DISCUSSION
ISSUED AT 231 AM CST WED NOV 19 2025
REGIONAL OBS DEPICT A COLD FRONT DRAPED ACROSS CNTRL AR THIS WED
MORNING. DEW POINT TEMPS VARIED BY A GREATER MARGIN THAN AIR TEMPS
ON EITHER SIDE OF THE FRONT BUT THE DIFFERENCES WERE EASILY APPARENT
NONETHELESS. SPOTTY SHOWERS FOR THE MOST PART HAD COME TO AN END
HOWEVER A STRAY SHOWER BEFORE DAWN IS STILL POSSIBLE ALONG AND AHEAD
OF THE FRONT.
TODAY, THE FRONT WILL BECOME STATIONARY OVER THE SRN 1/3RD OF THE
STATE BEFORE SLOWLY LIFTING NWRD AS A WARM FRONT THIS AFTERNOON.
HIGHS THIS AFTERNOON SHOULD RANGE FROM THE LOWER 70S N TO LOWER 80S
S. FOR REFERENCE, HIGHS SHOULD RANGE FROM THE UPPER 50S TO LOWER 60S
FOR THE DATE. GIVEN THIS WELL ABOVE AVERAGE TEMP PATTERN, RECORD
HIGHS COULD BE APPROACHED OR EXCEEDED ONCE AGAIN OVER THE SRN HALF
OF AR. RAIN CHANCES THROUGH THIS AFTERNOON SHOULD BE MINIMAL BUT
CLOUDS SHOULD INCREASE IN COVERAGE AHEAD OF THE NEXT STORM SYSTEM.
SYNOPTICALLY, A RIDGE AXIS WHICH IS SETTLED OVER THE REGION WILL
SHIFT EWRD THIS AFTERNOON AS A PROGRESSIVE DEEP TROUGH AND CLOSED
LOW MOVE INTO THE SWRN CONUS. LARGE SCALE FORCING FOR ASCENT WILL
BEGIN TO OVERSPREAD THE REGION AS EARLY AS WEDNESDAY NIGHT.
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE ANTICIPATED TO
INCREASE IN COVERAGE FROM THE W AS FORCING FOR ASCENT, LOW-LEVEL
MOISTURE ADVECTION, AND FAVORABLE LOW-LEVEL JET DYNAMICS ALL COME
TOGETHER ACROSS THE REGION. BY THURSDAY, A RATHER LARGE LOBE OF
ENERGY SHOULD EJECT FROM THE PARENT TROUGH, TRAVERSING ACROSS THE
PLAINS, AS A SHORT WAVE TROUGH. LEE CYCLOGENESIS IS ANTICIPATED TO
DEVELOP OVER THE PLAINS BENEATH SAID UPPER LEVEL FEATURE. CONTINUED
FORCING FOR ASCENT WILL PROMOTE PRECIPITATION ON THURSDAY INTO THE
FIRST HALF OF THE DAY ON FRIDAY ACROSS AR.
QPF TRENDS FOR LATE WEDNESDAY NIGHT THROUGH FRIDAY HAVE BEEN
TRENDING DOWNWARD IN REGARDS TO DETERMINISTIC AND ENSEMBLE DATA OVER
THE LAST SEVERAL DAYS. WHAT HAS REMAINED CONSISTENT WITHIN THE DATA
SET IS THE PREFERRED CORRIDOR OF HEAVIER RAINFALL. PROBABILISTIC
DATA DEPICTS 40%-60% CHANCE OF >2" RAINFALL ACROSS W AND NW AR
(CENTERED OVER W AR RIVER VALLEY) AND 40%->90% CHANCE OF >1"
RAINFALL ACROSS ROUGHLY THE NW 2/3RDS OF AR. ANALYZING CURRENT FLASH
FLOOD GUIDANCE WHICH PRESENTLY SITS AT 6HR FFG OF 3-5", 3HR FFG OF 3-
4", AND 1HR FFG OF 2-3", THE THREAT FOR WIDESPREAD FLASH FLOODING
APPEARS LOW. DETERMINISTIC FORECAST CALLS FOR 1-2" OF RAIN FOR THE
AFOREMENTIONED TIME SPAN ACROSS NW HALF OF AR (POSSIBLY UP TO 2-3"
IN PLACES), TO 1" OR LESS ACROSS THE SE HALF OF AR. THAT SAID, A
CORRIDOR OF TRAINING HEAVIER RAINFALL COULD STILL OCCUR, PROMPTING
SMALLER SCALE GREATER FLASH FLOOD CONCERNS.
BRIEF LULL IN ACTIVITY IS EXPECTED THROUGH MUCH OF THE WEEKEND AS
THE FORMER PARENT TROUGH EJECTS INTO THE ROCKIES. COMPACT RIDGING
WILL PRECEDE THE TROUGH WHICH WILL BRING NICE CONDITIONS TO AR FOR
ONE TO TWO DAYS. UNSETTLED CONDITIONS ARE ANTICIPATED TO RETURN BY
SUNDAY NIGHT AS AN UPPER TROUGH MOVES ACROSS THE PLAINS PROVIDING
LARGE SCALE FORCING FOR ASCENT TO OVERSPREAD THE REGION. SEVERAL KEY
FEATURES REMAIN AT LARGE SUCH AS DEPTH/ORIENTATION OF TROUGH,
LOCATION OF SURFACE LOW, AND LOW-LEVEL MOISTURE ADVECTION INTO THE
SURFACE LOW. THESE FEATURES WILL BE MONITORED OVER THE COMING DAYS
AND WILL IMPACT OVERALL EXPECTED RAINFALL AMOUNTS. DRIER WEATHER IS
ANTICIPATED BY WEDNESDAY IN THE WAKE OF A FRONTAL PASSAGE. MAIN
TAKEAWAY, QPF AMOUNTS COULD BE GREATER WITH THIS LATTER SYSTEM THAN
THE FORMER SYSTEM. TEMPS THROUGH THE PERIOD WILL LARGELY REMAIN
ABOVE CLIMATOLOGY FOR BOTH HIGHS AND LOWS.
