AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
257 PM CDT SUN JUN 22 2008

.DISCUSSION...
ISSUED 257 PM CDT SUN JUN 22 2008

GFS/NAM-WRF LOOK PRETTY SIMILAR THROUGH 84HRS IN THE UPPER LEVEL
AND SURFACE PATTERNS. WITH THE MAIN CONCERNS BEING CHANCES OF PCPN
TONIGHT AND THEN TIMING OF RETURN OF PCPN BY TUESDAY/TUE NIGHT...A
BLEND OF THE MODELS...EVEN UKMET/GEM AND NEW 12Z ECMWF SEEMS IN
ORDER. SURPRISINGLY ALL THESE MODELS LOOK SIMILAR FOR TUE INTO
WED.

IN THE EXTENDED...WILL MAINTAIN CONTINUITY FROM PREVIOUS FORECAST
AS ALL MODELS CONTINUE TO SHOW FAST QUASI-ZONAL PATTERN FOR DAYS
4-7. MAIN CONCERNS DURING THIS PERIOD CONTINUE TO BE CHCS OF PCPN
AND WHEN THERE WILL BE ANY BREAKS IN THE PCPN.

SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT

SCATTERED CONVECTION HAS FINALLY BROKEN OUT OVER THE EASTERN PARTS
OF THE CWA THIS AFTERNOON. 18Z SOUNDING SHOWED HIGH CAPE AND STEEP
LAPSE RATES. HOWEVER...LACK OF SFC DEWPOINTS MAY BE REASON WHY
STORMS ARE NOT THAT STRONG. BEST AXIS OF INSTABILITY ACTUALLY IS
SOUTH OF WHERE THE CONVECTION IS GOING...SO NOT CONFIDENT THAT WE
WILL SEE ANY SVR WEATHER NOW THIS EVENING. HOWEVER...WILL STILL
CARRY SCT STORMS IN THE EAST AND SOUTHEAST TONIGHT TIL 06Z.
ANOTHER TROUGH WAS ROTATING DOWN FROM WI AND WILL MOVE INTO IL
THIS EVENING...PLUS THERE IS A NICE CU FIELD EVIDENT ON SATELLITE
LOOPS. THEREFORE WILL KEEP A SLIGHT CHC OF SHOWERS AND
THUNDERSTORMS IN THE REMAINDER OF THE ARE TONIGHT AS WELL.

THEN COOL CANADIAN HI PRSS WILL BUILD IN BEHIND THIS LAST TROUGH
LATE TONIGHT AND INTO TOMORROW. THIS WILL BEING DRY WEATHER FOR
THE BEGINNING OF THE WORK WEEK. THE DRY WEATHER WILL NOT LAST LONG
AS THE HIGH WILL QUICKLY PUSH EAST OF THE AREA TUESDAY AND BRING
THE RETURN OF SOUTHERLY WINDS WITH INCREASING WAA AND MOISTURE
ADVECTION BY MIDDLE OF THE WEEK.

A WEAK WARM FRONT COMBINED WITH A WEAK SHORT WAVE IN THE FAST
QUASI-ZONAL FLOW WITH BRING CHC OF PCPN BACK TO THE WESTERN AREAS
BY TUESDAY. THIS IS ACTUALLY SOONER THAN FIRST THOUGHT. THIS
SOUTHERLY SURFACE FLOW WILL CONTINUE INTO WED WITH CHCS OF PCPN TUE
NIGHT THROUGH WED NIGHT ACROSS THE WHOLE CWA. HAVE INCREASED POPS
TO LITTLE BIT HIGHER CHC AS MODELS INDICATE A NICE WARM FRONT WILL
LIFT THROUGH THE AREA TUE NIGHT INTO WED. THE WARM FRONT SHOULD
THEN BE NORTH OF THE CWA WED NIGHT BUT IL WILL THEN BE A
WARM...HUMID AND UNSTABLE AIRMASS FOR WED NIGHT. THIS COULD BE ONE
OF THE DRY PERIODS WE SEE...BUT FOR NOW WILL KEEP A 30 POP IN THE
AREA UNTIL BETTER TIMING CAN BE DETERMINED.

COOL CANADIAN HI PRSS WILL BRING COOLER AIR INTO THE REGION.
BELIEVE TEMPS WILL BE BELOW NORMAL FOR JUNE AS 850 TEMPS WILL DROP
TO AROUND +12C. GUIDANCE ALSO SUGGEST COOLER TEMPS AS WELL. SO WILL
HAVE BELOW NORMAL TEMPS FOR MON...SLIGHTLY WARMER FOR TUE...THEN
MUCH WARMER AS WARM FRONT MOVES THROUGH THE AREA.

LONG TERM...THURSDAY THROUGH SUNDAY

FAST ZONAL TYPE FLOW WILL REMAIN OVER THE REGION THE REST OF THE
WEEK AND INTO THE WEEKEND. THIS FAR OUT HARD TO PINPOINT ANY SHORT
WAVE SO BELIEVE CURRENT FCST OF CHC THUNDERSTORMS THROUGH MOST OF
THE PERIOD IS STILL WARRANTED. EXTENDED MODELS DO SHOW A BETTER
DEFINED FRONT THAT IS FCST TO MOVE THROUGH THE AREA SAT/SAT NIGHT.
THEREFORE WILL ADD A BREAK IN THE PCPN FOR SUNDAY.
OTHERWISE...CHANCE OF THUNDERSTORMS WILL BE THE RULE FOR THURSDAY
THROUGH SAT NIGHT.

AREA WILL SEE CONTINUED SOUTHERLY SFC FLOW THROUGH THE PERIOD. SO
TEMPS WILL REMAIN WARM AND LIKELY BE ABOVE NORMAL DURING THE DAY.
MEX GUIDANCE SHOWS THIS WELL AS WELL SO DID NOT STRAY TO FAR FROM
GUIDANCE.

.AVIATION...
ISSUED 1221 PM CDT SUN JUN 22 2008

SHORTWAVE RIDGING NOW MOVING INTO ILLINOIS AND SHOULD...IN
COMBINATION WITH SURFACE DRY AIR ADVECTION...SHOULD INHIBIT
DEVELOPMENT UNTIL LATE AFTERNOON. STILL QUITE A BIT OF UNCERTAINTY
AS TO THE EXPECTED COVERAGE AND WILL ALTER THE TERMINAL FORECASTS
FROM TEMPO TO VCTS. SERIES OF WEAK SURFACE BOUNDARIES CONTINUE TO
ROTATE AROUND GREAT LAKES MID-LEVEL LOW AND ARE CAUSING MINOR WIND
SHIFTS AT INTERVALS. HOWEVER AS ATMOSPHERE DECOUPLES THIS
EVENING...WINDS SHOULD STABILIZE AND DECREASE.
