Area forecast discussion, Jul 7, 3:20 PM CDT, 2 hours 47 minutes before
Area Forecast Discussion National Weather Service Grand Forks ND 320 PM CDT THU JUL 7 2016 .SHORT TERM...(This evening through Friday) Issued at 320 PM CDT Thu Jul 7 2016 Main forecast challenge will be pcpn chances for this evening and into Friday. The strongest feature is the upper low over north central ND, moving slowly east. A line of tstms developed in an arc out ahead of this feature, basically from Cooperstown to Devils Lake. Had multiple reports of funnel clouds along this line, but no confirmed tornado touchdowns. As this area continued to lift NE, it ran out of instability and weakened. Some of the stronger cells moved through portions of Nelson and Ramsey counties, and dropped some heavier amounts of rain. For that reason a Flood Advisory was issued for that area until 6 pm tonight. At the moment, cells are all in a weakened state. Shear and instability are not that strong across the area, so a few severe storms are possible, but not likely or widespread enough to warrant a watch. There has been too much cloud cover around through the day. Latest high resolution model output shows the majority of the pcpn staying north of highway 200 tonight, and longest across portions of northwest MN. Some of this pcpn may even linger into Friday. .LONG TERM...(Friday night through Thursday) Issued at 320 PM CDT Thu Jul 7 2016 High pressure will bring diminishing wind to the region. Will have to monitor for fog potential depending on how much rain occurs today. Mid level ridging builds into the FA Saturday dry conditions and moderating temperatures...but still on the cool side of average. With warm advection push and apparent weak wave riding the ridge will maintain low end pops Saturday night. For Sunday through Thursday...Southwest flow aloft expected to develop early in this period as a strong upper low ejects into the western Dakotas and then southern Manitoba. This upper low has trended slower with each of the past few model runs. Details still uncertain...but with the region in the warm sector multiple high impact severe thunderstorm events appear possible. The strongest signal for severe potential is on Monday. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 1247 PM CDT Thu Jul 7 2016 Still have VFR ceilings and vsbys across the area, with the exception of KDVL, which is seeing a tstm now. Thunderstorms will be prevalent across the FA into the early evening, and perhaps beyond that at KTVF and KBJI. As stronger storms move thru ceilings may briefly dip into MVFR levels, but hard to time that at this point. Models also indicate lowering ceilings tonight into Friday morning. Not sure exactly how low to go, so just kept them in MVFR levels for now. Winds overall look to remain on the low side. && .FGF Watches/Warnings/Advisories... ND...None. MN...None. && SHORT TERM...Godon LONG TERM...Godon/Hopkins AVIATION...Godon
