DISCUSSION (THIS EVENING THROUGH SATURDAY)
ISSUED AT 210 PM EDT SAT SEP 26 2026
REST OF THIS AFTERNOON THROUGH TONIGHT...
QUIET WEATHER WILL CONTINUE THROUGH THIS EVENING WITH JUST SOME HIGH
CLOUDS AT TIMES ACROSS PORTIONS OF THE AREA.
TONIGHT, THERE WILL BE SOME HIGH CLOUDS FROM THE WEST AGAIN. WINDS
WILL DIMINISH. WITH THESE CONDITIONS, EXPECT PATCHY FOG TO FORM ONCE
AGAIN. SHORT TERM GUIDANCE FOCUSES THE FOG ON THE NORTHEAST FORECAST
AREA AGAIN, BUT FEEL THAT, IF THE CIRRUS IS THIN ENOUGH WEST, PATCHY
FOG WILL BE ABLE TO FORM FARTHER WEST.
WITH THE EXPECTED CONDITIONS, NUDGED GUIDANCE'S LOW TEMPERATURES
DOWN A BIT IN SOME AREAS. LOWS WILL BE MAINLY IN THE 40S.
SUNDAY THROUGH TUESDAY...
SUBSIDENCE TO THE WEST OF A LARGE UPPER LOW ACROSS THE EASTERN USA
EARLY FOLLOWED BY SOME UPPER RIDGING MOVING IN WILL KEEP THE WEATHER
QUIET ACROSS CENTRAL INDIANA DURING THIS PERIOD. AT THE SURFACE,
HIGH PRESSURE WILL REMAIN IN CONTROL.
SOME HIGH AND MID CLOUDS WILL CONTINUE ACROSS THE WESTERN
FORECAST AREA. SUNDAY NIGHT AND MONDAY NIGHT, SOME PATCHY FOG WILL
LIKELY DEVELOP ONCE AGAIN WITH SIMILAR CONDITIONS TO TONIGHT.
TEMPERATURES WILL GRADUALLY WARM TO ABOVE NORMAL AS THE AIRMASS
MODERATES AND WINDS BECOME SOUTHERLY.
WEDNESDAY ONWARD...
A SLOW MOVING WEAKENING UPPER SYSTEM WILL MOVE NORTHEAST INTO THE
CENTRAL USA BY FRIDAY. AT THE SURFACE, AN ASSOCIATED MEANDERING
SURFACE FRONT WILL LINGER ACROSS THE AREA.
THE RESULT WILL BE RAIN CHANCES ACROSS CENTRAL INDIANA. QUESTIONS
REMAIN THOUGH ON THE SPEED OF THE SYSTEM AND HOW MUCH FORCING WILL
BE ACROSS CENTRAL INDIANA DURING ANY ONE PERIOD. THUS CONFIDENCE IS
LOW ON THE SPECIFICS OF THE POPS AND WHEN THE HIGHEST CHANCES OF
RAIN WILL BE. THE UPPER SYSTEM WILL HAVE INGESTED TROPICAL MOISTURE,
SO DEPENDING ON WHERE THE SURFACE FRONT SETS UP, LOCALLY HEAVY RAIN
MAY BE POSSIBLE FOR PARTS OF THE AREA BY FRIDAY.
FOR NEXT WEEKEND, GUIDANCE DIFFERS ON THE NEXT LARGER UPPER TROUGH,
KEEPING UNCERTAINTY HIGH. WILL CONTINUE WITH SOME POPS INTO SATURDAY.
ABOVE NORMAL TEMPERATURES LOOK TO CONTINUE INTO THURSDAY, BUT
READINGS A LITTLE BELOW NORMAL COULD RETURN FRIDAY INTO SATURDAY
DEPENDING ON RAIN COVERAGE/SKY COVER/WHERE THE FRONT ENDS UP.
