####018002139#### FNUS28 KWNS 282202 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0500 PM CDT Mon Apr 28 2025 Valid 301200Z - 061200Z ...Eastern U.S.... An upper-level trough and associated surface low will translate eastward from the Great Plains on Day 3/Wednesday to the eastern Seaboard through the weekend Day 6-7/Saturday-Sunday. Widespread rainfall is expected across much of the eastern U.S. as the trough and associated cold front interact with a broad moisture plume through the weekend. In addition to rainfall, accelerating green-up should mitigate fire spread potential into early next week (Days 7-8/Sunday-Monday). ...Southwest... A short wave-trough with an associated mid-level jet will move into the Southern High Plains for Day 3/Wednesday. This will overrun a dry/well-mixed boundary layer supporting low relative humidity and gusty west winds across southeastern New Mexico into far West Texas. A subtle mid-level wave moving into the Southwest along with antecedent mid-level moisture could bring isolated dry thunderstorms to portions of northern Arizona and New Mexico on Day 5. However, some uncertainty exists with evolution of expected precipitation primarily north of the Interstate 40 corridor from Days 2-4/Tuesday-Thursday. This could prevent higher lightning ignition efficiency so no isolated dry thunderstorms probabilities were introduced. A larger scale upper-level trough and strong mid-level jet could bring broad fire weather threat to areas of the Southwest as early as Day 5/Saturday lasting into early next week for Day 8/Monday. 40 percent critical probabilities were maintained across southeastern Arizona/southwestern New Mexico for Days 5-6/Friday-Saturday. Some timing uncertainty exists in eastward ejection of upper-trough and associated dynamics into the Southern Plains so extension of Critical probabilities into Day 6 was withheld for portions of the Southwest for Day 7-8/Sunday-Monday. ..Williams.. 04/28/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$ ####018000271#### FNUS38 KWNS 282202 PFWF38 DAY 3-8 FIRE WEATHER OUTLOOK AREAL OUTLINE NWS STORM PREDICTION CENTER NORMAN OK 0500 PM CDT MON APR 28 2025 VALID TIME 301200Z - 061200Z FIRE WEATHER OUTLOOK POINTS DAY 3-8 ...
