AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
329 PM EDT FRI MAY 25 2007

.SYNOPSIS...
COLD FRONT JUST ABOUT SOUTH OF THE FORECAST AREA...WEAK HIGH
PRESSURE WILL MOVE IN TONIGHT. THE FRONT WILL MOVE BACK ACROSS
THE AREA AS A WARM FRONT SATURDAY FOLLOWED BY ANOTHER COLD FRONT
SUNDAY. HIGH PRESSURE WILL MOVE ACROSS THE REGION MONDAY. ANOTHER
COLD FRONT IS EXPECTED TO MOVE EAST TO BE NEAR OHIO FRIDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
A BOUNDARY MOVED THROUGH DURING THE MORNING AND NOW THE COLD FRONT IS
MOVING INTO NORTHWEST OHIO. THE STORMS ARE MORE PULSING AT THIS
TIME...NOT ENOUGH SHEAR TO KEEP THEM GOING. THE MODELS TRY TO
INCREASE THE MOISTURE LATER TONIGHT. THIS SEEMED REASONABLE
EARLIER...NOW ON THE EDGE. THE AIRMASS GETS MORE STABLE SO WILL GO
LIKELY POPS WITH A CHANCE OF THUNDER LATE.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
FORECAST POPS HIGH FOR SATURDAY AS FRONT MOVES BACK NORTH AS A
WARM FRONT. THE PROBLEM IS PLENTY OF HIGH PRESSURE ESPECIALLY FROM
THE NAM. WITH THAT IN MIND WILL JUST KEEP IT CHANCE POPS AT THIS
TIME. ANOTHER COLD FRONT MOVES THROUGH SUNDAY AND SUNDAY NIGHT.
THIS FRONT WILL HAVE TO BE MONITORED FOR THE SEVERE THREAT.
GUIDANCE TEMPERATURES FOR SATURDAY SEEM TOO COOL BASED ON THE
WARM FRONT MOVING THROUGH.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
THE COLD FRONT WILL BE JUST ABOUT SOUTH OF THE FORECAST AREA
MONDAY MORNING...A THREAT MAY LINGER IN THE AM IN THE SOUTHERN PORTION
OF THE FORECAST. OF COURSE TIMING IS AN ISSUE.

THE MODELS GFS/DIGEX BRING A COLD FRONT THROUGH ON FRIDAY...WHILE
THE ECMWF BRINGS THE FRONT THROUGH THURSDAY. NONE THE LESS A
THREAT OF PRECIPITATION IS IN THE FORECAST THROUGH THE PERIOD. THE
BEST CHANCE WILL BE THURSDAY AND FRIDAY WITH THE TIMING OF THE
FRONT IN QUESTION. OTHER DAYS THE AIRMASS IS JUST UNSTABLE SO IT
IS MORE DAYTIME HEATING.

GUIDANCE TEMPERATURES ARE GOOD. FRIDAY IS TOUGH WITH THE TIMING OF
THE FRONT IN QUESTION.

&&
