Record heat wave bakes Republican southern states
Oh yeah, what happened to the right-wing pseudo-scientists who are bashing on global warming because of a snow storm? What do they have to say about these record high temperatures set in 2011?
Extreme heat wave to spread across U.S., drought conditions to worsen
Already during July, 882 record high temperatures have been tied or set across the U.S. At the same time, drought is more extensive than any time since at least 2000. Over the weekend and next week, the drought will worsen in many areas while a remarkable burst of humid heat surges north and then east.
The U.S. Drought Monitor released Thursday showed 29 percent of the country in drought, and 12 percent of the country in exceptional drought, the largest extent on record (though records only go back to 2000).
The drought conditions covering large sections of the U.S. have evolved very quickly. A year ago, there was essentially no extreme or exceptional drought over the U.S. The New York Times has an excellent illustration showing the evolution of “extreme to exceptional” drought over time
Of all states, drought conditions continued to be most extensive and intense in Texas, with 72 percent of the state in exceptional drought. But drought conditions have rapidly expanded in Oklahoma, where exceptional drought now covers 40 percent of the state, a marked 10 percent increase from last week.
In the south central U.S., the drought and heat go hand in hand. At weather.com’s blog, meteorologist Stu Ostro, explained the self-reinforcing cycle:In the southern states, particularly the southern Plains, afternoon high temperatures have consistently been particularly extreme, assisted by how dry the soil is. Rather than some of the sun’s energy going into evaporating soil moisture, it gets efficiently converted into quickly-rising temperatures each day.
And in turn, the soil dries out even more, worsening the drought.
Heat Index Rises: Hot Weather Hits Midwest, South
There is no need for a campfire this summer in parts of the United States: Just go outside and watch those marshmallows roast themselves.
This weekend's raging heat wave will linger into the upcoming week, threatening to set existing high temperature records ablaze.
Seventeen states have heat warnings in effect for the upcoming week and 36 states are expected to see temperatures at or above 90 degrees today.
A high pressure system anchored over the Great Plains will produce sizzling temperature in the 90s and 100s from Texas through the Upper Midwest and Accuweather predicts that the plains and Mississippi Valley will feel the brunt of the blazing temperatures.
