000 FXUS63 KOAX 162326 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 626 PM CDT Sat Mar 16 2024 .KEY MESSAGES... - Very high fire danger will continue through 8pm this evening for portions of northeast Nebraska and is likely again across the entire area Sunday. We will keep a close watch for the potential for some extreme fire weather conditions Sunday afternoon but looks fairly marginal. - Colder temperatures move in Sunday with overnight lows into Monday morning falling into the teens to low 20s. Wind chill values Monday morning will be in the single digits at times. Temperatures gradually warm back up toward the latter half of next week. - Small chances for precipitation return beginning Wednesday night with chances increasing into next weekend. && .DISCUSSION... Issued at 310 PM CDT Sat Mar 16 2024 A cold Canadian airmass will dive south across the Dakotas overnight bringing unseasonably cool temperatures to the region Sunday. With gusty northwest winds of 30-35 mph and highs only in the 40s, wind chill values will be in the 20s and 30s through the day Sunday. We have not quite managed to reach extreme fire weather conditions this afternoon and with a cooler airmass expected for Sunday, do not think we will be able to reach the 20% RH criteria for extreme fire danger on Sunday. By Monday morning, a cold surface high pressure will build overhead dropping Monday morning lows into the teens and 20s. With northwesterly winds under 12 kts, wind chill values Monday morning could drop into the single digits at times. Northwesterly flow aloft is expected to persist through much of next week while a southwestern CONUS upper low slowly weakens and ejects into the southern Plains by mid-week. It still appears that much of the beneficial moisture associated with this low will remain well to our south. Temperatures should remain near-normal or slightly above normal until later in the week when the pattern looks to become more active. Upper level flow over the central CONUS becomes southwesterly as a deepening western trough moves onto the Pacific coast next weekend. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/...

Issued at 623 PM CDT Sat Mar 16 2024 VFR conditions are expected through the period, with gusty winds at 25 kts out of the northwest still holding on for the next hour or two. The few clouds that exist now should gradually decrease this evening with an increasing amount around 14z tomorrow morning. Some of those clouds may even hang around FL030 and cloud have a sprinkle or two out of them. Otherwise, winds will once again increase out of the northwest with gusts generally ranging from 25 to 30 kts through 00z tomorrow evening.
