Area Forecast Discussion National Weather Service Indianapolis IN 1226 PM EDT Wed May 24 2017 .UPDATE... The AVIATION Section has been updated below. && .SYNOPSIS... Issued at 330 AM EDT Wed May 24 2017 Wet weather will occur today through midday Thursday as low pressure deepens over the Ohio valley and drifts north across Indiana. This low pressure system will move on to the east and a ridge of high pressure will move east across Indiana Thursday night and early Friday. Wet weather will return late Friday through most of the weekend as a frontal system and a couple of low pressure systems move our way. Temperatures will become a little cooler early next week as an upper trough digs into the upper midwest. && .NEAR TERM /Today through Thursday/... Issued at 330 AM EDT Wed May 24 2017 Showers have been increasing over the lower Ohio valley as well as northeast Illinois and parts of extreme northwest Indiana. Surface chart indicates a weak area of low pressure centered a little south of Louisville at 07Z. Models strengthen this low pressure system as a closed upper low over eastern Iowa moves southeast. For today leaned heavily towards the high res model which spread numerous showers into our southwest and southern sections this morning and spreads this area north across the rest of our region this afternoon. Will go with definite POPS most areas today...but this will not happen until this afternoon across our north. The low pressure system will deepen and move north across central Indiana today. Models indicate MU capes of 500 to 1000 J/KG this afternoon which will result in a chance of thunderstorms this afternoon and a slight chance of thunderstorms into early evening. Will continue with likely POPS all but far west tonight and then decreasing chance of showers Thursday as the surface low moves on to the east. With clouds and precip cut temperatures slightly across the southwest half of our forecast area today. There may be a period late morning where temperatures could rise into the upper 60s across our northeast before the showers arrive. Anyways highs all areas will be in the 60s today. Went with lows in the middle 60s tonight which was slightly above a MOS blend. On Thursday highs will range from the middle 60s east to lower 70s southwest where some Sun may occur by late Thursday. && .SHORT TERM /Thursday Night through Friday Night/... Issued at 330 AM EDT Wed May 24 2017 A ridge of high pressure will move east across Indiana Thursday night and Friday bringing a period of dry weather. An area of low pressure will move our way Friday night. The GFS spreads precipitation by late Friday morning...while NAM keeps us dry until Friday evening...while the EURO and Canadian by late Friday afternoon. Will go with a blend...but slightly slower than CONSALL and SuperBlend POPS. Raised POPS to likely some areas Friday evening as this is most likely time for precipitation to occur and models indicate pretty good forcing. Concerning temperatures stayed close to a MOS blend with highs 75 to 80 Friday and slightly above a MOS blend Friday night with lows in the lower to middle 60s. && .LONG TERM /Saturday through Tuesday Night/... Issued at 341 AM EDT Wed May 24 2017 Models continue to trend toward an active weather pattern throughout the extended period. First, showers and thunderstorms are expected to develop along a surface low's frontal boundary on Saturday. After that, additional forcing will be provided by an upper low progged to drop into the Upper Midwest for the second half of the weekend. There will be a lull in activity from Sunday night into Monday as the forecast area falls into a dry slot. However, additional waves of energy will resume around the upper low by Monday afternoon, triggering additional showers and thunderstorms through the end of the period. Meanwhile, temperatures will start out above normal for the weekend with highs in the upper 70s/low 80s, but they will trend closer to normal by Monday and Tuesday. && .AVIATION (Discussion for 241800Z TAFs)... Issued at 1226 PM EDT Wed May 24 2017 Expect poor flying weather much of the time. For the afternoon, visibilities will be mostly MVFR in rain while ceilings are largely VFR, but occasionally MVFR. Widespread IFR and areas of LIFR are going to form overnight as low pressure crosses Indiana, rain continues, and fog develops. There should be slow recovery to VFR during the day Thursday. Thunderstorms could be embedded in larger areas of rain today and tonight. The wind should stay mostly northwest at 5-15 knots. && .IND WATCHES/WARNINGS/ADVISORIES...
