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.
