AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
315 AM CDT SUN AUG 27 2000

SHORT RANGE MODELS STILL NOT QUITE ALL IN SYNC WITH NCEP LEANING
WITH CANADIAN AND NGM MODELS. THESE MODELS BEST CAPTURE DECENT SHORT
WAVE OVER CO AND KEEPS IT MORE INTACT AS IT RIDES E TOWARD IL MON
OVER THE TOP OF A STRONG UPPER LEVEL RIDGE OVER THE CENTRAL/SOUTHERN
PLAINS. FORECAST CHALLENGE WILL BE WHETHER THIS FEATURE WILL PRODUCE
CONVECTION MON.

SURFACE ANALYSIS AT 07Z HAS COLD FRONT EXTENDING FROM CENTRAL KS/MO
AND SW IL...S OF KSTL/KEVV...THEN ACROSS SE INDIANA AND TO A LOW
OVER THE SW TIP OF ONTARIO. 1019 HIGH PRESUSURE NEAR JAMES BAY AND
RIDGING SW INTO LAKES SUPERIOR HELPING TO SUPPRESS FRONT A BIT
FURTHER SSW TODAY AND DEVELOP MOSTLY SUNNY SKIES N OF I-70 AND
PARTLY SUNNY S THIS AFTERNOON PER ETA/NGM CURULLES. WILL MENTION
AREAS OF FOG INTO MID MORNING AS POCKETS OF DENSE FOG ANTICIPATED
BEFORE DAYBREAK. ISOLATED CONVECTION STILL S OF I-70...AND WILL NEED
TO MENTION ISOLATED CONVECTION 6 SOUTHERN COUTIES TODAY...ESPECIALLY
EARLY THIS MORNING AND AGAIN WITH DAYTIME HEATING THIS AFTN WHERE
AIR MASS TO BE MORE HUMID AND UNSTABLE...CLOSER TO FRONT IN SW IL.
ENE FLOW FAIRLY LIGHT TODAY SO STILL RATHER HUMID WITH DEWPOINTS IN
THE MIDDLE 60S TO LOWER 70S.

FRONT TO MAKE SLOW LIFT BACK NE TOWARD W/SW IL FROM MO TONIGHT/MON
AS SE FLOW DEVELOPS WITH HIGH PRESSURE MOVING SE ACROSS QUEBEC. SOME
INCREASING WAA/ISENTROPIC LIFT TO WARRENT PROB30/40 MON. COULD BE AS
SOON AS LATE TONIGHT FROM SPI-HUF SW...BUT WILL LEAVE IT DRY TONIGHT
FOR NOW AS CURRENT FORECAST REFLECTS. IN ADDITION...CO SHORT WAVE TO
MOVE E AND COULD ENHANCE SCT CONVECTION. ETA KEEPS IT DRY NEXT 48
HRS WHILE AVN/NGM AND HPC HAVE MAINLY LIGHT QPF MON WITH HEAVIER QPF
OF QUARTER TO A HALF INCH SW OF CWA WHERE ATMOSPHERE MORE UNSTABLE.
STRONG SHORT WAVE RACING E FROM THE NORTHERN ROCKIES ACROSS THE
NORTHERN PLAINS AND INTO MN/WI BY MON NIGHT TO STAY N OF CENTRAL IL.

LIKE MILDER FWC/MAV SUN/MON AS H85 TEMPS WARM WITH 18-22C AND EVEN
1-2C WARMER DURING MIDWEEK WHEN HIGHS REACH NEAR 90 WITH LOWS OF 70.

AGREE WITH CURRENT EXTENDED FORECAST. STRONG UPPER LEVEL RIDGE
ACTUALLY BUILDS N ACROSS MO TUE WHILE STRONG CANADIAN SHORT WAVES
FLATTEN TOP OF RIDGE OVER NORTHERN TIER OF THE U.S. WHERE FAST W-E
ZONAL FLOW SETS UP. STILL THINK STRONG RIDGE THAT GETS CLOSER TO IL
WILL KEEP CENTRAL IL DRY WITH GOOD CAP IN PLACE. EXPECT ABOVE NORMAL
TEMPS/HUMIDITY DURING MID WEEK WHILE CONVECTION AFFECTS NORTHERN
PLAINS AND GREAT LAKES.
