Mid-Summer Taste of Autumn Next Week? Probably!
What is going on? Is it the revenge of the polar vortex? Actually, it’s probably connected to Japanese Typhoon Neogori that at one time was packing 260 kph winds. It is moving into southern Japan now, but the global weather models all indicate that it will push a lot of warm and humid air into the high latitudes north of Japan. This will push the jet-stream northward, and the downstream …

The Amazing Retrograding Low
It developed last Friday over Western Maryland, and brought 10 inches of rain to the coast of Delaware. Then it began to drift westward. This is not that unusual in the summertime, when an easterly wind can develop to the south of a strong upper ridge over North America. The easterly trade-winds form the same way, and steer tropical waves form the coast of Africa to the New World all …

NASA Climate Expert James Hansen & An Amazing Forecast
In 1988 James Hansen published a paper with a prediction that many of his fellow scientists thought was a bit over the top. I want to explain the prediction and then give a summary of the paper he published this week showing it was (almost amazingly) correct. Imagine that the odds of a cold winter, or hot summer, are represented by a 6 sided dice. Two sides are white for …

Tulsa Hits 108 Degrees Sunday- Forecast for Wednesday 113!
The temp. at midnight in Tulsa was 95 degrees after a high of 108 on Sunday. The heat goes on and on and on… FYI- the all time record for Tulsa is 116 degrees in the dust bowl August of 1936. From what I see on the numerical models tonight, that record is in jeopardy. Update 1 am EDT Tues. 31 July: Tulsa set an all time record high minimum …

Greenland Melt Was Predicted In Advance By Paper Awaiting Publication
The image above is based on data from the Indian Oceansat-2 satellite and shows that on 12 July 2012 virtually all of the Greenland ice sheet surface was melting. The highest point on the ice sheet, Summit at 3,200 meters saw temperatures at 36 degrees! The melt areas can be detected by the albedo of the ice sheet and this can be confirmed by a network of automated surface stations …

Last 12 Months In U.S. Are Warmest On Record. (A 1 in 1.59 million event)
The NCDC released the June temperature data today and while it was the 14th warmest on record, added to the 5 months before it make the first six months of the year the warmest on record. Not only that, but it is also the warmest 12 consecutive months on record. We still had a La Nina back in the fall so the warmth of the last 12 months worldwide is even more …

Strong Signs of El Nino Brewing In The Pacific (Global temps will likely jump to new records.)
Imagine you are slowly filling a bathtub with water, and are measuring how deep the water is at frequent intervals. Also imagine, that at times your dog jumps in while you’re measuring, and this of course causes you to get a higher water level. The dog gets back out, and the water level drops slightly, but not as much as it was before because the faucet is still running, and …

Colorado Wildfire Smoke Reaches U.S. East Coast
I could see the smoke in the air at sunset here in Salisbury, Maryland tonight as well. The folks at Climate Central has an interesting graphic that explains the wildfires. The much reduced snow pack has to be the main factor. The dead trees from the Pine Beetle most certainly are aggravating the situation. It was 108 (44.5C) in St. Louis today, and Indianapolis had the warmest June day on record. Records in Indianapolis go back to the …

All Time Records Tumble in Rockies and Plains. Fires Threaten NCAR.
The massive heat wave spread from Montana to Louisiana Tuesday with several more all time record highs broken. Hill City, KS and McCook, Nebraska hit 46 degrees C or 115 degrees F. Both, the warmest temperatures ever recorded in those cities. Winds gusted to 40 mph at Denver International and all along the front range of Colorado in the afternoon. Lightning from thunderstorms sparked wildfires and they grew rapidly. The …
