313 PM CDT TUE MAY 29 2012

.SHORT TERM...[NOW - WEDNESDAY NIGHT]

TONIGHT...CLOUD COVER WILL GRADUALLY BEGIN TO CLEAR UP FROM WEST
TO EAST AS THE EASTERN CANADA LOW PRESSURE SYSTEM MOVES OFF TO THE
EAST. RAIN SHOWERS COULD CONTINUE THROUGH THE NIGHT...BUT MOSTLY
ACROSS THE EASTERN FA...SUCH AS NORTHWESTERN WISCONSIN BECAUSE
THERE COULD BE LAKE INDUCED SHOWERS. HIGH PRESSURE WILL BUILD
INTO THE NORTHERN PLAINS AND THEN THE UPPER MIDWEST...SO THE WINDS
WILL WEAKEN TO VERY LIGHT AND VARIABLE FOR MUCH OF THE FA. THE
MINOR CONCERN FOR TONIGHT IS FROST DUE TO THE LIGHT WINDS AND COLD
OVERNIGHT TEMPERATURES IN SOME AREAS. THE THE NORTHERN AND WESTERN
FA HAVE THE GREATEST POTENTIAL SINCE TEMPERATURES SHOULD DROP OFF
TO THE MID 30S...AND THAT IS WHERE A FROST ADVISORY WILL BE
ISSUED. CONSIDERED THE THREAT OF FOG FOR TONIGHT...BUT NOT
CONVINCED OF IT. THE EVENING SHIFT WILL NEED TO REVALUATE THE
THREAT FOR FOG.

WEDNESDAY...HIGH PRESSURE WILL MOVE INTO THE UPPER
MIDWEST...BUT THE NORTHLAND WILL CONTINUE TO GET LIGHT NORTHERLY
WINDS. THE NAM SOUNDINGS INDICATE THE CONVECTIVE TEMPERATURES
SHOULD BE REACHED...SO EXPECT SOME SCATTERED CUMULUS FOR THE LATE
MORNING AND EARLY AFTERNOON. THE LATE AFTERNOON THOUGH SHOULD SEE
SOME CLEARING...WITH SUNNY OR MOSTLY SUNNY SKIES FOR MUCH OF THE
FA. THE EXCEPTION WILL BE THE SOUTHWESTERN FA WHERE THERE SHOULD
BE SOME CIRRUS ASSOCIATED WITH A SYSTEM THAT WILL MOVE THROUGH THE
CENTRAL/SOUTHERN PLAINS. SUNSHINE WILL BE THE MAIN FACTOR FOR
TEMPERATURES TOMORROW...WHICH WILL STILL BE ON THE COOL SIDE.
HOWEVER...AM BANKING ON ENOUGH SUNSHINE TO REACH HIGHS IN THE MID
TO UPPER 50S.

WEDNESDAY NIGHT...IT LOOKS LIKE ANOTHER COLD NIGHT AS HIGH
PRESSURE SITS OVER THE UPPER MIDWEST AND DEVELOPES NEARLY CALM
WINDS AND CLEAR SKIES OVER THE NORTHLAND. ADDED FROST TO THE
FORECAST WHERE THE LOWS SHOULD BE IN THE MID TO LOWER 30S.

.LONG TERM...[THURSDAY - MONDAY]

MODEL DIFFERENCES THURSDAY WITH THE HANDLING OF UPPER LOW
POSITION. HOWEVER...MODELS DO AGREE THAT SFC HIGH WILL PREVAIL
OVER THE FA. BULK OF THE MODELS MOVE THE UPPER LOW INTO EASTERN IA
THURSDAY NIGHT. GFS HAS SOME GRIDSCALE FEEDBACK ISSUES AND WILL
GIVE LESS WEIGHT. REGARDLESS...HAVE SOME POPS IN NW WI DUE TO
PROXIMITY TO THE UPPER LOW. THE UPPER LOW BEGINS TO RETROGRADE
NWWD FRIDAY AND WILL CONTINUE TO MENTION POPS. FA BECOMES UNDER
THE INFLUENCE OF NW FLOW ALOFT FRIDAY NIGHT THROUGH MONDAY AFTER
DEPARTURE OF THE UPPER LOW. EMBEDDED PIECES OF ENERGY WILL PASS
THROUGH THE FA WARRANTING A MENTION OF SOME SMALL POPS.

&&

.AVIATION...18Z TAFS

NUMEROUS VFR CIGS WITH AREAS OF MVFR CIGS IN VCNTY OF SHRA UNTIL
AROUND SUNSET. GUSTY SFC WINDS WILL ALSO PREVAIL UNTIL NEAR 02Z.
AFTER SUNSET...MVFR CIGS WILL PREVAIL AS LOW LEVEL INVERSION
TRAPS CLOUDS UNDERNEATH. EXPECT THE MVFR CIGS/CLOUDS TO IMPROVE TO
VFR WITH A CLEARING TREND.

.HYDROLOGY...
