AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
105 AM EDT THU APR 2 2015

.SYNOPSIS...
HIGH PRESSURE CENTERED OVER THE EASTERN GREAT LAKES WILL CONTINUE
TO MOVE EAST OVERNIGHT. AN AREA OF LOW PRESSURE WILL MOVE ACROSS
ONTARIO ON THURSDAY. A WARM FRONT FROM THE LOW WILL LIFT NORTH
ACROSS THE AREA TOMORROW AND WILL BE FOLLOWED BY A COLD FRONT
DURING THE EVENING. THE COLD FRONT WILL BECOME NEARLY STATIONARY
NEAR THE OHIO RIVER FRIDAY AS LOW PRESSURE MOVES NORTHEAST ALONG
THE BOUNDARY. HIGH PRESSURE WILL TRY TO BUILD OVER THE REGION
FROM THE SOUTH THIS WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
THE FIRST FEW WISPS OF CIRRUS ARE STARTING TO MAKE THEIR WAY SW INTO
THE CWA. FOR THE TIME BEING THE CIRRUS WILL REMAIN SCATTERED BUT
DURING THE SECOND HALF OF THE NIGHT THE CIRRUS DROPPING IN FROM THE
WNW AND THE CIRRUS TO THE SW ARE EXPECTED TO MERGE OVER THE AREA.
DUE TO COLLABORATION WILL ONLY ALLOW SKY COVER TO RAMP UP TO 30 TO
40% IN THE SE AND EAST.


HRRR AND RUC STILL HOLDING OFF PRECIP NEARING THE WEST UNTIL AFTER
12Z SO CONTINUE TO KEEP THE FORECAST DRY THE REST OF TONIGHT. LOWS
WILL PROBABLY OCCUR BY 06Z THEN TEMPS MAY START TO DRIFT UP A FEW
DEGREES THROUGH 12Z AS MORE HIGH CLOUDS ARRIVE AND WINDS FROM THE
SOUTH START TO INCREASE.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY NIGHT/...
THURSDAY WILL BE A WARM AND PROBABLY BUSY DAY. SHOWERS WILL SPREAD
EAST ACROSS THE WESTERN END OF THE AREA DURING THE MORNING HOURS.
AREAS EAST OF I-71 SHOULD REMAIN DRY THROUGH 18Z. MU CAPES GET TO
AROUND 500 J/KG IN THE AFTERNOON WITH BULK SHEAR VALUES AROUND 30
KNOTS. STILL EXPECTING A LINE OF SHOWERS WITH EMBEDDED THUNDER TO
DEVELOP TO THE WEST OF THE AREA DURING THE AFTERNOON AND THEN MOVE
INTO NW OHIO LATE IN THE DAY. MOST AREAS WILL HEAR THUNDER FOR THE
FIRST TIME THIS SPRING. WILL NEED HIGH PRECIP CHANCES ALL AREAS BY
LATE IN THE DAY AND AGAIN THURSDAY NIGHT. QPF AMOUNTS IN THE HALF
INCH TO THREE QUARTERS OF AN INCH RANGE ARE LIKELY. THE SURFACE
COLD FRONT RESPONSIBLE FOR THIS PRECIP WILL STALL TO THE SOUTH OF
THE AREA ON FRIDAY. ALL OF THE NEW GUIDANCE CONTINUES TO SHOW A
WAVE DEVELOPING ALONG THE FRONT. THIS WILL PUSH THE PRECIP BACK
NORTH ACROSS THE AREA LATE FRIDAY. SOUTHERN AREAS MAY NEVER GET
OUT OF THE PRECIP FRIDAY BUT A DRY PERIOD IS LIKELY NEAR LAKE
ERIE. MORE RAIN IS LIKELY FRIDAY NIGHT WITH THE SHOWERS QUICKLY
TAPERING OFF FROM WEST TO EAST EARLY SATURDAY. HIGH PRESSURE WILL
THEN START TO BUILD IN FROM THE SOUTHWEST.

AS FAR AS THE SEVERE WEATHER POTENTIAL GOES FOR TOMORROW. THINK
THERE COULD BE A FEW STORMS THAT APPROACH SEVERE LIMITS. HAVE SOME
CONCERN THAT THERE WILL BE A LOT OF CLOUDS AROUND TOMORROW WHICH
COULD LIMIT THE DESTABILIZATION. THE LATEST OUTLOOK HAS PART OF
THE AREA IN THE MARGINAL CATEGORY AND THIS SEEMS REASONABLE. WILL
PUT A MENTION IN THE HWO.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
SUNDAY COULD WIND UP BEING A MIXED WEATHER DEPENDING ON WHERE THE
STATIONARY FRONTAL BOUNDARY LINGERS. CURRENTLY...THE FRONT IS
PROGGED TO BE OVER LAKE ERIE INTO NORTHWEST PENNSYLVANIA BY SUNDAY
MORNING. THE FRONT LINGERS OVER THE AREA THROUGH TUESDAY UNTIL A LOW
PRESSURE SYSTEM APPROACHES FROM THE WEST. STATIONARY FRONT WILL
BECOME A WARM FRONT AND LIFT NORTH OF THE AREA BY TUESDAY MORNING.
THIS SHOULD KEEP THE WARM AIR ADVECTION IN THE AREA DURING THE DAY
TUESDAY. THE LOW WILL MOVE EAST OF THE AREA TUESDAY NIGHT INTO
WEDNESDAY DRAGGING A COLD FRONT ACROSS THE AREA. AIR MASS BEHIND THE
FRONT IS NOT EXPECTED TO BE ALL THAT COLD. HIGH PRESSURE WILL
QUICKLY BUILD EAST ACROSS THE NORTHERN GREAT LAKES BY THURSDAY.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
WARM FRONT JUST SW OF STL WILL MOVE NE ACROSS THE FORECAST AREA
LATE THIS MORNING. WILL SEE SOME SCATTERED SHOWERS WITH THE FRONT
BUT HAVE DOUBTS AS TO HOW WIDESPREAD IT WILL BE. COLD FRONT NOW
ACROSS WISCONSIN...WILL MOVE ACROSS THE AREA TONIGHT. AHEAD OF THE
FRONT SOUTH WINDS WILL INCREASE TO 20 TO 30 KNOTS THIS AFTERNOON.
BEHIND THE FRONT UPWARDS OF A HALF INCH OF RAIN POSSIBLE TOMORROW
NIGHT WITH IFR CONDITIONS.

THE WARM AIR ADVECTION PATTERN.  AS COLD FRONT SLIPS EAST ACROSS THE
LAKE THURSDAY NIGHT...WINDS DIMINISH FAIRLY QUICKLY. NORTHWEST FLOW
