NATIONAL WEATHER SERVICE INDIANAPOLIS IN
258 AM EDT FRI JUL 10 2026
KEY MESSAGES
- CONTINUED THREATS FOR THUNDERSTORMS WITH HEAVY RAIN AND POSSIBLY
LOCALIZED FLOODING THROUGH SATURDAY; AN ISOLATED STRONG STORM
WITH DAMAGING WINDS CANNOT BE RULED OUT
- WARMER AND DRIER AGAIN NEXT WEEK, THOUGH WITH MORE MODEST HUMIDITY
THAN EXPERIENCED THE FIRST WEEK OF THE MONTH
DISCUSSION (TODAY THROUGH THURSDAY)
ISSUED AT 257 AM EDT FRI JUL 10 2026
TODAY INTO SUNDAY -
SOME PATCHY FOG AND LOW CLOUDS WILL BE POSSIBLE NEAR DAYBREAK INTO
THE MORNING HOURS TODAY, WITH A RELATIVE LULL IN CONVECTIVE ACTIVITY
EARLY TODAY.
AN UPPER LEVEL WAVE WILL MOVE SLOWLY THROUGH THE REGION LATE TODAY
INTO SUNDAY, THOUGH MODELS DIFFER IN THEIR HANDLING AND INTENSITY OF
THE DISTURBANCE. A CONTINUED MOIST AIRMASS WILL PROMOTE AT LEAST
MODEST DESTABILIZATION, AND ONE OR MORE CLUSTERS OF STORMS WILL BE
POSSIBLE, PRIMARILY LATER TODAY INTO TONIGHT THOUGH THE THREAT WILL
LESSEN AND SHIFT SOUTHWARD WITH TIME, AND BE FOCUSED PRIMARILY ALONG
REMNANT BOUNDARIES FROM PREVIOUS CONVECTION, LIMITING THE
PREDICTABILITY. THE BULK OF CONVECTIVE ACTIVITY SHOULD BE SOUTH OF
THE AREA BY SATURDAY NIGHT.
AN ISOLATED STRONG TO SEVERE THREAT CANNOT BE ENTIRELY RULED OUT,
THOUGH HYDRO CONCERNS WILL LIKELY BE SLIGHTLY MORE PRESSING AS THE
AREA HAS BEEN DECENTLY WET IN RECENT WEEKS, AND THE AFOREMENTIONED
PLENTIFUL MOISTURE COMBINED WITH WHAT MAY BE FAIRLY SLOW STORM
MOTIONS OUTSIDE OF MORE ORGANIZED CLUSTERS COULD PRESENT A LOCALIZED
FLASH FLOOD THREAT - WPC EXCESSIVE RAINFALL OUTLOOKS OUTLINE THIS
WELL. DEEP LAYER SHEAR IS RELATIVELY WEAK FOR THE MOST PART AS WELL,
THOUGH IF ANY COLD POOLS CAN BECOME ESTABLISHED, THIS MAY NOT BE AS
IMPORTANT WITH DECENT INSTABILITY TO WORK WITH.
00Z HRRR SOLUTION DOES SHOW A LINE SEGMENT CLIPPING FAR SOUTHWESTERN
PORTIONS OF CENTRAL INDIANA THIS EVENING WITH A LOCALIZED DAMAGING
WIND THREAT, AND THIS WILL REQUIRE MONITORING, BUT AGAIN THE
LOCALIZED HYDRO CONCERNS ARE MORE PRESSING GIVEN CONTINUED
PRECIPITABLE WATER VALUES NEAR OR ABOVE 90TH PERCENTILE THROUGH MUCH
OF THE WEEKEND.
NEXT WEEK -
THE PREDOMINANT STORY NEXT WEEK WILL BE A REASSERTION OF SUMMERTIME
HEAT AS A BRIEF PSEUDO-REX BLOCK PATTERN FORMS WITH THE WESTERN
CONUS RIDGE SLIDING BACK EASTWARD ATOP WEAK UPPER LEVEL LOW PRESSURE
TO OUR SOUTH, GRADUALLY RECONNECTING WITH THE BERMUDA HIGH OVER THE
SOUTHEAST. TEMPERATURES WILL CLIMB BACK TOWARDS THE 90 DEGREE MARK
IN SPOTS, THOUGH WITH SLIGHTLY MORE REASONABLE DEWPOINTS THAN THE
FIRST WEEK OF THE MONTH, KEEPING MAX APPARENT TEMPERATURES STILL
TOASTY BUT FAR MORE MANAGEABLE IN THE LOW TO MID 90S.
THE HIGH PRESSURE ALOFT AND AT THE SURFACE WILL KEEP THE AREA DRY
FOR THE MOST PART, THOUGH AIRMASS THUNDERSTORMS CANNOT BE ENTIRELY
RULED OUT NEAR PEAK HEATING MANY DAYS. THAT SAID, THESE ARE QUITE
LOW PREDICTABILITY DAYS AHEAD OF TIME AND WILL NOT MERIT AT MOST
SLIGHT CHANCE AFTERNOON POPS LATER IN THE WEEK.
