ISSUED AT 243 PM CDT MON APR 6 2026
CLOUDS HAVE MOSTLY CLEARED THE REGION WITH SOME LINGERING ACROSS
WESTERN WI UNDER THE CYCLONIC INFLUENCE OF THE DEPARTING LOW
PRESSURE SYSTEM. SURFACE HIGH PRESSURE WILL BUILD SOUTHEAST TO
THE UPPER MIDWEST TONIGHT. A DRY ATMOSPHERE, LIGHT WINDS, AND
CLEAR SKIES SHOULD ALLOW MOST LOCATIONS TO DROP INTO THE TEENS.
SOME SINGLE DIGITS ARE POSSIBLE IN AREAS OF LINGERING SNOWPACK.
THE HIGH WILL BE CENTERED OVER THE GREAT LAKES BY MIDDAY TUESDAY
WHEN RETURN FLOW WILL BE WELL UNDERWAY LOCALLY. MOISTURE
TRANSPORT WILL INCREASE TUESDAY EVENING ACROSS IOWA AND
SOUTHWESTERN MN THANKS TO A STRENGTHENING 50-60 KT LLJ. THIS
SHOULD ALLOW FOR SHOWER DEVELOPMENT MID TO LATE EVENING ACROSS
EASTERN MN, GROWING IN COVERAGE OVERNIGHT ACROSS WI. THERMAL
PROFILES ARE MARGINALLY SUPPORTIVE OF SNOW INITIALLY, BUT MILDER
LOW LEVEL PROFILES OVERNIGHT WILL ALLOW ANY MIXED PRECIP TO
TURN TO RAIN. AMOUNTS WILL BE LIGHT, PERHAPS A TENTH OF AN INCH
IN PARTS OF WI.
MEANWHILE, AN AREA OF LOW PRESSURE WILL TRACK EAST ALONG THE
U.S./CANADIAN BORDER TUESDAY NIGHT, REACHING THE MN/ON BORDER
AREA WEDNESDAY NIGHT. LOW LEVEL FLOW WILL STRENGTHEN WEDNESDAY
AHEAD OF THE APPROACHING COLD FRONT. FORECAST SOUNDINGS SHOW
GOOD POTENTIAL FOR 30-40 KT GUSTS WEDNESDAY AFTERNOON.
TEMPERATURES WILL ALSO BE MILDER, IN THE 50S, ACROSS WESTERN MN
BEFORE A LATE MORNING COLD FROPA. A FEW MORE HOURS OF HEATING
FARTHER EAST COULD SEND EASTERN/SOUTHERN MN AND WI TO REACH THE
LOW TO MID 60S BEFORE THE FRONT PASSES THROUGH EARLY TO MID
AFTERNOON. MOISTURE TRANSPORT WILL BE DISPLACED EAST OFF THE
FRONT, SO MOST OF THE FROPA COULD BE DRY UNTIL IT REACHES FAR
EASTERN MN AND WI. ANOTHER TENTH OR TWO OF RAIN IS POSSIBLE
ACROSS WI, WITH LITTLE, IF ANY, ACROSS MN. COOLER AND DRIER AIR
FOLLOWS FOR THURSDAY AND FRIDAY WITH THE FRONT STALLED ACROSS
THE OH AND MID MS VALLEY.
BY THIS WEEKEND, A LARGE TROUGH ACROSS THE WESTERN U.S. AND A
BUILDING RIDGE ACROSS THE CENTRAL AND EASTERN U.S WILL PRODUCE
AN ACTIVE SOUTHWEST FLOW PATTERN ACROSS THE PLAINS AND UPPER
MIDWEST. BROAD WARM AIR ADVECTION NORTHWARD ACROSS THE PLAINS
WILL BRING ANOMALOUSLY MOIST AIR IN SATURDAY NIGHT AND SUNDAY.
PWATS BETWEEN 200-300 PERCENT ABOVE NORMAL ARE POSSIBLE. SHOWERS
AND A FEW THUNDERSTORMS WILL BREAK OUT SATURDAY NIGHT WITH AN
INCREASING 50 KT LLJ BY LATE EVENING. LAPSE RATES WILL BE POOR
WHICH SHOULD LIMIT ANY SEVERE POTENTIAL, BUT THE SHOWERS WILL BE
EFFICIENT. DEPENDING ON THE RATE OF DISSIPATION OF THE SHOWERS
SUNDAY MORNING, IT MAY BECOME QUITE WARM AHEAD OF THE NEXT
ROUND. DEW POINTS IN THE LOW 60S AND HIGHS IN THE 70S ARE
APPEARING MORE AND MORE LIKELY SUNDAY. 80S ARE POSSIBLE, BUT
WOULD REQUIRE SUN TO BREAK OUT. LOW PRESSURE OVER THE NORTHERN
PLAINS SUNDAY WILL SPARK OFF THE NEXT ROUND LATE SUNDAY INTO
MONDAY. BETTER LAPSE RATES THIS TIME MAY ALLOW FOR MORE
WIDESPREAD THUNDERSTORM ACTIVITY. THE LOW WILL WEAKEN AND PASS
TO THE EAST EARLY NEXT WEEK. TEMPERATURES MONDAY ARE OF LOW
CONFIDENCE AT THIS POINT WITH THE SURFACE FRONT LIKELY BISECTING
PARTS OF THE AREA AROUND THAT TIME.
AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/
ISSUED AT 1214 AM CDT TUE APR 7 2026
CLEAR SKIES AND LIGHT, VARIABLE WINDS OVERNIGHT. MID-HIGH LEVEL
CLOUDS WILL START TO STREAM IN AROUND MIDDAY AHEAD A LOW
PRESSURE SYSTEM. AS CLOUD COVER INCREASES, MVFR LEVEL CIGS MAY
DEVELOP AS EARLY AS THIS EVENING FOR WESTERN AND CENTRAL MN
SITES. WINDS WILL INCREASE OUT OF THE SSE AFTER SUNRISE, AND
BECOME BREEZY BY THE AFTERNOON.
KMSP...VFR CONDITIONS EXPECTED THROUGH DAY, WITH INCREASING
CLOUD COVER TONIGHT. MVFR CIGS ARE MOST LIKELY TO ARRIVE AROUND
05-07Z, WITH A CHANCE FOR LIGHT RAIN EARLY IN THE MORNING. THE
LATEST TRENDS SUGGEST MSP STAYS DRY TO START THE DAY WEDNESDAY,
SO THE PROB30 MAY BE REMOVED AS CONFIDENCE INCREASES FOR NO
PRECIPITATION.
