AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
130 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.
FORECAST UPDATE
ISSUED AT 951 PM EDT THU MAY 28 2026
LITTLE TO NO CHANGES MADE FOR THIS EVENING'S UPDATE AS HIGH PRESSURE
WILL BE THE DOMINANT WEATHER INFLUENCE OVER INDIANA FOR THE
FORESEEABLE FUTURE. FOR TONIGHT, THE HIGH IS CENTERED JUST TO THE
NORTHEAST OVER MICHIGAN, KEEPING LIGHT NORTHEASTERLY WINDS ACROSS
THE STATE. ACARS SOUNDINGS SHOW A VERY DRY ENVIRONMENT THROUGH THE
ENTIRE COLUMN WITH THE EXCEPTION OF SOME HIGH CLOUDS ABOVE 20 KFT
AGL. THE MUCH DRIER AIRMASS ASSOCIATED WITH THE HIGH HAS ENGULFED
THE REGION TODAY AS DEW POINT DEPRESSIONS ARE 20-25 DEGREES FOR THE
NORTHERN 2/3RD OF CENTRAL INDIANA. LINGERING LOW LEVEL MOISTURE FROM
TERRE HAUTE TO BLOOMINGTON AND POINTS SOUTH AND WEST MAY BE ENOUGH
FOR SOME FOG DEVELOPMENT TONIGHT. A GOOD SET UP FOR RADIATIONAL
COOLING WITHIN THE WABASH RIVER VALLEY MAY ALLOW FOR PATCHY FOG
DURING THE OVERNIGHT AND EARLY MORNING HOURS. FOG IS NOT EXPECTED TO
BE AS DENSE OR WIDESPREAD AS LAST NIGHT, BUT THE THREAT FOR
OCCURRENCE IS NON-ZERO. ELSEWHERE ACROSS CENTRAL INDIANA, EXPECT A
QUIET EVENING WITH NO WEATHER IMPACTS.
DISCUSSION (THIS EVENING THROUGH THURSDAY)
ISSUED AT 251 PM EDT THU MAY 28 2026
ENSEMBLE GUIDANCE IS IN GOOD AGREEMENT DEPICTING A JET PATTERN WHICH
WILL LIMIT SIGNIFICANT WEATHER THROUGH THE FORECAST PERIOD. A STRONG
RIDGE IS TAKING SHAPE OVER THE PLAINS AND IS MODELED TO EVOLVE INTO
AN OMEGA BLOCK. SUCH A PATTERN FORCES STORM SYSTEMS TO MOVE UP AND
OVER, WHICH WOULD SEND THE ACTIVE STORM TRACK INTO CANADA. INDIANA
WOULD BE LOCATED WITHIN THE EASTERN EDGE OF THE LARGER UPPER-LEVEL
RIDGE. AT THE SURFACE, PERSISTENT HIGH PRESSURE OVER THE GREAT LAKES
WILL ENHANCE THE SUBSIDENT NATURE OF THE ATMOSPHERE.
AS SUCH, GENERALLY DRY AND QUIET WEATHER IS ANTICIPATED THROUGH THE
WEEKEND AND INTO NEXT WEEK. DESPITE STRONG RIDGING JUST TO OUR WEST,
THE POSITION OF THE SURFACE HIGH SHOULD LEAD TO AN EAST TO EAST-
NORTHEASTERLY WIND. THIS SHOULD KEEP TEMPERATURES FROM GETTING TOO
FAR ABOVE NORMAL, WITH HIGHS IN THE UPPER 70S TO NEAR 80 EACH DAY
THROUGH THE MIDDLE OF NEXT WEEK. LOWS LOOK TO BE NEAR NORMAL AS
WELL, WITH READING GENERALLY IN THE MID TO UPPER 50S EACH NIGHT.
NIGHTLY FOG MAY BE POSSIBLE NEAR RIVERS AND IN TYPICAL FOG-PRONE
AREAS.
SOME RAIN SHOWERS MAY GET VERY CLOSE TO THE SOUTHWESTERN PORTION OF
OUR CWA LATE FRIDAY INTO SATURDAY. THESE SHOWERS APPEAR TO ORIGINATE
FROM BROAD SURFACE TROUGHING EXTENDING SOUTHEASTWARD FROM A LEE
CYCLONE ALONG THE FRONT RANGE OF THE ROCKIES. GUIDANCE DOES NOT
INDICATE MUCH EASTWARD PROGRESSION OF THIS AREA OF FORCING, OWING TO
THE STRONG HIGH PRESSURE OF THE GREAT LAKES. WE WILL KEEP
PRECIPITATION CHANCES OUT OF THE FORECAST FOR NOW.
AVIATION (06Z TAF ISSUANCE)
ISSUED AT 130 AM EDT FRI MAY 29 2026
IMPACTS:
- 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.
