While the severe thunderstorm risk ends with the latest system pushing off the Atlantic Coast, another potent upper trough will move into the middle states by the middle of next week. The Storm Prediction Center has already highlighted an area of potential severe weather on Thursday, across central Oklahoma and Kansas (above). <img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-18 192833-1776562725783.png">This upper-level low will bring strong winds aloft, enhancing shear for any storms that are able to form in the environment. <img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-18 192901-1776562838690.png">Meanwhile, at the surface, heat and humidity will build during the afternoons, creating an unstable atmosphere. Storms that form will strengthen quickly!<video src="https://media.weathernationtv.com/app/uploads/2026/04/nextweeksevere-1776562942155.mp4" controls="true" width="100%"></video>Longer range, less resolute models depict thunderstorms erupting each afternoon, beginning Wednesday. In addition, the models depict heavy rainfall during these events.<img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-18 193001-1776563093281.png">The WPC 3-7 Day Outlook has highlighted the threat of heavy rain from the Central Plains to the Gulf Coast from Thursday to Saturday, respectively.

After a quiet weekend, the next upper level low pressure moves in from Alaska. With the close proximity of the low just hanging off the coast, rain and snow chance will be increasing for Southern Oregon and Northern California!<video src="https://media.weathernationtv.com/app/uploads/2026/04/New Baron Video 3-1776454572613.mp4" controls="true" width="100%"></video>Heavy rain will be possible for Northern California especially Monday and Tuesday where a few inches will possible. As colder air drops for the Sierra, some snow chances will be possible too. Again this is good news as drought has returned to the state following the historic heatwave in March. As the low moves eastward midweek, more moisture should increase across the Rocky Mountain states. Models are starting to hint at some big snowfall for the Sierra. This will be such welcomed news after the decreasing snowpack the last 2 months.<img src="https://media.weathernationtv.com/app/uploads/2026/04/1-1776562858123.png">In the next week and half, the pattern should stay stormy which means more potential for snow and rain chances for California and the rest of the West. Temperatures will be slightly cooler than normal!<img src="https://media.weathernationtv.com/app/uploads/2026/04/1-1776562892864.png"><img src="https://media.weathernationtv.com/app/uploads/2026/04/1-1776562916732.png">

Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

Tornadoes, hail, wind, and rain slammed the Midwest and Great Plains on Friday as a powerful storm system moved into the region. The same storm system was producing snow in Colorado while tornado warnings were being issued hundreds of miles to the east. Unfortunately, tornadoes hit some residential areas causing damage to homes in several states and injuring at least one person in Iowa. Thankfully, no deaths have been reported thus far. We'll post summaries of the tornadoes, including their ratings, as that information comes in over the next few days.

The cold front that generated the severe storms in the Midwest and Southern Plains on Friday will keep moving east into the Ohio Valley on Saturday. The front will interact with more unstable and showers and storms could quickly turn severe. Not many severe warnings as the threat has been lowered to a Marginal. However, the biggest threat will be gusty winds.<img src="https://media.weathernationtv.com/app/uploads/2026/04/1png-1776546181046.png"><h1>Timing</h1>The cold front continue eastward towards the Interstate 95 region into the nighttime hours.

UPPER MIDWEST and GREAT LAKES - Three straight days of destructive severe storms moved through Iowa, Minnesota and Wisconsin. Wednesday, NWS Kansas City confirmed two EF-0 and EF-1 tornadoes that hit the city of Clinton, MO.

Some rough storms still remain possible across Arkansas and Tennessee that could produce some damaging winds and hail.

You might have seen a lot of talk today on social media about thundersnow with Wednesday's Nor'Easter.

So...what exactly is it, and how does it happen?

It's far less common to see thunderstorms in the winter months, but if all the conditions are right and we have lightning within a snowstorm, we call it thundersnow.

The ingredients you need include lots of available moisture and also instability in the atmosphere.

So next time you have a thunderstorm when it's snowing, you can tell your friends you are experiencing thundersnow!
