ISSUED AT 253 PM CDT SUN SEP 27 2026
ALOFT THIS AFTERNOON, A H500 LOW LOCATED OVER THE US EAST COAST
CONTINUES TO MOVE UP THE EASTERN SEABOARD THIS AFTERNOON. A MID
LEVEL RIDGE ENCOMPASSES THE WESTERN PORTION OF THE CENTRAL AND
SOUTHERN PLAINS REGIONS WITH DEEPENING TROUGH MOVING ASHORE ONTO
THE US WEST COAST REGION. THE AFOREMENTIONED UPPER LEVEL FEATURES
ARE PROMOTING NORTHWEST FLOW OVER THE STATE WITH LIGHT EAST TO
NORTHEAST WINDS ACROSS THE STATE. A SUBTLE WEAK SHORTWAVE
CONTINUES TO TREK SOUTHEAST ACROSS ARKANSAS LEADING TO A COMPLEX
OF SHOWERS ACROSS NORTHWEST ARKANSAS WITH ISOLATED SHOWERS
ELSEWHERE WITHIN THE STATE. SHOWER AND ISOLATED THUNDERSTORM ACTIVITY
WILL CONTINUE TO DIMINISH THROUGH THE EVENING HOURS ACROSS
ARKANSAS.
AS WE HEAD INTO THE FIRST HALF OF THE WORK WEEK, THE H500 RIDGE
AXIS WILL GRADUALLY MOVE EASTWARD TOWARD THE STATE PROMOTING DRY
AND WARM CONDTIONS WITHIN AFTERNOON HIGHS RUNNING ROUGHLY 5 TO 10
DEGREES ABOVE NORMAL LATE SEPTEMBER ACROSS ARKANSAS.
DURING THE LATTER PART OF THE WEEK, A DEEPENING AND DIGGING
TROUGH WITH CUT OFF LOW WILL CONTINUE TO PROGRESS TO JUST SOUTH OF
THE FOUR CORNERS REGION ON MONDAY. BOTH THE ECMWF AND GFS SHOWS
THE REMNANTS OF HURRICANE POLO MOVING NORTH OUT OF THE MEXICAN
STATE OF SONORA INTO THE DESERT SOUTHWEST BEFORE BEING ABSORBED
INTO THE TROUGH SOMETIME MONDAY NIGHT INTO TUESDAY. THE CUT OFF
LOW/UPPER TROUGH WILL GRADUALLY PROGRESS EASTWARD INTO THE CENTRAL
AND SOUTHERN PLAINS DURING THE LATTER PART OF THE WEEK. AHEAD OF
THE TROUGH, THE SUBTROPICAL JET WILL AID IN BRINGING PLENTIFUL
MOISTURE OFF THE PACIFIC INTO THE CENTRAL AND SOUTHERN PLAINS.
THIS WILL LEAD TO AN INCREASE IN RAIN CHANCES DURING THE LATTER
PART OF THE WEEK INTO THE WEEKEND ACROSS THE STATE. WITH
ENSEMBLES AND THE ECMWF CONTINUING TO SHOW A STRENGTHENING RIDGE
OVER THE SOUTHEAST US AHEAD OF TROUGH OVER THE CENTRAL AND
SOUTHERN PLAINS, CONFIDENCE REMAINS BELOW AVERAGE WITH REGARDS TO
POTENTIAL RAINFALL AMOUNTS ACROSS THE STATE. AS MENTIONED
YESTERDAY AND DURING THIS MORNING'S DISCUSSION, CONFIDENCE REMAINS
HIGHEST FOR APPRECIABLE RAINFALL ACROSS PARTS OF NORTHWEST AND
WESTERN ARKANSAS DURING THE LATTER PART OF THE WEEK INTO THE
WEEKEND. BOTH THE NBM 50TH PERCENTILE AND ECMWF ENSEMBLE SHOWS 1
TO 2 INCHES AMOUNTS ACROSS WESTERN AND NORTHWEST ARKANSAS, WHILE
THE GFS ENSEMBLE AND NBM 90TH PERCENTILE SHOWING AMOUNTS OF 2 OR
INCHES STATEWIDE WITH AMOUNTS OF 3+ INCHES ACROSS PARTS OF WESTERN
AND NORTHWEST ARKANSAS. WILL CONTINUE TO MONITOR THE FORECAST AND
MAKE CHANGES TO THE FORECAST AS FORECAST CONFIDENCE HOPEFULLY
STARTS TO INCREASE CLOSER TO THE EVENT.
