PERSISTENT RIDGE PATTERN CENTERED OVER THE REGION WILL REMAIN
IN PLACE THIS WEEK FOSTERING A HOT AND HUMID AIRMASS WITH DAILY
HIGHS WELL INTO THE 90S AND HEAT INDICES BETWEEN 105-112
DEGREES. HEAT HEADLINES REMAIN IN EFFECT FOR THE ENTIRE REGION
WITH A EXTREME HEAT WARNING COVERING ALL OF SOUTHEAST MISSOURI,
PORTIONS OF WESTERN KENTUCKY AND SOUTHERN ILLINOIS, WITH HEAT
ADVISORIES ELSEWHERE. THESE HEADLINES WILL REMAIN IN PLACE
THROUGH THURSDAY. UPPER RIDGING TODAY WILL LIKELY KEEP A GOOD
PORTION OF THE REGION RAIN FREE. HOWEVER, LATEST ANALYSIS AND
MODEL GUIDANCE SHOWS SLIGHTLY ELEVATED MOISTURE CONVERGENCE
ACROSS SOUTHEAST MISSOURI SOUTHERN ILLINOIS, AND WESTERN
KENTUCKY TIED TO A BOUNDARY TO SUPPORT ISOLATED TO WIDELY
SCATTERED CONVECTION ACROSS THESE AREAS FROM NOW THROUGH EARLY
EVENING.
RIDGING ALOFT EXPANDS FURTHER MID TO LATE WEEK SUPPRESSING
CONVECTIVE COVERAGE, AND LEADING TO TEMPERATURES IN THE MID TO
UPPER 90S. MAX HEAT INDEX VALUES WEDNESDAY AND THURSDAY WILL TOP
OUT IN THE 105 TO 112 DEGREE RANGE. RIDGING BREAKS DOWN THIS
WEEKEND WHICH WILL LIKELY SUPPORT AT LEAST A SLIGHT INCREASE IN
COVERAGE OF SHOWERS AND STORMS. ADDITIONALLY, TEMPERATURES WILL
LIKELY COOL OFF BY A COUPLE OF DEGREES. STILL, HEAT INDICES ARE
EXPECTED TO TOP OUT IN THE 105-110 RANGE, SO LIMITED RELIEF IN
TERMS OF THE HOT AND HUMID AIRMASS. DEEP LAYER RIDGING BUILDS
ACROSS THE PLAINS AGAIN NEXT WEEK. THIS BRINGS A RETURN OF
HIGHS IN THE MID TO UPPER 90S AND MOSTLY DRY CONDITIONS.
