NATIONAL WEATHER SERVICE INDIANAPOLIS IN
114 PM EDT SUN SEP 6 2026
KEY MESSAGES
- NEARER TO NORMAL TEMPERATURES AND LESS HUMID OVER THE NEXT COUPLE
OF DAYS
- BRIEF RETURN OF HEAT MIDWEEK WITH A CHANCE OF STORMS MID-LATE WEEK
FORECAST UPDATE
ISSUED AT 924 AM EDT SUN SEP 6 2026
NO MAJOR CHANGES NEEDED TO THE FORECAST. SURFACE ANALYSIS THIS
MORNING SHOWS STRONG HIGH PRESSURE STRETCHING ACROSS THE GREAT
LAKES, ONTARIO TO QUEBEC. THIS WAS RESULTING IN A DRY AND COOLER
FLOW OF AIR TO CENTRAL INDIANA. GOES19 SHOWS MAINLY CLEAR SKIES
ACROSS THE AREA AND THE SURFACE TROUGH AND HUMIDITY HAD PUSHED SOUTH
TO ARKANSAS AND TN. WATER VAPOR CONTINUES TO SHOW STRONG RIDGING IN
PLACE OVER THE NORTHERN PLAINS WITH NW FLOW SPILLING SE TO MI AND
INDIANA. WATER VAPOR SHOWS SUBSIDENCE IN PLACE OVER INDIANA. DEW
POINTS ACROSS THE AREA WERE MUCH MORE PLEASANT, IN THE UPPER 50S AND
LOWER 60S.
EXPECT MOSTLY SUNNY SKIES THE REST OF THE DAY AS THE HIGH PRESSURE
SYSTEM TO THE NORTHEAST AND THE PERSISTENT EASTERLY FLOW MAINTAIN
CONTROL OVER OUR WEATHER. FORECAST SOUNDINGS REMAIN DRY THROUGH THE
DAY, WITH A MID LEVEL INVERSION PREVENTING ANY CU. ONGOING HIGHS IN
THE LOWER 80S CONTINUE TO BE ON TARGET.
DISCUSSION (TODAY THROUGH SATURDAY)
ISSUED AT 314 AM EDT SUN SEP 6 2026
COOLER AND DRIER CONDITIONS WILL START OFF THE NEW WEEK BEHIND THE
PASSAGE OF A COLD FRONT AND A CANADIAN AIRMASS AT THE LOWER LEVELS
SAGGING INTO THE GREAT LAKES REGION. HIGHS THE NEXT COUPLE OF DAYS
WILL STAY IN THE 80S WITH LOWS DROPPING INTO THE 60S AND EVEN 50S IN
SOME AREAS.
THIS RETURN TO NEAR NORMAL TEMPERATURES WILL ONLY BE SHORT LIVED AS
UPPER RIDGING RETURNS, BRINGING THE HEAT BACK WITH IT. LUCKILY THIS
TIME THE HEAT WILL BE BRIEF AS THE UPPER PATTERN IS MORE PROGRESSIVE
THAN WAS SEEN LAST WEEK, ALLOWING BROAD UPPER TROUGHING TO ARRIVE
MID TO LATE WEEK. A SHORTWAVE WITH THIS TROUGH WILL BRING WITH IT
ANOTHER SURFACE COLD FRONT AND POTENTIALLY A ROUND OF SHOWERS AND
STORMS. CONFIDENCE IS GROWING IN THIS ROUND OF RAIN MID TO LATE WEEK
AS MODELS START TO HAVE BETTER AGREEMENT ON THE TIMING OF THE WAVE.
TEMPERATURES ARE AGAIN EXPECTED TO DROP BACK TO NEAR NORMAL AGAIN
BEHIND THE WAVE AND LARGELY PERSIST INTO THE WEEKEND. MODELS ARE
HINTING AT ANOTHER POTENTIAL CHANCE OF STORMS LATE NEXT WEEKEND.

DEVELOPMENT.
