401 FXUS63 KOAX 210357 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 1057 PM CDT Thu Oct 20 2016 .SHORT TERM...(tonight through Sunday) Issued at 322 PM CDT Thu Oct 20 2016 Latest water vapor imagery loop shows an upper trough axis just to our east with a weak upstream trough axis sliding southeast from the Dakotas. Otherwise, cool surface high pressure continues to slide southeast across the region this afternoon along with an area of MVFR clouds. Expect this area of high pressure to be centered over the CWA through the evening with light return flow increasing by early Friday morning. Clearing skies and calm winds overnight should allow temperatures to fall to around or just below freezing in most areas. Frost/freeze headlines are done across the entire CWA so there will be no mention in the gridded forecast. Otherwise, very quiet conditions are expected over the next several days with temperatures at or close to normal for this time of the year. .LONG TERM...(Sunday night through Thursday) Issued at 322 PM CDT Thu Oct 20 2016 While temperatures will continue near normal through next work/school week, we will see an upper level disturbances roll through the area providing enough support to increase chances for precipitation. This chance comes early Tuesday morning into Wednesday as a potent shortwave trough moves east across the area. Timing issues have yet to be resolved with ECMWF a bit slower than the GFS. An increase in instability could bring some mention of thunder as well. && .AVIATION...

(For the 06Z TAFS through 06Z Friday night) Issued at 1056 PM CDT Thu Oct 20 2016 VFR conditions are likely through the TAF cycle, with mainly clear skies and unrestricted visibility. Still think a bit of intermittent, patchy MVFR fog is possible, especially near KOFK, but guidance continues to steer away from it, and thus will continue to leave it out of TAFs. Light and variable winds will become southerly by mid-morning, with a bit of gustiness at KOFK, then drop off at sunset.
