088 FXUS01 KWBC 190800 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 359 AM EDT Sun Apr 19 2026 Valid 12Z Sun Apr 19 2026 - 12Z Tue Apr 21 2026 ...Lingering showers for the Northeast Sunday with a light wintry mix possible for interior/higher elevation locations... ...Dry and gusty conditions will lead to a fire weather threat over portions of the southern High Plains Sunday... ...Increasing precipitation chances heading into the work week along the West Coast ahead of an approaching Pacific system... Showers and thunderstorms will continue into the early morning hours through the Northeast as a cold front clears the coast. A wintry mix is expected for portions of the Interior Northeast, particularly for higher elevations, where some light snow accumulations will be possible. Precipitation will linger longest through portions of the Interior Northeast and the Appalachians as a secondary cold front will bring another round of rain/snow showers later Sunday night and into early Monday. Thereafter, much of the central and eastern U.S. will be dry to start the work week. The exception will be along the lingering frontal boundary through South Florida as well as into portions of Texas. An upper-level shortwave will lead to increased thunderstorm coverage on Monday across south and central Texas, where some isolated flash flooding is possible. Gusty winds and very dry conditions will bring a threat of fire weather today for portions of the southern High Plains, particularly for northeast New Mexico, southeast Colorado, southwestern Kansas, and the Oklahoma/Texas Panhandles where the Storm Prediction Center has outlined a Critical Risk (level 2/3). An approaching deep upper-level low and frontal system over the Pacific will bring increasing precipitation chances to the West Coast over the next couple of days. Some light showers will be possible today for northern California before more widespread, moderate to locally heavy rainfall moves in to northern/central California on Monday. Coverage will further expand Tuesday including into the Pacific Northwest, southern California, and portions of the Great Basin. Isolated flooding will be possible along the northern/central coastal ranges of California as well as the Sierra. Heavy high elevation snow is also expected for the Sierra on Tuesday. Chillier, below average temperatures have arrived for much of the eastern half of the country following a cold front passage this weekend. Forecast highs the next couple of days will be in the 40s and 50s across the Midwest and Northeast, with 60s and some 70s across the southern tier from Texas into the Southeast and southern portions of the Mid-Atlantic. Meanwhile, a strengthening upper-level ridge ahead of the approaching Pacific system will bring above to well above average conditions across the western U.S. Highs across the Interior West will be into the 60s, 70s, and possibly even the low 80s, and the Desert Southwest will see highs into the 90s. These warmer temperatures will also spread into portions of the northern/central Plains by Monday as highs soar into the 70s and 80s after a chilly weekend. Temperatures along the West Coast will vary around average as the Pacific system approaches, with highs in the 60s and 70s.
