AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
341 PM EDT WED JUN 17 2009

.SYNOPSIS...
A COLD FRONT WILL MOVE SOUTHEAST OF THE AREA THIS EVENING. HIGH
PRESSURE WILL BUILD IN FROM THE NORTHWEST THURSDAY. FRIDAY AND
WARM FRONT WILL MOVE INTO THE AREA FROM THE SOUTHWEST AHEAD OF
HIGH PRESSURE IN THE CENTRAL PLAINS.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
SURFACE TROF FROM NORTHWEST OHIO SW INTO ILLINOIS. WARM FRONT
ACROSS NORTHEAST OHIO TO A LOW IN SERN LOWER MICHIGAN. UPPER
DISTURBANCE MOVING ACROSS THE NRN PORTIONS OF THE AREA. SSWLY LOW
LEVEL INFLOW JET ACROSS THE SERN COUNTIES WHERE BEST INSTABILITY
IS CURRENTLY LOCATED WITH LIS OF -5 OR SO. BEST CHANCE OF
CONVECTION WILL BE IN THE MOST UNSTABLE AIR ACROSS THE EASTERN
HALF OF THE AREA. ALSO CONCERNED ABOUT DEVELOPMENT WITH THE
SURFACE TROF TO THE WEST ALTHOUGH WESTERLY FLOW AHEAD OF AND
BEHIND THE BOUNDARY SO CONVERGENCE IS LIMITED. DYNAMICS ALSO A BIT
IN FRONT OF THE FEATURE. WILL GO WITH CHANCE POPS WEST QUICKLY
RAMPING UP TO CATEGORICAL CENTRAL AND EAST. WILL LOWER POPS A BIT
AFTER 06Z AS DIURNAL FORCING AND DYNAMIC FORCING DECREASES.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY NIGHT/...
WILL INCLUDE A SMALL CHANCE FOR MAINLY MORNING SHOWERS FAR
NORTHEAST FOR EXITING SYSTEM. TO THE WEST MOISTURE AND INSTABILITY
BEGIN TO INCREASE LATE IN THE DAY FROM THE SOUTHWEST AHEAD OF THE
APPROACHING WARM FRONT SO WILL HAVE CHANCE POPS FOR THAT.
OTHERWISE SHOULD BE DRY WITH HIGH PRESSURE BUILDING IN FOR THE
DAY. THURSDAY NIGHT AND FRIDAY THE WARM FRONT WILL CONTINUE TO
MOVE TOWARD/INTO THE AREA. WILL BRING MID/HIGH CHANCE POPS BACK TO
THE AREA ON THURSDAY NIGHT AFTER MIDNIGHT. FRIDAY WILL INCREASE TO
LIKELY...CONTINUING INTO FRIDAY NIGHT. SATURDAY THE NAM AND GFS
SHOW SOME DIFFERENCES IN THE UPPER SYSTEM MOVING ACROSS THE GREAT
LAKES WITH THE NAM STRONGER OF THE TWO. WILL NEED TO CONTINUE WITH
SHOWERS IN THE FORECAST WITH CHC POPS WEST AND LIKELY POPS EAST.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
UPPER LEVEL RIDGE WILL BUILD SLOWLY EAST TOWARD THE AREA OVER THE
EXTENDED PERIODS INTO NEXT WEEK BUT WILL BECOME NEARLY STATIONARY BY
WEDNESDAY.  LOW IS PROGGED TO MOVE OFF THE DELMARVA COAST AND THEN
BEGIN TO RETROGRADE BACK WEST TOWARD THE AREA. I THINK THE STRENGTH
OF UPPER LEVEL RIDGE SHOULD KEEP SHOWERS AND EXTENSIVE CLOUD COVER
FROM ADVANCING AS FAR WEST AS THE FORECAST AREA.

THE UPPER LEVEL RIDGE WILL SET UP A WARMING TREND WELL INTO THE
EARLY PART OF THE WEEK AS 1000 TO 500 MB THICKNESS INCREASES TO THE
570S. WITH CLOSE PROXIMITY OF UPPER LEVEL RIDGE IN THE
WEST...FORECAST AREA SHOULD REMAIN UNDER HIGH AND DRY CONDITIONS
MONDAY THROUGH THE END OF THE PERIOD. SOME LINGERING SHOWERS OVER
THE EAST ON SUNDAY WILL PULL OUT OF THE AREA.

I BUMPED UP TEMPERATURES A FEW DEGREES IN BOTH THE HIGHS AND LOWS.
LATEST GUIDANCE IS STARTING TO TREND TOWARD A WARMER SOLUTION AND
THIS MAKES SENSE DUE TO STRONG SUBSIDENCE EXPECTED TO DEVELOP.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
GENERALLY MVFR TO IFR CONDITIONS EXPECTED ACROSS THE AREA THIS
AFTERNOON NORTHEAST OF THE WARM FRONT. SOUTHWEST OF THE FRONT
CONVECTION IS DEVELOPING AS AIR MASS IS GRADUALLY DESTABILIZING AS
BREAKS OF SUN DEVELOP. THEN...WITH ALL OF THE RAIN OVER THE AREA
THIS MORNING AND AFTERNOON...MOIST AIR GROUND AND MOIST AIR MASS
WILL LIKELY CAUSE STRATIFORM CLOUDS TO DEVELOP WITH IFR CONDITIONS
THROUGH THE NIGHT. GRADUAL IMPROVEMENT EXPECTED FROM WEST TO EAST
IN THE MORNING WITH LINGERING MVFR IN THE EAST DURING THE MORNING
HOURS. WINDS EXPECTED TO BE MAINLY SOUTHWEST DIRECTION FROM
CLEVELAND TO AKRON CANTON AND WEST WHILE SOUTHEAST FLOW CONTINUES
NORTHEAST OF THAT LINE.

OUTLOOK...THURSDAY VFR. SCATTERED NON VFR CONDITIONS LIKELY WITH
SHOWERS/THUNDERSTORMS THURSDAY NIGHT INTO SATURDAY. SUNDAY AND
MONDAY VFR.

&&

.MARINE...
LOW PRESSURE IS JUST NOW MOVING OVER THE WEST END OF LERI.
ASSOCIATED WARM FRONT HAS MADE IT PAST KCLE WITH WINDS BECOMING SW
BEHIND THE FRONT.  THE LOW WILL MOVE EAST ACROSS THE LAKE TONIGHT
WITH WINDS QUICKLY BECOMING W BEHIND THE LOW.  S TO SE FLOW WILL
PERSIST ON THE EAST END MOST OF THE NIGHT.  THE LAKE WILL BE BETWEEN
SYSTEMS ON THURSDAY WITH W TO NW FLOW BECOMING LIGHT BY THE END OF
THE DAY.  ANOTHER LOW WILL APPROACH FROM THE W ON FRIDAY. STILL SOME
QUESTION AS TO WHAT TRACK THIS LOW WILL TAKE.  LATEST CONSENSUS IS
THAT THE LOW WILL PASS TO THE N OF THE LAKE FRIDAY NIGHT INTO
SATURDAY.  WINDS ON THE LAKE WILL START OUT SE FRIDAY AND THEN
BECOME SW BEHIND A WARM FRONT SET TO LIFT N OVER THE REGION.  W TO
NW FLOW STRONG ENOUGH FOR A POSSIBLE SMALL CRAFT ADVISORY CAN BE
EXPECTED FOR SATURDAY WITH LESSENING WINDS ON SUNDAY.  LIGHT FLOW
EXPECTED FOR MONDAY.
