159 PM CDT UPDATE:
THE PRESENCE OF CONVECTION AND CONVECTIVE DEBRIS CLOUDS OVER
CENTRAL ILLINOIS CONTINUES TO COMPLICATE THE FORECAST EVOLUTION
THIS AFTERNOON INTO THIS EVENING. THE EFFECTIVE WARM FRONT
CURRENTLY EXTENDS FROM JUST SOUTH OF THE QUAD CITIES, THEN JOGS
SOUTHEAST TO SOUTH OF PEORIA BEFORE TURNING EAST ACROSS MCLEAN
COUNTY TOWARD RANTOUL. THE ONGOING CONVECTION HAS MADE THIS
BOUNDARY A BIT DIFFUSE ACROSS CENTRAL ILLINOIS, BUT A DECENT
AMOUNT OF CLEARING OVER NORTHERN MISSOURI INTO SOUTHERN IA AND
NORTHWEST ILLINOIS IS ALLOWING FOR A QUICK NORTHWARD PUSH WITH THE
WARM FRONT. ABUNDANT HEATING IS NOT NEEDED TO DESTABILIZE THE
ENVIRONMENT TODAY, AND EVEN WHERE THICK CIRRUS IS PRESENT IN THE
COOL SIDE OF THE WARM FRONT, TEMPS ARE RISING 5F+ IN JUST ONE
HOUR.

IN THE WARM SECTOR OVER NORTHERN MISSOURI, CONVECTION HAS INITIATED
ALONG THE COLD FRONT AND IS ENTERING AN AREA OF INCREASED MLCAPE
NEAR 1000 J/KG AND EFFECTIVE SRH VALUES OF 200-400 M2/S2. RECENTLY
ISSUED SPC MCD 0251 OUTLINES THE INITIAL EXPECTED EVOLUTION IN IA/MO
QUITE WELL. THERE ARE CONTINUED EXPECTATIONS THAT SIMILAR PARAMETERS
WILL EXPAND EASTWARD WITH WITH COLD FRONT AND IN THE VICINITY OF THE
TRIPLE POINT AS SOME SURFACE HEATING OCCURS EVEN AMIDST MID/UPPER
CLOUD COVER.

OVERALL STORM EVOLUTION AND TIMING HAS NOT CHANGED SIGNIFICANTLY,
WITH THE GREAT TORNADO (POSSIBLY SIGNIFICANT) RISK FOCUSED ACROSS
THE WEST CENTRAL AND SOUTHWEST CWA. HOWEVER, A NARROW WINDOW OF
INCREASED TORNADO RISK IS STILL EXPECTED ACROSS THE REMAINDER OF THE
CWA GENERALLY SOUTH OF I-88 AS A LOCALIZED NORTHWARD SURFACE IN THE
WARM FRONT REMAINS POSSIBLE AHEAD OF THE TRIPLE POINT.
