Weather Underground Forecast for Friday, May 24, 2013.

Showers and thunderstorms will move into the Plains, while also continuing across the East Coast on Friday. A low pressure system over the Rocky Mountains will persist on its eastward track and move into the Plains. Flow around this system will create northward flow, pulling abundant moisture and energy in from the Gulf of Mexico. This will allow for scattered showers and thunderstorms to develop across the Southern Plains again on Friday, spreading northward through the Central and Northern Plains. There is a slight chance that these storms will turn severe across northeastern Colorado, into western Kansas and Nebraska. Large hail and strong winds are likely in these areas, with possibly a tornado or two.

Meanwhile in the East, a trough of low pressure and associated cold front will slowly move eastward and offshore the East Coast on Friday. This system will allow for showers and thunderstorms to persist from the Mid-Atlantic states through Maine. Severe thunderstorms are not likely in these areas, but periods of heavy rainfall and strong winds will persist as this system lingers over the Northeast through Friday night.

Out West, an area of low pressure continues spinning over the Pacific Northwest, maintaining onshore flow. This will bring more rain showers to Oregon and Washington, with snow showers possible at highest elevations.

Tornadoes and Climate Change: Huge Stakes, Huge Unknowns

Posted: 12:05 PM EDT on May 23, 2013

We currently do not know how tornadoes and severe thunderstorms may be changing due to climate change, nor is there hope that we will be able to do so in the foreseeable future. It does not appear that there has been an increase in U.S. tornadoes stronger than EF-0 in recent decades, but climate change appears to be causing more extreme years--both high and low--of late. We may see an increase in the number of severe thunderstorms over the U.S. by late this century.

Weather History:

Did you know that...

A tornado safety expert would tell you to never try and outrun a tornado because the storm will probably catch you. Keeping that in mind, there are exceptions. In 1930, a tornado near Pratt, Kan. was clocked at 5 mph.
