AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
159 PM EDT SAT MAY 17 2014

.SYNOPSIS...
HIGH PRESSURE WILL BUILD EAST ACROSS THE LOCAL AREA
THROUGH TUESDAY MORNING. A WARM FRONT WILL LIFT NORTH ACROSS THE
AREA ON TUESDAY. MEANWHILE...LOW PRESSURE WILL MOVE NORTHEAST INTO
THE WESTERN GREAT LAKES AND THEN DRIFT EAST INTO SOUTHERN ONTARIO
CANADA DRAGGING A COLD FRONT ACROSS THE REGION WEDNESDAY EVENING.
HIGH PRESSURE WILL BUILD SOUTH INTO THE GREAT LAKES REGION THROUGH
THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE DESTABILIZATION FROM THE UPPER TROUGH ALONG WITH WEAK
DISTURBANCES MOVING THRU THE AREA WILL PROVIDE THE FORCING FOR SCT
SHRA TODAY. AS THE SUN STARTS TO SET AND TEMPS COOL EVEN MORE THE
SCT SHRA SHOULD START TO DISSIPATE. HAVE BUMPED UP POPS TO LIKELY
FOR THE CLE AREA THIS MORNING TO ADJUST FOR CURRENT AND IMMINENT
CONDITIONS BASED ON RADAR.

TEMPERATURES WILL BE SIMILAR TO YESTERDAY AS THE COLD AIR ADVECTION
CONTINUES. MUCH OF THE AREA SHOULD ONLY SEE HIGHS IN THE LOW TO MID
50S WITH THE COOLER READINGS GENERALLY ALONG THE LAKESHORE FROM
CLEVELAND EAST.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/...
UPPER LEVEL TROUGH EVENTUALLY BEGINS TO SHIFT EAST TONIGHT AND
THIS WILL ALLOW SURFACE HIGH PRESSURE TO BUILD ACROSS THE REGION.
MODELS ARE INDICATING THAT THE LOW LEVEL MOISTURE WILL BEGIN TO
PULL OUT TO THE EAST LATE THIS AFTERNOON INTO THE EVENING HOURS.
THINKING RIGHT NOW IS THAT SKIES SHOULD CLEAR OUT ENOUGH ALONG
WITH WINDS DIMINISHING TO LIGHT AND VARIABLE AS WE DECOUPLE TO
ALLOW TEMPERATURES TO DROP INTO THE MIDDLE TO UPPER 30S TONIGHT.
COLDEST TEMPERATURES WILL BE IN THE EAST AND IN LOW LYING AREAS.
SO...WITH THAT...WILL MENTION AREAS OF FROST IN THE EAST AWAY FROM
THE LAKE AND PATCHY FROST THE REST OF THE AREA OVERNIGHT. WILL
HOLD OFF ON ISSUING A FROST ADVISORY AT THIS TIME DUE TO THE
POTENTIAL THAT MOISTURE MAY NOT PULL OUT AS FAST AS ANTICIPATED TO
ALLOW FOR THE CLEARING SKIES.

BROAD UPPER LEVEL RIDGE OF HIGH PRESSURE WILL BEGIN TO BUILD IN
ACROSS THE AREA SUNDAY AND SURFACE HIGH WILL BE CENTERED OVER THE
LOCAL AREA. SOME WARM AIR ADVECTION WILL BEGIN TO TAKE PLACE OVER
THE WESTERN HALF OF THE AREA SUNDAY INTO SUNDAY NIGHT. WITH HIGH
OVERHEAD...WE MAY HAVE THE BEST SHOT AT DECOUPLING TO CAUSE CALM
WINDS AND EXCELLENT RADIATIONAL COOLING. WILL LIKELY NEED A FROST
ADVISORY AT THE MINIMUM ACROSS THE EAST SUNDAY NIGHT.

THE SURFACE HIGH PRESSURE CENTER REMAINS THE DOMINANT WEATHER
FEATURE THROUGH TUESDAY. A WARM FRONT IS EXPECTED TO LIFT NORTH
ACROSS THE AREA TUESDAY AFTERNOON INTO TUESDAY NIGHT. THIS SHOULD
BRING ANOTHER SURGE OF WARM AIR BACK TO THE FORECAST AREA. SOME
MOISTURE ASSOCIATED WITH THE WARM FROM COULD SNEAK IN HERE TUESDAY
NIGHT AND BRING A THREAT FOR SOME SHOWERS AND THUNDERSTORMS.
MOISTURE WILL BE LIMITED WITH THE FRONT BUT ENOUGH CONVERGENCE
COULD SUPPORT THE THREAT FOR THE PRECIPITATION ALONG WITH THE
INSTABILITY.

