SHORT TERM
(THE REST OF TONIGHT)
ISSUED AT 932 PM CDT THU JUN 26 2025
SCATTERED SHOWERS ALONG WITH A FEW STORMS CONTINUED TO SPREAD
EASTWARD INTO/ACROSS EASTERN OKLAHOMA AS OF MID EVENING AHEAD OF
A WEAK UPPER LEVEL TROF AXIS/WIND SHIFT SLOWLY MOVING ACROSS
CENTRAL OKLAHOMA. MID LEVEL LAPSE RATES ALONG WITH INCREASING CIN
COMBINED WITH THE LOSS OF DAYTIME HEATING HAS WEAKENED THE
THUNDERSTORM POTENTIALS AS LIGHTNING ACTIVITY HAS DECREASED OVER
THE PAST COUPLE OF HOURS OVER CENTRAL OKLAHOMA. IN RESPONSE,
SEVERE POTENTIALS HAVE ALSO WEAKENED THROUGH THE EVENING HOURS.
THE STRONGEST STORMS WERE JUST NORTH OF THE CWA INTO SOUTHEAST
KANSAS.
OVERNIGHT TONIGHT, RAIN AND STORM CHANCES WILL REMAIN FORECAST
ACROSS NORTHEAST OKLAHOMA WITH LESSER POTENTIAL INTO SOUTHEAST
OKLAHOMA AND FAR NORTHWEST ARKANSAS WITH THE WEAK UPPER LEVEL
DISTURBANCE MOVING INTO THE REGION. THE GREATER THUNDER CHANCES
EXIST OVER NORTHEAST OKLAHOMA, WHERE A WEAK SURFACE BOUNDARY FROM
ONGOING STORMS IN SOUTHERN KANSAS COULD SAG INTO THE CWA.
ISOLATED POTENTIAL FOR A STRONG TO MARGINALLY SEVERE STORM FOR
STRONG WINDS REMAINS POSSIBLE WITH THIS ACTIVITY.
TEMPS TONIGHT SHOULD AGAIN REMAIN IN THE 70S ACROSS THE MAJORITY
OF THE CWA DUE TO CONTINUED SOUTHERLY LOW LEVEL FLOW TRANSPORTING
MOISTURE INTO THE REGION. FOR THE EVENING UPDATE, HAVE ADJUSTED
POPS BASED ON THE MENTIONED ABOVE AND TWEAKED HOURLY TEMP/DEWPOINT
TRENDS TONIGHT TO ACCOUNT FOR LATEST OBS. THE REST OF THE
FORECAST SEEM TO BE IN GOOD SHAPE AT THIS TIME.
LONG TERM
(TONIGHT THROUGH THURSDAY)
ISSUED AT 140 PM CDT THU JUN 26 2025
WEAK SFC BOUNDARY SLIDES INTO THE FORECAST AREA TOMORROW WHILE
REMNANT TROUGHING REMAINS ALOFT AS THE UPPER RIDGE HAS WEAKENED.
A BROADER EXPANSE OF DEEP MOISTURE WILL ALSO BE PRESENT AND
EXPECTATION IS SHOWER AND STORMS WILL BE ONGOING EARLY FRIDAY
STEADILY EXPAND IN COVERAGE THROUGH THE AFTERNOON WITH A DRIFT TO
THE EAST AND SOUTH. ANY STRONGER STORM WILL BE CAPABLE OF LOCALLY
GUSTY WINDS. HEAVY DOWNPOURS SHOULD BE EXPECTED WITH THE SLOW
STORM MOTIONS.
STORM CHANCES CONTINUE ON SATURDAY BUT OVERALL LESSER COVERAGE IS
EXPECTED. ANOTHER GLANCING INFLUENCE FROM A PASSING WAVE ALOFT IS
LIKELY TO INCREASE SHOWER AND STORM COVERAGE SUNDAY INTO MONDAY.
OVERALL TEMPS AND AFTERNOON HEAT INDEX VALUES EXPECTED TO REMAIN
NEAR SEASONAL NORMALS. OUTDOOR ACTIVITIES SHOULD BE MINDFUL OF
LIGHTNING SAFETY THROUGH THE WEEKEND.
