TODAY AND TONIGHT
DRY EASTERLY WINDS HAVE LOWERED DEW POINTS INTO THE MID- AND
UPPER 40S ACROSS CENTRAL, WEST-CENTRAL AND SOUTHWEST WISCONSIN
EARLY THIS MORNING. THIS DRIER AIR WILL CONTINUE TO SPREAD WEST
INTO SOUTHEAST MINNESOTA AND NORTHEAST IOWA THIS MORNING. AS A
RESULT, SHOWERS AND STORMS WILL REMAIN PRIMARILY NORTH OF
INTERSTATE 90 AND CLOSER TO INTERSTATE 35 THIS MORNING. THIS IS
DUE TO HIGHER DEW POINTS IN THESE AREAS.
AS A SHORTWAVE MOVES EAST INTO WESTERN WISCONSIN THIS AFTERNOON,
THE DEW POINTS SOUTH OF INTERSTATE 94 WILL CLIMB INTO THE LOWER
AND MID 60S. IN ADDITION TO THIS SHORTWAVE, THERE WILL BE
ANOTHER SHORTWAVE TROUGH MOVE NORTHEAST THROUGH THE MID
MISSISSIPPI RIVER INTO THE OHIO AND TENNESSEE RIVER VALLEYS.
THESE WILL RESULT IN SCATTERED SHOWERS AND STORMS THIS AFTERNOON
AND EVENING. SOUNDINGS CONTINUE TO SHOW WEAK SHEAR AND SKINNY
CAPES, SO THE SEVERE WEATHER THREAT CONTINUES LOOKS TO BE LOW
THIS AFTERNOON AND EVENING.
SATURDAY AFTERNOON AND EVENING
WHILE THE 500 MB RIDGE BUILDS NORTHEAST INTO THE REGION, THERE
WILL BE LIMITED CAPPING AHEAD OF YET ANOTHER SHORTWAVE TROUGH.
THIS WILL RESULT IN ANOTHER ROUND OF SCATTERED SHOWERS AND
STORMS. SOUNDINGS CONTINUE TO SHOW WEAK SHEAR AND SKINNY CAPES,
SO THE SEVERE WEATHER THREAT LOOKS TO BE A LOW THREAT.
SUNDAY THROUGH TUESDAY
THERE WILL BE PERIODIC SHORTWAVE TROUGHS MOVING ALONG THE NORTH
AND NORTHEAST PERIPHERY OF A LONGWAVE RIDGE. THIS WILL BRING
PERIODIC SHOWERS AND STORMS TO THE REGION. IT CURRENTLY LOOKS
LIKE THE 0-3 AND 0-6 KM SHEAR WILL BE ON THE WEAK SIDE.
HOWEVER, IF THERE HAPPENS TO BE A STRONGER MID-LEVEL JET ALOFT,
THIS COULD POTENTIALLY RESULT IN THE POTENTIAL FOR SOME SEVERE
WEATHER.
WEDNESDAY THROUGH THURSDAY
THIS LOOKS TO BE A BETTER CHANCE OF SHOWERS AND STORMS AS A
LONGWAVE TROUGH MOVES THROUGH THE REGION. SEVERE WEATHER CHANCES
REMAIN UNCERTAIN DO TO QUESTIONS ON INSTABILITY.
AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
ISSUED AT 1153 AM CDT FRI JUN 13 2025
VFR TO HIGH-END MVFR CONDITIONS CURRENTLY PRESENT ACROSS THE
AREA. MVFR CIGS SHOULD LIFT TO THE NORTH THROUGH THE AFTERNOON
WITH VFR CONDITIONS AT THE TERMINALS. MVFR CLOUDS ARE EXPECTED
TO RETURN FOR THE RST TERMINAL LATE OVERNIGHT INTO EARLY
TOMORROW MORNING. CLOUDS WILL BE SCATTERED FOR A FEW HOURS
BEFORE THE DECK BECOMES MORE BROKEN AROUND 12Z. TIMING ON THESE
MVFR CIGS WILL LIKELY NEED TO BE HONED-IN WITH FUTURE PACKAGE
UPDATES. LOW PRECIPITATION CHANCES REMAIN THROUGH MUCH OF THE
PERIOD BUT ACTIVITY LOOKS SCATTERED ENOUGH AND CONFIDENCE IS
STILL TOO LOW TO INCLUDE A MENTION FOR NOW. WINDS OUT OF THE
EAST WILL CONTINUE INTO THE OVERNIGHT HOURS BETWEEN 5-12 KTS
BEFORE BECOMING MORE SOUTHERLY THROUGH THE MORNING HOURS
TOMORROW.
