AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
633 PM EDT FRI JUL 3 2015

.SYNOPSIS...
WEAK HIGH PRESSURE WILL REMAIN OVER THE SOUTHERN GREAT LAKES INTO
SUNDAY THEN SHIFT EAST MONDAY. MEANWHILE WEAK LOW PRESSURE OVER
THE OHIO VALLEY WILL MOVE OFF THE MID ATLANTIC COAST. A COLD
FRONT WILL SLOWLY MOVE SOUTHEAST ACROSS THE AREA LATE TUESDAY.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
SHOWERS MOVING NORTHEAST ACROSS THE SOUTHEASTERN PORTION OF THE
FORECAST AREA THIS EVENING. MOST OF IT IS NOT REACHING THE GROUND
AND IT APPEARS TO BE WEAKENING WITH TIME AS THE SUN BEGINS TO DROP
IN THE SKY. PRECIPITATION HAS A LOT OF DRY AIR TO OVERCOME AND I
THINK WE SHOULD SEE DIMINISHING PRECIPITATION THREAT AS THE
EVENING PROGRESSES. OTHERWISE...TO THE WEST EXPECTING SOME CLOUDS
EARLY GIVING WAY TO SOME CLEARING IN THE EXTREME WEST OVERNIGHT.

UPDATED HOURLY TEMPERATURES TO REFLECT TRENDS.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY NIGHT/...
THERE COULD BE A FEW LIGHT LINGERING SHOWERS IN THE EASTERN EDGE
OF THE FORECAST AREA SATURDAY MORNING OTHERWISE A DRY WEEKEND IS
EXPECTED AS THE UPPER TROUGH AXIS FINALLY SHIFTS EAST AND A SHORT
WAVE RIDGE BRIEFLY BUILDS OVER THE REGION SATURDAY NIGHT AND
SUNDAY. DRIER AND MORE STABLE AIR SHOULD ENSURE A TRANQUIL EVENING
FOR VIEWING FIREWORKS DISPLAYS.

THE FORECAST FOR MONDAY AND MONDAY NIGHT IS MORE UNCERTAIN AS A
SHORT WAVE TROUGH IN THE TENN VALLEY AMPLIFIES AND SHIFTS NORTH
INTO THE CENTRAL APPALACHIANS. ONCE AGAIN THE SOUTHEAST COUNTIES
MAY JUST GET BRUSHED BY A FEW LIGHT SHOWERS ON THE NORTHERN EDGE
OF THIS SYSTEM.

850 MB TEMPERATURES WILL CONTINUE TO WARM TO NEAR SEASONAL VALUES
ON MONDAY AND REACH NEAR 16C WHICH WILL LIKELY PRODUCE HIGH
TEMPERATURES IN THE MID 80S.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
ENOUGH MOISTURE MAY LINGER IN THE EASTERN PORTION OF THE AREA ON
TUESDAY MORNING TO MAKE IT WORTH HAVING A LOW POP IN THE FORECAST
OUT AHEAD OF THE APPROACHING COLD FRONT. THIS COLD FRONT WILL PUSH
INTO NORTHWEST OHIO ON TUESDAY AFTERNOON AS A TROUGH MOVES ACROSS
THE UPPER GREAT LAKES. BEST UPPER LEVEL FORCING PASSES WELL TO THE
NORTH SO WILL LEAVE POPS IN THE CHANCE CATEGORY FOR TUESDAY
AFTERNOON AND NIGHT.

LONG RANGE MODELS GENERALLY SHOW THE FRONT PUSHING SOUTH OF THE AREA
BY WEDNESDAY BUT SUSPECT THE FRONT WILL STRUGGLE TO CLEAR THE AREA
GIVEN THE FLOW ALOFT BECOMES SOMEWHAT ZONAL BETWEEN THE TROUGH OVER
CANADA AND RIDGE OVER THE SOUTHEASTERN STATES. ALTHOUGH MODELS
STRUGGLE WITH TIMING...MANY OF THEM SHOW ENERGY MOVING ALONG THE
STALLED BOUNDARY THROUGH MID-WEEK WHICH MAY CAUSE ADDITIONAL CHANCES
OF SHOWERS/THUNDERSTORMS. THE CANADIAN IS THE FASTEST TO BRING
PRECIPITATION BACK TO THE AREA BY WEDNESDAY NIGHT. GIVEN THE
UNCERTAINTY IN WHERE THE FRONT WILL RESIDE...WILL HOLD ONTO CHANCE
POPS THROUGH THURSDAY. TEMPERATURES THROUGH THE EXTENDED WILL BE
NEAR TO SLIGHTLY BELOW NORMAL.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
VFR CONDITIONS IN PLACE ACROSS THE AREA WILL CONTINUE INTO TONIGHT.
SCATTERED LIGHT SHOWERS EXTENDING EASTWARD FROM COLUMBUS WILL
CONTINUE TO ADVANCE NE TOWARDS CAK/YNG THIS AFTERNOON AND EVENING.
THESE LIGHT SHOWERS MAY SNEAK INTO MFD/CAK/YNG THIS EVENING BUT WILL
BE BRIEF AND LIGHT IF THEY IMPACT ANY TERMINALS WITH MINIMAL RESTRICTION
TO CEILING/VISIBILITY. OTHERWISE DID INCLUDE A PERIOD OF MVFR
VISIBILITIES AT CAK/YNG LATE TONIGHT...IMPROVING BY 13Z. EAST TO
NORTHEAST WINDS OF 10 KNOTS OR LEFT WILL SHIFT TO THE NORTH
OVERNIGHT.

OUTLOOK...NON VFR CONDITIONS POSSIBLE TUESDAY IN SHOWERS AND
THUNDERSTORMS.

&&

.MARINE...
GENERALLY GOOD MARINE CONDITIONS WILL CONTINUE THROUGH MONDAY WITH
WINDS OF 12 KNOTS OR LESS. HIGH PRESSURE OVERHEAD WILL WEAKEN
SLIGHTLY TONIGHT AS LOW PRESSURE OVER THE OHIO VALLEY MOVES
NORTHEAST INTO WESTERN PENNSYLVANIA. ONSHORE FLOW NEAR 10 KNOTS WILL
MAINTAIN 1-2 FOOT WAVES THIS EVENING. THE HIGH WILL STRENGTHEN AGAIN
ON SATURDAY AND REMAIN IN CONTROL UNTIL EVENTUALLY SHIFTING EAST ON
MONDAY. A COLD FRONT WILL MOVE SOUTHEAST ACROSS LAKE ERIE ON
TUESDAY.

&&
