LONG TERM

/SATURDAY THROUGH WEDNESDAY/

Saturday will see the H5 shortwave lift northeast while sfc high pressure moves over the area. Dry conditions are expected with highs in the upper 40s to mid 50s. Southwesterly flow returns as the sfc high pushes away from the area. As the H8 baroclinic zone once again swings across, WAA ensues with temps warming to the upper 60s to low 70s areawide for Sunday. Slightly warmer temps arrive Monday with highs in the 70s and dry conditions.

Aloft, a secondary H5 shortwave lagging behind Friday's/Saturday's trof will retrograde to the southwest, eventually becoming a cut-off low over the Baja peninsula. This places the area in quasi-zonal flow for much of the weekend. Guidance suggests the the closed low eventually lifting northeast by late Monday into Tuesday, turning our flow southwesterly as several waves eject northeast ahead of the main parent low. Thus, our next best chance for precip (40-60% chance) arrives Tuesday into Wednesday. Highs Tuesday warm to the mid to upper 60s and cool to the mid to upper 40s on Wednesday.

AVIATION /12Z TAFS THROUGH 12Z FRIDAY/

Issued at 509 AM CST Thu Mar 5 2026

Dense fog is ongoing across western portions of the area, including OFK. The dense fog is anticipated to last over the next few hours before gradually improving. Visibility as low as one quarter mile is expected at times. Ceilings will remain between IFR and LIFR through the morning at OFK. MVFR ceilings and minor fog are ongoing at LNK and OMA. For LNK, latest satellite trends indicate an increasing likelihood of dense fog overspreading the terminal as low clouds erode. At OMA, IFR ceilings and lower visibility are beginning to develop south of the area. These conditions are expected to spread north over the next couple of hours. Later this morning, an increase in south winds is forecast. This should coincide with quick improvements to visibility and ceilings to VFR conditions by the early afternoon. VFR conditions are anticipated until late this evening. A warm front and strong low-level jet approaches the region late this evening. These feature will support the threat of thunderstorms, MVFR to IFR ceilings, LLWS, and areas of fog as it pushes through the region. An initial timing of thunderstorms has been included in this TAF cycle, but confidence in additional details will increase throughout the day and be added with later TAF issuances.
