The Pineapple Express is sending waves of heavy snow into Wyoming, Idaho, and Montana. There are two additional storm systems through 2/9. Rich atmospheric moisture (from near Hawaii) gets picked up by the jet stream and then entrained into storm systems before being delivered to the West Coast.<img src="https://media.weathernationtv.com/app/uploads/2025/02/Tomer humidity AR 222025-1738527110672.jpg">Watch the timing:<video src="https://media.weathernationtv.com/app/uploads/2025/02/TOMER WY ID MT FUTURECAST 2-1738641116894.mp4" controls="true" width="100%"></video>Feet of total accumulation is likely across the mountains of Idaho, Wyoming, and Montana.Here are a few highlights:<ul><li>Sun Valley, ID: 18-24 inches.</li><li>Jackson Hole, WY: 6-9 inches.</li><li>Grand Targhee, WY: 6-9 inches.</li><li>Big Sky, MT: 3-6 inches.</li><li>Bridger Bowl, MT: 3-6 inches.</li><li>Wind River Range, WY: 10-20 inches.</li><li>Discovery, MT: 9-12 inches.</li><li>Brundage, ID: 12-24 inches.</li></ul><img src="https://media.weathernationtv.com/app/uploads/2025/02/TOMER ID MT WY SNOW FORECAST 2-1738641130606.jpg">

The record-setting trend began on Sunday, as many locations across Texas and the Southwest saw their daily highs surpass record levels. On Monday, further records fell across much of the country. Earlier in the day, records began to fall across the Ohio River Valley. Cincinnati saw a record fall for the day that stood 142 years!<img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-03 191817-1738635503925.png">Texas once again got in on the act:<img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-03 192007-1738635619064.png">One of the more notable records came out of Las Vegas, where the city felt its 2nd earliest 80° day on record.<img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-03 192032-1738635670899.png">Record-high temperatures will remain widespread through the rest of the week.

The West Coast has gotten off to a hectic start this week! The same energy that is prompting the heavy rain and snow will move into the Plains later this week. What happens from there? It's still a little murky...Related: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/atmospheric-river-makes-an-appearance-this-weekend">Pineapple Express Roars Onshore</a>Starting with what we know, temperatures will be warm for many of us. That already has us thinking in a different direction than we normally are at the beginning of February. Could we have enough energy to work with from a severe aspect? The Storm Prediction Center--which tries to sniff out severe weather setups a few days in advance--even mentioned Sunday morning:<blockquote>"given what appears to be a pattern of inherently low predictability, delineating areas of severe-weather potential would appear imprudent."</blockquote><img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-02 102428-1738517169501.jpg">These impulses are fairly weak. Meaning that might not have enough kick to start robust thunderstorm activity. It also means that they could time up with better ingredients a little easier - models don't handle weak waves quite as well as strong ones. This falls under a check back forecast.<img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-02 102527-1738517391075.jpg">Perhaps the more interesting signal comes when the moisture moves far enough north to find freezing temperatures. Warmer air is forecasted to get pulled over the top of sub-freezing air at the surface. Depending on the depth of the colder air at the surface, freezing rain and/or sleet could be noted. <img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-03 191029-1738635040741.png">Here's how the latest model run has the late week playing out:<video src="https://media.weathernationtv.com/app/uploads/2025/02/centralcluster-1738635249963.mp4" controls="true" width="100%"></video>Confidence in wintry impacts is beginning to increase.

A moderate to extreme intensity surge of atmospheric river (AR) moisture has been unleashing heavy precipitation in California. Another AR will approach the region toward the middle of the week with lower snow levels and widespread rainfall. What is an AR surge? It's extra moisture that is funneled into storm systems often making them wetter. AR events can generate flash flooding, mudslides, and feet of high mountain snowfall accumulation. The atmospheric river is sometimes referred to as the 'Pineapple Express' as it brings air from near the tropics (Hawaii) into the mid-latitudes.<img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-03 190059-1738634469618.png">Rainfall totals have really been adding up.

Flooding Concerns and Heavy Sierra Snow in California Through Tuesday

A pattern change for the West has arrived! Last weekend, moisture moved in from Hawaii courtesy of an atmospheric river aka the Pineapple Express. On top of the moisture, cold weather has filtered into the Pacific Northwest. It's been cold enough that the snow levels have been dropping down to sea level at times!<img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-03 185458-1738634102815.png">The question is, how much will add up? So far, in the cities of Seattle and Portland, not enough to cause problems. But certainly, some grassy, elevated surfaces could pick up a coating to 2 inches over the next few days.The heaviest snow will fall just to the south, with better dynamics in play. Some places could be measuring the snow in yardsticks by Wednesday!<img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-03 185604-1738634168904.png"><video src="https://media.weathernationtv.com/app/uploads/2025/02/nwsnow-1738634308280.mp4" controls="true" width="100%"></video>Some higher elevations can see upwards of 3 plus feet of snow!

Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

A pair of low-pressure systems will keep the country's northern tier under the threat of snow, wind, and cold temperatures. Areas across the Upper Midwest and Northern New England are expecting light to moderate snow, though some models have been trending toward a few areas of heavy snow and the potential of freezing rain for the windy city.<h2>Alerts and Timing</h2>Snow reports are coming in nearly 6" for spots in northeastern Minnesota. <img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-02 100930-1738516182223.jpg">Winter alerts have been issued around western Lake Superior through Sunday for heavy snow and gusty winds. Issues across Minnesota and Wisconsin will remain in place through midday Sunday, and South Dakota's winter Weather Advisory is for the second system that will bring impacts later today.<img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-02 100809-1738516104119.jpg">Snow will come in two waves - along the warm front and with a trailing low-pressure system within a stationary boundary. Areas around the Great Lakes will see snow continue into Sunday morning, where it will gradually clear Michigan by midday. The warm front snow will then track across New York and New England Sunday afternoon and evening.<video src="https://media.weathernationtv.com/app/uploads/2025/02/Baron 2-1738467113199.mp4" controls="true" width="100%"></video><h3>Round 1:</h3><img src="https://media.weathernationtv.com/app/uploads/2025/02/Web 4-1738495816476.png"><h3>Round 2:</h3>New England will be hit with snow by Sunday evening and they will brace for round two into Monday.<img src="https://media.weathernationtv.com/app/uploads/2025/02/Screenshot 2025-02-01 111148-1738433608386.png">Snow in New York and New England is expected to be lighter, for most, but heavier in the mountains and in northern Maine. Areas east of Lake Ontario into the mountains of northern New York and New England could see 3-6 inches, while areas in northern Maine could surpass a foot.

Several days of heavy rain is starting to catch up in Central Texas as many local rivers and creeks are nearing flood stage. The Llano River is at Major Flood stage and as of the latest reports from local officials residents within a quarter mile of the Llano River in the city of Llano were urged to evacuate early Tuesday.

The rushing waters of the Llano river has unfortunately allowed a section of the 2900 bridge in Kingsland, Texas, to collapse sending chunks of the bridge down the Llano River, according to local reports.  Water rescues are ongoing near Kingsland and also farther west in Segovia, Texas where Flash Flood Emergencies are in effect.

The Llano River is located about 75 miles NW of Austin. The National Weather Service in Austin has reported more than 10 inches of rain that has fallen in the last 30 hours prompting the Llano River to rise to it's second highest crest on record.

Rain will continue to fall over the area today-tonight so rivers will continue to rise.  Rain will taper off by tomorrow for some areas but an additional 2-4" can still be expected in isolated locations along and west of I-35 through Wednesday.
