AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
326 PM EDT TUE OCT 19 2010

.SYNOPSIS...
HIGH PRESSURE WILL MOVE EAST ACROSS THE OHIO VALLEY TONIGHT. A COLD
FRONT WILL MOVE EAST ACROSS THE AREA WEDNESDAY NIGHT INTO THURSDAY
MORNING. ANOTHER AREA OF HIGH PRESSURE WILL BUILD EAST INTO THE
REGION BEHIND THE COLD FRONT THURSDAY NIGHT INTO FRIDAY.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
A LOT OF DIURNAL CLOUDINESS CONTINUES TO DISSIPATE OVER THE EXTREME
EAST AND FEW CUMULUS OVER THE EXTREME WEST WILL START TO DISSIPATE
TOWARD SUN DOWN. I ANTICIPATE MOST OF THE AREA SHOULD SEE CLEAR
SKIES DURING THE NIGHT AND ALLOW FOR SOME GOOD RADIATIONAL COOLING
TO TAKE PLACE. LATEST SATELLITE SHOWS SOME HIGH CLOUDS SPREADING
SOUTHEAST TOWARD THE REGION BUT I ANTICIPATE THIS CLOUD COVER SHOULD
BE THIN.

THE COOL AIR IN PLACE ALONG WITH THE RADIATIONAL COOLING TAKING
PLACE...I ANTICIPATE TEMPERATURES SHOULD GET PRETTY CHILLY IN THE
EXTREME EAST...ESPECIALLY IN THE VALLEYS. AFTER COORDINATION WITH
SURROUNDING OFFICES...DECIDED TO GO WITH A FREEZE WARNING IN
CRAWFORD COUNTY PENNSYLVANIA AND FROST ADVISORIES FROM SOUTHERN ERIE
COUNTY PENNSYLVANIA SOUTHWEST INTO KNOX COUNTY.

AREAS NEAR THE LAKE SHOULD REMAIN UNDER SOME INFLUENCE OF THE LAKE
IN VERY LIGHT WESTERLY FLOW. WESTERN HALF OF THE AREA SHOULD START
TO SEE SOME WEAK WARM AIR ADVECTION TAKING PLACE AFTER MIDNIGHT AND
THIS SHOULD MINIMIZE THREAT FOR FROST.

TEMPERATURES EXPECTED TO BE IN THE MIDDLE 30S MOST AREAS EXCEPT
LOWER 30S...SAY AROUND 32 IN CRAWFORD COUNTY PENNSYLVANIA. LOWER 40S
EXPECTED NEAR THE LAKE IN THE NORTHEAST.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH SATURDAY NIGHT/...
HIGH PRESSURE IS EXPECTED TO BE THE DOMINANT WEATHER FEATURE ON
WEDNESDAY AS IT MOVES BY ACROSS THE OHIO VALLEY.

A COLD FRONT IS FORECAST TO MOVE SOUTHEAST TOWARD THE AREA WEDNESDAY
NIGHT INTO THURSDAY MORNING. SOME ASSOCIATED MOISTURE WILL ALSO
STREAM INTO THE REGION ALONG WITH THE COLD FRONT. MUCH COLDER AIR
WILL FOLLOW THE FRONT INTO THURSDAY AND THURSDAY NIGHT. 850 MB
TEMPERATURES DIP TO ABOUT -4 IN THE NORTHEAST. TEMPERATURES ALOFT
AND AT THE SURFACE SHOULD BE COLD ENOUGH TO ALLOW SOME WET SNOW TO
MIX IN WITH THE RAIN THURSDAY NIGHT AFTER MIDNIGHT.  I DONT
ANTICIPATE THERE WILL BE ENOUGH SNOW TO ACCUMULATE IN THE HIGHER
ELEVATIONS.

AREAS TO THE SOUTH AND WEST SHOULD REMAIN DRY THROUGH THIS PERIOD AS
BEST MOISTURE AND ASSOCIATED DYNAMICS MOVE OVER THE EASTERN HALF OF
THE AREA.

