It has been an interesting day!  From a sunny, mild morning to midday, to building cumulus clouds with convective, low-topped showers with some graupal & even partial virga (part of the rainfalldrying up on the way down) to howling winds & convective gusts +60 mph in places (amidst already strong general winds of 40-50 mph).  Then the cold arrived quickly & with some rain & snow showers in places.

There are multiple reports of trees & powerlines down in parts of the viewing area. Reports have been received from Benton, Newton, Tippecanoe, White, Clinton & Fountain counties.

My hoophouse greenhouse was destroyed & our heavy 100 lb. grill pushed & thrust 100'.  Some surrounding homes to ours had some strips of siding removed by the wind.  During the peak gusts, the air was filled with dust with pieces of corn leaves from fields several miles away blowing in......all while it sprinkled a bit.  It felt like some one opened a refridgerator when in these peak gusts as the turbulent, rain-chilled, dry air hit the ground.  I estimate a wind gust here at the house of 65 mph.

Reported wind gusts in the viewing area (E = Estimated by spotter, M = Measured by anemometer at proper height on proper site.)

Farmers provide a good base of our observations with their properly-sited weather stations.  All stations from farmers with the sensors on their farmers in blue.  A BIG thanks to you all for your vital data!

Frankfort Muncipal Airport 15-mintue Observations 12:55 a.m. to 6:15 p.m..........Note the temperature drop from 61 at 2:55 to 42 by 5:35 p.m.

The measured wind speeds & gusts measured at the time are in red. Peak gust is in pink. Note the gust of 56 mph during a nearby light rain shower.  Dew points rose from 21 to 30 as the rain shower passed nearby.

This dry air was key in the really intense gusts as low-topped convective showers with the cold front & strong, cold upper trough rained into the very dry air closer to the surface.  The evaporative cooling only enhanced the downdrafts of the showers that tapped into the already strong wind fields.

These strong wind fields occurred also as low pressure deepened to our northeast & high pressure also approached & strengthened to our northwest.  This may for a funneling of the winds into the area as the pressure gradient tightened.

Purdue University Airport Hourly Observations 10:54 a.m. to 7:54 p.m. ...............Note the temperature drop from 58 at 12:54 & 1:54 to 40 by 4:54 p.m. & 38 by 6:54 p.m.!

The measured wind speeds & gusts measured at the time are in red.  Peak gust is in pink at observation times.  Note the gust of 63 mph during that light rain shower.  Peak gust was officially 64 mph at the airport.

Note that dry air with temperature in mid 50s & dew point in lower 20s as shower approached.  The evaporative cooling enhanced the already strong gusts.  The bits of buoyancy (heating from the sunshine with the cold air aloft) also helped to get gusts to +60 mph to the surface.
