AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
142 PM EDT WED JUL 17 2013

.SYNOPSIS...
A LARGE AREA OF HIGH PRESSURE WILL BE THE DOMINATING WEATHER FEATURE
THROUGH FRIDAY. THE HIGH PRESSURE WAS CENTERED OVER OHIO AND WILL
GRADUALLY SLIDE SOUTHEAST INTO THE CAROLINAS BY FRIDAY. A COLD FRONT
WILL MOVE SOUTHEAST ACROSS THE AREA SATURDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
BOOSTED PARTS OF THE NW TO CHANCE POPS. SUBSTANTIAL CU FIELD IS
DEVELOPING INTO SCATTERED SHOWERS AND STORMS ACROSS SRN LWR MI AS
PRE THE HRRR MODEL FORECAST. BELIEVE THIS WILL EXTEND INTO PARTS
OF NWRN OHIO AS WELL. ALSO EXTENDED THE SLIGHT CHANCE FOR NERN
OHIO INTO CRAWFORD COUNTY PA AND THEN IN TIME INTO THE AFTERNOON.

PREVIOUS DISCUSSION...

THE HEAT IS ON. THE DOG DAYS OF SUMMER HAVE ARRIVED AS A
VERTICALLY STACKED DOME OF HIGH PRESSURE FROM 500 MB DOWN THE
SURFACE REMAINS IN PLACE TODAY. THE HIGH PRESSURE WILL CONTINUE TO
PUMP HIGH DEW POINT AIR INTO THE FORECAST AREA TODAY WITH DEW
POINTS REACHING THE MIDDLE 70S...ESPECIALLY NEAR LAKE ERIE AND
WESTERN THIRD OF THE FORECAST AREA. THE COMBINATION OF THE HIGH
DEW POINTS AND RESULTING HIGH HUMIDITY ALONG WITH HOT AIR
TEMPERATURES WILL CAUSE HEAT INDEX VALUES TO REACH BETWEEN 100 AND
104 THIS AFTERNOON INTO THE EVENING HOURS. SO...WE DECIDED TO
HOIST A HEAT ADVISORY FOR THE WESTERN THIRD OF THE FORECAST AREA
FOR TODAY. THE REST OF THE FORECAST AREA WILL STILL BE HOT AND
HUMID BUT WILL KEEP HEAT INDEXES DOWN TO BETWEEN 98 AND 99 DURING
THE AFTERNOON AND EVENING.

AS FAR AS THUNDERSTORMS GO...THE SUPPRESSION OF THE HIGH PRESSURE
OVERHEAD...DECIDED TO NOT MENTION THUNDERSTORMS ANY PLACE IN THE
FORECAST AREA. THERE COULD BE AN ISOLATED THUNDERSTORM THAT DEVELOPS
BUT AREAL COVERAGE SHOULD BE SO MINIMAL THAT IT IS NOT WORTH
MENTIONING AT THIS TIME.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
THE DOME OF HIGH PRESSURE IS EXPECTED TO MOVE SLOWLY SOUTHEAST
TONIGHT INTO FRIDAY. THIS WILL SHIFT THE SUPPRESSION FROM THE HIGH
TO THE SOUTH. HOWEVER...THE HEAT AND HUMIDITY WILL CONTINUE TONIGHT
MAKING IT FEEL VERY UNCOMFORTABLE FOR SLEEPING. THE HEAT CONTINUES
TOMORROW WITH A GOOD CHANCE THAT WE WILL NEED TO HOIST ANOTHER HEAT
ADVISORY FOR A MUCH LARGER AREA. HEAT INDEX VALUES ONCE AGAIN REACH
BETWEEN 100 AND 104 DURING THE AFTERNOON AND EVENING HOURS ON
THURSDAY. LITTLE CHANGE IF ANY IS EXPECTED THURSDAY NIGHT INTO
FRIDAY AS HOT MUGGY CONDITIONS CONTINUE.

