CURRENT PLACEMENT OF RAINFALL. GOOD ISENTROPIC LIFT CONTINUES OVER
THE AREA WHICH IS HELPING IN COVERAGE OF RAINFALL. CLOUD COVER AND

RAINFALL AND HAVE HIGHER TEMPS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY MORNING/...
SURFACE LOW WILL CONTINUE TO TRACK TO THE NORTHEAST DURING THE
OVERNIGHT HOURS AND WILL BE LOCATED OVER NORTHERN OHIO BY 12Z. AS
SURFACE LOW MOVES TO THE NORTHEAST THE GREATEST CHANCE OF
PRECIPITATION WILL AS WELL. NAM IS SLIGHTLY FASTER IN MOVING AREA
OF PRECIP OUT OF AREA THAN GFS WHICH IS THE OPPOSITE OF YESTERDAY.
WENT WITH A BLEND BETWEEN THE TWO SINCE BOTH ARE DOING RATHER WELL
IN CURRENT PLACEMENT OF LOW. GREATEST ISENTROPIC LIFT CUTS OFF BY
06Z AND THEREFORE HAVE CUT POPS DOWN AFTER THAT TIME FRAME. A LULL
IN THE PRECIPITATION WILL OCCUR ACROSS WESTERN PORTIONS OF THE
REGION THURSDAY MORNING. BY THURSDAY AFTERNOON UPPER TROUGH PIVOTS

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
SURFACE HIGH WILL BRIEFLY BUILD INTO THE OHIO VALLEY FROM THE
SOUTHWEST ON FRIDAY. SOUTHERLY FLOW OVERNIGHT WILL BE FOUND AHEAD OF
THE NEXT COLD FRONT THAT WILL MOVE SOUTHEAST ON SATURDAY. SHOWERS
ARE EXPECTED WITH THIS FROPA...AND SOME ISOLATED THUNDER WILL ALSO
BE A POSSIBILITY. ANY LINGERING RAIN SHOULD EXIT TO THE SOUTHEAST ON
SATURDAY EVENING AS THIS IS A NICELY PROGRESSIVE SYSTEM.
TEMPERATURES WILL BE BELOW NORMAL THROUGH MUCH OF THE EXTENDED
FORECAST PERIOD DUE TO THE AIRMASS BEHIND SATURDAYS FRONT.

SOME COLD POOL SHOWERS THAT ARE DIURNALLY INDUCED WILL BE POSSIBLE
ON SUNDAY AND MONDAY...ESPECIALLY WITH THE COLDEST AIR FOUND SUNDAY
AFTERNOON WITH H8 TEMPS AROUND +12. GUIDANCE BEYOND DAY 5 AND 6 IS
SHOWING A GOOD SHOT OF PRECIPITATION AHEAD OF THE NEXT STRONG COLD
FRONT AND SURFACE LOW. THIS APPEARS OVERDONE UNTIL THE LOW AND
SURFACE FRONT HAVE A MUCH CLOSER PROXIMITY...ON WEDNESDAY. WILL HAVE
A CHANCE FOR SHOWERS IN THE WARM SECTOR TUESDAY JUST BECAUSE OF THE
STRONG SOUTHERLY FLOW PUMPING IN SIGNIFICANT MOISTURE.

COVER AND COLD POOL THINKING...MORE TOWARDS THE GFS TEMPERATURES.

&&

BEEN AFFECTING THE REGION FOR MOST OF THE DAY AND WILL LIKELY
