DISCUSSION

SATELLITE THIS AFTERNOON SHOWS A PRONOUNCED MCV OVER SOUTHWEST
MISSOURI NORTH OF A STATIONARY BOUNDARY THAT IS DRAPED OVER
NORTHERN ARKANSAS. THE BOUNDARY ALONG WITH OUTFLOW SENT OUT FROM A
DECAYING MCS NOW OVER NORTH CENTRAL TEXAS IS AIDING IN INITIALIZING
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS OVER THE STATE THIS
AFTERNOON. HI-RES CAMS THIS AFTERNOON CONTINUES THIS TREND WITH
SOME UPTICK IN SHOWER AND THUNDERSTORM ACTIVITY POSSIBLE AFTER 23Z
SUNDAY THROUGH 06Z MONDAY OVER PORTIONS OF CENTRAL AND NORTHEAST
ARKANSAS. A FEW STRONG STORMS ARE POSSIBLE THIS EVENING WITH SOME
GUIDANCE SHOWING CAPE VALUES BETWEEN 1500-2000J/KG OVER CENTRAL
AND NORTHEAST ARKANSAS WITH CAPE IN EXCESS OF 3000 OVER SOUTHERN
ARKANSAS. AN ANALYSIS OF THE 12Z LZK SOUNDING SHOWS AROUND 15KT OF
BULK SHEAR WITH HIGHER SHEAR VALUES CLOSER TO 20-30 KNOTS NEAR
THE MCS. THE PRIMARY HAZARD THIS AFTERNOON AND INTO THE EVENING
HOURS WILL BE STRONG GUSTY WINDS AND STORMS MAY BRIEFLY REACH
SEVERE LIMITS WITH SOME BRIEF LOCALIZED FLASH FLOODING ALSO
POSSIBLE, BUT NO ORGANIZED SEVERE WEATHER IS EXPECTED.
AS WE HEAD INTO MONDAY AND TUESDAY, UPPER SHORT WAVE TROUGH AXIS
WILL MOVE OVER THE STATE ON MONDAY WITH ADDITIONAL CHANCES FOR
SHOWERS AND THUNDERSTORMS OVER THE STATE. AS WILL BE THE CASE
THIS AFTERNOON AND EVENING AND WAS YESTERDAY, A FEW STORMS COULD
BE STRONG TO BRIEFLY SEVERE WITH DAMAGING WINDS BEING THE PRIMARY
THREAT AND SOME LOCALIZED FLASH FLOODING IS ALSO POSSIBLE. BY
MONDAY NIGHT, TROUGH AXIS WILL BE OVER FAR EASTERN ARKANSAS WITH
ISOLATED TO SCATTERED CHANCES FOR SHOWERS AND THUNDERSTORMS OVER
EASTERN AND SOUTHEAST ARKANSAS. BY TUESDAY, OVER THE SOUTHERN
ROCKIES WITH A SHORT WAVE TROUGH INVOF TENNESSEE AND OHIO RIVER
VALLEYS. THIS WILL HELP TO PROMOTE WEAK NORTHWEST FLOW OVER THE
STATE THROUGH TUESDAY AFTERNOON. BY TUESDAY NIGHT, FLOW OVER THE
STATE WILL BECOME MORE WESTERLY BEFORE A SHORT WAVE TREKS EASTWARD
ACROSS THE AREA KICKING OFF ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS AROUND WEDNESDAY AFTERNOON THROUGH THURSDAY. NO
ORGANIZED SEVERE WEATHER IS EXPECTED, BUT A STRONG STORM OR TWO IS
NOT OUT OF THE QUESTION OVER FAR NORTHERN ARKANSAS WITH THE
PRIMARY HAZARD BEING DAMAGING WINDS.
BY FRIDAY INTO THE WEEKEND, RIDGING OVER THE DESERT SOUTHWEST WILL
EXPAND EASTWARD AND AMPLIFY AND PUSH EASTWARD TOWARD THE STATE
WITH THE RIDGE CENTERED OVER THE MID SOUTH BY SATURDAY. THIS WILL
HELP TO PROMOTE DRY CONDITIONS BUT ALSO HOT AND HUMID CONDITIONS
ACROSS THE AREA THROUGH DURING THE FRIDAY-SUNDAY TIME FRAME AS
SOUTH/SOUTHWEST SURFACE FLOW SETS UP OVER THE STATE. AT THIS TIME,
PORTIONS OF CENTRAL AND SOUTHERN ARKANSAS APPEAR LIKELIEST TO
COME CLOSE OR MEET CRITERIA THRESHOLD FOR HEAT HEADLINES DURING
THE FRIDAY THROUGH SUNDAY TIME FRAME. IF MODEL TO CONDITION
CONSISTENCY CONTINUES, THEN HEAT HEADLINES MAY BE NEEDED AT SOME
POINT DURING THE AFOREMENTIONED TIME FRAME.
TEMPERATURES ON MONDAY WILL BE AROUND 5 OR SO DEGREES BELOW
NORMAL, THEN QUICKLY REBOUND TO A FEW DEGREES ABOVE NORMAL THROUGH
THE REST OF THE FORECAST PERIOD.
