(Today through Tuesday) Issued at 249 AM CDT Sun May 28 2017 Quiet weather on tap today with breezy northwest flow and plenty of sunshine. High temps climb into the upper 70s to lower 80s, and winds will be northwesterly at 15 to 25 mph. Models are now hinting at a weak currently over the northern Rockies moving into the local area tonight. This may touch off isolated showers but little if any meaningful rain is expected and it could very well just be a few sprinkles. Pleasant weather continues for Memorial Day with continued breezy northwesterly flow, but slightly cooler temperatures in the lower to mid 70s. Similar conditions expected for Tuesday, although there will be a slight chance of afternoon showers along the KS/NE border as a reinforcing front moves in from the north. .LONG TERM...(Tuesday night through Saturday) Issued at 249 AM CDT Sun May 28 2017 Dry weather expected Wednesday, but shower/storm chances return Wednesday night into Thursday as moisture and instability build northward from the southern Plains. Spotty rain chances remain in the forecast Friday into Saturday, although models are not in general agreement of timing and placement, thus confidence in the forecast details by days 6/7 are somewhat low.

&& .AVIATION...(For the 06Z TAFS through 06Z Sunday night) Issued at 1119 PM CDT Sat May 27 2017 Current water vapor imagery depicts the primary mid-level trough axis progressing through the mid MO Valley with a secondary vorticity lobe shifting southeast across SD. These features are generally associated with mid and high-level cloudiness with some light shower activity noted with the latter disturbance over south-central into southeast SD. Latest short-term model guidance suggests that this precipitation should decrease in areal coverage while moving into northeast NE over the next 2-3 hours. Therefore, we will not include any mention in the KOFK TAF. Light northwest winds will strengthen and become gusty by late Sunday morning or early afternoon before diminishing by Sunday evening. VFR conditions will prevail with mainly passing mid and high- level clouds. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None. IA...None. && $$ SHORT TERM...DeWald LONG TERM...DeWald AVIATION...Mead
