Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 342 PM CDT WED JUN 29 2016 .UPDATE... Issued at 341 PM CDT WED JUN 29 2016 Severe thunderstorm watch 310 is in effect for Corson, Dewey and Stanley counties until 8 PM MDT /9 PM CDT/. && .SHORT TERM...(This Evening through Thursday) Issued at 254 PM CDT WED JUN 29 2016 Forecast challenges in the next 24 hours include convective potential/timing/coverage this afternoon through early Thursday along with how cool high temperatures will be on Thursday. Currently, temperatures are warming through the 80s on light winds and a mostly sunny sky. There are a few clusters of thunderstorm activity across southwestern North Dakota tracking southeast across the region. Storms are not expected to maintain or redevelop very far into this cwa. If convection can hold together long enough to make it into Corson county, it is timed to move into the county within the hour, and timed to reach Mobridge by shortly after 7 PM CDT. Storms have developed within the most moisture-rich air at 850hpa in conjunction with the area of best mid-level forcing and upper level lift. Expect the worst conditions associated with these thunderstorms to be brief strong wind gusts /large temp-dewpoint depressions aiding in 1000-1400J/kg DCAPE values/, heavy downpours and cloud to ground lightning. Tonight, a strong Canada-sourced cold front /near the international border/ will sweep southward across the northern plains, including this cwa, wringing out any available low level moisture through Thursday morning. CAMs have been hinting off and on today that isolated to scattered showers and thunderstorms will work southward through the region associated with the forcing from this front. For this reason have continued to time some small pops through the cwa overnight. The Rapid Refresh model is also continuing to imply some of this low level moisture is converted into post-frontal mvfr/vfr stratus which advects into the cwa between 09Z and 15Z Thursday. Skycover may need a little tweaking if that scenario pans out. Thursday, the cold air advection noted in the 925hpa and 850hap thermal progs lends support to forecast high temperatures only in the mid 70s across northeast South Dakota and west central Minnesota to the low/mid 80s over central South Dakota. There may be a few stray showers or weak thunderstorms ongoing across the southern half of the cwa at the start of the Thursday day period, but by and large, Thursday is expected to be cool and dry on northerly breezes. .LONG TERM...(Thursday Night through Wednesday) Issued at 254 PM CDT WED JUN 29 2016 Based on the 12Z model runs, the holiday weekend is looking much drier than before. While models are suggesting a storm system will track across the region Friday night through Saturday, it largely misses this CWA. Thus pops have been greatly reduced during that time period. There are additional chances for showers and thunderstorms Monday through Wednesday as the upper level flow pattern becomes zonal. Temperatures during the long term will begin on the cool side with highs on Friday only in the mid to upper 70s. Temperatures will slowly warm above normal for the holiday weekend. Highs by Monday should climb into the 80s and 90s. Temps in the 90s are expected Tuesday and Wednesday. && .AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon) Issued at 1211 PM CDT WED JUN 29 2016 Expect good VFR to prevail over the next 24 hours. A strong cold frontal passage overnight tonight could spark a few showers or thunderstorms. Did introduce some preliminary thunder mention/timing into the KMBG TAF to highlight this potential. One other potential bi-product of this fropa is one or two areas of MVFR cigs trying to work down into northeast South Dakota /KABR and KATY/ Thursday morning. Will continue to monitor satellite/observations and rapid update short term model guidance for this potential. && .ABR Watches/Warnings/Advisories... SD...NONE.
