Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 352 PM EDT Sat Nov 05 2022 Valid 00Z Sun Nov 06 2022 - 00Z Tue Nov 08 2022 ...Atmospheric River will continue to bring widespread rain and high elevation snow to the Pacific Northwest today... ...Strong winds and wintry precipitation across the Northwestern U.S. with a cold front passage this weekend... ...Moderate to Heavy mountain snow possible in the Cascades and northern/central Rockies today and Sunday and Sierra Nevada Monday... ...Above normal temperatures in the eastern U.S. and below normal temperatures in the western U.S. through early next week... The potent storm system responsible for the significant severe weather outbreak last evening continues its eastward progression, as an associated cold front sweeps through the Midwest and Mississippi Valley today, producing showers and thunderstorms. Gusty winds will be possible across the Great Lakes region as the system intensifies, with High Wind Warnings and Wind Advisories being issued for much of the region through this evening. On the backside of the cold front, cooler and drier air will filter in across the northern and central Plains, while areas further south near the Gulf Coast will only experience a brief reprieve from the above-average temperatures, as the aforementioned front stalls and pushes north, bringing a return of onshore flow for much of the region. Further east, the cold front will begin to stall across the Ohio Valley and become more diffuse, with rain chances quickly decreasing late tomorrow into Monday. In addition to the relatively dry conditions expected over the next several days for the East Coast, well-above average temperatures will persist under the influence of an expansive high-pressure system centered offshore the region. Temperatures in the mid-to-upper 70s are forecast to stick around through the early work week before the next cold front sweeps through the region, bringing in much drier air albeit with highs continuing to remain steady in the 70s. In the West, a strong atmospheric river event continues to dump widespread precipitation across the Pacific Northwest, where several inches of rain have already fallen. An additional 1-2" of rain will be possible before a cold front pushes southeast across the region today, shifting the atmospheric river south towards northern California. Rain and mountain snow will continue across the region as the front moves through, but precipitation rates will be less than in previous days. Any additional rain could exacerbate flooding concerns in areas that have already seen several inches of rainfall this week, leading to Flood Watches being issued in parts of Washington through the afternoon. In addition to the low-elevation rainfall, moderate to heavy mountain snow is possible in the higher elevations of the Cascades and Sierra Nevada Mountains and northern and central Rocky Mountains. As a result, Winter Storm Warnings and Winter Weather Advisories are in effect. Strong winds will also impact much of the Intermountain West and northern Plains over the next 24 hours due to tightening pressure gradient as a low-pressure system intensifies over southern Canada, with widespread High Wind Warnings and Wind Advisories in effect.
