Area forecast discussion, Aug 30, 3:40 PM CDT, 2 hours 28 minutes before
Area Forecast Discussion National Weather Service Aberdeen SD 340 PM CDT TUE AUG 30 2016 .SHORT TERM...(This Evening through Thursday Night) Issued at 339 PM CDT TUE AUG 30 2016 A weak frontal boundary returning northward this afternoon along with surface heating has resulted in quite a bit of low and mid level clouds over our cwa. These should dissipate/lift north through the evening. Otherwise, surface high pressure centered in Canada with ridging extending south into the northern plains will build ever so slowly east through the Thursday night. With surface low pressure moving in from the west, the surface pressure gradient will be tightening up along with an increasing llj. Therefore, south winds will slowly be on the increase from Wednesday into Thursday. This flow will also keep the above normal temperature trend going through the short term with highs ranging from 80 to 90 or so. With sharp upper level ridging moving across our region bringing general subsidence and low rh air, expect little or no cloud cover through the period along with dry conditions. Fire weather conditions may be an issue towards Thursday. .LONG TERM...(Friday through Tuesday) Issued at 339 PM CDT TUE AUG 30 2016 The extended will be dominated by an upper trof that slowly progresses from the Pacific Northwest into the central CONUS. There appears to be several shortwaves embedded within the longwave trof which, along with a front stalled across the northern/central plains and broad area of high pressure to the east, will result in a period of inclement weather which spans Sunday through Tuesday. Cooler air will eventually work into the CWA towards the end of the period as well. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday Afternoon) Issued at 1225 PM CDT TUE AUG 30 2016 VFR for all terminals with a south/southeast wind. && .ABR Watches/Warnings/Advisories...
