QUIET CONDITIONS TONIGHT ACROSS CENTRAL INDIANA WITH CLEAR SKIES AND
TEMPERATURES REMAINING STEADY IN THE MID TO UPPER 30S THROUGH THE

MAIN FOCUS TONIGHT WILL ACTUALLY BE THE CLEAR SKIES OVERHEAD.
SATELLITE IMAGERY SHOWS CLOUDS FINALLY PUSHING OFF TO THE EAST THIS
EVENING AS THE FORECAST CALLS FOR MAINLY CLEAR SKIES OVER THE NEXT
24 HOURS. OPTIMAL CONDITIONS ARE SETTING UP FOR NORTHERN LIGHTS
VIEWING TONIGHT FOR ALL OF CENTRAL INDIANA. THE SPACE WEATHER
PREDICTION CENTER HAS CONFIRMED THAT A G4 SOLAR STORM IS ONGOING
RIGHT NOW RESULTING IN THE AURORA BOREALIS VISIBLE FOR A GOOD
MAJORITY OF THE CONUS. VISIT SWPC.NOAA.GOV FOR MORE INFORMATION ON
THE SOLAR STORM AND AURORA FORECAST.

SHORT TERM (THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 221 PM EST TUE NOV 11 2025
CURRENT SATELLITE AND SURFACE OBSERVATIONS DEPICT EXTENSIVE CLOUD
COVER ACROSS THE REGION. THESE CLOUDS ARE ASSOCIATED WITH MOISTURE
STREAMING IN ALOFT AND WEAK FORCING FROM AN UPPER WAVE MOVING
THROUGH. LOW-LEVEL DRY AIR HAS LIMITED ANY POTENTIAL FOR
PRECIPITATION TODAY AND THIS WILL LIKELY CONTINUE WITH FORECAST
SOUNDINGS SHOWING DRY AIR REMAINING NEAR THE SURFACE. WIDESPREAD MID-
HIGH CLOUDS ARE HELPING TO REDUCE DIURNAL HEATING, BUT TEMPERATURES
HAVE GRADUALLY WARMED UP THANKS TO STRONG SOUTHWESTERLY FLOW. THE
STRONG MSLP GRADIENT ACROSS CENTRAL INDIANA AND DAYTIME MIXING INTO
A STRONG LLJ OVERHEAD IS PROMOTING STRONG WIND GUSTS BETWEEN 25-35
MPH.
PBL STABILIZATION THIS EVENING INTO TONIGHT SHOULD ALLOW FOR GUSTS
TO DIMINISH EVENTUALLY. GUSTS MAY NOT COMPLETELY DIMINISH UNTIL LATE
TONIGHT THOUGH AS BREEZY CONDITIONS WILL SLOW THE PBL DECOUPLING
PROCESS. FORECAST SOUNDINGS SHOW INCREASING SUBSIDENCE TONIGHT INTO
WEDNESDAY AND A DRY COLUMN SUPPORTING QUIET WEATHER. MODEL GUIDANCE
ALSO DEPICTS INCREASING HEIGHTS ALOFT WEDNESDAY ONCE UPPER RIDGING
BEGINS TO DEPART AND RIDGING CENTERED NEAR THE ROCKIES SHIFTS EAST.
THIS ALONG WITH MOSTLY CLEAR SKIES WILL ALLOW TEMPERATURES TO WARM
INTO THE 50S FOR MOST OF THE AREA. EXPECT WIND GUSTS AROUND 20-30
MPH TO RETURN DURING THE DAY WEDNESDAY ONCE NEAR SURFACE LAPSE RATES
STEEPEN.
LONG TERM (WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 221 PM EST TUE NOV 11 2025
WEDNESDAY NIGHT THROUGH SATURDAY...
MOSTLY QUIET WEATHER IS EXPECTED THROUGH THE FIRST HALF OF THE
EXTENDED AS UPPER RIDGING SHIFTS EASTWARD TOWARDS THE REGION LATE
WEEK. INCREASING WARM AIR ADVECTION AND DEEPER MOISTURE RETURNING
NORTH MAY SUPPORT ISOLATED SHOWERS AT TIMES. WEAK FORCING SHOULD
KEEP ANY RAINFALL AMOUNTS VERY LIGHT THOUGH. A SIGNIFICANT WARMING
TREND WILL BE THE PRIMARY FOCUS WITH TEMPERATURES EXPECTED TO REACH
THE LOW-MID 60S FRIDAY AND POSSIBLY LOW 70S OVER PORTIONS OF CENTRAL
INDIANA BY SATURDAY. HIGHS ARE NORMALLY IN THE MID 50S THIS TIME OF
YEAR.
SATURDAY NIGHT THROUGH TUESDAY...
RAIN CHANCES BECOME MORE WIDESPREAD, BUT REMAIN LOW LATE WEEKEND AS
GUIDANCE SHOWS AN UPPER TROUGH AND LOW PRESSURE SYSTEM PUSHING
THROUGH THE REGION. WARM AIR ADVECTION AHEAD OF AN ASSOCIATED COLD
FRONT WILL KEEP TEMPERATURES ABOVE NORMAL. SLIGHTLY DEEPER MOISTURE
IS ALSO EXPECTED TO ADVECT NORTHWARD. THIS ALONG WITH FORCING FROM
THE SYSTEM SUPPORTS LOW PRECIPITATION CHANCES ACROSS THE ENTIRE
FORECAST AREA ON SUNDAY. COLD AIR ADVECTION BEHIND THE DEPARTING
FRONT SHOULD TREND TEMPERATURES COOLER LATE SUNDAY INTO MONDAY.
PRECIPITATION CHANCES REMAIN ELEVATED EARLY NEXT WEEK AS GUIDANCE
DEPICTS ANOTHER SYSTEM QUICKLY MOVING IN. DIVERGING MODEL SOLUTIONS
LEADS TO GREATER UNCERTAINTY REGARDING EXACT DETAILS. IT DOES
APPEAR THIS SYSTEM MAY PROVIDE A BETTER CHANCE FOR RAINFALL THOUGH
AS DEEPER MOISTURE STREAMS NORTHWARD WITHIN PERSISTENT SW LOW-LEVEL
FLOW. NEAR SEASONAL TEMPERATURES ARE GENERALLY EXPECTED EARLY NEXT
WEEK.
