SOUTHERLY WINDS WILL BEGIN TO PICK UP ACROSS SOUTHERN WISCONSIN

PATTERSON
SHORT TERM
ISSUED 1110 PM CDT MON OCT 5 2026
TONIGHT THROUGH WEDNESDAY NIGHT:
WE CONTINUE TO MONITOR ONGOING PRECIP IN NORTHERN WI TRACKING
EAST SOUTHEAST THROUGH THE STATE WITH ONLY A VERY MINOR CHANCE
THAT THIS CLIPS FAR NORTHEASTERN PORTIONS OF THE CWA. THIS COMES
ON THE BACKS OF A LLJ WITH SOME WAA AND INCREASED MOISTURE.
WHILE THIS FORCING WILL IN PART MOVE OVER THE AREA THE MOISTURE,
PARTICULARLY IN THE LOW LEVELS (850MB), WILL BE LACKLUSTER,
LIKELY PREVENTING ANY PRECIP FROM REACHING THE SURFACE EVEN IF
WE DID MANAGE SOME RADAR RETURNS OVER THE CWA.
INTO THE DAY TUESDAY EXPECT BUILDING LOW PRESSURE TO THE WEST TO
GRADUALLY INCREASE WINDS AS THE LOW IMPINGES ON THE HIGH TO THE
EAST INCREASING THE PRESSURE GRADIENT, BRINGING BREEZY SOUTH
WINDS TO THE AREA THROUGH THE DAY. THE FRONT WILL TRACK THROUGH
OVERNIGHT INTO WEDNESDAY WITH NO PRECIP EXPECTED GIVEN VERY DRY
COLUMN IN LARGE PART ACROSS SOUTHERN WI, THOUGH WE MAY MANAGE TO
TO BUILD A LITTLE CLOUD COVER WITH THE FRONTAL PASSAGE.
WEDNESDAY INTO WEDNESDAY NIGHT THE SURFACE LOW PRESSURE WILL
GRADUALLY PUSH OUT ALLOWING FOR HIGHER PRESSURE TO BEGIN
BUILDING INTO THE REGION FRONT THE WEST, PARTICULARLY
OVERNIGHT.

LONG TERM
ISSUED 1110 PM CDT MON OCT 5 2026
THURSDAY THROUGH SUNDAY:
ENSEMBLES GENERALLY SUGGEST THE QUIETER WEATHER PATTERN WILL
CONTINUE WITH HIGH PRESSURE BUILDING BACK INTO THE REGION
THURSDAY INTO FRIDAY. ALOFT, THINGS BECOME A BIT MORE ACTIVE
WITH SOME SHORTWAVE ACTIVITY SWINGING NEAR THE CWA LATE IN THE
WEEK BUT THE ISSUE IS THAT THERE REMAINS TOO MUCH DRY AIR TO
CAUSE MUCH OF ANY PRECIP CHANCES. MODELS SUGGEST A MILD CHANCE FOR
PRECIP WITH THE SHORTWAVE BUT WILL RELY LARGELY ON LOW TO
MIDLEVEL MOISTURE AND WAA, WHICH REMAINS UNCERTAIN. THE PATTERN
WILL SWITCH UP INTO THE WEEKEND LARGE SCALE RIDGING BUILDING
OVERHEAD BEHIND A TROUGH SWEEPING THROUGH FRIDAY WHILE THE
REMNANTS OF A TROPICAL CYCLONE MAY SWING UP FROM THE SOUTH.
MODELS GENERALLY SHOW LIMITED POTENTIAL FOR IT TO MAKE IT HERE
BUT THIS COULD AT LEAST INTRODUCE SOME INCREASED MOISTURE IN
PARTS OF THE ATMOSPHERE LATER SUNDAY. OVERALL THE PATTERN IS
SUGGESTIVE OF LARGELY DRY CONDITIONS UNTIL AT LEAST EARLY NEXT
WEEK.

EXPECTED TO BE A DRY COLD FRONT WITH NO RAIN BUT A WIND SHIFT TO
NORTHWEST BY WEDNESDAY MORNING. NORTHWEST WINDS WILL EVENTUALLY
