AREA FORECAST DISCUSSION National Weather Service Sioux Falls SD 333 PM CDT Fri Jul 5 2019 .SHORT TERM...(This Evening through Saturday) Issued at 320 PM CDT Fri Jul 5 2019 Focus for lingering precipitation over SW Minnesota revolves around resultant MCV from morning convection. This same area of SW Minnesota into far northern Iowa stands some chance of redevelopment thru early evening with enhancement in the Cu noted across our far eastern counties as of mid afternoon. A potential secondary area to watch for precipitation revolves around a vort lobe sneaking along the ND/SD border this evening. This will be enough to spark additional shower and thunderstorm activity over the western Dakotas that will then try to track east thru late evening. A pronounced weakening trend is expected though as it outruns its better instability ribbon. This idea is further supported by most CAM solutions, largely fading the northern extent of it off as it runs toward/down the the MO River valley with the latest guidance diving the rest of this activity off to the southwest. Broad upper level subsidence and subtle mid level ridging should diminish much of the precipitation chances across the area tonight into Saturday. The exception may come if a well enough developed MCV can form out of overnight convection to the west, pairing with an active jet streak overhead, and thus kept slight chance wording for precipitation in the forecast, although bulk of high res guidance not overly excited about this potential. Saturday afternoon temperatures will run in the mid 70s to lower 80s with dewpoint values more comfortable than as of late with largely lower to mid 60s. .LONG TERM...(Saturday Night through Friday) Issued at 320 PM CDT Fri Jul 5 2019 A compact shortwave and jet entrance region sneaks thru on Sunday that depending on its timing, may provide for a couple showers and thunderstorms but nothing widespread expected at this time. Upper level ridge begins to amplify some as we move into Monday with the ridge axis shifting east of our area as the next trough begins to move into the Pacific Northwest. This will allow for temperatures to tick upward from the upper 70s to lower 80s for Sunday into the lower to mid 80s for Monday. Dewpoints will also be on the rise by early next week. First piece of energy out of the southwest flow aloft arrives late Monday into Monday night along with an eastward trudging front. This will allow for convection to develop, particularly across western and central portions of the Dakotas where the better theta-e and instability ribbon exists. Previously mentioned front plows thru Tuesday and Tuesday night and will bring additional thunderstorm chances. Instability and shear values would suggest this would be a time frame to monitor for potential severe weather threat. Surface high pressure begins to set in by the second half of Wednesday into Thursday as upper level ridging builds. This will return us to the occasional ridge rider thunderstorm chances thru late week, although certainly more dry periods than wet. The building ridge will also bring warmer temperatures with mid 80s to near 90 possible by Friday. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1216 PM CDT Fri Jul 5 2019 Remnant MCV spinning over far eastern South Dakota in to western Minnesota continues to produce rain and occasional rumble of thunder. This will focus the bulk of the precipitation chances thru the evening either north or east of the terminals with chances too low at the terminals themselves to include mention in the TAFs. Areas of MVFR to locally IFR ceilings are currently noted in as of the noon hour with these periods of these sub VFR ceilings expected to continue into the evening. && .FSD WATCHES/WARNINGS/ADVISORIES...
