AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
107 AM EDT THU MAY 28 2015

.SYNOPSIS...
A WEAKENING COLD FRONT WILL MOVE TO THE EAST THIS EVENING. WEAK HIGH
PRESSURE WILL BRIEFLY BE OVER THE AREA THURSDAY BUT WILL MOVE OFF
THE NEW ENGLAND COAST EARLY FRIDAY AS LOW PRESSURE MOVES THROUGH
THE CENTRAL GREAT LAKES.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
THE LAST OF THE CONVECTION WILL CONTINUE TO PUSH OFF TO THE EAST
THROUGH MIDNIGHT. 500 MB TROF AXIS WILL CLEAR THE AREA BY MID
MORNING AND CLOUDS WILL DECREASE THROUGH LATE MORNING...ESPECIALLY
IN THE WEST.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY NIGHT/...
THURSDAY HIGH PRESSURE WILL BE IN CONTROL FOR THE DAY WITH FAIRLY
DRY AIR IN PLACE. WILL GO WITH PARTLY CLOUDY/MOSTLY SUNNY FOR THE
DAY. THURSDAY NIGHT MOISTURE WILL RETURN FROM THE SOUTH AS THE
HIGH MOVES EAST. CONCERNED ABOUT SHOWERS DEVELOPING MAINLY EAST
HALF. FRIDAY A COLD FRONT WILL APPROACH FROM THE
NORTHWEST..REACHING THE CENTRAL LAKES BY 00Z SATURDAY. SATURDAY
THE COLD FRONT WILL MOVE THROUGH. LIKELY POPS REASONABLE THROUGH
THE FIRST HALF OF SATURDAY NIGHT. POPS WILL TAPER FROM NORTHWEST
TO SOUTHEAST LATE SATURDAY NIGHT AND SUNDAY.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
THE BIGGEST ISSUE IN THE EXTENDED PORTION OF THE FORECAST IS HOW FAR
SOUTH THE FRONT WILL SAG ON SUNDAY AND HOW QUICKLY IT COMES BACK
NORTH. WILL DECREASE THE CHANCE OF SHOWERS ON SUNDAY. A LOT OF
TIMES THE MODELS ARE OVER DONE ON HOW MUCH PRECIP ACTUALLY OCCURS IN
THESE PATTERNS. WILL KEEP A LOW POP CHANCE (15-30 POP) EARLY NEXT
WEEK UNTIL WE CAN SEE A BETTER TREND IN THE MODELS AND GRADUALLY
INCREASE TEMPERATURES BACK UP ABOVE NORMAL BY MID WEEK.

&&
