AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
218 PM EDT SUN SEP 14 2025
KEY MESSAGES
- DRY AND VERY WARM TO HOT CONDITIONS ARE ANTICIPATED FOR MUCH OF
THE WORK WEEK
- DRYING FUELS AND LOWER RH VALUES EACH AFTERNOON MONDAY THROUGH
THURSDAY MAY LEAD TO ELEVATED FIRE THREAT, BUT LIGHT WINDS
SHOULD LIMIT OVERALL CONCERNS
SHORT TERM (THIS EVENING THROUGH MONDAY)
ISSUED AT 217 PM EDT SUN SEP 14 2025
REST OF THIS AFTERNOON...
FEW TO PERHAPS SCATTERED CUMULUS WILL BE AROUND THIS AFTERNOON.
RELATIVELY HUMID CONDITIONS WILL CONTINUE WEST, BUT SOME DRIER AIR
WILL MOVE INTO PORTIONS OF THE EASTERN FORECAST AREA LATER IN THE
AFTERNOON.
THE OLD BOUNDARY WILL CONTINUE TO SLIDE WEST DURING THE DAY, AND ANY
CONVECTION THAT MIGHT POP WITH THAT WILL REMAIN WEST OF THE FORECAST
AREA.
TONIGHT...
ANY CUMULUS WILL DISSIPATE EARLY THIS EVENING, LEAVING BEHIND CLEAR
SKIES. HIGH PRESSURE WILL KEEP THE WEATHER QUIET. ISOLATED FOG IS
POSSIBLE IN RIVER VALLEYS, BUT COVERAGE WON'T BE HIGH ENOUGH TO
MENTION.
LOWS WILL BE IN THE 50S TO LOWER 60S.
MONDAY...
THE UPPER RIDGE AND SURFACE HIGH PRESSURE WILL BE IN CONTROL, AGAIN
KEEPING THE WEATHER QUIET. A FEW CUMULUS MAY POP UP, BUT OTHERWISE
SUNNY SKIES ARE EXPECTED.
HIGHS WILL CONTINUE TO BE ABOVE NORMAL, IN THE MIDDLE 80S TO AROUND
90.
LONG TERM (MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 217 PM EDT SUN SEP 14 2025
A BLOCKING PATTERN WITH AN UPPER LOW ACROSS THE EASTERN USA AND AN
UPPER RIDGE ACROSS CENTRAL INDIANA WILL PERSIST THROUGH MUCH OF THE
WORK WEEK.
THIS WILL RESULT IN VERY WARM TO HOT CONDITIONS ACROSS THE AREA
THROUGH THURSDAY. EVEN WITH A SURFACE TROUGH IN THE VICINITY TO THE
SOUTHEAST, THE UPPER RIDGE SHOULD KEEP A LID ON ANY CONVECTION THAT
WOULD TRY TO DEVELOP.
ALTHOUGH MANY AREAS SAW AT LEAST SOME LIGHT RAIN SATURDAY, THE
EXPECTED CONDITIONS SHOULD STILL DRY THINGS OUT QUICKLY AND KEEP THE
FIRE WEATHER THREAT HIGHER THAN AVERAGE.
THE PATTERN LOOKS TO BECOME MORE PROGRESSIVE FRIDAY INTO NEXT
WEEKEND, WITH AN UPPER LOW MOVING INTO THE AREA. A SURFACE LOW
PRESSURE SYSTEM WILL ACCOMPANY IT. THIS WILL BRING CHANCES FOR RAIN
ALONG WITH GRADUALLY COOLING TEMPERATURES. EVEN WITH HIGHS COOLING
TO AROUND 80 DEGREES, THESE VALUES ARE STILL ABOVE AVERAGE.
AVIATION (18Z TAF ISSUANCE)
ISSUED AT 1244 PM EDT SUN SEP 14 2025

DISCUSSION:
VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD.

RULE OUT SOME BRIEF FOG AT KLAF OVERNIGHT BUT ODDS ARE TOO LOW TO
INCLUDE IN THE TAF. WINDS WILL GENERALLY BE EAST TO SOUTHEAST AT
LESS THAN 10KT.
IND WATCHES/WARNINGS/ADVISORIES
NONE.
