Area forecast discussion, Jun 16, 3:27 PM EDT, 2 hours 18 minutes before
Area Forecast Discussion National Weather Service Indianapolis IN 327 PM EDT Fri Jun 16 2017 .UPDATE... Synopsis...Near term and Short Term sections have been updated below. && .SYNOPSIS... Issued at 327 PM EDT Fri Jun 16 2017 High pressure ridge over the southeast U.S. will retreat to the east. Low pressure moving into the central plains will track across the upper midwest and Great lakes over the weekend. A cold front will push across Indiana by Sunday. Dry and slightly cooler weather will occur early next week after the weekend. But warmer weather and a chance of more storms will return by the middle of next week. && .NEAR TERM /Tonight and Saturday/... Issued at 327 PM EDT Fri Jun 16 2017 Radar indicated scattered thunderstorms across the middle Mississippi valley...southern great lakes and and south central Ohio. Models and water vapor satellite indicate a weak upper disturbance will move east across northern Indiana early this evening. Air mass over central Indiana has been capped and nothing has developed in our area so far. The rapid refresh model indicates there could be an isolated thunderstorm over northern and far western sections early this evening...then mostly dry weather will occur overnight with perhaps a slight chance of more storms reaching western sections towards daybreak. Will keep areas from INDY and to the southeast dry overnight with slight chance POPS north and west early this evening and slight chance POPS mainly west again late tonight. On Saturday there will go with chance POPS most areas by afternoon as another weather disturbance moves our way along with a bit more moisture. Lows tonight will be in the upper 60s to near 70 and highs Saturday will be in the middle 80s to around 90 which is close to a MOS blend. && .SHORT TERM / Saturday night through Monday/... Issued at 327 PM EDT Fri Jun 16 2017 Forecast challenges focus on storm chances Saturday night into Sunday as a very warm and unstable airmass will occur ahead of a cold front approaching from the northwest. Models indicate two waves of convection with one moving our way and weakening late Saturday and then a stronger one moving our way Saturday night. Air mass will be quite unstable with MU capes in excess of 2000 J/KG and models hint at a possible MCS Saturday night. Will go with likely POPS over northern sections and high chance POPS elsewhere Saturday night. Sunday could be wet as well as a cold front moves through our way. Will go with likely POPS south and chance POPS elsewhere Sunday with storms ending from the northwest late Sunday. Other than a slight chance of storms south Sunday evening...mostly dry and cooler weather will occur Sunday night and Sunday as high pressure behind the cold front builds east. The blended MOS gives 20 percent POPS far northeast late Monday...but all in all expect dry and cooler weather to the the rule. Stayed close to a MOS blend on temperatures most periods with lows in the lower 70s Saturday night and lower 60s Sunday night. Highs will be in the lower 80s Sunday and upper 70s to near 80 Monday. && .LONG TERM /Monday night through Friday/... Issued at 225 PM EDT Fri Jun 16 2017 Dry weather will start the long term for Monday night in the wake of a frontal passage. Then there will be only small or slight chances for thunderstorms until Wednesday night while broad high pressure is in place from the Plains through the Ohio Valley. From Wednesday night on better chances for thunderstorms will arrive as the upper pattern flattens out and a a couple of surface system approach and move through the area. Temperatures will climb by a degree or two each day, with highs reaching the middle 80s to around 90 by Friday and low Friday morning getting back into the upper 60s to lower 70s. && .AVIATION /Discussion for the 161800Z TAF Issuance/... Issued at 105 PM EDT Fri Jun 16 2017 VFR through the period. High pressure ridge over the southeast U.S. will dominate our weather. A weak upper disturbance may produce an isolated thunderstorm over northern Indiana this afternoon and another disturbance approaching from the west may produce widely scattered thunderstorms most areas later Saturday. Otherwise...expect mainly high thin clouds with a few-sct clouds around 7 thousand feet some areas. will mention VCTS KLAF and KHUF after 15Z Saturday and IND Saturday afternoon. && .IND WATCHES/WARNINGS/ADVISORIES...
