DISCUSSION (THIS EVENING THROUGH SATURDAY)
ISSUED AT 244 PM EDT SAT SEP 19 2026
WIDELY SCATTERED SHOWERS AND STORMS WILL CONTINUE ACROSS PORTIONS OF
CENTRAL INDIANA THIS AFTERNOON, THOUGH MODEST INSTABILITY AND WEAK
SHEAR IS LIMITING COVERAGE AND INTENSITY SIGNIFICANTLY. THIS
ACTIVITY SHOULD LARGELY COME TO AN END THIS EVENING AS HEATING IS
LOST, THOUGH A WEAK UPPER WAVE MAY ALLOW A FEW SHOWERS TO LINGER,
MAINLY NORTH.
A SLIGHTLY MORE SUBSTANTIAL UPPER WAVE ARRIVES SUNDAY, AND WILL
PROMOTE SCATTERED TO POTENTIALLY WIDESPREAD SHOWERS AND STORMS,
PARTICULARLY DURING THE AFTERNOON AND EVENING HOURS. MODEST
INSTABILITY AND DEEP LAYER SHEAR MAY PROMOTE SLIGHTLY BETTER
COVERAGE AND A SLIGHT UPTICK IN INTENSITY TOMORROW, AND POSSIBLY A
SMALL HAIL THREAT IN ADDITION TO THE LOCALIZED STRONG WIND THREAT,
AND THE CONTINUED HEAVY DOWNPOUR THREAT.
THOUGH THE SURFACE FRONT PUSHES FURTHER SOUTH AS WE MOVE INTO THE
WORK WEEK, A SLOW-MOVING UPPER LEVEL LOW WILL PASS THROUGH THE AREA
THROUGH MID WEEK, WITH CHANCES FOR SHOWERS AND PERHAPS A FEW
THUNDERSTORMS LINGERING INTO WEDNESDAY, THOUGH CHANCES SHOULD BE
HIGHEST WHEN DIURNALLY FAVORED/NEAR PEAK HEATING.
HIGH PRESSURE IN THE WAKE OF THE UPPER LOW SHOULD BRING MILD AND
PLEASANT WEATHER TO THE AREA LATE IN THE WEEK.
TEMPERATURES WILL REMAIN WARM THROUGH SUNDAY, THOUGH THE GRADIENT
WILL BE RELATIVELY STRONG WITH THE SURFACE FRONT IN THE AREA. ONCE
THE FRONT IS SHUTTLED SOUTHWARD, TEMPERATURES THROUGH THE REMAINDER
OF THE PERIOD SHOULD BE NEAR TO BELOW NORMAL, WITH HIGHS LARGELY IN
THE 70S AND LOWS LARGELY IN THE 50S FROM MONDAY ONWARD.
AVIATION (00Z TAF ISSUANCE)
ISSUED AT 603 PM EDT SAT SEP 19 2026
IMPACTS:
- MAINLY VFR CONDITIONS ARE EXPECTED THIS TAF PERIOD.
DISCUSSION:
DIURNAL SHOWERS ASSOCIATED WITH A PASSING UPPER WAVE WILL DIMINISH
THIS EVENING LEADING TO VFR CIGS OVERNIGHT.
ANOTHER SHORT WAVE IS EXPECTED TO PASS ON SUNDAY ALONG WITH A
SURFACE COLD FRONT. THIS WILL CONTINUE TO BRING VFR CIGS THROUGH THE
MORNING. HRRR SUGGESTS A FEW SCATTERED LIGHT RAIN SHOWERS POSSIBLE
ACROSS THE NORTHERN HALF OF THE STATE, BUT CONFIDENCE IS LOW. WILL
USE A VCSH MENTION FOR NOW.
BY LATE SUNDAY AFTERNOON THE SURFACE FRONT WILL HAVE PASSED AND
WINDS WILL BECOME NORTHERLY. MODELS SUGGEST COLD AIR ADVECTION MVFR
CU ARRIVING LATE ON SUNDAY AFTERNOON INTO SUNDAY EVENING.
