Round two?

I'm still shocked by yesterday's pop-up tornado warning. I don't think we will see that today as dew points in the area are in the low 50's.

The local Herald Times reported that:
"The National Weather Service reported a tornado was spotted on the ground at 4340 North County Road 475 West in Worthington at 7:24 p.m. Tuesday."

That would be near here:



Tornado Sirens have ended (7:58pm)

The sirens have ended for now but we are not out of the woods yet. A Flood Warning has been posted for Monroe County Indiana until 10:30pm.

Tornado Sirens now in Bloomington, Indiana Tuesday 4/26/16 @7:50pm


Storm relative confirms. Heavy downpours and lightening at Starbucks on South Walnut.

Bow echo west of Bloomingon!


Tornado Warning for Monroe County Indiana!

Hmmmpf! I'm somewhat shocked by this! From the NWS Indy office:

Convective outlook for Tuesday 4/26.


Of climate science and "feminist glaciology".

This has been making the rounds. Very interesting questions for those interested in history, philosophy of science, climate science and gender studies. I wish Thomas Khun was available for comment on this.

Tuesday 4/26/16 Update

Current temperature is 83 degrees. The dew point is 61. A severe thunderstorm watch is in effect until 11:00pm tonight for southern Indiana.

There is a strong bow echo forming over the St. Louis area.



Tornadoes possible tomorrow in the great plains states.

Oklahoma, Kansas and Nebraska are facing a severe weather threat for Tuesday 4/26/16. Southern Indiana is in the marginal risk zone.

Smooth sailing.

The last two week have been fabulous. Expect more of the same. Highs in the 70's and lows in the 50's with intermitant thunder storms and showers.

4/8/16 Graupel in Bloomington, Indiana at 34 degrees.

The roof tops were slightly covered before 8:00am but as the temperatures rose the graupel melted.











The first picture shows the bank tower temperature of 35 degrees. The second picture shows graupel on the windshield of the car. The third video clip is of two small graupels falling. If you watch carefully, you can see them.

This Grateful Dead song is apt for Friday!

Cold rain and snow.

4/6/16: Today there is a wind advisory. Rain is likely tonight. A 996Mb low is located over eastern Michigan and tracking east-north east. This will drag down a cold front behind it. Temperatures and precipitation will vary over the next five days so dress appropriately. There is a 40% chance of a rain/snow mix on Friday. Not a big deal but it should be mentioned. We will be in a see-saw pattern for the next week to ten days. Here are some interesting things to look at:
