AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
628 PM EST TUE FEB 3 2026
KEY MESSAGES
- WINTER WEATHER ADVISORY REMAINS IN EFFECT FROM 7AM TO 7PM TODAY
ACROSS FAR SE COUNTIES, GREATEST CHANCE FOR IMPACTS DURING THE
AFTERNOON.
- CHANCES FOR ABOVE FREEZING HIGHS LATE THIS WEEK AND AGAIN MID-
NEXT WEEK
SHORT TERM (THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 305 PM EST TUE FEB 3 2026
WEAK SURFACE CYCLOGENESIS HAS LED TO DEEPENING LOW PRESSURE OVER
THE SOUTHERN OHIO VALLEY THROUGHOUT TODAY, OF WHICH IS CREATING A
NARROW CORRIDOR OF FRONTOGENESIS WITHIN SOUTHERN INDIANA. IN
RETURN, BANDED SNOWFALL HAS FORMED OVER THIS REGION, WITH MODERATE
SNOW RATES BEING OBSERVED. FURTHER ANALYSIS ON THE SPECIFICS OF
THIS BANDED SNOWFALL IS IN THE MESOSCALE SECTION AT THE TOP OF THE
AFD.
THESE SNOWBANDS ARE EXPECTED TO CONTINUE THROUGHOUT THE AFTERNOON
AND EVENING, BUT WILL LIKELY BE SOUTH OF THE CENTRAL INDIANA CWA
WITHIN THE NEXT 3 HOURS. STILL, A QUICK 1-2 INCHES IS POSSIBLE IN
PLACES LIKE SEYMOUR AND NORTH VERNON BEFORE THE SNOW ENDS. THE
WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL 7PM, BUT THIS WILL
LIKELY BE ENDED EARLY ONCE THE SNOW EXIT TO THE SE.
OVERNIGHT, COLD AIR ADVECTION WILL PUSH IN COOLER TEMPERATURES BUT A
CONSISTENT BROKEN TO OVERCAST STRATUS DECK WILL LIKELY LIMIT DIURNAL
COOLING SOME WITH LOWS IN THE TEENS TO NEAR 10 DEGREES TOMORROW
MORNING. TOMORROW WILL HAVE RELATIVELY QUIET BUT COLD WEATHER AS THE
BULK OF THE COOLER AIRMASS ARRIVES BENEATH MID-LEVEL PRESSURE GAINS.
THIS SHOULD RESULT IN SOME CLEARING, BUT THERE WILL LIKELY STILL BE
SOME MID TO UPPER LEVEL CLOUD COVER WITHIN A STRONG JET STREAM.
LONG TERM (WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 305 PM EST TUE FEB 3 2026
AN UPPER TROUGH WILL BE MAKING ITS WAY EASTWARD FOR THE END OF THE
WEEK BEFORE MORE ZONAL UPPER FLOW MOVES OVER CENTRAL INDIANA. THIS
WEEKEND INTO NEXT WEEK MAY SEE SOME RIDGING AT TIMES BUT MODELS LACK
CLEAR AGREEMENT PAST THIS WEEKEND. GENERALLY TEMPERATURES WILL TREND
WARMER THAN WE HAVE SEEN IN SEVERAL WEEKS. HIGHS ON FRIDAY ARE
EXPECTED TO BE IN THE MID 30S TO LOW 40S BUT A QUICK MOVING SYSTEM
WILL DROP HIGHS BACK TO THE 20S ON SATURDAY BEFORE ANOTHER WARMING
TREND RETURNS FROM SUNDAY AND ON.
DRY WEATHER IS EXPECTED FOR MUCH OF THE LONG TERM PERIOD DUE
PARTIALLY TO LIMITED MOISTURE AVAILABILITY BUT A FEW PASSING WAVES
WOULD MAKE LIGHT PRECIPITATION POSSIBLE AT TIMES. THE FAR NORTH
COULD SEE SOME SNOW SHOWERS EARLY FRIDAY WITH THE PASSAGE OF A
FRONTAL SYSTEM. THE NEXT BEST CHANCE OF PRECIP WILL COME AT THE END
OF THE PERIOD WITH THE POTENTIAL FOR AN APPROACHING TROUGH AND
SURFACE LOW.
AVIATION (00Z TAF ISSUANCE)
ISSUED AT 628 PM EST TUE FEB 3 2026
IMPACTS:
- MVFR CEILINGS DEVELOPING ACROSS ALL TERMINALS TONIGHT LASTING
THROUGH MUCH OF TOMORROW
DISCUSSION:
IN THE WAKE OF THE WEAK STORM SYSTEM THAT MOVED OVER THE AREA IN THE
LAST 12 HOURS, SKIES HAVE BRIEFLY CLEARED FOR ALL BUT KBMG. HOWEVER,
PREVAILING N-NE FLOW WILL SUPPORT REDEVELOPMENT OF CLOUDS,
SPECIFICALLY MVFR CEILINGS, INTO THE TERMINALS OVERNIGHT. SOME DRY
AIR MAY HELP TO SCATTER OUT THE CLOUDS FOR A TIME TOMORROW AT KLAF
AND KIND, BUT OVERALL PERSISTENCE IN THE LOW CLOUDS WILL BE THE
RULE. A FEW FLURRIES MAY DEVELOP TOMORROW AFTERNOON WITH SOME MINOR
INSTABILITY AND AN APPROACHING WEAK UPPER LEVEL STORM SYSTEM.
HOWEVER, DURATION OF FLURRIES SHOULD BE TOO LIMITED TO WARRANT
MENTION IN THE TAFS. WINDS WILL BE N-NE 5-10 KTS THROUGH THE PERIOD.
IND WATCHES/WARNINGS/ADVISORIES
NONE.
