377 FXUS01 KWBC 091955 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 254 PM EST Mon Feb 09 2026 Valid 00Z Tue Feb 10 2026 - 00Z Thu Feb 12 2026 ...A frontal system will bring precipitation to California and the Central Intermountain West beginning Tuesday morning and will continue through late this week... ...A clipper system is expected to bring snow and wintry precipitation to the Great Lakes, before moving into the Northeast mid-week... ...Above-average temperatures are set to continue for much of the western and central United States, with conditions in the east also moderating.... An upper-level trough, currently located in the Pacific, is forecast to move into California and the Central Great Basin/Intermountain West on Tuesday. Upper- to mid-level support will allow for a surface frontal system to persist, while another mid-latitude cyclone begins to move in from the Pacific on Wednesday. Precipitation in California and parts of the Intermountain West is set to begin on Tuesday morning in the form of rain on the lower elevation/coastal regions, and snow/wintry mix on the upslope regions and regions of higher elevation. Precipitation will then linger through the middle of the week, as the aforementioned mid-latitude cyclone arrives on Wednesday. This system will bring in an influx of moisture, along with favorable low-level flow onshore, and will result in locally heavy precipitation, particularly in the upslope regions of California on Wednesday. A clipper system will continue moving along the U.S./Canadian border, bringing some wintry precipitation to portions of the Upper Great Lakes today, with light snow and freezing rain possible. The system will continue eastward on Tuesday bringing more moderate snow to portions of Upstate New York and central New England. Further south, showers and thunderstorms are expected ahead of a cold front stretching from the central Appalachians through the Southwest on Tuesday, continuing into Wednesday. Precipitation associated with this front is expected from the Tennessee Valley/Mid-South through as far west as portions of the Southwest. Above-average temperatures are set to continue through early this week for the central and western United States. Temperatures today in the Central Plains could reach as high as 80 degrees, particularly in Kansas and Nebraska. The previously mentioned cold front in the Central Plains will then move through the Central and Southern Plains on Tuesday. This will bring down temperatures slightly, but they are expected to generally remain unseasonably high. With the passage of the front, gusty winds are expected to commence thereafter. Low humidity and strong downsloping winds will bring the risk of fire weather, which has prompted the Storm Prediction Center to issue a Critical Risk of Fire Weather (level 2/3) for parts of the Central and Southern High Plains. After having experienced extremely cold temperatures for the past few weeks, the eastern U.S. will finally see a widespread reprieve from the extreme cold on Tuesday. Above average temperatures are forecast to span from the Southeast through the northern Mid-Atlantic, with temperatures up in the 40s and 50s in the Mid-Atlantic, and in the 60s and 70s in the Southeast. Unfortunately for the Mid-Atlantic and Northeast, colder temperatures are then expected to return to end the week, albeit much less extreme.
