Area forecast discussion, May 29, 9:19 AM EDT, 2 hours 3 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
919 AM EDT TUE MAY 29 2012

.SYNOPSIS...
A COLD FRONT STRETCHING FROM LOWER MICHIGAN ACROSS INDIANA AND
INTO ILLINOIS WILL MOVE EAST ACROSS THE LOCAL AREA TODAY. HIGH
PRESSURE WILL BUILD OVER THE REGION FROM THE NORTHWEST TONIGHT
THROUGH THURSDAY. AN AREA OF LOW PRESSURE WILL MOVE NORTHEAST
ACROSS THE GREAT LAKES REGION FRIDAY INTO SATURDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP IN ADVANCE OF THE
APPROACHING COLD FRONT THIS MORNING. THE EASTWARD PROGRESSION OF
THE STORMS IS FAIRLY SLOW. I WILL SLOW THE TIMING OF THE
PRECIPITATION AND HOLD ON TO IT A LITTLE LONGER IN THE WEST THIS
AFTERNOON. THE TREND WILL REMAIN SIMILAR IN THE EAST. I WILL LOWER
TEMPS A FEW DEGREES THIS AFTERNOON. THE DEBRIS CLOUD FROM THE
PRECIPITATION WILL LIKELY HOLD TEMPERATURES DOWN A FEW DEGREES.
THE LAMP DATA ONLY SHOWS TEMPERATURES REACHING THE UPPER 70S THIS
AFTERNOON. I WILL CONSERVATIVELY LOWER THE HIGHS INTO THE LOWER 80S.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/...
THE MIDDLE PART OF THE WEEK WILL BE QUIET AND COOL AS HIGH
PRESSURE BUILDS OVER THE REGION FROM THE NORTHWEST. DECENT COLD
AIR ADVECTION ACROSS LAKE ERIE EXPECTED ON WEDNESDAY BUT THINK THE
ATMOSPHERE WILL BE TOO DRY FOR ANYTHING MORE THAN SOME LAKE
INDUCED STRATO CU. THE SURFACE HIGH WILL FINALLY SHIFT TO THE
NORTHEAST LATE THURSDAY. THIS WILL ALLOW AN AREA OF LOW PRESSURE
OVER THE MID MISSISSIPPI VALLEY TO BEGIN MOVING NE. THE LOW WILL
REACH THE CENTRAL GREAT LAKES BY DAYBREAK SATURDAY. THE MODELS
HAVE BEEN TRENDING WESTWARD WITH THE LOW TRACK. THIS MEANS PRECIP
ASSOCIATED WITH THE SYSTEM WILL LIKELY NOT ARRIVE TILL SOMETIME
LATE THURSDAY NIGHT. WILL NEED HIGH POPS ON FRIDAY WITH GRADUALLY
DIMINISHING CHANCES FOR SHOWERS ON FRIDAY NIGHT. THE PERIOD WILL
BE COOL WITH HIGHS BOTH THURSDAY AND FRIDAY AVERAGING 5 TO 10
DEGREES BELOW NORMAL.

&&

.LONG TERM /SATURDAY THROUGH MONDAY/...
THE DIFFERENCES BETWEEN THE GFS AND ECMWF HAVE BEEN DECREASING BUT
THE ECMWF REMAINS MORE PROGRESSIVE THAN THE GFS WITH THE LOW MOVING
THROUGH THE LAKES FRI NIGHT THRU SAT NIGHT. STILL THINK THERE IS TOO
MUCH MOISTURE LEFT HANGING AROUND ON SUN NOT TO HAVE MORE OF A
CHANCE FOR SHRA SO POPS INCREASED ONCE AGAIN. CONTINUES SMALL CHANCE
FOR MON AS THREAT FOR WARM ADVECTION PRECIP LOOKS POSSIBLE.

&&

.AVIATION /13Z TUESDAY THROUGH SATURDAY/...
A BAND OF SCT TSRA...SOME POSSIBLY STRONG...WILL CONTINUE TO MOVE
EAST ACROSS THE AREA WITH THE COLD FRONT. IN GENERAL THE TSRA THREAT
LOOKS TO BE ENDING IN TOL AND FDY BY 14Z...MFD AND CLE BY 16Z...ERI
AROUND 18 OR 19Z AND CAK...YNG AROUND 20Z. VFR SHOULD PREVAIL EXCEPT
DURING THE HEAVIER RAIN IN THE TSRA.

DRY AIR QUICKLY SPREADS IN BEHIND THE COLD FRONT AND CLOUDS DECREASE
WEST TO EAST MIDDAY INTO EARLY EVENING WITH LITTLE CLOUDINESS
CONTINUING TONIGHT. SW WINDS OF 10 TO 20 KNOTS TURN WEST WITH FROPA
THEN WNW TONIGHT WITH A SECONDARY COLD FRONT.

.OUTLOOK...NON VFR POSSIBLE IN WIDESPREAD SHRA FRIDAY INTO SATURDAY.

&&

.MARINE...
WITH TEMPS SO WARM STILL NOT SURE IF SCA CONDITIONS WILL DEVELOP
BEHIND THE COLD FRONT LATER TODAY. FOR NOW WILL NOT RAISE GUIDANCE
THAT MUCH AND STAY BELOW ANY SCA. SECONDARY COLD FRONT MOVES THROUGH
TONIGHT THEN PRESSURE GRADIENT TIGHTENS WED SO NW FLOW WILL PROBABLY
INCREASE ENOUGH FOR MARGINAL SCA CONDITIONS LATE WED THROUGH THU
MORNING.

AS HIGH RIDGES EAST INTO THE EASTERN LAKES THE FLOW SHOULD DIMINISH
SOME AND TURN NE FOR THU NIGHT. LOW PRESSURE SHOULD MOVE NE ACROSS
THE DETROIT AREA LATER FRI. THE NE TO E FLOW AHEAD OF THE LOW WILL
INCREASE TO SCA LEVELS THEN WINDS WILL BE CHANGEABLE BUT SHOULD
MAINLY VEER AS THE LOW CROSSES SE MI BEFORE LINING UP OUT OF THE SW
THEN WEST WITH A SCA LIKELY TO CONTINUE WELL INTO SAT.
