It happens every year. One day, the air is cool and crisp, and it feels like fall. The next, it's summer again.

Fall shift in weather as rain, snow and strong winds sweep the Western US 🌧️ 🌨️ WESTERN SWEEP: The next shift in weather has arrived this fall as rain, snow, and strong winds barrel down through portions of the Western U. S., with high-elevation areas experiencing winter weather while others experience heavy precipitation, triggering a widespread flood threat for the Four Corners region. The Southwest is experiencing rare impacts from the remnants of Rachel, which made landfall in Mexico just south of the U. S. early on Sunday. The impacts on Southern California and the Southwest are significant, with the FOX Forecast Center noting that months of rainfall fell in just a few hours throughout the weekend. WHAT'S THE DIFFERENCE BETWEEN A HURRICANE MAKING A DIRECT HIT AND LANDFALL? Rachel — which weakened from a tropical storm Saturday night, approached northern Baja California during the day Saturday, and moved onshore late Saturday night.

After the remnants of Hurricane Isaias depart southern Ontario on Sunday, perhaps the final surge of summer-like warmth this year will make a brief appearance this week. DON'T MISS: Canada's Winter Sneak Peek: El Niño puts record warmth in playThe week will start with unseasonably warm, July-like conditions, possibily the final time this year for southern Ontario. But the pattern brings the energy for thunderstorms Monday night and Tuesday. Following the storms, an upper-level low will drag in much colder air, leading to a significant temperature drop in time for next weekend. Temperatures to soar early this week, with thunderstorm riskFor those heading out early on Thanksgiving Monday, expect reduced visibility on the roads with patchy fog, thanks to residual, departing moisture from former Hurricane Isaias. Through the day, the fog burns off, allowing for a mix of sun and cloud to enjoy. Mild temperatures of around 20°C can be expected--at least five degrees above seasonal. However, conditions will change Monday overnight into early Tuesday, when a fairly potent low will spreads showers and thunderstorms across southern Ontario.

High-tide flooding, enhanced by Tropical Storm Rachel looming hundreds of miles offshore, overwhelmed streets and structures in Newport Beach, California, and surrounding areas. And although Rachel is expected to weaken further prior to a possible landfall, parts of Southern California to the south of Newport Beach were under a rare tropical storm watch.

The northeastern Pacific Ocean just cracked the top spot for its most active hurricane season ever recorded. Almost every hurricane that’s formed this year intensified into a major Category 3 storm or stronger, including three scale-topping Category 5 storms. A record-setting El Niño is largely responsible for this hyperactive hurricane season. DON’T MISS: ‘ACE’ is the best way to measure a hurricane season’s ferocityA historic season with more room for growthAs of Oct. 11, we’ve seen 21 storms form throughout the eastern and central parts of the Pacific basin this season, which have caused major damage from Hawaii to Mexico. Beyond counting the raw number of storms, forecasters measure the true intensity of a hurricane season using Accumulated Cyclone Energy (ACE). This metric accounts for the intensity and longevity of each storm. A stronger, longer-lived storm will generate a much higher ACE value than one that’s weak and brief. Content continues belowData from Colorado State University reflects that the northeastern Pacific’s ACE value hit 318.8 as of 5:00 p.m. EDT on Sunday. This beats the previous all-time record of 318.1 observed during the robust 2018 hurricane season.

National Hurricane Center (NHC) note there’s some uncertainty surrounding exactly when or if the storm will officially come ashore. Big questions remain over landfallSerious uncertainty about whether this hurricane will actually make landfall on Sunday or Monday.

Spooky nebulas and the blinking Demon Star haunt October’s skyThe nebula of a witch and her broom, a ghoulish demon star and a celestial jack-o'-lantern? All of these haunting sights are in the sky now, just in time for Halloween. Here's your guide to some spooky stargazing and space facts for the month of October. Using the constellations Cassiopeia and Andromeda, locate Perseus. You can find Algol by using the star Almach as a guide.(NASA/Stellarium)The Ghoul or Demon StarAlgol, a name for a star scary enough on its own. But knowing it also goes by the "Demon Star" or "The Ghoul"? That's chilling. Early astronomers gave this star its name as a nod to the mythic Medusa, a snake-haired monster whose gaze turned anyone who looked at her into stone. Algol is actually a triple-star system — with two of the three stars orbiting one another. That's how it gets its signature "blinking" feature, appearing brighter and dimmer at different times.(MORE: El Niño is playing trick-or-treat with your Halloween forecast)Get More of Our News on GoogleSet The Weather Company as a 'Preferred Source' to get quicker access to the news you value.

The hidden Antarctic lake no one has ever seen: Lake VostokThere's a lake on Earth and no one has ever even seen it. It's the 16th largest on our planet, about 160 miles long, 30 miles wide, 3,000 feet deep and trapped under two and a half miles of ice in East Antarctica. Lake Vostok is the largest known subglacial lake in Antarctica, and it has been hidden beneath the ice for at least 15 million years. It's an ancient environment and one of the most isolated places on Earth that remains very much a mystery to us today.(MORE: A record-breaking T. rex, an Antarctic fossil, and the climate clues in dinosaur bones)Since Vostok's discovery, more than 350 smaller lakes have been located in Antarctica.

While Canadians enjoy the turkey, stuffing, gravy and all the fixings in October, Americans south of the border still have more than a month to wait before they dive in. Why is it they aren’t held at the same time? I asked historian and host of the Canadian History Ehx podcast, Craig Baird. “I think it does come down to the harvest with them and with it being later. Obviously, southern states, you’re not going to have winter like we do. So, in Canada, because our harvest is much earlier and we have a much shorter growing season, it really comes down to us having Thanksgiving much earlier because it is a celebration of the harvest," said Baird. "Even the First Nations, before the Europeans ever arrived, were celebrating a form of Thanksgiving that was also the same thing, giving thanks for the end of the summer, the autumn and then looking at the coming winter.” Thanksgiving dinner.
