<h1>WHAT TO EXPECT</h1><p>That first dynamic system moved through the Rockies Saturday before the next front moved onshore late Saturday into Sunday. That next wave will push into the Rockies to start the week, with another low moving in toward the mid-week timeframe.</p><video src="https://media.weathernationtv.com/app/uploads/2026/11/fsaaaaaassssss-1794363172414.mp4" controls="true" width="100%"></video><p></p><h1><strong>SHORT RANGE FORECAST</strong></h1><p>The first system brought snow and rain to parts of the Four Corners and Wyoming on Saturday night, with snow and rain tapering off Sunday morning as the low dives into Texas. The next front moved into the Pacific Northwest Saturday night, slowly sliding down the west coast and across the interior through Tuesday. This next system will bring much colder air, with temperatures in some areas dropping more than 10 degrees. This means more rain will turn to snow for lower elevations.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/11/Screenshot 2026-11-15 080124-1794754901852.png"></p><h1>WINTER ALERTS</h1><p>The highest totals are expected in the higher elevations.

<p>For the rest of the weekend, heavy rain and storms will move across Texas. Isolated severe storms are in the forecast into early Monday morning. The big story from this setup will be all the heavy rain for Texas, and this includes cities like Dallas and Houston!</p><h1>SEVERE THREAT</h1><p>Sunday, a Marginal risk is in effect for parts of South Texas from the Rio Grande up to Interstate-10. The primary threat will likely be damaging winds, but a few isolated tornadoes can't be ruled out.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/11/Screenshot 2026-11-15 074045-1794753662077.png"></p><p>There's so much wind energy that Wind Advisories were issued along the Texas Coast for elevated breezes reaching 40 mph. All of that energy could organize a few storms, capable of producing a tornado or two this afternoon. </p><p></p><video src="https://media.weathernationtv.com/app/uploads/2026/11/2026-11-15 07-44-56-1794753926824.mp4" controls="true" width="100%"></video><p>The broader concern will be the rainfall amounts. Efficient storms could produce an inch or two of rain, but if a storm were to lock onto one part of the coast, those totals could rapidly increase. The Weather Prediction Center is monitoring the area with a SLIGHT risk of excessive rainfall</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/11/Screenshot 2026-11-15 074413-1794753868870.png"></p>

<p>Millions of Americans are getting a chilly reminder that winter is right around the corner as a surge of cold air spreads across the central and eastern United States this weekend.<span style="color: rgb(0, 0, 0)">&nbsp;</span></p><p>After weeks of unusually mild fall weather, temperatures are taking a sharp turn; some cities saw their first freeze of the season Saturday morning.<span style="color: rgb(0, 0, 0)">&nbsp;</span></p><h1>Saturday Observed Low Temperatures</h1><p><img src="https://media.weathernationtv.com/app/uploads/2026/11/Screenshot 2026-11-14 082450-1794669901832.png"></p><p>The dramatic cooldown is being driven by a southward dip in the jet stream, allowing colder Canadian air to spill into the Plains, Midwest and Southeast. Temperatures in some areas could fall 10 to 15 degrees below seasonal averages.<span style="color: rgb(0, 0, 0)">&nbsp;</span></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/11/Screenshot 2026-11-14 082611-1794669984519.png"></p><p>The Midwest will experience some of the coldest conditions, with overnight temperatures dropping into the 20s across portions of Nebraska, Iowa, Missouri and surrounding states. Cities including Omaha and Kansas City could see their first significant freeze following an extended stretch of warmer-than-normal weather.<span style="color: rgb(0, 0, 0)">&nbsp;</span></p><p>Farther east, the cold air will reach communities around the Great Lakes, including Chicago and Detroit, where residents can expect a noticeable change from the mild temperatures experienced earlier this month.<span style="color: rgb(0, 0, 0)">&nbsp;</span></p><p>The Southeast won’t escape the chill. Temperatures across Tennessee, Alabama, Georgia and the Carolinas will tumble into the 30s and 40s, with some locations facing the possibility of frost or freezing conditions.<span style="color: rgb(0, 0, 0)">&nbsp;</span>Even the Sunshine State will get a taste of colder weather. Morning temperatures across Central Florida, including Orlando and Tampa, could dip into the 40s, while parts of North Florida may experience readings in the upper 30s. South Florida will remain warmer, although overnight lows could fall into the 50s.<span style="color: rgb(0, 0, 0)">&nbsp;</span></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/11/Screenshot 2026-11-15 071646-1794752227011.png"></p><p>These cooler temperatures will linger around many of these same areas for a few days. A stubborn area of high pressure will struggle to move much over the next few days. By Tuesday morning, many of us who aren't used to a crisp morning might be by then. </p><p>The arrival of freezing temperatures is particularly notable after an unusually warm autumn delayed the seasonal cooldown across portions of the country.<span style="color: rgb(0, 0, 0)">&nbsp;</span></p>

<p>There are only a few weeks left in the Hurricane Season and it looks like it will be quiet end to the season. There is no tropical activity in either the Atlantic or the Eastern Pacific basins. </p><h1><strong>ATLANTIC BASIN</strong></h1><p>Not much is happening in the Atlantic Basin and that will continue for at least the next 7 days.<img src="https://media.weathernationtv.com/app/uploads/2026/11/PIC 4-1794617871577.png"></p><h1>Eastern Pacific Basin</h1><p><img src="https://media.weathernationtv.com/app/uploads/2026/11/PIC 5-1794618538087.png">Although tropical activity typically decreases as fall progresses, the Atlantic hurricane season officially continues through November 30. The Eastern Pacific hurricane season also runs through November 30. For now, neither disturbance has developed into a tropical cyclone, but the Pacific system has the greater potential for organization this week.</p><p>WeatherNation will continue monitoring both areas of interest and provide updates as new information becomes available from the National Hurricane Center.</p>

<p>Heavy snow is piling up across portions of the Northeast, especially in New York State where over a foot of snow has accumulated! Snow will continue through Friday morning before tapering off. Lake effect snow will continue around the Great Lakes while the southern Appalachians see a northwest flow snow event into Saturday morning.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/11/Screenshot 2026-11-13 063936-1794577352746.png"></p><h2>Forecast Timing</h2><p>Snow will taper off through Friday morning in the Poconos, possibly lingering into the early afternoon. As cold NW flow kicks in, lake effect snow and upslope snow (Appalachians) will kick in, lasting into the weekend for some.</p><video src="https://media.weathernationtv.com/app/uploads/2026/11/FORECAST2-1794602135827.mp4" controls="true" width="100%"></video><h2>Snow Totals</h2><p>Additional snow totals could top 3-4 inches in a few areas thanks to lake effect that continues through Saturday, but overall an inch or two will fall still.

<p>We've got a party getting started in the midweek with a strong low building in and heading east. It'll bring some heavy rain and maybe even snow to the Northeast; more on that <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/east-coast-snow-what-we-know-about-the-late-week-system">here</a>.

They're warm enough, but the setup itself isn't going to lend itself much to a widespread lake effect event. It'll likely stay more isolated.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/11/Screenshot 2026-11-10 045743-1794312721662.png"></p><p>Stay tuned to the forecast here on WeatherNation.
