ABNORMALLY HOT AND DRY CONDITIONS WILL CONTINUE ACROSS MUCH OF AR
BENEATH AN EXPANSIVE UPPER RIDGE. THIS RIDGE IS EXPECTED TO REMAIN
NEARLY STATIONARY OVER THE SRN PLAINS THROUGH MIDDLE PART OF THIS
WEEK. RESULTANT LARGE SCALE FORCING FOR SUBSIDENCE SHOULD INHIBIT
WIDESPREAD ORGANIZED CONVECTION THROUGH AT LEAST WEDNESDAY.
CURRENTLY, A WEAK BACKDOOR COLD FRONT WAS MOVING ACROSS THE STATE
FROM NE TO SW. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE
EXPECTED TO DEVELOP OVER PORTIONS OF SW/W/S AR LATER THIS
AFTERNOON ALONG AND AHEAD OF THE FRONTAL BOUNDARY AS IT BECOMES
NEARLY STATIONARY OVER THE ARKLATEX'S REGION. BRIEF GUSTY WINDS
WOULD BE THE MAIN THUNDERSTORM HAZARD WITH ANY STRONG STORM.
TEMPS OVER SW/W/S AR WILL BE HOT THANKS TO COMPRESSIONAL WARMING
AHEAD OF SHOWER AND THUNDERSTORM DEVELOPMENT. ACROSS THIS PORTION
OF THE STATE, HIGHS MAY RANGE FROM 100 TO 105 DEGREES. A HEAT

THROUGH THIS EVENING FOR HEAT INDEX VALUES UP TO 110 DEGREES.
ELSEWHERE, WINDS WILL BE E/NERLY BEHIND THE FRONT WITH HIGHS
TOPPING OUT IN THE LOWER TO MID 90S AND HEAT INDEX VALUES PEAKING
BELOW 105 DEGREES AS SLIGHTLY DRIER AIR ADVECTS INTO THE STATE
FROM THE NE. DRIER AIR WILL STICK AROUND INTO TUESDAY FOR A LARGE
PART OF THE STATE BEFORE WINDS SWITCH TO THE S/SW ON WEDNESDAY
WITH THE RETREAT OF AFOREMENTIONED FRONT.
LONG RANGE ENSEMBLE GUIDANCE IS DEPICTING WEAKENING/RETROGRADING
OF THE RIDGE IN THE THURSDAY THROUGH SATURDAY TIME FRAME WITH
BROAD NW FLOW BECOMING ESTABLISHED. UNSETTLED WEATHER MIGHT MAKE
A RETURN ON THURSDAY THROUGH SATURDAY WHILE ALSO INTRODUCING
SLIGHTLY COOLER TEMPS TO THE STATE. HIGHEST POP CHANCES WILL BE
OVER THE NRN HALF OF AR EACH OF THESE DAYS. UNFORTUNATELY SRN HALF
OF AR MAY NOT SEE MUCH APPRECIABLE RAINFALL DURING THESE THREE
DAYS. BEYOND THIS PERIOD, THE RIDGE IS EXPECTED TO SLOWLY BUILD
