FORECAST UPDATE
ISSUED AT 933 AM EDT WED APR 8 2026
THE FORECAST REMAINS IN GOOD SHAPE WITH ONLY MINOR ADJUSTMENTS
NEEDED. THE FREEZE WARNING WAS ALLOWED TO EXPIRE AT 9AM EDT THIS
MORNING AS TEMPERATURES HAVE QUICKLY WARMED INTO THE UPPER 30S TO
LOW 40S.
CURRENT SURFACE ANALYSIS DEPICTS SURFACE HIGH PRESSURE NOW CENTERED
OVER NORTHEAST PORTIONS OF THE CONUS WHILE AN OCCLUDED LOW PRESSURE
SYSTEM NEAR THE CANADIAN/US BORDER BY NORTH DAKOTA CONTINUES TO
SHIFT EASTWARD. LOOK FOR QUIET WEATHER CONDITIONS TO PERSIST TODAY
AS SURFACE RIDGING STILL EXTENDS BACK INTO CENTRAL INDIANA, BUT A
STRENGTHENING MSLP GRADIENT BETWEEN THE AFOREMENTIONED SYSTEMS WILL
LEAD TO A SLIGHT INCREASE IN SOUTHERLY FLOW. THIS ALONG WITH PARTLY
CLOUDY SKIES SUPPORTS MUCH WARMER TEMPERATURES TODAY. EXPECT HIGHS
GENERALLY IN THE MID 60S TO LOW 70S WHICH IS ABOUT 20 DEGREES WARMER
THAN YESTERDAY. WELCOME TO SPRING.
INCREASING DIURNAL MIXING WILL PROMOTE MINIMUM RH VALUES AROUND 25
TO 35 PERCENT DURING THE AFTERNOON AND BREEZY CONDITIONS AT
TIMES. SLIGHTLY ELEVATED FIRE CONDITIONS CAN BE EXPECTED INTO THE
AFTERNOON WITH DRYING FUELS.
DISCUSSION (TODAY THROUGH TUESDAY)
ISSUED AT 314 AM EDT WED APR 8 2026
THE COLD TEMPERATURES THIS MORNING WILL QUICKLY TURN TO ABOVE NORMAL
TEMPERATURES THE REMAINDER OF THE FORECAST PERIOD. THERE WILL ALSO
BE A FEW CHANCES FOR RAIN AND THUNDERSTORMS, FIRST COMES THE END OF
THE WEEK THEN ADDITIONAL CHANCES ARRIVE NEXT WEEK.
AT THE SURFACE, A LARGE HIGH PRESSURE SYSTEM IS CONTINUING TO PUSH
EASTWARD WHILE A COLD FRONT APPROACHES FROM THE NNW. THIS WILL SHIFT
WINDS OVER CENTRAL INDIANA TO OUT OF THE SOUTH BY LATER TODAY AND
WAA WILL TAKE OVER, LEADING TO HIGHS IN THE MID 60S TO NEAR 70 TODAY
DESPITE THE COLD START. DRY WEATHER IS EXPECTED TODAY WITH MINRH
VALUES NEAR 30% LIKELY THIS AFTERNOON WHICH WILL LEAD TO SLIGHTLY
ELEVATED FIRE CONDITIONS.
A LLJ WILL ALSO BE NEAR THE APPROACHING COLD FRONT, AND MIXING LATER
TODAY WILL LIKELY BRING WIND GUSTS NEAR 25 MPH FROM THIS AFTERNOON
ON, MAINLY IN OUR NW. MODELS ARE SHOWING THAT THE FRONT, WHICH IS
EXTENDING OFF OF A LOW TRACKING NORTH OF THE GREAT LAKES, WILL STALL
JUST TO OUR NW BY TONIGHT AND REMAIN THERE THROUGH AT LEAST TOMORROW
NIGHT. THIS WILL KEEP THE AREA UNDER PLENTY OF WAA AS WELL AS
MOISTURE ADVECTION ALLOWING TEMPS TO GET SOLIDLY INTO THE 70S ON
THURSDAY WITH DEW POINTS INCREASING INTO THE LOW 50S. DURING THIS
TIME SOME RAIN WILL BE POSSIBLE IN THE FAR NW, BUT CHANCES WON'T
INCREASE ACROSS THE AREA UNTIL THE FRONT FINALLY PUSHES SE THROUGH
THE DAY FRIDAY. AT THIS TIME RAIN AMOUNTS LOOK TO STAY BELOW HALF AN
INCH BUT CAN'T RULE OUT HIGHER AMOUNTS IN LOCALIZED AREAS. UNTIL THE
FRONT FINALLY PASSES, WIND GUSTS WILL CONTINUE TO BE A CONCERN
ACROSS CENTRAL INDIANA, WITH GUSTS UP TO 30 MPH POSSIBLE THURSDAY
AND UP TO 25 MPH FRIDAY.
BEHIND THE FRONT, ANOTHER SURFACE HIGH WILL BRING DRY WEATHER FOR
THE WEEKEND AS WELL AS A QUICK DROP IN TEMPS THROUGH SATURDAY BUT
STILL NEAR TO ABOVE NORMAL FOR THIS TIME OF YEAR.
MODELS SHOW AN ACTIVE PATTERN POSSIBLE FOR NEXT WEEK WITH SW FLOW
SETTING UP OVER THE AREA. TEMPS WILL PROBABLY BE A GOOD BIT ABOVE
NORMAL WITH HIGHS IN THE 70S TO NEAR 80 IN THE FORECAST. WHILE
TIMING AND DETAILS ARE UNCLEAR AT THIS TIME, THE NEXT ROUND OF RAIN
AND THUNDERSTORMS IS PROGGED FOR AT LEAST THE FIRST HALF OF NEXT
WEEK.