A REPRIEVE ARRIVES ON SATURDAY AS A COLD FRONT SLIPS SOUTH ACROSS
THE AREA. THIS SHOULD KNOCK TEMPERATURES DOWN A FEW PEGS AND
DEFINITELY LOWER DEW POINT TEMPERATURES AS WELL. THIS SHOULD RESULT
IN NOTICEABLY COOLER TEMPERATURES AND HUMIDITY LEVELS.

AS THE FRONT MOVES THROUGH THE AREA...THE POTENTIAL EXISTS FOR THE
THREAT OF SHOWERS AND THUNDERSTORMS ACROSS THE AREA.
THEREFORE...WILL HOLD ON TO THE LIKELY CATEGORY. MOISTURE ASSOCIATED
WITH THE COLD FRONT EXITS TO THE SOUTH FAIRLY QUICKLY AND WILL GO
AHEAD AND END THE THREAT FOR SHOWERS AND THUNDERSTORMS FROM NORTH TO
SOUTH IN THE AFTERNOON.  FAIR WEATHER RETURNS AGAIN FOR SATURDAY
NIGHT.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
A COOLER AREA OF HIGH PRESSURE WILL BE BUILDING INTO THE REGION ON
SUNDAY IN THE WAKE OF A COLD FRONT THAT SHOULD BE NEAR THE EAST
COAST. AN UPPER LEVEL TROUGH WILL THEN TAKE UP RESIDENCE ACROSS THE
GREAT LAKES REGION FOR MONDAY INTO TUESDAY. THERE MAY BE A PIECE OF
JET ENERGY THAT MOVES THROUGH THIS TROUGH FROM LATE MONDAY INTO
TUESDAY. THIS WILL BRING INCREASING CHANCES OF THUNDERSTORMS. THE
STRONGER PIECE OF ENERGY WILL LIKELY NOT ARRIVE UNTIL WEDNESDAY.

TEMPERATURES SUNDAY INTO MONDAY MAY BE SLIGHTLY BELOW SEASONAL
AVERAGES BUT WE WILL WARM AHEAD OF THE NEXT COLD FRONT THAT WILL
ARRIVE WEDNESDAY INTO THURSDAY.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
CONTINUED VFR CONDITIONS. ISOLATED AFTERNOON SHRA/TS WOULD LIKELY
BE ISOLATED TO JUST THE TOLEDO AREA. OTHERWISE FOCUS IS SOUTHEAST
OF OUR SITES. MAY HAVE SOME PATCHY MVFR BR/HZ TOWARD THU MORNING
BUT NOT MUCH. VFR AGAIN THURSDAY WITH EVEN LESS OF A CHANCE FOR
SHRA/TS.

.OUTLOOK...NON VFR IN PATCHY EARLY MORNING FOG.

&&

.MARINE...
HIGH PRESSURE CENTERED OVER THE WESTERN OHIO RIVER VALLEY WILL
GRADUALLY WEAKEN AS IT SHIFTS SOUTHEAST THROUGH FRIDAY. AS A COLD
FRONT APPROACHES ON FRIDAY IT APPEARS THAT SOUTHWESTERLY WINDS WILL
BE ON THE INCREASE. WINDS MAY INCREASE TO 15 TO 25 KNOTS ALLOWING
WAVES TO BUILD TO 3 TO 5 FEET FOR THE OPEN WATERS AND EASTERN HALF
OF THE LAKE. THESE STRONGER WINDS WILL PERSIST UNTIL A COLD FRONT
PASSES FRIDAY NIGHT INTO EARLY SATURDAY. SO WITH THAT SAID IT
APPEARS A SMALL CRAFT ADVISORY WILL BE NEEDED FRIDAY INTO AT LEAST
SATURDAY MORNING. HIGH PRESSURE WILL BUILD OVER THE LAKE SATURDAY
NIGHT INTO SUNDAY.
