DISCUSSION
ISSUED AT 300 PM CDT WED JUL 8 2026
THIS AFTERNOON THROUGH TONIGHT: AS WAS THE CASE YESTERDAY, WE'RE
SEEING MOST OF THE DEEP CONVECTION FOCUSED OUTSIDE OF OUR FORECAST
AREA THIS AFTERNOON. A FEW STORMS COULD MANAGE TO MOVE IN OR
DEVELOP OVER THE AREA AS WE GO THROUGH THE EVENING, BUT COVERAGE
SHOULD STAY FAIRLY SPARSE BY JULY STANDARDS.
THURSDAY INTO THE WEEKEND: RAIN CHANCES WILL DIMINISH FOR THU-
FRI AND REMAIN RELATIVELY LOW FOR THIS TIME OF THE YEAR AS THE
SUBTROPICAL RIDGE REBUILDS OVER THE FORECAST AREA. ACCOMPANYING
THE BUILDING RIDGE WILL BE AN INCREASING HEAT DANGER RISK WITH
H850 TEMPS APPROACH 21 DEG C AND LOW LEVEL FLOW DEVELOPING A MORE
WESTERLY COMPONENT. WE WILL CONTINUE TO MESSAGE THIS THREAT WITH
A HEAT DANGER GRAPHIC AND COORDINATE WITH NEIGHBORING FORECAST
AREAS CONCERNING ANY HEAT ADVISORY ISSUANCES THAT MAY BECOME
NECESSARY.
EARLY TO MID NEXT WEEK: GLOBAL MODELS HAVE A HAD A STRONG SIGNAL
FOR A SHORTWAVE TROUGH ROTATING AROUND THE RIDGE AND SENDING A
BOUNDARY TOWARD OUR AREA IN THE MON-TUE TIME FRAME, AND THIS COULD
SUPPORT A SIGNIFICANT ROUND OR TWO OF CONVECTIVE RAINFALL. ALONG
WITH THIS, THE HEAT WILL DIMINISH TO BELOW DANGEROUS LEVELS. FOR
NEXT WEDNESDAY, A TYPICAL MID SUMMER REGIME WITH CONVECTIVE
RAINFALL FOCUSED MAINLY OVER SOUTHERN PORTIONS OF THE AREA SHOULD
EXIST. /EC/
