Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Wed Oct 01 2025 Valid 12Z Wed Oct 01 2025 - 12Z Fri Oct 03 2025 ...Imelda accelerating eastward out to sea; swells, high surf, and dangerous rip currents continue along much of the East Coast the next several days... ...Cool and unsettled weather persists across portions of the Great Basin and Pacific Northwest... ...Unseasonably hot temperatures continue for much of the Plains and Midwest through the remainder of the week... As expected, Imelda has made its turn to the east-northeast in the southwest Atlantic Ocean and is now accelerating farther out to sea. In its wake, strong high pressure will descend southward from Canada and settle over the Northeast and Mid-Atlantic by the end of the week. This bubble of high pressure will lead to mainly dry weather and much more fall-like temperatures for most of the eastern U.S. heading into the weekend. However, a prolonged stretch of strong, easterly, onshore flow on the southern periphery of the dome of high pressure combined with the increased wave action generated by both Imelda and Humberto will also lead to swells, high surf, and dangerous rip currents along much of the East Coast the next several days. Additionally, the moist onshore flow will also make an exception to the mainly dry weather across the Southeast U.S. as several rounds of showers and thunderstorms are likely for coastal areas of the Carolinas, Georgia, and especially the east coast of Florida. In fact, the repeating nature of this activity could lead to isolated flash flooding concerns through the rest of the week and for much of the weekend as well. Unsettled and unseasonably cool weather will continue for parts of the Pacific Northwest, Great Basin, and Intermountain West the next few days as persistent upper-level troughing and a couple frontal systems pass through the region. Moist Pacific flow combined with a series of surface fronts and upper-level disturbances will bring periodic waves of showers and thunderstorms through the end of the week. Even a little bit of snow could mix in with the rain in the highest elevations. In the lower elevations, some of the more intense showers and thunderstorms could contain periods of heavier rainfall. While the overall threat remains low, localized flash flooding still can't be ruled out across parts of the Great Basin, Sierras, northern Rockies, and the Olympic Peninsula. The increased presence of clouds and precipitation associated with the passing disturbances and persistent upper-level troughing will result in high temperatures roughly 5 to 15 degrees below normal across much of the western U.S. through Friday and leading into the weekend. A large and strengthening upper-level ridge over the central U.S. will continue to produce an extended period of unseasonably hot weather across the Plains and Midwest through the end of the week. The hottest weather relative to climatology will be confined to the northern Plains and Upper Midwest, where high temperatures will soar to between 10 and 20 degrees above normal today and Thursday, to between 20 and 30 degrees above normal on Friday. In fact, several places have the potential to tie or break high temperature records on Friday. One such location is Minneapolis, MN with a forecast high of 90 degrees set to tie the daily record of 90F set back in 1997. Safe to say, it will be feeling much more summer-like than fall-like as we roll the calendar into October. Miller Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