HIGH PRESSURE FINALLY BUILDS IN FOR FRIDAY AFTERNOON INTO FRIDAY
NIGHT BUT WILL BE SHORT LIVED. HIGH PRESSURE MOVES QUICKLY EAST
ALLOWING SOME WARM AIR ADVECTION TO TAKE PLACE FRIDAY AFTERNOON INTO
SATURDAY. HOWEVER...WITH THE WARM AIR COMES ANOTHER SHOT OF MOISTURE
OUT OF THE SOUTHWEST IN ASSOCIATION WITH A STORM SYSTEM MOVING
NORTHEAST. AS STORM SYSTEM REACHES SOUTHERN GREAT LAKES
REGION...GULF OF MOISTURE STARTS TO OPEN UP ALLOWING MOISTURE TO
STREAM NORTH INTO THE REGION. THIS WILL SET UP A WET PATTERN INTO
THE WEEKEND.

TEMPERATURES THROUGH THE PERIOD WILL BE HOVERING AROUND NORMAL WITH
A WARM UP BACK TO THE MIDDLE AND UPPER 60S FOR THE WEEKEND IN THE
SOUTH TO SOUTHWEST FLOW. OVERNIGHT LOWS BEGIN TO MODERATE A BIT
TOMORROW NIGHT BUT THEN PLUNGE BACK INTO THE 30S TO LOWER 40S AS
COLD AIR ADVECTION TAKES PLACE BEHIND THE COLD FRONT.

&&

.LONG TERM /SUNDAY THROUGH TUESDAY/...
A FRONTAL SYSTEM WILL BE IN THE AREA ON SUNDAY AND WILL
BRING A CHANCE OF SHOWERS SUNDAY AND MONDAY. ANOTHER MUCH STRONGER
FRONTAL SYSTEM WILL APPROACH ON TUESDAY AND BRING MORE SHOWERS.
TEMPERATURES TO AVERAGE NEAR THE SEASONAL NORMALS.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
WEAK HIGH PRESSURE WITH DRYING CONDITIONS MOVING INTO THE
FORECAST AREA FOR THIS AFTERNOON AND TONIGHT WITH SOME SCATTERED
CUMULUS CLOUDS EXPECTED. FOR MY EXTREME EASTERN TAF SITES...SOME
CLOUD COVER STILL HOLDING-ON DUE TO A WEAK SHORT WAVE THAT SHOULD
BE PULLING-OUT LATER THIS AFTERNOON AND EVENING.

FOR TONIGHT SOME CIRRUS CLOUDS WILL BE LURKING AROUND THE AREA
BUT IT SHOULD BE GENERALLY DRY. ON WEDNESDAY THE HIGH PRESSURE
SHOULD STILL DOMINATE WITH VFR CONDITIONS.

WINDS WESTERLY THIS AFTERNOON 10 TO 15 KNOTS.

.OUTLOOK...NON VFR POSSIBLE THURSDAY ESPECIALLY NORTHEAST OHIO AND
NORTHWEST PA. NON VFR POSSIBLE ACROSS THE AREA ON SATURDAY.

&&

.MARINE...
WITH WEST TO SOUTHWEST FLOW OF 10 TO 15 KNOTS EXPECT CHOPPY
CONDITIONS...BUT BELOW SMALL CRAFT ADVISORY CRITERIA.  BY WEDNESDAY
AFTERNOON/EVENING IT LOOKS LIKE A MUCH STRONGER COLD FRONT WILL
SWEEP ACROSS THE LAKE. SMALL CRAFT ADVISORY WILL BE NEEDED
TOMORROW.  SOUTHWEST WINDS WILL INCREASE TO AT LEAST 15 TO 25 AHEAD
OF THE APPROACHING COLD FRONT.  WIND SPEEDS WILL HIT 30 KNOTS BY
FROPA TOWARD WEDNESDAY EVENING.  VERY COLD ARI BEHIND THE FRONT AS
850 TEMPS DIP TO 0C BY 12Z THURSDAY.  CONDITIONS IMPROVE FRIDAY AS
HIGH PRESSURE MOVES ACROSS THE OHIO VALLEY/LOWER GREAT LAKES.

&&
