|Thursday Weather Outlook|
3 PM EDT, October 1, 2014
By WeatherBug Sr. Meteorologist, James West
|The U.S. weather pattern is in big transitions Thursday, with thunderstorms and summer-like heat rubbing shoulders with autumn showers and temperatures. |
A large storm system extending from the Gulf Coast and southern Plains all the way into the Upper Midwest and western Great Lakes will be the catalyst for big problems Thursday. Showers and embedded strong-to-severe thunderstorms producing gusty winds and downpours will expand across the Mississippi Valley and western Great Lakes Thursday afternoon, soaking Chicago, St Louis, and Kansas City. The storms will extend into the Mid-South by Thursday afternoon and evening. Temperatures, even with the storms, will be in the 90s across the lower Mississippi Valley, with 80s found throughout the central Mississippi Valley and the western Great Lakes.
Cooler and drier autumn air in the storm`s wake will produce afternoon highs in the 50s and low 60s throughout the northern and western Plains, Rockies, Intermountain West and the Pacific Northwest. A weak late-day system could produce showers across the northern Rockies, with a few high elevation locations seeing a wintry mix.
The Southwest, as well as southern and central California, will see highs in the 80s and low 90s under plenty of early-October sunshine.
The eastern third of the U.S. will continue to be locked in slightly warmer-than-normal pattern. Highs will easily reach into the upper 80s across the Mid-South and Southeast, with the Mid-Atlantic seeing upper 70s and low 80s and New England seeing highs in the 70s. Plenty of sunshine will be the norm with the exception being Florida, where afternoon thunderstorms will once again dominate the Sunshine State.
