From Freezing Rain to Giant Hail, Great Plains Endure An Icy Weekend

By: Bob Henson, 16:47 GMT dnia 16-styczeń-2017

Freezing rain materialized as expected during the weekend over a large swath of the central U.S., from Texas to Illinois. The ice has been widespread and prolonged, yet the ingredients haven’t come together as they could have for an truly catastrophic ice storm. Temperatures have been borderline--near or just below freezing over large parts of the affected area--and in many cases the ground was still warm enough to help keep surface ice to a minimum. Rainfall wasn...

Icy Weekend for Central Plains; La Niña’s Days Are Numbered

By: Bob Henson, 17:33 GMT dnia 13-styczeń-2017

Near-record levels of moisture for January will be flowing toward the Central Plains this weekend atop a paper-thin cold air mass at the surface--a classic set-up for widespread freezing rain. Ice storm warnings were in place Friday morning along a strip from northwest Oklahoma to southwest Illinois. These warnings indicate that enough freezing rain is expected in the next 12 to 36 hours (typically 1/4” to 1/2”, depending on location) to cause significant proble...

As Earth Warms Up, The Sun Is Remarkably Quiet

By: Bob Henson, 20:09 GMT dnia 11-styczeń-2017

If you’re looking toward the sun to help explain this decade’s record global heat on Earth, look again. Solar activity has been below average for more than a decade, and the pattern appears set to continue, according to several top solar researchers. Solar Cycle 24, the one that will wrap up in the late 2010s, was the least active in more than a century. We now have outlooks for Cycle 25, the one that will prevail during the 2020s, and they’re calling for a cy...

Second-Warmest Year in U.S. Weather History, and Among the Wettest

By: Bob Henson, 17:33 GMT dnia 10-styczeń-2017

Only 2012 ranks ahead of 2016 for average global temperature across the 48 contiguous states, said NOAA’s National Centers for Environmental Information on Monday in its yearly U.S. climate report. The second-place showing follows a third-place ranking in 2015 (see Figure 1), which means that the last five years (2012 - 2016) have produced the three warmest years in U.S. records extending back to 1895. This national-scale warmth is a reflection of global-scale tre...

Winter Storms Hustle Across United States; Ice Potential Rears Its Head for Late Week

By: Bob Henson, 19:00 GMT dnia 09-styczeń-2017

The much-anticipated twin winter storms affecting the U.S. West and East Coasts over the weekend brought many, if not most, of the predicted impacts. A nose of warm air pushed further inland than expected over the Southeast, which kept snow totals near the low end of hopes and/or fears from northern Georgia (central Atlanta missed out completely on snow accumulations) to southeast Virginia. Update: Parts of the Hampton Roads, VA, area picked up less than 6", but upd...
