IN THE UPPER LVLS, A STOUT REGION OF HIGH PRESSURE WILL BE
POSITIONED OVER THE FOUR CORNERS REGION OF THE CONUS AND
NORTHWESTERLY TO NORTHERLY FLOW WILL BE PRESENT OVER THE STATE OF
ARKANSAS. INTO THE WORKWEEK, THE CENTER OF THE UPPER LVL HIGH
PRESSURE BECOME ELONGATED AND FIXATES OVER THE NORTHERN PLAINS
REGION OF THE CONUS. AN UPPER LVL LOW PRESSURE CENTER WILL ACTUALLY
RETROGRADE BACK WESTWARD DURING THE MIDDLE PORTION OF THE WORKWEEK
INFLUENCED BY THE UPPER LVL HIGH PLANTED ACROSS THE NORTHERN PLAINS
INTO THE MID-WEST REGION OF THE CONUS. INTO THE LATER PORTION OF THE
WORKWEEK, AN UPPER LVL HIGH PRESSURE CENTER BEGINS TO DEVELOP OVER
SOUTHERN PLAINS REGION OF THE CONUS.
AT THE SFC, A STATIONARY BOUNDARY ACROSS SOUTHERN MISSOURI WILL
BEGIN TO PUSH SOUTHWARD SLOWLY AS A COLD FRONT DURING THE
AFTERNOON/EVENING TIMEFRAME ON SATURDAY. IT IS THE PARAMETER SPACE
ALONG AND AHEAD OF THIS FEATURE ACROSS NORTHERN AND CENTRAL ARKANSAS
WHICH WILL SET THE TABLE FOR THE POTENTIAL OF SEVERE WEATHER. LATEST
CAMS PORTRAY A PARAMETER SPACE WITH MODERATE INSTABILITY AND NEAR-
ZERO SHEAR; ADDITIONALLY, 0-3 KM LAPSE RATES ABOVE 9 C/KM AND DCAPE
VALUES IN THE RANGE OF 1,000 J/KG TO 1,300 J/KG WILL PRESENT AN
ENVIRONMENT SUGGESTIVE OF DAMAGING WIND GUSTS ASSOCIATED WITH
THUNDERSTORM DEVELOPMENT. A FEW INSTANCES OF SEVERE HAIL WILL BE
POSSIBLE AND CAMS HAVE LENGTHENED THE DURATION OF THIS EVENT (IN
TANDEM WITH HIGH PW VALUES OF 1.7-2.0 INCHES) WHICH MAY LEAD TO
MULTIPLE ROUNDS OF RAIN AND STORMS TRAINING OVER THE SAME LOCATIONS
WHICH WOULD PRESENT A THREAT FOR FLASH FLOODING.
INTO SUNDAY AFTERNOON, THE COLD FRONT WILL PUSH INTO SOUTHERN
ARKANSAS AND BE MAKING A RUN TOWARD THE ARKANSAS/LOUISIANA
BORDER. LATEST CAMS SHOW ADDITIONAL DEVELOPMENT ACROSS THE
SOUTHERN PORTION OF THE STATE, BUT THIS PARAMETER SPACE WILL NOT
BE AS PRIMED FOR SEVERE WEATHER AS THE ACTIVITY FROM SATURDAY
(TODAY). HOWEVER, DAMAGING WIND GUSTS WILL BE A PRIMARY CONCERN IN
STORMS THAT DO BECOME SEVERE.
THE COLD FRONT WILL STALL SOUTH OF ARKANSAS AS A STATIONARY FRONT BY
EARLY INTO THE WORKWEEK AND REMAIN THROUGH THE MID-WORKWEEK AND
KEEP POP CHANCES DECENT ACROSS THE STATE FOR ISOLATED RAIN AND
STORMS; HOWEVER, WIDESPREAD ACTIVITY IS NOT ANTICIPATED AND POP
CHANCES WILL DIMINISH LATER INTO THE WEEK AS THE STATIONARY
BOUNDARY MOVES AWAY FROM THE STATE AND A SURFACE HIGH PRESSURE
CENTER MOVES INTO THE REGION.
