Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 1126 PM CST Wed Feb 28 2018 .UPDATE... Issued at 859 PM CST Wed Feb 28 2018 Forecast appears on track so no major changes. Latest CAMS still forecast overnight fog and with low temp/dewpoint depressions in place, have no issue with formation of overnight radiation fog. && .SHORT TERM...(This Evening through Thursday Afternoon) Issued at 345 PM CST Wed Feb 28 2018 Similar set up for tonight and Thursday compared to last night and today. Some more snow melt today with winds generally under 10 mph. Therefore, with winds going light again tonight under mostly clear skies, expect temperatures to again fall to the dewpoint with fog forming again. Expect fog to form mainly in the James Valley and in the Sisseton Hills region with some dense fog. The fog may end up being more expansive by morning. Otherwise, surface high pressure will push east on Thursday with light winds becoming south. Again, the mixing will be weak on Thursday with the snow cover. Thus, it will be difficult for the warmer air to mix down. Still expect highs in the upper 20s to the mid 30s Thursday afternoon under partly cloudy skies. .LONG TERM...(Thursday Evening through Wednesday) Issued at 345 PM CST Wed Feb 28 2018 Warmer air will be prevalent across the CWA for the Thursday night through Sunday period as the models all show south winds dominating in advance of upper level low pressure area moving in from the west. The models continue to all show this large upper level low pressure area off the Pacific northwest coast Thursday night moving into the western U.S. by Saturday. This trough and its associated surface low pressure area and track will be the main weather story for Sunday through Monday night and maybe into Tuesday. The models agree well on the location of the surface low pressure area being in northwest Kansas on Sunday evening. The models then all diverge from there with the strength and track with the system as it lifts northeast across the plains. The EC continued to be the strongest with the surface low pressure area along with holding precipitation in our CWA into Tuesday while the GFS and Canadian had much less qpf and were weaker and quicker. Depending on the track the system will give us several weather scenarios. At this time, it does look like we will be warm enough for rain mainly across the east for Sunday and Sunday night. Expect mainly snow for Monday and Monday night along with stronger northwest winds and colder air. Already have in good/likely chances with this system at this time. We will see what later model runs show as we get closer. && .AVIATION...(For the 06Z TAFS through 06Z Thursday Night) Issued at 1125 PM CST Wed Feb 28 2018 Patchy fog may produce localized MVFR vsbys overnight into early Thursday morning. Otherwise, it should be VFR through most of the period. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. && UPDATE...TDK SHORT TERM...Mohr LONG TERM...Mohr AVIATION...TDK
