DISCUSSION
ISSUED AT 250 AM CDT FRI JUL 31 2026
FRIDAY/FRIDAY NIGHT (TODAY/TONIGHT):
A HEAT ADVISORY WILL BE IN PLACE TODAY ACROSS MOST OF CENTRAL AND
SOUTHERN ARKANSAS AS A WARM FRONT IS PROGGED TO TRACK NORTHEASTWARD
ACROSS THE STATE. THE BOUNDARY WILL LEAD TO A SLIGHT UPTICK OF AIR
TEMPERATURE, DEWPOINT TEMPERATURES, AND THE APPROACHING COLD FRONT
WILL LEAD TO A POSSIBILITY OF COMPRESSIONAL HEATING WHICH WILL
ELEVATE HEAT INDEX VALUES AND HEAT RISK ACROSS THE STATE. A
POTENTIAL UPGRADE OF HEAT PRODUCTS TO AN EXTREME HEAT WARNING WAS
CONTEMPLATED FOR THE CWA, BUT DECIDED TO REMAIN CONSERVATIVE WITH A
HEAT ADVISORY GIVEN THE TREND OF RAIN COOLED AIR MOVING INTO THE CWA
VIA NORTHWESTERN AND NORTHERN ARKANSAS AS OF 2 AM CDT IN ADDITION TO
INCREASING CLOUD COVER FORECASTED OVERALL THROUGHOUT THE DAY.
BEGINNING THIS AFTERNOON, FROM WEST TO EAST ACROSS THE NORTHERN AND
CENTRAL PORTIONS OF THE STATE, A PARAMETER SPACE WILL BECOME
CONDUCIVE FOR A FIRST ROUND OF CONVECTION AHEAD OF THE APPROACHING
COLD FRONT TO DEVELOP. A REGION OF MODERATE INSTABILITY COUPLED WITH
DEEP-LAYER SHEAR IS PROGGED TO BE IN PLACE ACROSS MUCH OF NORTHERN
AND CENTRAL ARKANSAS. ANALYSIS OF BOTH THE 00Z AND 06Z SUITES OF
GUIDANCE DEPICTS MLCAPE BETWEEN 1,000 J/KG AND 2,000 J/KG PRESENT
WITHIN THE TIMESCALE AND OVERALL DEEP LAYER SHEAR WHICH WILL BE
PRESENT ACROSS THIS REGION OF INSTABILITY AS WELL. SIMPLY PUT, BOTH
MODERATE INSTABILITY AND ADEQUATE SHEAR FOR THE DEVELOPMENT OF A
SUPERCELL OR TWO WILL BE POSSIBLE. STORM MODE CONFIDENCE DOES REMAIN
LOW FOR THE FIRST ROUND OF ACTIVITY WHICH IS EXPECTED TO DEVELOP.
INTO THIS EARLY EVENING AND CONTINUING INTO THE LATE EVENING HOURS,
AS THE COLD FRONT SWEEPS ACROSS THE STATE. ANALYSIS OF LATEST
GUIDANCE CONTINUES TO TREND TOWARDS MODERATE INSTABILITY AND
ADEQUATE SHEAR AVAILABLE ACROSS NORTHERN AND CENTRAL ARKANSAS. THE
LATEST CAMS INDICATE THAT THE STORM MODE ALONG THE COLD FRONT WILL
BE MULTICELLULAR AND QUICKLY BECOMING LINEAR.
EXPECT THE MAIN HAZARD OF ANY STORMS THAT DO MANAGE TO BECOME SEVERE
THIS AFTERNOON INTO THIS EVENING TO BE DAMAGING WIND GUSTS, BUT
ACROSS FAR NORTH-CENTRAL ARKANSAS AND FAR NORTHEASTERN ARKANSAS A
VERY LOW, BUT PRESENT TORNADO POTENTIAL WILL BE PRESENT. IT WILL BE
A MUST TO PAY ATTENTION THROUGHOUT THE DAY TO BOTH ROUNDS OF STORMS
EXPECTED TO DEVELOP AHEAD AND ALONG THE BOUNDARY THROUGHOUT THE DAY.
SATURDAY/SUNDAY/MONDAY:
A COOLER AND DRIER AIRMASS IS PROGGED TO OCCUPY THE STATE BEHIND THE
COLD FRONT WHICH IS FORECAST TO MOVE ACROSS THE STATE ON FRIDAY. AT
THE SFC, HIGH PRESSURE MOVES INTO THE REGION AND OVERALL
TEMPERATURES NEAR TO BELOW NORMAL WILL BE OBSERVED OVER THIS THREE-
DAY STRETCH. THE COLD FRONT IS EXPECTED TO COMPLETELY CLEAR
ARKANSAS, BUT BECOME A STATIONARY FRONT WITHIN THE MID-SOUTH REGION
OF THE CONUS WHICH WILL KEEP LIMITED OPPORTUNITIES FOR POPS IN PLAY
ACROSS EASTERN ARKANSAS GIVEN THE CLOSE PROXIMITY OF THE BOUNDARY TO
THE EASTERN TIER OF THE STATE.
TUESDAY/WEDNESDAY/THURSDAY:
AN ELONGATED UPPER LVL RIDGE BEGINS TO STRENGTHEN OVER THE ENTIRE
SOUTHERN TIER OF THE CONUS EXTENDING FROM OVER THE SOUTHWESTERN
REGION OF THE CONUS TO OVER THE MID-SOUTH REGION OF THE CONUS. AT
THE SFC, HIGH PRESSURE MOVES INTO THE REGION. CONSEQUENTLY,
TEMPERATURES BEGIN TO INCREASE OVERALL AND A HOT AND DRY PATTERN
WILL ONCE AGAIN TAKE CONTROL OF THE FORECAST. INTO THE MIDDLE OF THE
UPCOMING WEEK, HEAT PRODUCTS WILL ONCE AGAIN LIKELY BE WARRANTED
ACROSS MOST OF THE STATE AND POP CHANCES WILL DIMINISH.
