<p>If it seems like April has been particularly busy with severe weather, that would be correct - except for two days, each day has seen some severe weather. Nearly half of those days have been Level 3 or higher. Related Article - <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/severe-weather-returns-to-the-plains-thursday-friday"><strong><em><u>Friday's Severe Weather Threat. </u></em></strong></a>Storms on Saturday are in nearly the same locations of the last few days, so please do not become a victim of severe weather fatigue. </p><h2>Saturday</h2><p>Our storm threat on Saturday is an <strong>ENHANCED</strong> (level 3 out of 5) risk that extends from Des Moines, IA, to farther south through Wichita Falls, TX. The southern threat will be more potent, with damaging hail and tornadoes possibly occurring. Storms ongoing in the morning in the Great Lakes region will be leftover from Friday's storm threat. The afternoon's heat will help develop storms once again in the Plains - these linger into the overnight hours and ultimately into Sunday morning, too. This means you must have multiple ways to get weather alerts, which need to be able to wake you up.</p><video src="https://media.weathernationtv.com/app/uploads/2024/04/2024-04-26 12-27-42-1714156195444.mp4" controls="true" width="100%"></video><h2>Sunday</h2><p>More severe weather looks likely on Sunday as the front hits warm, moist air over the central and southern Plains.

<p>Temps are climbing in the Northeast, and by early next week, the frost start of the last few days will be in the rearview. We have one more chilly morning though across New England with lows at or below 32° from the Massachusetts coastline back inland, where there are frost alerts in effect through Saturday morning. </p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/frost-1714166492389.jpg">Temperatures climb, though by Sunday and Monday, thanks to a ridge of high pressure in the Gulf of Mexico sliding north, and southerly flow arrives into our region, boosting temperatures.</p><video src="https://media.weathernationtv.com/app/uploads/2024/04/2024-04-26 08-55-00-1714144926800.mp4" controls="true" width="100%"></video><p>Highs jump into the 70s and even the 80s for major cities in the Northeast, from Louisville to Boston, with D.C. approaching 90!

From frosty temps to Record Warmth in the Northeast

dcjpg-1714166551791.jpeg

<p>Snow is on the way for the Intermountain West this weekend and potentially, but less likely for Denver, Salt Lake City, and Cheyenne, WY. An area of low pressure arrives from the Pacific through the weekend, tapping into moisture to bring low-elevation rain and high-elevation snow. Winter alerts have been issued for the southern Cascades, Wasatch, Colorado Rockies, and the Northern Rockies through Sunday. </p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/winteralertsjpg-1714133039383.jpeg">Widespread showers are expected in the West on Friday, with snow showers at the highest elevations possible. Energy then slides into the central Rockies Friday through Sunday, turning rain to snow by Saturday morning in the Colorado Rockies and Wasatch. With scattered showers, it will be a soggy stretch for much of the West. Snow levels drop as low as 7,000 feet in elevation on Saturday as temperatures cool. The low-pressure system responsible for the wet weather will slowly exit to the Plains, so expect lingering rain and snow showers into Monday for Wyoming and Colorado.</p><video src="https://media.weathernationtv.com/app/uploads/2024/04/2024-04-26 12-33-20-1714156432181.mp4" controls="true" width="100%"></video><p>The heaviest snowfall will range over 10k feet, with the potential for 12" or more snow. Even down to 7k (foothills outside of Denver), we could see over 6" of snow. Traveling on I-70 will be difficult, but the fresh snow will help ski resorts that are still open, like Breckenridge. We will unlikely see snow in the cities of Denver and Colorado Springs, with heavy rainfall more likely. On average, the Mile High City sees its last snowfall on April 28th. </p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/snow accumulation-1714133746187.jpg">As mentioned above, cold air will follow our front, bringing temperatures to frosty lows on Sunday and Monday. The 30s are expected to return to the Dakotas, Nebraska, and the Front Range of Colorado. There will be a sharp cutoff of freezing temperatures thanks to our front but expect lows to drop for everyone as the front pushes east early next week.</p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/Screenshot 2024-02-26 113946-1714133806213.jpg">Stay with WeatherNation for the latest information on our warm temperatures and weekend snow potential.</p>

Spring Snow on the Horizon in Colorado

cosnowjpg-1714141675745.jpeg

<p>A critical fire risk is in place for west Texas, eastern Colorado, and New Mexico through the next few days as gusty winds and dry grasses and low humidity create a dangerous situation. If a spark were to start, these are the conditions where rapid, life-threatening fire growth would be possible. Humidity values will be in the single digits and teens, meaning there will be no moisture in our atmosphere to help taper fire growth.</p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/Screenshot 2024-02-26 113946-1714134189244.jpg">Strong winds are anticipated on Friday, especially through New Mexico. Winds will be sustained along the Front Range of New Mexico and Colorado between 30-50 mph with isolated wind gusts over 65 mph. If a flame starts, it will move as quickly as the winds, at about 40 mph. We can't stress enough how critical this week's fire risk is.</p><video src="https://media.weathernationtv.com/app/uploads/2024/04/forecast-1714134246383.mp4" controls="true" width="100%"></video><p>Drought conditions are extreme and exceptional for southern New Mexico, while most of the region is experiencing moderate drought.

