<p>After becoming a hurricane Friday, <strong>Vance</strong> has weakened to a tropical storm, but it continues to trudge parallel to the Mexican coastline, where the impacts are expected to be greatest. Its slow movement will mean long-lasting coastal wave action and erosion potential. The good news is, it should weaken as it enters an unfavorable environment early this week. A landfall in Mexico late this week is possible.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-27 192231-1793150555352.png">Tropical Storm <strong>Olana</strong> formed in the Central Pacific Ocean this week but has since become post-tropical. This storm is west of the Hawaiian Islands. Hawaii can see multiple inches of rain from the moisture from Olana through Saturday.

<p>Hopefully the costume's picked out by now, the candy receptacle is made or purchased, and physical conditioning is in peak form! It's the week of Halloween which has all of the spooky lovers in a good mood. The only thing that might get in the way is Mother Nature.</p><h1>TREATS</h1><p>We'll start with the easy ones since forecasting multiple days in advance can be a little frightening to meteorologists. But signals can be a little clearer about who has it going well, weather-wise. Focusing on Fri-Sun, it's hard to complain about Denver's setup. A building ridge should keep things eerily quiet on the weather front this weekend.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-26 081108-1793023905794.png">Roughly, a line from the Front Range into the High Plains should be good to go if the timing/placement of this ridge is nailed down. That means we just have to prepare for the festivities, with some help from the Red Cross</p><h1><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-26 080023-1793024061010.png">TRICKS</h1><p>This is where things get...tricky. Right now, the two different areas that are of some concern are the Southern Plains and the West. Another strong trough will pour onshore late in the week, keeping things out west pretty active. Ahead of that trough, plenty of moisture will get pulled north out of the Gulf, which could help fuel stronger storms, depending on how things come together.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-26 082100-1793024562701.png">Along and downstream of that feature rippling through the Midwest and eventually the Mid-Atlantic might want to watch the timing on things, just to be sure an umbrella doesn't need to become a part of the costume too. It's too soon to know if it'll be a washout that affects plans all day or splash-n-dash storms that pick on a particular timeframe.</p><h1>FALL BACK</h1><p>Also, remember to set the clocks back an hour going into Sunday. Otherwise, you'll be waking up an hour early when you could have been sleeping off the candy coma instead. Might be a good weekend to replace the batteries in the smoke detectors and weather radios, too!</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-26 080329-1793024897195.png">Or maybe take the day to ease into a new way of life, with sunsets closer to 5:00. Although latitude has something to do with it, location within your timezone has a lot to say too.</p><p></p>

HALLOWEEN 2026: Is the weather a Trick or a Treat?

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

<p>Heading towards the Halloween weekend, the southwest is expecting another push of moisture as a strengthening low moves into the region.</p><p>The Weather Prediction Center (WPC) has already issued an outlook for Friday. Cities like Flagstaff, AZ, and Phoenix, AZ are under a <strong>Slight</strong> risk for flooding.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-27 160831-1793138915709.png">An isolated, <strong>Marginal</strong>, threat for flooding is in effect across Southern California, Nevada, and Arizona for Saturday.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-27 160848-1793138934526.png">This could mean a soggy and cold Halloween for Trick or Treaters on Saturday. We are still several days away, but some of the longer-range forecast models are bringing in widespread precipitation for Halloween.</p><video src="https://media.weathernationtv.com/app/uploads/2026/10/1026-1793036950479.mp4" controls="true" width="100%"></video><p>There looks to also be some snowfall accumulation for the higher elevations.

