT POPS THROUGH THE PERIOD. NAM LAYER Q-VECTOR CONVERGENCE BECOMES PRETTY STRONG ACROSS THE CWA WEDNESDAY AFTERNOON/NIGHT. A SLOW DRYING ACROSS THE WESTERN CWA EXPECTED ON THURSDAY WHILE SHOWERS CONTINUE OVER EASTERN MN AND WEST CENTRAL WI. DRY WEATHER THEN EXPECTED THURSDAY NIGHT AND FRIDAY. HIGH TEMPERATURES WILL BE BACK ON THE RISE STARTING FRIDAY. LONGER TERM...FRIDAY NIGHT THROUGH TUESDAY A STRONG RIDGE OVER THE CENTRAL PACIFIC...INDICATED BY WARM SSTS AND ANOMALOUS H5 HEIGHTS...HAS BEGUN TO AMPLIFY...FEEDING ENERGY INTO AN ALREADY WELL DEVELOPED ALEUTIAN LOW. THE AMPLIFICATION OF THE PACIFIC RIDGE WILL ALSO NUDGE THE LOW INTO THE NORTHERN ROCKIES...AFFECTING THE TROUGH CURRENTLY RESIDING OVER THE NORTHEASTERN UNITED STATES THROUGH VORTICITY REDISTRIBUTION. AS THE NEW ENGLAND LOW BEGINS TO PROGRESS EASTWARD INTO THE ATLANTIC WITH THE MEAN FLOW...AN ANOMALOUS RIDGE WILL BUILD IN BEHIND IT. THIS PATTERN...REFLECTING A POSITIVE PHASE AO AND NEGATIVE PHASE PNA...IS SUPPORTED BY A VARIETY OF CURRENT MODEL SOLUTIONS...INCLUDING THE NCEP NMC ENSEMBLE...NAM...GFS...AND DGEX. OVER THE MPX FORECAST AREA...THE MOST APPARENT INFLUENCES OF THE ANOMALOUS EASTERN US RIDGE WILL BE ABOVE AVERAGE TEMPERATURES AND INCREASED SOUTHERLY FLOW OVER THE MEMORIAL DAY WEEKEND. RELATIVELY DRY AND CAPPED AIR WILL LIKELY PREVENT ANY PRECIPITATION...UNTIL FORCING RESULTING FROM A FRONTAL PASSAGE ON MONDAY ALLOWS FOR THE RELEASE OF INSTABILITY BELOW THE INVERSION. ACCORDINGLY...POPS AND WX WERE REMOVED DURING THE FRIDAY NIGHT TIME FRAME...AND INCREASED AFTER 06Z MONDAY. WINDS WERE ADJUSTED SLIGHTLY TO ACCOUNT FOR A SLOWER MODEL SOLUTION FOR THE SYSTEM PASSING OVER THE CWA ON MONDAY. THE COMBINATION OF A DEVELOPING OMEGA BLOCK OVER THE CENTRAL ATLANTIC AND COOL WATERS GENERATED BY RECENT STORMINESS ALONG THE EASTERN SEABOARD OF THE US...WILL HELP TO SUPPORT THE PREVIOUSLY MENTIONED ANOMALOUS RIDGE. THIS REINFORCEMENT WILL ULTIMATELY PROVIDE SOME PERSISTENCE TO THE WEATHER REGIME OVER THE UNITED STATES...AT LEAST THROUGH THE NEXT TWO WEEKS. && .MPX WATCHES/WARNINGS/ADVISORIES... MN...NONE.