AS FAR AS TEMPERATURES GO...WARM AIR ADVECTION WILL GRADUALLY TAKE
PLACE ENDING THE THREAT FOR FROST ADVISORIES BY MONDAY NIGHT. A
RETURN BACK TO THE 60S AND LOWER 70S FOR HIGHS BY TUESDAY ON THE
WEST SIDE OF THE HIGH PRESSURE. WE COULD ACTUALLY BE WARMER THAN
THIS BUT WILL TREND TEMPERATURES UPWARD WITH THIS PACKAGE.

&&

.LONG TERM /WEDNESDAY THROUGH FRIDAY/...
A COLD FRONT WILL BE MOVING ACROSS THE REGION ON WEDNESDAY WITH
INCREASED LIFT ALONG AND AHEAD OF IT. MINIMAL AMOUNTS OF GULF
MOISTURE WILL FLOW INTO THE REGION AHEAD OF THE FRONT BUT THERE WILL
BE ENOUGH INSTABILITY TO MENTION THUNDERSTORMS. AN UPPER LEVEL
TROUGH WILL THEN LINGER OVER THE NORTHEASTERN US THURSDAY INTO
FRIDAY. THIS MAY BE CLOSE ENOUGH TO KEEP SLIM CHANCES OF SHOWERS
OVER THE NORTHEASTERN PORTION OF THE COUNTY WARNING AREA.

HIGHS ON WEDNESDAY WILL ALL HINGE ON THE AMOUNT OF CLOUD COVER THAT
DEVELOPS OVER THE REGION. AT THIS POINT WE SHOULD SEE ENOUGH
SUNSHINE AND AN INCREASED SOUTHERLY FLOW TO ALLOW FOR HIGHS IN THE
MIDDLE AND UPPER 70S. A FEW 80S ACROSS THE WEST AND SOUTH. COOLER IN
THE WAKE OF THE FRONT ON THURSDAY AND FRIDAY WITH HIGHS GENERALLY
WITHIN A COUPLE DEGREES OF SEASONAL AVERAGES.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
UPPER LEVEL TROUGH OVER THE AREA WITH COOL AIR HAS HELPED TRIGGER
SCATTERED SHOWERS ACROSS THE REGION. LAKE BREEZE CONVERGENCE ZONES
AWAY FROM LAKE MICHIGAN AND TO A LESSER EXTENT LAKE ERIE HAS AIDED
SHOWER DEVELOPMENT. SOME SMALL HAIL HAS BEEN REPORTED WITH SOME
HEAVIER SHOWERS. ONE AREA OVER NORTHEAST OHIO AND NW PA IS MOVING
EAST WITH A BRIEF BREAK AND ANOTHER BAND FROM CENTRAL LOWER
MICHIGAN INTO INDIANA. THIS SECOND AREA WILL MOVE INTO THE REGION
OVER THE NEXT SEVERAL HOURS. VFR CIGS EXPECTED WITH VSBY DROPPING
TO 4-6 MILES IN THE HEAVIER SHOWERS.

SHOWER ACTIVITY WILL DISSIPATE TOWARD EVENING WITH CLEARING
SHORTLY AFTER SUNSET AS THE UPPER TROUGH GRADUALLY MOVES AWAY AND
MORE STABILIZATION OF THE AIR MASS TAKES PLACE. FAIRLY LIGHT
WINDS ARE EXPECTED GENERALLY LESS THAN 10 KNOTS AS HIGH PRESSURE
SLOWLY BUILDS INTO THE AREA. PATCHY FOG MAY DEVELOP AFTER MIDNIGHT
IN LOW LYING AREAS DUE TO THE NEAR SATURATED GROUND.

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

&&

.MARINE...
AN UPPER LEVEL TROUGH WILL SLOWLY MOVE ACROSS THE REGION TODAY WITH
LIGHT WESTERLY WINDS DEVELOPING IN ITS WAKE. THE WINDS WILL REMAIN
UNDER 10 KNOTS. HIGH PRESSURE WILL BE NEAR THE SOUTH SHORE OF LAKE
ERIE ON SUNDAY WITH LIGHT WINDS EXPECTED. THESE LIGHT WINDS WILL
CONTINUE INTO TUESDAY AS HIGH PRESSURE GETS NUDGED EASTWARD. THIS
WILL ALLOW FOR INCREASING SOUTHERLY WINDS AHEAD OF A COLD FRONT THAT
WILL CROSS THE LAKE ON WEDNESDAY. SOUTH TO SOUTHWEST WINDS MAY REACH
15 KNOTS TUESDAY INTO TUESDAY NIGHT. WINDS WILL SHIFT TO THE WEST
AND NORTHWEST IN THE WAKE OF THE FRONT ON WEDNESDAY.

&&

.CLE WATCHES/WARNINGS/ADVISORIES...
OH...NONE.
PA...NONE.
