We are in the clear, the entire viewing area is rain-free & calm. No watch for areas of dense fog area-wide as skies clear. Lows will drop into the 60s.
RAINFALL TOTALS FOR TODAY-TONIGHT:
(Gusts Measured or Estimated at or Above 40 mph)
E60 mph Tipton
M50 mph White County Airport AWOS
E50 mph 3 Miles Northeast of Battle Ground
M45 mph Frankfort
M44 mph Purdue University Airport ASOS
Americus: Tree Down, Partially Blocking Old Route 25
0.75″ Hail: 10 Miles East of Crawfordsville:
0.25″ Hail: East of Frankfort
0.25″ Hail: Tipton
Tipton County storm has gusted out. Second microburst signature evident on radar in the eastern part of the county.
Last storm is an intense one over Tipton County at the moment. Microburst possible with gust to 60 mph. Pea hail also possible with +2″ per hour rainfall rates.
Chuck northeast of Frankfort measured 1.43″ of rainfall in 90 minutes. Randy Rogers on the east side of Frankfort reported pea hail.
The Boone & Clinton County storm masses have completely congealed & now they will likely fall apart over the next hour.
A tree is blocking part of Old 25 near Americus, north of Buck Creek, in northeastern Tippecanoe County. Law enforcement is on scene & highway department is en route, per dispatch. This was the wind core we were tracking from Battle Ground to Buck Creek.
Storm mass in Clinton County is showing signs of collapsing rapidly, but not before belching out a gust of 50-55 mph southeast of Frankfort. This is visible on radar. Pea hail is also possible with it.
Flood Advisory in effect for Clinton, southern half of Carroll, northeastern Tippecanoe & western Howard County until 12:30 p.m. Doppler radar estimates 2.30″ of rainfall in the past hour in north-central Clinton County.
The storms have morphed/congealed into cluster over Clinton County & they are in the process of morphing/congealing with the storms moving north out of Boone County. Torrential rains are likely at the two gell & dump their load before collapsing. The storms are being accompanied by nearly continuous lightning.
Wind may gust 40-50 mph south of Frankfort. Pea hail is also possible.
Boy, as quick as the storms blew up on ouflow of White County storm, they have largely collapsed. Now, the new storms are occurring from Owasco to Mulberry to Concord, Monroe & Frankfort. These are likely peaking now & weill gell into a mass, then collapse to just some rain & thunder/lightning before completely dissipating.
A mass of storms has formed in Montgomery/Boone & may actually haphazard move north & gell with the Clinton County storms to form a mass of storms with torrential rainfall. Flash flooding may develop quickly over the next hour in Clinton County.
With no strong dynamics, the storms are CAPE & outflow-driven, moving about haphazardly…………….collapsing here, pulsing there, then gelling here & there & then raining themselves out.
For example, 40 minutes ago, White County was getting hammered & they are nearly completely rain-free now!
White County part of storm has collapsed, but new storm on outflow in Tippecanoe County is sagging through Battle Ground & Buck Creek toward Laf/West Laf. Also, new t’storms are pulsing up from Cutler to Mulberry to Frankfort, Dayton & Concord.
White County Airport AWOS measured a gust of 50 mph.
Brief gust of 47-55 mph possible southeast of Battle Ground around Buck Creek & northwest of Heath.
Looks like NWS has brief Severe T’Storm Warning for southeastern White County, but storm is rapidly collapsing & building more on its southern flank (outflow boundary). Look like as it re-evolves & becomes outflow-driven, it is sagging more toward Battle Ground & Buck Creek to perhaps West Lafayette/Lafayette.
Gust 55-60 mph possible southeastern White County/northwestern Carroll County with torrential rainfall.
Torrential t’storm working through the southern half of White County & far northwest Tippecanoe County. Rainfall rates of up to 3.5″ hour are likely. Gust to 55 mph possible near Chalmers with the storm visible on radar velocity. Some pea hail is possible.
Torrential t’storm is moving through eastern Benton County between U.S. 52 & I-65. Rainfall rates of +2″ per hour, brief gust to 50 mph & pea hail are possible. The worst core of it will pass from northeast of Benton Central High School to over the U.S. 231/I-65 interchange, eastward to Chalmers & perhaps Brookston.
Clinton County storm is just beginning to collapse.
Some +2″ per hour rainfall rates are occurring in southern Newton & Jasper County to central Benton County. Flood Advisory is in effect for southern Newton, Jasper & northern Benton until 9:30 p.m.
The strongest pulsey storm (could belch out a gust to 50 mph) is in central Benton County. Some pea to marble hail is possible there, too.
All of these storms are moving due east toward White & northwestern Tippecanoe County.
Heavy t’storm is also approaching Forest in Clinton County.
0.75″ diameter hail was reported east of Crawfordsville, near the Boone County line.
New scattered pulsey storms are popping again. Like this afternoon, these storms quickly pop & intensify, then collapse, while a few new ones form nearby. These storms & processes will be with us during the evening, then they will fade away.
Isolated severe wind gusts/hail still cannot be ruled out.
This is a result of re-charge as the sun comes out with the front in vicinity & up to 4500 residing in southeastern Illinois that is advecting some northward. Dynamics are not good enough or organized, widespread, longer-lasting storms.
M44 mph Purdue Airport ASOS
M32 mph WLFI-TV
T’storms are in weakening mode in our eastern counties with new storms pulsing up southeast & east of the viewing area. New spotty t’storms are popping in southern Montgomery County where temperatures are around 88 degrees with dew points around 72.
Will still maintain some scattered storms for the evening forecast & that isolated severe wind/hail threat.
Pulsey storms are tending to collapse in Carroll/Clinton counties.
Will keep a few scattered t’storms in the forecast for the evening as skies clear from west to east. Some heating/re-charge will bring the potential of a few more popping up.
The night looks dry with that patchy dense fog developing.
The core of the rainfall is Tippecanoe County as of 4:10 p.m. Some sporadic gusts of 40-50 mph are possible with the t’storms. Measured a very brief, sudden gust to 32 mph at WLFI.
The same areas are getting the heavy rainfall AGAIN!
The south & southeast sides of Lafayette are largely dry AGAIN, but West Lafayette is getting a torrential downpour.
More is coming in from the west, too.
It is very spotty in areas that need the rain. The storms are very sporadic & pulsey there.
We will see if the t’storms can hold together over Tippecanoe/Fountain & more pop to bring some rainfall to our east & northeast.
Storm north of Covington has weakend some, but is still putting out tremendous lightning & heavy rainfall.
Other storms are dotting the area.
There is a 90% chance of pea to marble (perhaps to penny) hail in southern Warren County to north of Covington in Fountain County.
Gust of 30-40 mph is also possible with the storm.
Scattered multi-cells of 40% will continue to pop. Some of you will get a nice downpour, some of you absolutely nothing.
Scattered t’storms are found across the area. SPC has Severe T’Storm Watch for Fulton County, but feel like severe threat is isolated for wind/hail. The strongest storm right now is well southwest of that watch, west of Covington.
