.DISCUSSION...

THE TROUGH OVER MINNESOTA AND THE EASTERN DAKOTAS IS FORECAST TO
MOVE SOUTHEAST TO NORTHWEST ILLINOIS BY 06 UTC MONDAY. THERE IS A
300 MB JET STREAK FROM ALBERTA TO NEBRASKA AT 00 UTC. BY 08 UTC THE
PROFILER NETWORK SHOWS THE JET STREAK INTO IOWA WITH A 50 KNOT WIND.
THE SOUNDING AT MINNEAPOLIS SHOWS THE BACKING WIND AND A 3 DEGREES
C/KM LAPSE RATE BETWEEN 850 AND 700 MB. THERE IS SOME INSTABILITY
AND SHEAR TO SUPPORT THE GROWTH OF THIS TROUGH AT ITS CURRENT
WAVELENGTH. THE GFS AND NAM MODELS SHOW THE TROUGH GROWING AS IT
MOVES EAST. WITH THE APPROACHING TROUGH AND THE HIGHER DEWPOINTS IN
THE WESTERN HALF OF THE OUR FORECAST AREA...WE WILL RAISE THE POPS
FOR THIS AFTERNOON AND TONIGHT FOR THUNDERSTORMS. THE DRY AIR IS
OVER THE CHICAGO AREA AND NORTHWEST INDIANA. SURFACE DEWPOINT
ANALYSIS SHOWS LOWER DEWPOINTS OVER COOK COUNTY WITH AN SOUTHEAST
LOW LEVEL WIND UP TO AROUND 916 MB. THIS IS SEEN ON THE ACARS
SOUNDING AT 737 UTC AT ORD. WE WILL HAVE LOWER POPS IN NORTHEAST
ILLINOIS AND NORTHWEST INDIANA.

THE WAVE WILL BE OVER NORTHERN ILLINOIS THROUGH WEDNESDAY. THERE
WILL BE SEVERAL 500 MB VORTICITY MAXIMUM ROTATING THROUGH THE WAVE
OVER NORTHERN ILLINOIS. WE WILL KEEP A CHANCE OF RAIN MONDAY AND

TUESSDY NIGHT. WE LOWERED THE TEMPERATURE FORECAST THROUGH THE EARLY
