AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
422 AM EST TUE MAR 3 2015

.SYNOPSIS...
AN AREA OF LOW PRESSURE WILL MOVE ACROSS THE CENTRAL GREAT LAKES
TODAY AND A COLD FRONT WILL MOVE ACROSS THE REGION TONIGHT. THE
FRONT WILL THEN STALL SOUTH OF THE AREA AS ANOTHER LOW PRESSURE
SYSTEM TRACKS ALONG IT FOR WEDNESDAY AFTERNOON AND NIGHT. HIGH
PRESSURE RETURNS TO THE AREA BY FRIDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE PRECIPITATION WILL APPEAR ALOFT FIRST AND THEN START REACHING
THE GROUND AFTER DAYBREAK. IT WILL START AS SNOW AND THEN GO TO
SLEET AND FREEZING RAIN AND THEN RAIN. THE TIMING OF GOING TO RAIN
IS IN QUESTION. THE HOURLY TEMPERATURES ARE TOUGH. THE GUIDANCE IS
NOT DOING GOOD AT THIS TIME...TRIED TO ADJUST THEM. WILL TRY TO
HAVE THE ADVISORY START WHEN THE SNOW STARTS. AT LOCATIONS WELL
INLAND THE TRANSITION TO SLEET AND FREEZING RAIN WILL BE QUICKER
THAN IN THE NORTH...THUS LESS SNOWFALL. MADE MINOR CHANGES TO THE
ADVISORY. EXTENDED THE EXPIRATION TIME OVER NE OH AS THE GROUND IS
COLD AND THE DEW POINTS ARE LOW...IT WILL TAKE TIME TO FOR THE
FREEZING RAIN TO QUIT FREEZING. THE AMOUNTS WILL NOT BE THAT HEAVY
BUT UNTREATED ROADS AND SIDEWALKS WILL BE SLIPPERY.

THE WARMEST TEMPERATURES TODAY WILL OCCUR CLOSE TO DARK.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/...
TEMPERATURES WILL BE MILD TO START AND THEN START DECREASING AFTER
THE FRONT MOVES THROUGH.

THE PRECIPITATION WILL DECREASE FROM NORTH TO SOUTH TONIGHT AND
AFTER MIDNIGHT CHANGE BACK TO SNOW AFTER THE FRONT MOVES THROUGH. NOT
EXPECTING MUCH SNOW ACCUMULATION.

WEDNESDAY AFTERNOON AND NIGHT GETS INTERESTING MAINLY FOR
LOCATIONS SOUTH OF ROUTE 30 AS A WAVE DEVELOPS ON THE FRONT THAT
WILL MOVE THROUGH TONIGHT. RAISED POPS SOME BUT IT IS NOT TOTALLY
CLEAR CUT HOW FAR NORTH THE SNOW WILL GET. THIS WILL HAVE TO BE
MONITORED CLOSELY.

FOR THURSDAY SOME SNOW SHOWERS WILL LINGER MAINLY IN THE EAST AS
THE RIDGE WILL BE BUILDING IN ALONG WITH DRIER AIR BUT THE LAKE
AND 850 MB TEMPERATURE DIFFERENCE WILL BE OVER 20C.

DRY WEATHER THURSDAY NIGHT THROUGH FRIDAY NIGHT AS A RIDGE WILL BE
BUILDING IN.

EXPECTING THE RAINFALL AMOUNTS TO BE UNDER HALF AN INCH AND WITH
SUCH A BRIEF WARM UP SOME SNOW MELT WILL OCCUR SO ONLY EXPECTING
SOME PONDING OF WATER ON ROADS AND IN LOW LYING AREAS. SOME
MOVEMENT OF THE ICE MAY OCCUR IN THE NARROWER RIVERS AND
STREAMS...HOWEVER...AT THIS TIME NOT EXPECTING MUCH IN THE WAY OF
ICE JAM FLOODING. THIS SITUATION WILL BE MONITORED.

&&

.LONG TERM /SATURDAY THROUGH MONDAY/...
THE MODELS SHOW ENOUGH OF A BAND OF MOISTURE SAT INTO SAT NIGHT WITH
A WEAKENING COLD FRONT TO ALLOW FOR SOME SCT PRECIP AND TEMPS MAY
STAY JUST COLD ENOUGH FOR MOSTLY SNOW TO OCCUR. HIGH PRESSURE BUILDS
IN FOR SUN BUT YET ANOTHER COLD FRONT IS SHOWN MOVING IN BY MON
MORNING TO PROVIDE ANOTHER CHANCE FOR SNOW LATE SUN NIGHT AND MON.
HIGH PRESSURE REBUILDS OVER THE AREA MON NIGHT BUT THE MODELS STILL
SHOW GOOD MOISTURE NEAR LAKE ERIE SO WILL CARRY SMALL CHC POPS THERE.

TEMPS WILL CONTINUE TO RUN BELOW NORMAL.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
LITTLE CHANGE WITH WHAT IS EXPECTED OF THE PRECIPITATION COMING
OUR WAY FOR TUESDAY. VFR FOR THE OVERNIGHT WITH CONDITIONS RAPIDLY
DETERIORATING IN THE MORNING. INITIAL PRECIPITATION TO OVERSPREAD
THE AREA WILL BE IN THE FORM OF LIGHT/VFR-MVFR SNOW. THERE WILL
BE A TRANSITION ZONE WHERE FZRA OR PL WILL BE POSSIBLE -
MVFR/ISOLATED IFR. FINALLY ALL TAF SITES ARE EXPECTED TO TRANSITION
TO PLAIN RAIN AND IFR CONDITIONS BY MID/LATE AFTERNOON AS
TEMPERATURES RISE ABOVE FREEZING. EAST- SOUTHEAST WINDS SHIFT TO
THE SOUTH AND PICK UP AS THE RAIN ARRIVES. LOW LEVEL WIND SHEAR TO
CONTEND WITH TOO LATE IN THE AFTERNOON GOING INTO THE EVENING.
COLD FRONT CROSSES IN THE EVENING WITH RAIN LINGERING FOR THE
EASTERN SITES. GUSTS WILL CONTINUE INTO THE EVENING AS WELL.

.OUTLOOK...NON-VFR CONTINUING THROUGH WEDNESDAY NIGHT AND
LINGERING INTO TUESDAY ACROSS FAR NE OH/NW PA. NON VFR POSSIBLE
SATURDAY.

&&

.MARINE...
SOUTH WINDS SHOULD INCREASE TO ABOUT 20 TO 30 KNOTS BY EVENING WHILE
TURNING SW THEN W OVERNIGHT WITH THE PASSAGE OF THE NEXT ARCTIC
FRONT. HIGH PRESSURE WILL TAKE UNTIL THU NIGHT TO MOVE ACROSS OH SO
