AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
302 AM EDT FRI MAY 29 2026
KEY MESSAGES
- DRY WEATHER EXPECTED TODAY THROUGH THE MIDDLE OF NEXT WEEK.
- NEAR-AVERAGE TEMPERATURES THROUGH THE WEEKEND INTO NEXT WEEK.
DISCUSSION (TODAY THROUGH THURSDAY)
ISSUED AT 300 AM EDT FRI MAY 29 2026
AN OMEGA BLOCK PATTERN IS EXPECTED TO DEVELOP ALOFT INTO THE WEEKEND
WITH RIDGING CENTERED OVER THE CENTRAL CONUS AND CENTRAL PORTIONS OF
CANADA. MEANWHILE, SURFACE HIGH PRESSURE GENERALLY REMAINS IN
CONTROL ACROSS THE GREAT LAKES REGION. THIS WILL LIKELY PROMOTE DRY
WEATHER CONDITIONS THROUGH MOST OR ALL OF THE FORECAST PERIOD. LOOK
FOR INCREASING MID-HIGH CLOUD COVER LATE TODAY INTO SATURDAY AS A
BAND OF MOISTURE ASSOCIATED WITH A DISTURBANCE LIFTS NORTHEASTWARD.
UPPER RIDGING MAY BRIEFLY BREAK DOWN JUST ENOUGH LATE THIS WEEKEND
TO ALLOW A WEAK SHORTWAVE TO MOVE IN FROM THE WEST. CONFIDENCE IS
VERY LOW GIVEN THE OMEGA BLOCK PATTERN IS DIFFICULT TO BREAK DOWN,
BUT IF THE DISTURBANCE DOES NOT DISSIPATE BEFORE REACHING THE REGION
THEN AN ISOLATED SHOWER CANNOT BE COMPLETELY RULED OUT LATE
SUNDAY OR MONDAY.
MODELS ARE BECOMING BETTER ALIGNED INTO EARLY NEXT WEEK DEPICTING
THE OMEGA BLOCK PATTERN REINFORCING ITSELF WHILE THE RIDGE
RETROGRADES SLIGHTLY. GUIDANCE THEN SUGGEST A SHORTWAVE DIVES SOUTH
ACROSS THE EASTERN GREAT LAKES SWEEPING A WEAK COLD FRONT THROUGH
THE AREA. PRECIPITATION IS NOT EXPECTED DUE TO VERY LIMITED MOISTURE
THOUGH THE WEAK FRONT COULD SLIGHTLY COOL TEMPERATURES. SURFACE HIGH
PRESSURE WOULD LIKELY BECOME THE DOMINANT WEATHER FEATURE BEHIND THE
FRONTAL PASSAGE RESULTING IN MORE MUNDANE WEATHER THROUGH THE MIDDLE
OF NEXT WEEK
AVIATION (06Z TAF ISSUANCE)

- NONE.
DISCUSSION:
VFR CONDITIONS EXPECTED.
SURFACE HIGH PRESSURE OVER THE GREAT LAKES WILL KEEP VFR CONDITIONS
AROUND THROUGH THE PERIOD AND GENERALLY LIGHT E/NE WINDS AROUND AND
UNDER 10 KTS. NORTHEASTERLY WINDS WILL BECOME ESE ON FRIDAY.
HIGH CIRRUS FROM THUNDERSTORM ACTIVITY OVER THE GREAT PLAINS WILL BE
PRESENT AT TIMES THROUGH FRIDAY. A DRIER AIRMASS IN PLACE TONIGHT
SHOULD LIMIT THE FOG THREAT COMPARED TO LAST NIGHT; HOWEVER SOME
PATCHY FOG IS NOT OUT OF THE QUESTION IN THE WABASH RIVER VALLEY AND
AROUND KBMG. CONFIDENCE IS TOO LOW TO INCLUDE IN THE TAFS. TAFS WILL
BE UPDATED ACCORDINGLY THIS MORNING IF NEEDED.
IND WATCHES/WARNINGS/ADVISORIES
NONE.
