SHORT TERM /THROUGH TONIGHT/
ISSUED AT 127 PM CDT SAT JUN 6 2026
A SURFACE LOW IS CHURNING TO OUR WEST OVER OK TODAY AND THAT'S
WHERE THE HEAVIEST RAIN HAS FALLEN. HOWEVER, SOUTHERN MO HAS
SEEN SOME RAIN TODAY, BUT RAINFALL ACCUMULATIONS HAVE STAYED
LOWER (~ 1 INCH) AND NO FLOODING HAS OCCURRED QUITE YET.
THOUGH, WITH RAIN THAT HAS MOVED THROUGH, VISIBILITIES HAVE
DROPPED TO 1 TO 2 MILES WITHIN THE HEAVIER RAIN BANDS. HEAVIEST
BANDS AND LIGHTNING HAS STAYED CLOSER TO THE SURFACE LOW DOWN TO
OUR SOUTHWEST. THERE WILL BE BRIEF PERIODS OF DRY WEATHER
ESPECIALLY LATER THIS EVENING AS THE CHANCE FOR RAIN DROPS TO
20-40%. THEN, A SMALL LOW-LEVEL JET GETS GOING TONIGHT AFTER
MIDNIGHT OVER FAR SW MO AND SE KS AND STARTS TO INCREASE OUR
RAIN CHANCES AGAIN IN THAT AREA OVERNIGHT (50-60%). THERE MAY BE
MINOR FLOODING THAT OCCURS TODAY ESPECIALLY IN URBAN AREAS OR
LOW- LYING FLOOD PRONE AREAS.
THE REMAINDER OF TODAY WILL BE CLOUDY WITH HIGHS REACHING THE
UPPER 70S. LOWS TONIGHT WILL BE IN THE UPPER 60S WITH LIGHT
SOUTHERLY WINDS.
LONG TERM /MONDAY THROUGH SATURDAY/
ISSUED AT 127 PM CDT SAT JUN 6 2026
MORE RAIN IS ON THE WAY ON SUNDAY AS THE LOW PRESSURE SYSTEM
SLOWLY PUSHES NORTHEAST THROUGH THE DAY. TOMORROW FEATURES OUR
HIGHEST CHANCE FOR FLOODING AS THE TROUGH EJECTS AN ABUNDANCE OF
MID-LEVEL VORTICITY INTO OUR AREA. THIS WILL ENHANCE THE LIFT
FOR EVEN HIGHER RAIN RATES OVER OUR AREA TOMORROW. WE WILL
STILL MESSAGE THE THREAT FOR 1-3 IN/HR RATES WITH THIS ACTIVITY
WHICH IS THE REASON FOR THE ISSUANCE OF THE FLOOD WATCH. THERE
WERE ALREADY 2-3 IN/HR RATES IN THE ACTIVITY TODAY OVER OK, AND
WE WILL SEE SIMILAR CONVECTIVE PROCESSES TOMORROW. THIS WATCH
WAS ISSUED DUE TO THE HIGH RAIN RATES EXPECTED AS OPPOSED TO
OVERALL RAINFALL TOTALS. THE FLOOD WATCH AS BEEN ISSUED MOSTLY
FOR COUNTIES ALONG AND WEST OF HIGHWAY 63 FROM 1 PM SUNDAY
THROUGH 1 PM MONDAY. EVEN THOUGH RAIN WILL START EARLIER THAN
THIS TIMEFRAME, THIS IS WHEN THE RISK FOR FLASH FLOODING IS AT
ITS PEAK. NOT ALL THE COUNTIES IN THE WATCH WILL SEE FLASH
FLOODING, AND THERE COULD BE AREAS OUTSIDE OF THE WATCH THAT DO
END UP SEEING LOCALIZED FLASH FLOODING. AS FAR AS RAINFALL
TOTALS GO, WE ARE EXPECTING 1-3 INCHES OF RAIN WITH LOCALIZED
AMOUNTS UP TO 5 INCHES.
SPC HAS INTRODUCED A SMALL AREA OF A MARGINAL RISK (1/5) OVER
SE KS AND SW MO MAINLY FOR A TORNADO RISK. THIS RISK SPAWNS FROM
THE DECENT AMOUNT OF SHEAR AND SRH (200-300 M2/S2) OVER THE
AREA DUE TO THE SURFACE LOW. THIS TORNADO RISK IS A LOW AND VERY
CONDITIONAL THREAT. SHEAR AND INSTABILITY HAVE TO LINE UP
PERFECTLY TO GET THIS RISK TO COME TO FRUITION. BUT, THE LOW-END
RISK IS THERE TOMORROW AND WE WILL HAVE TO MONITOR THAT THREAT.
ANOTHER SHORTWAVE MOVES THROUGH THE AREA TO START THE WEEK AND
BRINGS RAIN CHANCES FOR MONDAY AND TUESDAY. BY MID-WEEK, HIGH
PRESSURE SETS IN ONCE AGAIN. ABOVE NORMAL TEMPERATURES AND
HUMIDITY NEXT WEEK WILL LEAD TO HEAT INDEX VALUES IN THE MID-90S
TO LOWER 100S. FIRST HEAT OF THE SEASON AND WARM NIGHTTIME
TEMPERATURES MAY HEIGHTEN HEAT-RELATED IMPACTS. TAKE CAUTION IF
YOU ARE SENSITIVE TO HEAT.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
ISSUED AT 1240 AM CDT SUN JUN 7 2026
A MESSY FORECAST IS IN STORE FOR THE 06Z TAF PERIOD AS SATELLITE
IMAGERY CONTINUES TO SHOW A SYSTEM SPIN AWAY IN KANSAS/OKLAHOMA.
RADAR IMAGERY SHOWS A FEW LIGHT SHOWERS LIFTING NORTH IN THE
VICINITY OF SGF AND BBG, WHICH MAY IMPACT VISIBILITIES AT THE
TAF SITES THROUGH 12Z. AT THE SAME TIME, CIGS HAVE BEEN REPORTED
TO BE MVFR AT JLN AND BBG, NEARING IFR. THESE WILL CONTINUE TO
FLUCTUATE THROUGH AT LEAST 18Z BEFORE DAYTIME MIXING RAISES CIGS
ABOVE MVFR THRESHOLDS.
AFTER 12Z, NUMEROUS SMALL-IN-AREA SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO DEVELOP ACROSS THE REGION, CREATING A PROB30 FOR
THUNDERSTORMS THROUGHOUT THE ENTIRE PERIOD. MODEL GUIDANCE IS
HONING ON A POTENTIAL WEAKLY ORGANIZED LINE OF STORMS MOVING
THROUGH SGF AND BBG BETWEEN 17-21Z. HAVE OPTED TO PUT A TEMPO
GROUP HERE FOR THE GREATER CONFIDENCE IN STORM IMPACT.
WITH ANY OF THE SHOWERS AND STORMS, HEAVY DOWNPOURS AND
LIGHTNING WILL BE THE MAIN RISK, WITH VISIBILITY DROPPING DOWN
TO A MILE OR LOWER AT TIMES, IF IMPACTED DIRECTLY.
OTHERWISE, WINDS WILL BE AT 8-13 KTS OUT OF THE SOUTHEAST FOR
THE ENTIRE PERIOD.
