000 FXUS63 KOAX 282334 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 634 PM CDT Tue Mar 28 2017 .SHORT TERM...(Tonight through Friday) Issued at 241 PM CDT Tue Mar 28 2017 Precip chances dramatically increase tonight into Wednesday as large scale forcing for ascent overspreads the region. Pops moving into the categorical range through the night, with instability parameters suggesting thunder remains just south of the forecast area across eastern Kansas and Missouri. Bumped up lows a couple of degrees for tonight, now in the lower to mid 40s. Widespread precip continues Wednesday across the forecast area, with limited instability moving into areas south of I80 during the afternoon and evening. Going to be a very wet, somewhat raw day, with northeast winds at 15 to 25 mph, and a very limited diurnal rise of 2 to 4 degrees in the rain if that, with highs still in the mid 40s. Keep the rain gear handy. Precip threat continues into Wednesday night as the deformation band remains across the region. There will also be a dry slot moving into the area, which may have an impact on where that band sets up, but will have highest categorical Pops that continue along Interstate 80 during the evening. Precip rates really begin to diminish after midnight Wednesday night, but showers still linger into Thursday morning. Could even be a few snow flakes mixing in late Wednesday night into Thursday morning in northeast NE, but no accumulation expected. Rain ends altogether by Thursday afternoon. Highs Thursday should still cool in the upper 40s to lower 50s. Remainder of the short term remains dry, with highs still below normal Friday in the lower 50s. .LONG TERM...(Friday night through Tuesday) Issued at 241 PM CDT Tue Mar 28 2017 Looks like another wet and somewhat dreary weekend as precip chances spread into the region as a result of another closed upper low moving out of the southwest CONUS. Rain threat increases through the day Saturday, but especially Saturday afternoon and into Sunday. Additional precip chances Monday into Tuesday. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 630 PM CDT Tue Mar 28 2017 MVFR ceilings continue at KOMA/KLNK and will be advancing north into KOFK this evening.

We should see visibilities decrease through the day on Wednesday as well as ceilings lowering into IFR range.
