AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
251 PM CDT MON JUN 26 2006

.DISCUSSION...

MAIN FORECAST ISSUE REMAINS NEAR DAILY SMALL CHANCES FOR SHOWERS
AND THUNDERSTORMS THROUGH MUCH OF THE WEEK.

SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON OVER THE
EASTERN HALF OF ILLINOIS IN RESPONSE TO AN UPPER-LEVEL LOW
DROPPING SOUTHWARD THROUGH IOWA AND NORTHWEST ILLINOIS. THIS LOW
IS EXPECTED TO CONTINUE DROPPING SOUTHWARD TONIGHT...FILLING AS IT
DOES SO. THE COLD POOL OF AIR IN ASSOCIATION WITH THE LOW PAIRED
WITH AMPLE SURFACE-BASED INSTABILITY WILL KEEP THE CHANCE OF
SHOWERS AND THUNDERSTORMS ALIVE THIS EVENING. WITH THE LOSS OF
DIURNAL HEATING...THE STORMS SHOULD BECOME MORE SPORADIC AS THE
NIGHT PROGRESSES...BUT WE STILL CANNOT RULE OUT AN ISOLATED STORM
OR TWO.

THE PATTERN WITH AN UPPER-LEVEL TROUGH OVER THE EASTERN UNITED
STATES IS FORECAST TO PERSIST THROUGH MID TO LATE WEEK. WAVES OF
ENERGY DROPPING SOUTH INTO THE BASE OF THIS TROUGH WILL KEEP A
DAILY CHANCE OF SHOWERS AND THUNDERSTORMS IN THE FORECAST. TIMING
AND LOCATION OF THE BEST CHANCES WILL BE TRICKY AS THE MODELS HAVE
A TOUGH TIME RESOLVING THE INDIVIDUAL PERTURBATIONS FARTHER OUT
WITH TIME. HOWEVER...THE BEST CHANCES SHOULD EXIST OVER OUR NORTHERN
AND EASTERN COUNTIES IN CLOSER PROXIMITY TO THE UPPER-LEVEL TROUGH.
IN ADDITION...MORE COVERAGE SHOULD OCCUR DURING THE AFTERNOON AND
EVENING HOURS COINCIDENT WITH PEAK DAYTIME HEATING.

A LESS AMPLIFIED PATTERN IS EXPECTED TO DEVELOP BY THE END OF THE
WORK WEEK. THE LATEST OPERATIONAL GFS RUNS HAVE COME ON BOARD
WITH SHIFTING THE TROUGH AXIS EAST OF THE FORECAST AREA BY FRIDAY.
THIS IS SIMILAR TO THE DGEX...BUT STILL NOT AS PROGRESSIVE AS THE
ECMWF AND TO A LESSER EXTEND THE CANADIAN GLOBAL.

WHILE CONFIDENCE REGARDING THE OVERALL PATTERN EVOLUTION HAS
IMPROVED...TIMING OF INDIVIDUAL PRECIPITATION CHANCES IS STILL AN
EXERCISE IN FRUSTRATION. FOR COLLABORATION AND CONTINUITY SAKE...WE
WILL MAINTAIN SMALL CHANCES WEDNESDAY NIGHT AND THURSDAY. AVAILABLE
MODEL GUIDANCE SUGGESTS A DRIER PERIOD FROM THURSDAY NIGHT THROUGH
FRIDAY NIGHT...SO WE MAINTAINED DRY CONDITIONS THURSDAY NIGHT...
AND DROPPED POPS FROM THE FRIDAY AND FRIDAY NIGHT PERIODS.

OVER THE WEEKEND...BOTH THE GFS AND DGEX INDICATE THE APPROACH OF
MORE NORTHERN STREAM ENERGY WHICH MAY HELP TO PUSH A SURFACE
FRONTAL BOUNDARY TOWARD OR INTO THE REGION. AS A RESULT...WE WILL
ADD A 20 POP FROM SATURDAY THROUGH MONDAY.

TEMPERATURES THROUGH THE PERIOD WILL MODERATE FROM BELOW NORMAL
OVER THE NEXT FEW DAYS TO SLIGHTLY ABOVE SEASONAL NORMS BY NEXT
WEEKEND. THIS IS ALREADY REFLECTED IN THE GOING FORECAST...WHICH
COMPARES FAVORABLY WITH RECENT MOS GUIDANCE.
