Area forecast discussion, Aug 12, 6:59 AM EDT, 14 minutes before
Area Forecast Discussion National Weather Service Northern Indiana 659 AM EDT Sun Aug 12 2018 .SYNOPSIS... Issued at 328 AM EDT Sun Aug 12 2018 Scattered storms are expected to develop today over northwest Ohio and then expand into northeast Indiana this afternoon as an upper low forms over Ohio. The storms will end this evening. An upper level ridge will then build into the region and be accompanied by dry and warmer weather with highs approaching 90 by Tuesday. && .SHORT TERM...(Today and Tonight) Issued at 328 AM EDT Sun Aug 12 2018 An upper low will develop over Ohio today at the base of a trof. Upper level jet support and disturbances embedded in the flow were supporting storms overnight over southeast Lower Michigan. The latest convective allowing models have reasonable agreement for further storm development later today over northwest Ohio expanding into northeast Indiana this afternoon. Have adjusted storm chances in this regard. One apparent hail producing cell overnight with a significant 60 DBZ core appeared to form and be sustained just east of the jet axis in the left exit region of the upper jet over southeast Lower Michigan. While widespread severe storms are not expected today, an isolated storm may become strong to severe as this region of the jet translates south. Otherwise, temperatures will be close to normal with highs 80 to 85. && .LONG TERM...(Monday through Saturday) Issued at 328 AM EDT Sun Aug 12 2018 An upper level ridge will build into the region Monday and be accompanied by dry and warmer weather with highs approaching 90 by Tuesday. Have increased storm chances during the middle of the week as the next system moves into the area. It looks like a good chance for widespread rainfall amounts of half an inch to an inch by late Thursday as precipitable water value rise close to 2 inches. Otherwise, late in the week looks mostly dry with highs around 80. && .AVIATION...(For the 12Z TAFS through 12Z Monday Morning) Issued at 658 AM EDT Sun Aug 12 2018 Hi res models continue to show a small threat of a shower or storm near KFWA but again have left out for the time being with low confidence on coverage and chance of occurrence. Otherwise VFR conditions expected. Some of the models do indicate some HZ/BR potential overnight but not overly confident on this either so have left out. && .IWX WATCHES/WARNINGS/ADVISORIES...
