AN AMPLIFIED UPPER LEVEL PATTERN ACROSS THE CONUS EARLY THIS
MORNING WITH PRONOUNCED DEEP UPPER TROUGH ACROSS THE WESTERN US
EXTENDING FROM THE NORTHERN PLAINS TO THE DESERT SOUTHWEST. UPPER
LEVEL RIDING CONVERSELY REMAINS IN PLACE ACROSS THE EASTERN HALF
OF THE CONUS WITH THE UPPER HIGH CENTERED OVER THE OHIO RIVER
VALLEY REGION.
TEMPERATURES EARLY THIS MORNING RANGE FROM THE UPPER 70S TO LOWER
80S ACROSS MUCH OF ARKANSAS UNDER CLEAR SKIES WITH LIGHT AND
VARIABLE WINDS.
DRY CONDITIONS WHERE NOTED ACROSS THE STATE ON TUESDAY. HI RES
MODEL DATA LATER TODAY SHOWS AN AREA OF ENHANCED LOW LEVEL
MOISTURE ADVECTING INTO PARTS OF FAR SOUTHEAST AND SOUTHERN
ARKANSAS THIS AFTERNOON. THE STORM PREDICTION CENTER HAS PLACED A
MARGINAL RISK FOR STRONG TO SEVERE THUNDERSTORMS THIS AFTERNOON
ACROSS PORTION OF FAR SOUTHEASTERN ARKANSAS. BUFKIT AND DESI
SOUNDINGS OVER SOUTHERN AND FAR SOUTHEAST ARKANSAS SHOW
PRECIPITABLE WATER VALUES AROUND 1.85 INCHES WHICH IS JUST A TAD
BELOW THE 90TH PERCENTILE FOR EARLY JULY. STRONG SURFACE HEATING
THIS AFTERNOON ACROSS THE AFOREMENTIONED AREAS WILL SUPPORT AMPLE
BUOYANCY WITH SURFACE BASED CAPE VALUES IN THE 2500 TO 3000 J/KG
WITH LITTLE TO NO CAP ACROSS THE AREA. THE COVERAGE OF SHOWERS AND
THUNDERSTORMS WILL REMAIN ISOLATED ACROSS THE AREA DUE TO WITH NO
REAL FORCING MECHANISM. BUFKIT AND DESI SOUNDINGS EARLY THIS
MORNING SHOW THE PRESENCES OF MID LEVEL DRY AIR AND STEEP LOW
LEVEL LAPSE RATES WOULD FAVOR AN ISOLATED DAMAGING WIND OR
MICROBURST POTENTIAL WITH THE STRONGEST THUNDERSTORMS.
GUIDANCE SHOWS UPPER LEVEL HIGH PRESSURE CURRENTLY OVER THE
OHIO RIVER VALLEY WILL STAY NEAR STATIONARY TODAY, THEN GRADUALLY
MOVE EAST-NORTHEAST TOWARD THE CAROLINAS AROUND FRIDAY. THE RIDGE
OF HIGH PRESSURE IS EXPECTED TO FLATTING OUT IN RESPONSE TO THE
UPPER TROUGH ACROSS THE WESTERN US EJECTING NORTHEAST INTO THE
NORTHERN AND CENTRAL PLAIN FRIDAY INTO SATURDAY. SHOWER AND
THUNDERSTORM CHANCES WILL BE TIED TO DIURNAL HEATING EACH DAY
THROUGH THE HOLIDAY WEEKEND. AS WE HEAD INTO NEXT WEEK, MODEL
GUIDANCE SHOWS RIDGING REBUILDING OVER PARTS OF THE SOUTHERN
PLAINS WITH TROUGHING MAINLY CONFINED TO THE PACIFIC NORTHWEST
AND NORTHERN AND CENTRAL PLAINS. A SURFACE COLD FRONT WILL DIVE
OUT OF THE NORTHERN PLAINS THIS WEEKEND REACHING AS FAR SOUTH AS
THE OZARK PLATEAU BY EARLY NEXT WEEK. HIGH PRESSURE OVER THE
SOUTHEASTERN US CONTINUE TO PULL DEEP MOISTURE NORTHWARD INTO THE
STATE PROVIDING INCREASING CLOUDINESS AND RAIN AND STORM CHANCES
THAT WILL KEEP TEMPERATURES IN THE LOWER TO MID 90S THROUGH THE
MIDDLE PART OF NEXT WEEK.

(06Z TAFS)
ISSUED AT 1203 AM CDT WED JUL 1 2026
VFR CONDITIONS WILL PREVAIL THROUGH THE ENTIRE FORECAST PERIOD AS
HIGH PRESSURE CONTINUES TO REMAIN IN CONTROL. LIGHT SURFACE
SOUTHEAST TO SOUTHWEST WINDS WILL PERSIST WITH AN ISOLATED GUST UP
TO 15 KT POSSIBLE ACROSS NORTHERN TERMINALS DURING THE AFTERNOON
HOURS. SHORT TERM AND HREF GUIDANCE DOES SHOW SOME MID AND HIGH
LEVEL CLOUDINESS MOVING IN TO PARTS OF SOUTHEAST AND SOUTHERN
ARKANSAS AROUND 00Z TONIGHT. AN ISOLATED SHOWER OR THUNDERSTORM
IS POSSIBLE NEAR THE END OF THE PERIOD ACROSS FAR SOUTHEAST
ARKANSAS, WHICH COULD IMPACT KLLQ BUT CONFIDENCE REMAINS TOO LOW
TO PLACE INTO THE TAF DURING THIS CYCLE.
