520 FXUS63 KOAX 190849 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 249 AM CST Wed Nov 19 2025 .KEY MESSAGES... - Patchy fog and drizzle should diminish slowly through the morning hours. - Another storm system will move into the region Friday, bringing a 20-60% chance for rain across southeast Nebraska and far southern Iowa. - Mild, dry weather returns over the weekend before a third system arrives on Monday. && .DISCUSSION... Issued at 247 AM CST Wed Nov 19 2025 Today through Thursday... Lower visibilities seeped into locations along and east of the Missouri River overnight, as patchy fog and drizzle developed. Temperatures dipped into the upper 30s and low 40s overnight, with the cloud cover keeping the area warm enough to prevent the development of icy patches. Today, cloud cover will slowly decrease from west to east, as easterly winds become southerly this afternoon. This will allow temperatures to rise back into the low to mid 50s today, with upper 40s expected across western Iowa. A weak cold front will drift through the region late Wednesday night/early Thursday morning, brining winds back to the north as low temperatures dip into the mid 30s. The frontal passage still looks to be dry as any notable moisture remains well to the north and south of the forecast area. Subtle upper ridging, ahead of the next trough approaching from the southwestern CONUS, will allow Thursday`s high temperatures to reach into the mid to upper 50s, with a few locations again reaching 60 degrees. Friday through Next Week... The previously mentioned low will eject northeastward toward Kansas on Friday. Models continue to shunt precipitation from this system southward, clipping the southern portion of the forecast area. Even if we see a northward nudge to the system, rain will be forecast due to the primary jet stream locking up the coldest air in Canada. After a dry weekend, a second low will move out of the southwestern CONUS, likely taking a similar path to its predecessor, bringing low precipitation chances to the region early next week. High temperatures will remain in the mid to upper 50s this weekend, and early next week, after a brief dip into the 40s on Friday. But, unfortunately, above normal temperatures won`t last forever. Colder air looks to sink into the region by late next week. && .AVIATION /06Z TAFS THROUGH 06Z THURSDAY/... Issued at 1056 PM CST Tue Nov 18 2025 MVFR ceilings expected to linger into late Wednesday morning/early afternoon, gradually scattering out from west to east. Could also see some patch fog development, along with patchy drizzle, especially near and east of the Missouri River including at OMA. For now kept visibility reductions (4SM) confined to a TEMPO group from 10-14Z when best drizzle potential is expected, but will need to keep an eye on trends for possible prevailing conditions. Otherwise, expect very light winds overnight to turn clockwise and settle in at southerly to southeasterly Wednesday morning, with speeds around 6-11 kts through the day. && .OAX WATCHES/WARNINGS/ADVISORIES...
