SYNOPTIC OVERVIEW AND CURRENT CONDITIONS: WATER VAPOR IMAGERY AND
UPPER LEVEL ANALYSIS SHOW GENERALLY WESTERLY FLOW ACROSS THE
CONUS WITH THE POLAR JET FROM OREGON INTO THE UPPER MIDWEST AND
INTO NEW ENGLAND ALONG THE U.S. CANADA BORDER. WITHIN THE WEAKER
FLOW SOUTH OF THE POLAR JET, SEVERAL EMBEDDED SHORTWAVES WERE
BRINGING CONVECTION TO PARTS OF THE MIDWEST AND THE MID
MISSISSIPPI VALLEY. AN UPPER LOW WITHIN THIS WEAK FLOW WAS
LOCATED JUST SOUTHWEST OF THE CWA AND WAS BRINGING A FAIRLY
LARGE AREAL COVERAGE OF LIGHT SHOWERS TO THE CWA WITH A FEW
EMBEDDED MODERATE TO HEAVIER SHOWERS NEARER TO THE CIRCULATION
IN THE SOUTHWEST CORNER OF MISSOURI.
TODAY-TONIGHT: THE UPPER LOW WILL SLOWLY TRAVERSE EASTWARD
ACROSS THE CWA WITH NUMEROUS SHOWERS AND A FEW EMBEDDED
THUNDERSTORMS OCURRING ACROSS THE AREA. WHILE OVERALL RAINFALL
AMOUNTS DO NOT LOOK OVERLY CONCERNING, POCKETS OF HEAVIER
CONVECTION GIVEN THE HIGH PRECIPITABLE WATER VALUES IN THE
MORNING AND AFTERNOON COULD LEAD TO SOME LOCALIZED FLOODING IF
THE STRONGER CELLS MOVE ACROSS THE SAME LOCATIONS. THE CLOUD
COVER AND RAINFALL WILL KEEP TEMPERATURES GENERALLY IN THE 70S
FOR HIGHS TODAY, DESPITE STARTING IN THE MID TO UPPER 60S. THE
PRECIPITATION COVERAGE SHOULD DIMINISH TONIGHT FROMW WEST TO
EAST AS THE LOW SHIFTS EASTWARD ACROSS AND OUT OF THE AREA BY
SATURDAY MORNING.
SATURDAY: UPPER LEVEL RIDGING BEGINS TO BUILD OVER THE SOUTHERN
ROCKIES INTO THE SOUTHERN HIGH PLAINS, HOWEVER THE EASTERN EDGE
OF THE RIDGE MAY ALLOW FOR SOME ADDITIONAL SHORTWAVE ENERGY TO
MOVE INTO THE AREA. WHILE MOST OF THE AREA SHOULD REMAIN RAIN
FREE ON SATURDAY INTO SATURDAY NIGHT, WE CAN'T RULE OUT SOME LOW
POPS SNEAKING INTO THE WESTERN CWA BY LATE SATURDAY INTO
SATURDAY NIGHT. HIGHS SHOULD REACH THE LOW TO MID 80S IN THE
EAST AND THE MID TO UPPER 80S IN THE WEST.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
ISSUED AT 217 AM CDT FRI JUN 13 2025
UPPER LEVEL PATTERN LOOKS MESSY FOR MUCH OF THE UPCOMING WEEK.
INITIALLY, THE UPPER RIDGE AXIS WILL BE SOUTHWEST OF THE AREA
WITH SOME NORTHWEST FLOW ON THE EASTERN SIDE OF THE RIDGE AXIS
WHICH MAY BRING SOME SHORTWAVE ENERGY THROUGH THE AREA EARLY IN
THE WEEK. WHILE WE WON'T SEE CONTINUOUS RAIN, WE WILL MAINTAIN
LOW END POPS(15-40%) FOR EARLY IN THE WEEK.
A DEEPER TROUGH LOOKS TO PUSH THROUGH THE WESTERLIES AROUND
MIDWEEK (WED/THU) WITH RAIN CHANCES (20-50%).
WITH TEMPERATURES RISING INTO THE UPPER 80S TO AROUND 90 AND DEW
POINTS IN THE 70S, WE COULD SEE HEAT INDEX VALUES IN THE MID 90S
TO AROUND 100 TUE AND WED.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/
ISSUED AT 537 AM CDT FRI JUN 13 2025
FOR THE 12Z TAFS, AN UPPER LOW WAS LOCATED OVER THE CWA WITH
SHOWERS OCCURRING ACROSS MUCH OF THE AREA. EMBEDDED HEAVIER
SHOWERS WERE DROPPING VISIBLITY INTO THE 1 1/2 TO 2 MILE RANGE,
BUT LIGHTER SHOWERS WERE GENERALLY IN THE 4 TO 6+ RANGE. WILL
MAINTAIN SOME MVFR AND IFR THIS MORNING WITH IMPROVEMENT AT THE
TAF SITES DURING THE AFTERNOON AS THE LOW GRADUALLY SLIDES EAST.
CONVECTION SHOULD BECOME MORE SCATTERED BY LATE IN THE DAY, THEN
DIMINISHING TONIGHT. MAY SEE SOME FOG DEVELOP OVERNIGHT,
ESPECIALLY AT BBG WHERE WE ARE DROPPING TO 1 MILE AND 300 FEET
AT THIS TIME.