Critical Fire Risk in West Texas, New Mexico

<p>More people die from heat every year than ALL other extreme weather COMBINED. So how do you know how hot it is it <em>really</em> going to be?&nbsp;The National Oceanic and Atmospheric Administration [NOAA] and the Centers for Disease Prevention and Control [CDC] worked collaboratively to produce a new HeatRisk tool rolling out this summer from coast to coast. The tool had previously been used on the West Coast, but the 2024 summer will bring this experimental product to all cities across the U.S. </p><p>According to <span style="color: rgb(36, 36, 36)">Kimberly McMahon, the NWS Public Weather Services Program Manager, "HeatRisk is a great tool to just put into context, how hot it's going to be compared to what they're used to." </span></p><p><span>The HeatRisk scale ranges from minor to extreme impacts and is color-coded from yellow to magenta. For reference, a MINOR impact day is your typical summer day.&nbsp;MODERATE days bring impact to vulnerable populations, especially people who are in the sun for long periods or without A/C. On these days, fans and open windows help to alleviate heat impacts inside.</span><span style="color: rgb(0, 0, 0)">&nbsp;</span></p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/major-1713896597233.jpg"><span>MAJOR impact days can be deadly for those without A/C and power interruptions are possible due to the heat stress. Hospitals are likely to see an increase in the number of ER visits due to heat-related illnesses. Outdoor activities should be shifted to cooler times of the day.</span><span style="color: rgb(0, 0, 0)">&nbsp;</span></p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/mod-1713896597231.jpg"><span>Finally, EXTREME impact days are for long-duration or potentially record-breaking heat events. There will be little to no relief from the heat overnight... and power outages are likely due to the stress on the grid. Outdoor activities should be canceled, and you should stay in cool spaces.&nbsp;</span><span style="color: windowtext">&nbsp;In 2023 during Phoenix's month-long stretch of 100°+ degree days, more people died in their un-air conditions homes than outdoors. </span></p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/xtreme-1713896597235.jpg">The HeatRisk tool incorporated heat forecast and historical data from NOAA to include: how above normal the temperatures are, the time of year, the duration of the heat, and overnight relief potential.<span style="color: rgb(0, 0, 0)">&nbsp;It also considers at what temperature heat deaths occur for over 700 cities in the U.S.. That data was imperative in designing the tool to know at what level heat becomes deadly, unique to geographic location. For example, Phoenix's 110°, though hot, wouldn't be an "extreme" day during the summer. Take that same 110° but for Chicago? The risk becomes extreme. </span><span>Look for the new HeatRisk product and temperature forecasts this summer on WeatherNationTV.

<p>It’s the soundtrack to the summer. Nature’s noisemakers are set to return in a <em>big</em> way this year as not one, but <em>two</em> sets of periodical cicadas will emerge in the Midwest and Southeast. It is the first time these two specific broods have surfaced <em>together</em> since 1803! This is the first time since 2015 that a 13 year cycle brood emerges at the same year as a 17 year brood.</p><div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/o5jJPrP5rfE" start="0"></iframe></div><p></p><p>The southern brood emerges every 13 years and is known as the <strong>Brood XIX, </strong>the largest brood in the U.S.. The Northern Illinois brood has a period of 17 years, making these two broods overlap uncommon. They will only overlap in central Illinois, where is expected to be the noisest!</p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/Closer look at Illinois locations overlap.mp4_snapshot_00.01.232-1713196589008.jpg"></p><blockquote><p>Katie Dana, a researcher with the Illinois Natural History Survey who studies the cicadas says, “We have broods emerging across the U.S. almost every year, but we don’t often have broods emerging at the same time. Just like how birds have different songs, cicadas have different songs...we have over 3,000 different species of cicadas so we have so many different songs.”</p></blockquote><p>Periodical Cicadas are large, loud insects with bright red eyes. They live underground for years. Once the cicadas take to the skies, they will be in the air for about 3-4 weeks, mating before laying eggs and reburying themselves for another 13 or 17 years.</p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/Slow zoom east coast brood locations.mp4_snapshot_00.06.391-1713196589005.jpg">Depending on where you live, the double brood emergence could start as soon as April but will happen whenever the ground temperatures reach 64°. According to Katie, “It’s those warm soils that push them out of the ground, but they’re also looking for some moisture. If you have really dry soil, it’s going to make it hard for them to dig out.” Given that we've had some of our warmest winters on record in the Midwest we are looking at the opportunity for earlier emergence of the broods.</p><p><img src="https://media.weathernationtv.com/app/uploads/2024/04/Warmest Winter on Record.mp4_snapshot_00.05.538-1713196589007.jpg">If you’re less than thrilled about these beaty-eyed bugs, focus on the positives. They provide extra nutrition for birds and animals and spark a reset for oak trees allowing them to produce more acorns a few years after they emerge. If that’s not enough to get you through... the next time these two broods will be out at the same time won't be for another 221 years, which will give you plenty of time to learn to appreciate the cicada screams.</p>

Every day, WeatherNation brings you weather information to keep you safe. Every week, John Van Pelt helps get you prepared long before bad weather hits. This week we are talking about the dangers of long term flooding.

https://youtu.be/rN4daaZsij0

<strong>Q: We know that coming in behind heat, which is number one, flooding is the number two weather related killer in the U.S. What are the different kinds of flooding we need to be aware of?</strong>

Flash flooding is caused by thunderstorms inundating an area with several inches of rain in a short period of time. Tropical flooding is related to Tropical Cyclones bringing extreme amounts of storm surge and fresh water flooding. Areal and river flooding take longer periods to happen and cover larger areas.

<strong>Q: So when we see flood watches and other alerts being raised for where we are, what do we need to do to protect ourselves and our families?</strong>

A watch means flooding is possible, a warning means it's time to take immediate action. Seek higher ground and stay as far from flood waters as possible. Watch out for downed or live power lines. Never drive through flooded roads. Turn around, don't drown! Stay weather aware and have a safety plan, kit in place.

<strong>Q: Many people think that since they've never experienced a flood at their home, that they never will... that's not always true though, is it?</strong>

If it can rain, it can flood. Flood insurance is the first line of defense. For a small investment, you can be protected from these events.
