NATIONAL WEATHER SERVICE CLEVELAND OH

.SYNOPSIS...
HIGH PRESSURE WILL BUILD NORTHEAST UP THE APPALACHIAN MOUNTAINS
THROUGH WEDNESDAY NIGHT AND OFF THE EAST COAST BY THURSDAY NIGHT. A
WARM FRONT WILL LIFT NORTHEAST ACROSS THE AREA THURSDAY FOLLOWED BY
A COLD FRONT FRIDAY EVENING. HIGH PRESSURE WILL BUILD SOUTHEAST
ACROSS THE REGION INTO THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
COLD FRONT WILL SWEEP EAST OF THE AREA THIS EVENING. WARM AIR MASS
ALONG WITH DEEP MOISTURE AHEAD OF THE FRONT WILL BE PUSHED EAST AND
OUT OF THE AREA. THIS WILL SET UP A DRYING TREND AS HIGH PRESSURE
BUILDS NORTHEAST UP THE APPALACHIAN MOUNTAIN CHAIN.

ROUND OF SHRA/TSRA IN THE NW COUNTIES APPEARS TO HAVE MAXED OUT. IN
GENERAL EXPECT THIS BAND OF ACTIVITY TO MOVE INTO THE CENTRAL PART
OF THE CWA WHILE GRADUALLY DISSIPATING AS NIGHTFALL OCCURS.

CLOUD COVER WILL CONTINUE TO DECREASE FROM WEST TO EAST DURING THE
NIGHT. THIS ALONG WITH LIGHT WINDS SHOULD ALLOW SOME FOG TO FORM
OVER THE INLAND AREAS THE SECOND HALF OF THE NIGHT.

WEAK COLD ADVECTION MAY NOT BE STRONG ENOUGH TO BRING IN THE DRIER
AIR AS QUICK AS THOUGHT SO WILL SLIGHTLY INCREASE LOWS OVER THE
INLAND EAST.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY NIGHT/...
BROAD UPPER LEVEL TROUGH WILL MOVE EAST OF THE AREA OVERNIGHT
SETTING UP A ZONAL FLOW ACROSS THE COUNTRY ONCE AGAIN. SURFACE HIGH
WILL BUILD NORTHEAST AND THEN EAST OF THE AREA BY WEDNESDAY NIGHT.
WARM AIR ADVECTION WILL RESUME ON THURSDAY WITH A PRETTY GOOD SURGE
OF WARM AIR RACING NORTHEAST INTO THE FORECAST AREA. 850 MB
TEMPERATURES RISE FROM 16C WEDNESDAY NIGHT TO 20C BY FRIDAY.
INCREASED DEW POINT AIR WILL RETURN AND BRING WITH IT HIGHER
HUMIDITIES ON FRIDAY.

COLD FRONT IS EXPECTED TO MOVE EAST ACROSS THE REGION FRIDAY
EVENING. CONVECTION IS EXPECTED TO REMAIN ASSOCIATED WITH THE COLD
FRONT FRIDAY AFTERNOON INTO FRIDAY NIGHT. OTHERWISE...NO MAJOR
THREAT FOR SHOWERS AND THUNDERSTORMS THROUGH THE EXTENDED PERIOD
UNTIL FRIDAY AFTERNOON. WILL HAVE TO KEEP AN EYE ON THE COLD FRONT
FRIDAY FOR SEVERE POTENTIAL DUE TO IDEAL TIMING IN THE HEAT OF THE
DAY.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
A SURFACE COLD FRONT WILL BE JUST ABOUT OUT OF THE AREA AT DAYBREAK
SATURDAY.  THERE COULD BE A FEW SHOWERS ALONG AND BEHIND THE FRONT
BUT RAPID DRYING WILL OCCUR DURING THE AFTERNOON.  READINGS NEXT
WEEKEND WILL BE BACK BELOW NORMAL WITH LOWS MONDAY MORNING POSSIBLY
GETTING INTO THE 40S.  SUNDAY WILL BE A PLEASANT DAY WITH ABUNDANT
SUNSHINE.  THE FALL LIKE WEATHER WILL CONTINUE ON MONDAY.  THE
SURFACE HIGH RESPONSIBLE FOR THE QUIET WEATHER WILL EVENTUALLY MOVE
OFF TO THE EAST ON TUESDAY ALLOWING WARMER SOUTHERLY FLOW TO
RETURN.  EXPECT TEMPS TUESDAY TO AVERAGE NEAR NORMAL.  PRECIP
CHANCES SHOULD HOLD OFF TILL JUST AFTER THE PERIOD ENDS.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
THE COLD FRONT WILL SAG ACROSS THE AREA THIS EVENING WITH A FEW
MORE SHOWERS THAT MAY PRODUCE BRIEF MVFR CONDITIONS. THE DRIER AIR
WILL BE SLOW TO FILTER IN AND THE WIND WILL BECOME LIGHT AND FOG
IS LIKELY IN MANY AREAS BY DAYBREAK. STRATUS IS ALSO POSSIBLE...
MAINLY AT INLAND SITES AND IFR CONDITIONS MAY OCCUR FOR SEVERAL
HOURS INTO MID MORNING. THE FOG AND STRATUS SHOULD

A SURFACE COLD FRONT WILL MOVE EAST OF THE LAKE BY EARLY THIS
EVENING.  LINGERING SHOWERS OVER THE LAKE WILL ALSO BE GONE BY THAT
TIME.  EXPECT THE FLOW TO BECOME WESTERLY BEHIND THE FRONT AND THEN
LIGHT AND VARIABLE OVERNIGHT.  LIGHT FLOW WILL THEN CONTINUE
WEDNESDAY WITH SOUTHERLY FLOW DEVELOPING ON THURSDAY AS A SURFACE
RIDGE PUSHES EAST OF THE LAKE.  SOUTH TO SOUTHWEST FLOW WILL THEN
GRADUALLY INCREASE AHEAD OF A COLD FRONT THAT WILL DROP SOUTH ACROSS
THE LAKE EARLY SATURDAY.  MORE PRECIP IS LIKELY WITH THIS FRONT WITH
THE FLOW BECOMING NORTH BEHIND IT.  DO NOT THINK SPEEDS WILL BE
STRONG ENOUGH FOR SMALL CRAFT HEADLINES.  NORTHERLY FLOW WILL
CONTINUE THROUGH SUNDAY.  SPEEDS MOST IF NOT THE ENTIRE PERIOD WILL
