FORECAST UPDATE
ISSUED AT 933 AM EDT SAT APR 11 2026
AN AREA OF CLOUDS CONTINUES TO PERSIST ACROSS PORTIONS OF SOUTHERN
CENTRAL INDIANA THIS MORNING. SOME OF THE CLOUDS NEAR INDY HAVE
MIXED OUT, BUT THICKER CLOUDS REMAIN TO THE SOUTH. THESE WILL MIX
OUT THIS MORNING AS HEATING CONTINUES. ADJUSTED SKY COVER UP THIS
MORNING AS NEEDED.
OTHERWISE, MAINLY HIGH CLOUDS WILL INCREASE TODAY, ALLOWING SKIES TO
AVERAGE PARTLY CLOUDY OVERALL FOR MOST AREAS. FORECAST HIGH
TEMPERATURES LOOK REASONABLE GIVEN EXPECTED CONDITIONS, SO MADE NO
CHANGES AT THIS TIME.
DISCUSSION (TODAY THROUGH FRIDAY)
ISSUED AT 246 AM EDT SAT APR 11 2026
STRATUS HAS SHIFTED INTO THE SOUTHERN PART OF THE FORECAST AREA AS
DRIER AIR ADVECTS INTO THE REGION FROM THE GREAT LAKES. TEMPERATURES
HAD FALLEN INTO THE 40S OVER MOST OF CENTRAL INDIANA AT 06Z WITH
EVEN A FEW LOCATIONS IN THE UPPER 30S OVER FAR NORTHERN COUNTIES.
HIGH PRESSURE WILL DRIFT ACROSS THE GREAT LAKES TODAY AS THE COLD
FRONT THAT PASSED THROUGH THE AREA ON FRIDAY SETTLES ACROSS THE
TENNESSEE VALLEY. THE FRONT WILL LIFT BACK NORTH AS A WARM FRONT
EARLY SUNDAY. THE BOUNDARY WILL THEN BECOME QUASI-STATIONARY TO THE
NORTH OF THE AREA INTO THE FIRST HALF NEXT WEEK WITH PERIODIC
CHANCES FOR CONVECTION AS A WARM AND INCREASINGLY HUMID AIRMASS SETS
UP OVER THE OHIO VALLEY.
TODAY THROUGH SUNDAY
AN INITIAL ISSUE EARLY THIS MORNING IS THE POTENTIAL FOR PATCHY
FROST TO DEVELOP OVER FAR NORTHERN PORTIONS OF THE FORECAST AREA AS
TEMPERATURES DROP INTO THE MID 30S IN A FEW LOCATIONS. WINDS HAVE
FALLEN TO CLOSER TO 5 MPH WHICH WILL LIKELY ALLOW FOR ISOLATED FROST
ACCRUAL FOCUSED ACROSS THE NORTHERN WABASH VALLEY EAST TOWARDS
KOKOMO IN THE PREDAWN HOURS.
HIGH PRESSURE WILL SERVE AS THE PRIMARY FEATURE INFLUENCING THE
WEATHER ACROSS THE AREA INTO SUNDAY AS IT TRACKS EAST ACROSS THE
GREAT LAKES TODAY INTO NEW ENGLAND BY SUNDAY. DEEPER SUBSIDENCE WILL
KEEP SKIES MOSTLY CLEAR INTO THIS AFTERNOON WITH ONLY PASSING CIRRUS
PERIODICALLY. LOW LEVEL FLOW WILL VEER TO EASTERLY TODAY THEN
SOUTHEAST BY THIS EVENING AS THE HIGH MOVES AWAY TO THE EAST AND THE
BOUNDARY BEGINS ITS TREK NORTH AS A WARM FRONT. TEMPERATURES WILL BE
MILD THIS AFTERNOON AFTER THE CHILLY START...WITH HIGHS RANGING FROM
THE MID 60S NORTH TO THE LOWER 70S SOUTH. INCREASING MOISTURE ALOFT
POOLING ALONG THE FRONT WILL PROMPT AN INCREASE IN CLOUDS TONIGHT AS
THE FRONT LIFTS THROUGH THE REGION.
CLOUDS WILL THIN AGAIN EARLY SUNDAY AS THE FRONT MOVES NORTH INTO
THE LOWER GREAT LAKES WITH STRONG SOUTHWESTERLY WINDS DEVELOPING AS
WARM ADVECTION STRENGTHENS AND THE SURFACE PRESSURE GRADIENT
TIGHTENS ACROSS THE OHIO VALLEY. PEAK GUSTS SUNDAY AFTERNOON AT 30
TO 35MPH ARE POSSIBLE ACROSS THE NORTHERN HALF OF THE FORECAST AREA.
EVEN WITH CLOUDS INCREASING AGAIN IN THE AFTERNOON TEMPERATURES WILL
RISE INTO THE LOWER 80S ACROSS THE REGION.
SUNDAY NIGHT THROUGH FRIDAY
AN AMPLIFIED UPPER LEVEL REGIME HIGHLIGHTED BY A WESTERN TROUGH AND
AN EASTERN RIDGE WILL SUPPORT A TRANSITION TO A MORE ACTIVE AS
MULTIPLE PIECES OF ENERGY EJECT OUT FROM THE TROUGH AND ACROSS THE
CENTRAL PART OF THE COUNTRY. THE INITIAL WAVE WILL SWING THROUGH THE
REGION SUNDAY NIGHT SPREADING SHOWERS AND A FEW RUMBLES OF THUNDER
ACROSS THE FORECAST AREA THROUGH MONDAY MORNING. SCATTERED
CONVECTION MAY REDEVELOP LATER IN THE DAY ON MONDAY WITH WEAK
RIDGING AT THE SURFACE AND ALOFT BRINGING DRIER AIR BRIEFLY BACK
ACROSS THE REGION MONDAY NIGHT.
A MULTI DAY RISK FOR SEVERE WEATHER REMAINS A FOCUS FOR THE FIRST
HALF OF THE WEEK WITH THE GREATEST THREAT ACROSS CENTRAL INDIANA ON
TUESDAY AND WEDNESDAY AS A STRONGER SURFACE WAVE KICKS OUT ALONG THE
BOUNDARY TO OUR NORTH AND MOVES INTO THE UPPER MIDWEST. GIVEN THE
PROJECTED KINEMATIC PROFILES AND AVAILABLE INSTABILITY...ALL MODES
OF SEVERE WEATHER WOULD BE IN PLAY ACROSS CENTRAL INDIANA DURING
THIS TIMEFRAME. LOCALLY HEAVY RAINFALL WOULD ALSO BE A CONCERN. THE
FRONT WILL DRIFT SOUTH BUT LIKELY LINGER IN THE OHIO VALLEY INTO
NEXT WEEKEND BEFORE FINALLY CLEARING THE REGION. TEMPERATURES WILL
REMAIN WARM NEXT WEEK WITH HIGHS IN THE UPPER 70S AND LOWER 80S EACH
DAY. COOLER WEATHER WILL ARRIVE BY NEXT WEEKEND.

THIS EVENING AND TONIGHT AS THE FRONTAL BOUNDARY RETURNS INTO THE
AREA AS A WARM FRONT.
WINDS WILL VEER FROM NORTHEAST EARLY THIS MORNING TO EASTERLY FOR
MUCH OF THE DAY THEN SOUTHEAST THIS EVENING AND TONIGHT AS THE WARM
