UPDATE
THE AVIATION SECTION HAS BEEN UPDATED BELOW.
SYNOPSIS
ISSUED AT 343 AM EDT TUE MAR 26 2019
HIGH PRESSURE WILL BRING QUIET CONDITIONS TO CENTRAL INDIANA FOR
THE NEXT COUPLE OF DAYS. AFTER THAT A MORE ACTIVE PATTERN WILL
ARRIVE WITH CHANCES FOR RAIN ON AND OFF STARTING WEDNESDAY NIGHT
IN THE NORTH AND OVER THE ENTIRE AREA FROM THURSDAY NIGHT THROUGH
SATURDAY NIGHT. ABOVE NORMAL TEMPERATURES ARE EXPECTED THURSDAY
THROUGH FRIDAY, BUT THE REST OF THE FORECAST PERIOD WILL BE NEAR
TO BELOW NORMAL.
NEAR TERM /TODAY/
ISSUED AT 343 AM EDT TUE MAR 26 2019
HIGH PRESSURE WILL BUILD OVER CENTRAL INDIANA TODAY FROM THE
NORTH. THIS WILL KEEP SKIES CLEAR AND SUNNY. NORTHERLY COMPONENT
FLOW THOUGH WILL KEEP HIGH TEMPERATURES BELOW NORMAL FOR ANOTHER
DAY. LOOK FOR HIGHS IN THE MIDDLE 40S NORTHEAST TO LOWER 50S
SOUTHWEST.
SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/
ISSUED AT 343 AM EDT TUE MAR 26 2019
HIGH PRESSURE WILL KEEP DRY CONDITIONS OVER CENTRAL INDIANA
THROUGH WEDNESDAY. LOW TEMPERATURES TONIGHT WILL DIP BELOW
FREEZING INTO THE MID 20S TO AROUND 30 UNDER MOSTLY CLEAR SKIES,
BUT THE EXTRA SUNSHINE FROM CONTINUED MOSTLY SUNNY SKIES WILL
BRING TEMPERATURES BACK TO NEAR NORMAL FOR WEDNESDAY.
AS AN UPPER RIDGE ALOFT GETS FLATTENED AND SLOWLY MOVES OFF TO THE
EAST, CHANCES FOR RAIN WILL RETURN TO CENTRAL INDIANA, FIRST
ACROSS THE NORTHERN COUNTIES CLOSEST TO THE WEAK UPPER DISTURBANCE
MOVING THROUGH THE TOP OF THE FLATTENED RIDGE. THUS SHOULD SEE LOW
CHANCES FOR RAIN ACROSS THE NORTHERN COUNTIES WEDNESDAY NIGHT
THROUGH THE DAY ON THURSDAY. WITH THE UPPER RIDGE AXIS MOVING OFF
TO THE EAST, SOUTHWESTERLY FLOW WILL BRING IN WARMER TEMPERATURES
FOR THURSDAY. BY THURSDAY NIGHT, STRONGER FORCING WILL ARRIVE IN
THE FORM OF A STALLING SURFACE FRONT AND AN UPPER WAVE AND THIS
WILL OVERSPREAD RAIN ACROSS THE AREA.
LONG TERM /FRIDAY THROUGH MONDAY NIGHT/
ISSUED AT 345 AM EDT TUE MAR 26 2019
DISTURBANCES INTERACTING WITH A FRONTAL BOUNDARY WILL BE THE FOCUS
OF SHOWER AND THUNDERSTORM ACTIVITY EARLY IN THE EXTENDED PERIOD.
RAIN SHOWERS WILL MEANDER AROUND THIS FRONTAL BOUNDARY FOR MOST
OF FRIDAY, AND THEN A SURFACE LOW WILL QUICKLY MOVE IN FROM THE
SOUTHERN PLAINS BY FRIDAY NIGHT. THIS LOW WILL PROVIDE ENOUGH LIFT
TO PRODUCE SOME THUNDERSTORMS FRIDAY NIGHT AND SATURDAY.
THUNDERSTORM CHANCES SHOULD SUBSIDE BY SATURDAY EVENING THOUGH
WITH JUST SOME LINGERING RAIN SHOWERS (EAST) AS THE AFOREMENTIONED
LOW MOVES EASTWARD. AT THAT POINT, HIGH PRESSURE WILL BUILD INTO
THE REGION, AND DRY CONDITIONS WILL PREVAIL THROUGH MONDAY. THE
NEXT CHANCE FOR PRECIPITATION AFTER THAT WILL BE MONDAY NIGHT, AND
BELOW NORMAL TEMPERATURES COULD RESULT IN SOME SNOW SHOWERS MIXED
IN WITH THE RAIN.
