NATIONAL WEATHER SERVICE INDIANAPOLIS IN
321 PM EDT WED MAR 18 2026
KEY MESSAGES
- LOW RAIN CHANCES LATE TONIGHT INTO EARLY THURSDAY MORNING NORTHEAST
- ABOVE NORMAL TEMPERATURES RETURN LATE WEEK INTO THE WEEKEND
SHORT TERM (THIS EVENING THROUGH THURSDAY)
ISSUED AT 321 PM EDT WED MAR 18 2026
A FAIRLY QUIET EVENING IS IN THE OFFING FOR CENTRAL INDIANA AS HIGH
PRESSURE NUDGES INTO THE AREA. THE LOW CLOUDS ARE STEADILY
ERODING/PUSHING EASTWARD, WHICH WILL ALLOW FOR A RELATIVELY CLEAR
EVENING ACROSS THE AREA, BEFORE ADDITIONAL HIGH CLOUD AND THEN MID
CLOUD MOVES IN LATE WITH A WEAK UPPER LEVEL DISTURBANCE.
MID AND UPPER LEVELS WILL MOISTEN UP ASSOCIATED WITH THIS, HENCE THE
INCREASED CLOUD COVER LATE TONIGHT INTO EARLY TOMORROW, BUT THE LOW
LEVELS REMAIN SUBSTANTIALLY DRY. WILL CARRY SOME LOW POPS IN THE
NORTHEAST LATE TONIGHT INTO THURSDAY MORNING, BUT AMOUNTS, IF ANY
MEASURABLE, WILL BE QUITE MINIMAL.
SKIES SHOULD CLEAR RELATIVELY QUICKLY BY THE AFTERNOON, WHICH ALONG
WITH INCREASED LOW LEVEL THICKNESSES WILL ALLOW TEMPERATURES TO
RECOVER FROM MORNING LOWS IN THE 30S TO AROUND 40 TO AFTERNOON HIGHS
IN THE UPPER 50S TO MID TO UPPER 60S ACROSS THE AREA.
LONG TERM (THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 321 PM EDT WED MAR 18 2026
THOUGH THE PATTERN WILL LARGELY REMAIN CHARACTERIZED BY A
SUBSTANTIAL WESTERN/SOUTHWESTERN CONUS RIDGE AND NORTHWEST OR AT
LEAST WNW FLOW ALOFT, SUBSTANTIALLY WARMER CONDITIONS ARE EXPECTED,
PARTICULARLY DURING THE FIRST HALF OF THE LONG TERM PERIOD OR
THROUGH THE COMING WEEKEND, AS THE RIDGE FLATTENS A BIT AND NUDGES
EASTWARD, AND SIGNIFICANT LOW LEVEL WARM ADVECTION OCCURS.
TEMPERATURES SHOULD NEAR OR EXCEED THE 70 DEGREE MARK EACH DAY
FRIDAY THROUGH SATURDAY, WITH 80 DEGREE READINGS NOT ENTIRELY OUT OF
THE QUESTION SOUTH LATE IN THE WEEKEND.
THIS WILL BE ACCOMPANIED BY DRY CONDITIONS FOR THE MOST PART, SAVE
FOR A LOW CHANCE FOR SHOWERS SUNDAY INTO SUNDAY NIGHT AS A FRONT
SINKS THROUGH THE AREA AND BRINGS TEMPS BACK DOWN TO NEARER NORMAL
AT LEAST BRIEFLY EARLY NEXT WEEK. HIGH PRESSURE OVER THE GULF WILL
LIMIT MOISTURE AVAILABILITY, THUS THE LOWER POPS.
THE COOLDOWN SHOULD BE RELATIVELY BRIEF, AS THE WESTERN RIDGE
RESTRENGTHENS AND NUDGES EVEN A BIT FURTHER EASTWARD TOWARD THE END
OF THE PERIOD NEXT WEEK.

MORNING.
