AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
649 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
