(today through Thursday) Issued at 300 AM CST Tue Jan 17 2017 Precipitation had ended across the area prior to midnight with departing weather system located over northern Illinois at 08z. Low clouds had cleared across much of northeast Nebraska early this morning with trend of decreasing clouds expected to spread east during the morning as an amplifying short wave trough moves across eastern Nebraska and western iowa. Weak warm advection moves into the area during the afternoon with northwest winds diminishing during the morning and becoming light west to southwest in the afternoon. Combination of morning clouds and light winds will limit warming initially today but afternoon sun is expected across most of the area and will help boost highs into the mid 30s to near 40. Warming trend for the region then kicks in for Wednesday and Thursday with highs in the 40s to around 50 expected. One drawback will be increasing clouds by Wednesday night into Thursday as another short wave trough lifts out of the southern Rockies into the central plains. .LONG TERM...(Thursday night through Monday) Issued at 300 AM CST Tue Jan 17 2017 The central plains trough then amplifies over the lower Missouri Valley Thursday night and lifts toward the lower Great Lakes on Friday. This system will bring a small chance of some light rain or snow to the area Thursday night. Additional waves then periodically move through the region for the weekend and early next week as the strong westerly flow pattern remains in place. Some chance of rain or snow is expected through the remainder of the extended period with the better chance likely over the weekend. The warmer temperatures expected however should result in mainly rain for most of the area with some rain or snow mix possible where borderline temperatures around freezing exist.

(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1116 AM CST Tue Jan 17 2017 An MVFR cloud deck at KOMA should scatter out by 19-20z. Otherwise VFR conditions until later in the night when some patchy fog could develop by 02-07z. Not confident enough to drop any location into to MVFR, but will go down to 6sm and see how this eventually develops.
