<p>Prolonged heavy rain is expected to begin Wednesday as strong storms and a cold front work across the Lower Mississippi and Ohio Valley. Several frontal waves will work through the area between Wednesday and Sunday, prompting a Flood Watch for a widespread region from Texarkana, TX to Columbus, OH.</p><p>Impressive rainfall totals and rainfall rates 2/3" per hour at times will cause rivers, creeks, and streams to run swollen. Urban flooding will be likely after saturated soils and always remember, Turn Around, Don't Drown. <span style="color: rgb(31, 31, 31)">Over half of all flood-related drownings occur when a vehicle is driven into hazardous flood waters.</span></p><p><img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-01 122030-1743531646459.png"><br></p><h1>DAY BY DAY</h1><h2>WEDNESDAY</h2><p><img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-01 134454-1743537276063.png">60-80% to pick up over 2 inches of rain.

<p>Severe chances have been easy to find in the past week or two. The month of March was littered with them to close, spilling right into April. A slow-moving frontal boundary will focus multiple storm days, leading to a flooding threat. On top of torrential rain, these storms can see damaging winds, large hail, and a few tornadoes. We're here to break it down by the day.</p><h1>Overnight Storms</h1><p>The Storm Prediction Center maintains an<strong> enhanced </strong>risk through the overnight hours for portions of Missouri, Kansas, and Oklahoma. Outside of the enhanced risk, we still see the potential for strong to severe storms continuing hrough the overnight hours. Always have multiple ways to get alerts and a plan in place now, as we see multiple days of strong to severe storms.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/04/tomer svr plains tonight-1743549456729.jpg">Our forecast model has the strongest of these storms moving through EARLY Wednesday morning, bringing stong multicell clusters and supercells to areas like Oklahoma City and Kansas City, so do not let your guard down while you're under the risk from the Storm Prediction Center.</p><video src="https://media.weathernationtv.com/app/uploads/2025/04/04-1_wide hrrr-1743561104342.mp4" controls="true" width="100%"></video><p></p><h1>Wednesday's Severe Outlook</h1><p>The Storm Prediction Center has issued a MODERATE (level 4 out of 5) risk for severe thunderstorms on Wednesday. </p><p><img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-01 135153-1743537145398.png"></p><p>As it stands, Wednesday is the closest to a severe weather outbreak this week. A well-built front will gradually slide east throughout the day. By the afternoon, all of the ingredients will be in place, helping power storms capable of large hail, damaging winds, and multiple tornadoes.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-01 135209-1743537180402.png">For Wednesday, the peak timeframe looks like it will be early afternoon into the overnight hours.</p><video src="https://media.weathernationtv.com/app/uploads/2025/04/FS-1743557165170.mp4" controls="true" width="100%"></video><p></p><h1>Thursday's Severe Outlook</h1><p>By Thursday, as storms run over the same areas, the instability may not be as high so the risk for severe weather is SLIGHT, a level 2 out of 5 from the Appalachian Mountains to the Red River Valley.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-01 135315-1743537199748.png"></p><p>Thursday is when things slow down. The front responsible for the severe chances on Wednesday will run into some opposition. A building high over the southeast will bring the front to a screeching halt for the second half of the week. Usually, this is where a forecast becomes clear as mud. Without a sure-fire bet to trigger storms, it's hard to nail down when/where severe chances might be. Will it be unusually warm and humid ahead of this boundary? Absolutely. Will ongoing rain limit the severe potential? Maybe. The flooding threat will start to skyrocket, with or without severe storms.</p><h1>Friday's Severe Outlook</h1><p><img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-01 064303-1743511392777.jpg">See Thursday.

We've got details to iron out between now and then.</p><h1>SATURDAY</h1><p>CTRL+C CTRL+V Friday, aka Thursday. The flooding threat could be approaching life-threatening levels by now.</p><p></p>

Wet & Snowy Western Storm System Through Wednesday

<p>Powerful storms raced through the Midwest and down to the Gulf Coast coming out of this weekend. Sunday afternoon into Monday morning, a strong line of storms spurred numerous Severe Thunderstorm Warnings and quite a few Tornado Warnings. Those storms produced hundreds of reports of damage, with a few tornadoes touching down. </p><p><img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-01 055103-1743508412691.jpg">One of those was early Monday morning as a segment of the line started to spin in southern Mississippi.

Slight Risk For Severe Storms Overnight

<p><strong>GREAT LAKES to NORTHEAST </strong>- As the freezing line hovers the international border, an ice storm continues to bring issues from the Great Lakes through the Northeast. Power outages continue to increase, and roads remain icy and slick across these areas. Pictured above, near Rogers City, Michigan, is an incredibly thick amount of ice that has accumulated on tree branches this morning.</p><h1>Upper Midwest to Great Lakes</h1><p>Crippling ice has already accreted in parts of Michigan with another batch on the way. Three-quarters of an inch of ice has led to numerous power outages and slippery roads around the Great Lakes.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/03/tomer power outtages mi wi-1743386582369.jpg">Gaylord, Michigan has received 0.75" of ice already today!</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/03/Screenshot 2025-03-30 132032-1743362571455.png"><strong>Ice storm warnings</strong> remain in effect through tonight across portions of Wisconsin and Michigan.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/03/Screenshot 2025-03-30 131904-1743362608324.png">Additional accumulations may still reach up to 0.5", enough to lead to additional power outages and nearly impossible travel. As we time this system out, the surface low will push its way farther north into Canada this evening. As temperatures drop behind this system, ice will transition to snowfall before wrapping up Monday morning. The commute Monday will still be dangerous and slick despite no active precipitation falling.</p><video src="https://media.weathernationtv.com/app/uploads/2025/03/tomer mi wi futurecast-1743386654760.mp4" controls="true" width="100%"></video><p>Stay safe in power outages - always remember to run a generator at least 20 feet from windows and doors to avoid carbon monoxide!</p><h1>New England</h1><p>The worst impacts for New England were earlier this Sunday morning as temperatures hovered around freezing.

The impacts through Monday remain moderate for New Hampshire and Maine, but the warm front has been lifting the freezing line north of the border, providing room for this icy mess to become more of a rainy mess through Monday.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/03/Screenshot 2025-03-30 131634-1743362716600.png"></p><p>Here's a look at the timing of ice transitioning to mostly rain through Monday.

How big are hailstones?  That definitely can depend on where you live and how strong an updraft the storm has that produces them!

<img class="alignnone size-large wp-image-89379" src="https://media.weathernationtv.com/app/uploads/2018/03/hail-1-728x408.jpg" alt="" width="728" height="408" />

The best way to find out how large the hail might be that fell in your yard is to take an actual measurement.

<img class="alignnone size-large wp-image-89382" src="https://media.weathernationtv.com/app/uploads/2018/03/hail-4-728x408.jpg" alt="" width="728" height="408" />

Depending on what the diameter is in inches will determine the size.