Southwest Gets More Active By Halloween Weekend

<p>The cooler weather is finding places to go finally! It's that time of year to look ahead to any chance of flakes we get! This one might get more hopes up of turning Mount Rushmore into Mount Slushmore.</p><p>A cold front has dropped temperatures from record territory into an area where we could get back to freezing. We won't stay below freezing all day, which starts to complicate matters. Moisture has been streaming in behind this front, pouring out of the Four Corners region. As the core of this upper-level low moves in and drops temperatures that much more, we could change some rain over to snow.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-25 185415-1792976060412.png"></p><p>However, there are a few issues with what some models are projecting (2+" of snow).</p><ol><li><p>Temperatures won't get all the way or well below freezing</p></li><li><p>Snowing during daylight hours is tough to accumulate. Even though the sun won't be "shining" it adds energy to the atmosphere making it harder for snow to stick while it's up.</p></li><li><p>Rain and snow falling together makes it harder for the snow to stick. Falling raindrops will either melt the snow itself, or leave puddling behind which melts falling snowflakes.</p></li></ol><p>Just because temperatures are in the vicinity of freezing, not all snowy setups are created equal. If this were a month or two later with a lower sun angle and slightly cooler temperatures, we could be cooking with gas! But alas, rain will mix with snow throughout the day, trying to accumulate on grassy, elevated surfaces. We might get lucky and pick up an inch in a spot or two, but it's going to be an uphill battle. Roads by Monday night could see a few slick spots.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-26 123650-1793039815143.png"></p>

<p>A powerful low pressure system has been moving through the Southwest since Wednesday, producing numerous flash flood events and severe weather. A tornado hit a few homes in Heber-Overgaard (Arizona) on Wednesday, causing significant damage, while hailstones larger than golf balls have been falling at times. The heavy rainfall rates have led to several significant flash flood events, like the one below, including several calls for swift water rescues.</p><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2113405036651008510" src="https://x.com/WeatherNation/status/2113405036651008510"></div><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-24 083001-1792852233932.png">Unfortunately, the San Juan River has caused damage in multiple areas, from Pagosa Springs down through northern New Mexico.

<h3>WHAT TO EXPECT</h3><p>A ridge of high pressure lingers, keeping temperatures above average across the central U.S. Temperatures across the south will run 5°-10° above average, but in the northern Plains and Midwest, 10°- 20° above average! This will make for some warm weather for any fall activities you have planned.</p><h3>NORTHERN PLAINS AND MIDWEST:</h3><p>It was another warm October afternoon on Saturday across the High Plains. A sharp cold front is dropping through the area this weekend, however. Check out the highs in the forecast through Monday. Minneapolis will only reach 49° Monday afternoon.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-25 061228-1792923161399.png"></p><p>The Central and Southern Plains won't feel as significant of impacts from this front. Temperatures will linger above average, in the 70s and 80s, through the weekend. However, there's some signal that temperatures will cool off late this week 👀</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-25 061314-1792923207632.png"></p><p>This year has been a good reminder to enjoy the cool air when it does make an appearance. As we look ahead to the last few days of October, there is high confidence that much of the country will remain above average. That looks to include and Trick or Treaters if the pattern holds up!</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-25 061339-1792923233181.png"></p>

<h1>SETUP</h1><p>The National Hurricane Center was watching the coastal low that brought many impacts to the eastern U.S.. Josephine quickly became a subtropical storm. As quickly as this storm became subtropical, it changed to Post-Tropical. Here is a look at the latest information.</p><h1>JOSEPHINE FORECAST</h1><p>Josephine is no longer being monitored by the National Hurricane Center. This storm is post-tropical, and that means it is basically a low-pressure system in the Atlantic waters. The impacts will be diminishing through Friday morning along the Atlantic Seaboard.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/PIC 5-1792702093000.png"></p><h3>FORECAST WAVE HEIGHTS</h3><p>Wave heights between 10-20 feet will be possible at times, making for dangerous conditions.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/PIC 4-1792702130751.png"></p><h1>IMPACTS</h1><p>High winds with Josephine will wear down many beaches along the eastern seaboard. What's of most concern are the beaches in North Carolina, which stick out farthest, and places like Virginia, which will have to endure days of breezy winds agitating the seas. Waves of 10-15 feet can be expected, which will help push a few feet of seawater onshore into normally dry stretches of the coast.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/PIC 4-1792702219831.png">More updates on this evolving setup will be coming up all day and night on WeatherNation.</p><h1></h1>
