<p>Lala is heading toward Hawaii and could be at hurricane strength as it moves close to the Big Island this weekend. Residents' preparations should be complete, as impacts will escalate quickly Saturday. Heavy rain will likely cause flooding and will probably be the biggest issue, especially on the east side of the Big Island.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-15 041616-1786788988748.png"></p><p>Lala's intensity hasn't changed much in the last 24 hours, with gradual strengthening occurring. It is expected to strengthen and is expected to reach low end category 1 strength as it passes the Big Island. If the center of circulation goes over the Big Island as a category 1 hurricane, it will be the first time a hurricane has made landfall on the Big Island in the satellite era.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-14 214828-1786765750744.png"></p><p>A Hurricane Warning has been issued for the Big Island. Tropical Storm Warnings have been added for Maui and all other islands.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-14 214457-1786765516348.png"></p><p>Tropical storm and even hurricane conditions could reach portions of the state as the system moves through, even if the center does not move directly over an island. If the eye of the storm stays south of the islands, the higher wind impacts will be felt on the east side of the Big Island, as the front right quadrant sees the strongest winds. Tropical storm winds will start to impact the islands early Saturday, spreading west through Sunday.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-14 215304-1786766030834.png"></p><p>Flooding will likely be the biggest threat with this system, as terrain enhanced rain could top a foot of accumulation on the Big Island. When heavy rain saturated soils, trees can be toppled more easily. Tropical storm force winds could have bigger impacts in this scenario.<img src="https://media.weathernationtv.com/app/uploads/2026/08/1-1786673304241.png"></p><p>Beach conditions are also expected to deteriorate as Lala gets closer. Larger swells generated by the system could lead to increasing surf and dangerous conditions along exposed coastlines.<span style="color: rgb(36, 36, 36)">&nbsp;High Surf Warnings are in place for most eastern facing shores.</span></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-14 215314-1786766061651.png"><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-14 215329-1786766061650.png"></p>

<p>The Atlantic basin still has a few areas to monitor for tropical development over the next several days. The chances for tropical development have drastically decreased over the last few days. One wave moving into the Caribbean and another trailing it still has the attention of the National Hurricane Center.<br></p><h1>Atlantic</h1><p>First, Invest 92L continues to move westward into the Caribbean. Blustery but beneficial rain will still be possible for areas of the Eastern Caribbean. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-15 043303-1786789990975.png"></p><p>Invest 94L has a low chance of developing into a tropical depression in the next few days. Similar to 92L, there may be a small window for development before running into hostile conditions next week. Models are pulling this system east of the Caribbean, keeping it in the open waters of the Atlantic. </p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/PIC 2-1786750556605.jpg"></p><p>People in the Caribbean and United States should be monitoring the progress of these systems closely over the next few days, just in case it survives the marginal conditions.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-12 114229-1786556557910.png">The next storm on the list in the Atlantic this season is Dolly.

<p>After a damaging week of severe thunderstorms and flooding, the pattern of destructive weather continues for the Midwest. Rounds of storms are likely in the same spots through Saturday. This will lead to a risk of flooding across these areas.</p><h1>FLOODING</h1><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2087637748538658920" src="https://x.com/WeatherNation/status/2087637748538658920"></div><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-15 044318-1786790610952.png">A stationary boundary draped across the same areas, stretching from Iowa to West Virginia, has led to more flooding issues.Since it will not take much more heavy rain to cause more flooding issues, please heed any flood warnings for your area. Some area rivers have never seen levels this high. The additional rainfall is expected to prolong some flooding but not add to it. <img src="https://media.weathernationtv.com/app/uploads/2026/08/1-1786760477821.png"></p><p>Storms will steer clockwise around that high through the weekend. A Moderate Risk (above) of flooding has been introduced over parts of Indiana and West Virginia for Saturday and Sunday. An additional 3-6 inches will be possible over these waterlogged areas.<img src="https://media.weathernationtv.com/app/uploads/2026/08/1-1786760544741.png"></p><p></p><h1>SEVERE</h1><p></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-15 044401-1786790649418.png">Saturday will once again highlight Eastern Colorado and the Panhandle of Nebraska for strong storm development. The center of low pressure will finally start to move east, but we still expect strong storms near the low and along the warm front. Once again, Indian to North Carolina will see strong storms. The lingering cold front will pop up additional activity through Illinois, Iowa and Missouri.</p><video src="https://media.weathernationtv.com/app/uploads/2026/08/2026-08-15 04-44-38-1786790706040.mp4" controls="true" width="100%"></video><p>Make sure to stay tuned to WeatherNation for the latest on this forecast!</p>

Totality will only cover a small portion of the globe, however, while many others will see a partial solar eclipse.<br><br>A solar eclipse happens when the moon moves between the sun and earth, casting a shadow on the Earth's surface. There's a small "hard shadow" where the total solar eclipse occurs, where the sun is completely obscured by the moon, leaving only the outer ring, or corona, of the sun visible. The larger "soft shadow" covers a larger portion of the globe, but only a section of the sun will be obscured. Even though both are eclipses, the experience in the path of totality is completely different than in the partial zone. Totality ushers in darkness and massive changes, including temperature drops, changes in animal behavior, and more. If you have the chance to see a total solar eclipse, it is highly recommended you take advantage of the opportunity.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-07 124538-1786128790332.png"></p><h1>Path of Totality</h1><p>People in parts of Greenland, Iceland, Spain, and an incredibly small piece of Portugal, will be able to experience totality if skies are clear enough.

Only a small sliver of the sun will be obscured for many, with about a fifth of the sun obscured in northern New England, mostly in Maine. All of Alaska (expect the far western Aleutians) will experience a partial solar eclipse as well.

<p><strong>HIGH PLAINS</strong> - Tuesday proved to be an incredibly active day across the Central and High Plains. Storms in these parts had updrafts that exceeded 100 mph! Therefore, we were seeing hailstones that were 4.5" in diameter! That's about the size of a grapefruit. Once again, strong storms fired up Wednesday afternoon, bringing large hail and damaging winds. Wind gusts reached over 70 mph for portions of Iowa.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/plains winds-1786581631787.png"></p><h2>Overnight</h2><p>The severe threat will continue through Thursday morning.

<p>After the solar eclipse happens Wednesday afternoon grab some coffee, because one of the best meteor showers of the year peaks late Wednesday night into Thursday morning!<br><br>The Perseid meteor shower is often considered the best of the year for it's high rate of meteors and warm overnight temperatures, especially compared with the Geminids which peak in December. This year's show could be particularly dazzling since the moon will be new, leaving skies perfectly dark away from light pollution. The meteors are named after the constellation from which the appear to emanate, which is Perseus, located in the east-northeast this time of year.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-08 092352-1786203103738.png">While clouds are forgotten about most days that don't involve the beach, they become your worst enemy when it comes to viewing the cosmos at night. </p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-12 081926-1786544372075.png">Do you need to bring binoculars for a meteor shower? No! Try to take in as much of the sky as possible at once, which will let you see as many meteors as possible. Find a dark place away from city lights, give your eyes about 20 minutes to adjust, and wait for the show! Meteors can come in bursts so don't be discouraged if you don't see many initially, or if the rates slow down. Bring some lawn chairs or a blanket, snacks, and some beverages.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-08 093010-1786203095588.png"></p>

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!
