839 FXUS63 KOAX 131108 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 508 AM CST Thu Nov 13 2025 .KEY MESSAGES... - Unseasonably warm Friday with the potential for record- breaking temperatures. - Very high fire danger in northeast Nebraska Friday afternoon. - 40-50% chance of precipitation Monday. This will most likely be rain, but there is about a 10% chance of accumulating snow in the northern reaches of the forecast area. && .DISCUSSION... Issued at 211 AM CST Thu Nov 13 2025 Today and Friday: Mid-level heights will build over central North America today ahead of an intensifying trough, which will move into central Canada and the north-central U.S. Friday into Friday night. At the surface, a ridge is shifting away from the region to the east early this morning with a deepening lee trough over the High Plains. Light winds associated with the departing ridge may allow for some patchy fog development prior to daybreak along and east of the MO River. Otherwise, a fair amount of high-level cloudiness is expected to linger this morning, before decreasing by afternoon. We`ll see warmer temperatures today (compared to Wednesday) with highs in the 60s to around 70. A more moist boundary layer currently located across the Ozark Plateau into ArkLaTex will be advected into portions of southeast NE and southwest IA this afternoon into tonight with dewpoints increasing well into 40s. That moisture increase will combine with decreasing surface winds to support of fog development in those areas late tonight into Friday morning. On Friday, surface winds will switch to more of a southwesterly direction in response to a vigorous low pressure system moving through central Canada. As a result, a drier and warmer low- level air mass will overspread the region with temperatures warming into the 70s at most locations. There is a good chance that the record high temperature at Norfolk (72/2001) will be broken with the records at Lincoln (75/1990) and Omaha (76/1964) also being challenged. The dry and warm conditions will also contribute to very high fire danger Friday afternoon in northeast NE, mainly west of a line from Norfolk to Hartington. This Weekend: The mid-level trough mentioned in the previous section will continue into eastern Canada and the Great Lakes with northwest flow developing across the northern and central Plains. A surface cold front associated with the Canadian system will move through our area Saturday morning with no precipitation expected. Highs on Saturday will be cooler than those on Friday, but still above normal with readings in the 60s. Surface high pressure will build into the mid-MO Valley Saturday night into Sunday with highs on Sunday into the mid 50s to low 60s. Monday through Wednesday: The primary feature of interest this period is a short-wave trough, which is forecast to move from the Rockies into the central Plains Monday. That system will bring increasing precipitation chances (40-50% PoPs) to the region at that time. Model differences continue in the track and intensity of that mid-level system and the associated surface low. The 00z GEFS maintains a more southern track compared to the EPS/EPS-AIFS and CMCE, which results in comparatively more members (GEFS) showing minor snow accumulations in northeast NE. This forecast update will continue to indicate mainly rain with areas of a rain-snow mix in northeast NE Monday morning and Monday evening when temperatures will be cooler. The models depict the next storm system potentially moving into the Great Plains Wednesday or Wednesday night, which would bring another chance of precipitation to the region. Highs on Monday will be a function of the storm track with readings in the 50s currently indicated. Slightly cooler temperatures are forecast Tuesday and Wednesday. && .AVIATION /12Z TAFS THROUGH 12Z FRIDAY/... Issued at 508 AM CST Thu Nov 13 2025 VFR conditions will prevail through most of the forecast period with decreasing high-level clouds (FL200-250) today. During the last 6 hours of the forecast, there is a consistent model signal for fog development across portions of southeast NE and southwest IA with KOMA the most likely terminal location to be affected. Otherwise, south winds are expected to strengthen to 11-14 kt by 16z before diminishing to less than 12 kt by 14/00z. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.
