Area Forecast Discussion National Weather Service Indianapolis IN 100 PM EDT WED SEP 28 2016 .UPDATE... The AVIATION Section has been updated below. && .SYNOPSIS... Issued at 301 AM EDT Wed Sep 28 2016 An upper level low will loiter in the area into the weekend, keeping cooler than average temperatures and chances for rain in the forecast. Warmer and drier conditions return next week. && .NEAR TERM.../Today/ Issued at 301 AM EDT Wed Sep 28 2016 An upper low will move into the forecast area today. In addition, a surface low will move into Ohio and drag a front through central Indiana. Q-vector convergence progs show decent forcing with this system today. Rain will continue to develop this morning as the system approaches, and currently it looks like the southern and eastern forecast area will see the highest chances for rain as the front moves through the area. Will go likely PoPs there later this morning into early afternoon. (Hi Res Rapid Refresh has higher coverage of rain early this morning across the northern forecast area. Will have to watch for development and may up PoPs there early). After the front passes, the upper low will be moving in with cold air aloft. The steep lapse rates could lead to additional scattered convection developing, so will keep chance PoPs going most areas mid to late afternoon to account for this. It now appears that there will be enough instability to go with a thunderstorm mention everywhere across the area this afternoon. The southeastern forecast area looks to perhaps have some brief sunshine, which could lead to higher instability. SPC has placed the southeastern forecast area in Marginal Risk, and this looks reasonable given the expected instability and cold air aloft moving in (creating a hail threat). Will mention hail in the Hazardous Weather Outlook. MAV MOS and model blend look cool with some potential for occasional breaks in the clouds today. Went warmer, but not quite as warm as the MET MOS. && .SHORT TERM.../Tonight through Friday night/ Issued at 301 AM EDT Wed Sep 28 2016 Focus remains on chances for rain through the period. Models are close enough that a blend was used. As the upper low meanders out of and then back into Indiana, chances for rain will continue through the Short Term. For much of the period, PoPs will be in slight chance to chance category, with highest PoPs generally across the eastern areas, closer to the upper low. Higher chances of rain will move in Thursday night into Friday, as more potent energy rotates into the area from the northeast. Will go high end chance category to low likely PoPs across the north during that period, with chance PoPs south. There is still some uncertainty on the path of the upper low and thus locations and timing of better forcing, so some changes in the forecast remain a good possibility through the next couple of days. Generally stayed close to a model blend for temperatures, as MAV MOS is too cool for highs at times. && .LONG TERM /Saturday through Tuesday night/... Issued at 334 AM EDT Wed Sep 28 2016 Light rain showers will continue to affect portions of central Indiana, mainly northern, through Sunday morning due to an upper low. At that point, GFS and Euro agree on the upper low moving off to the northeast and into eastern Canada. Dry conditions will then return and persist through the end of the extended period as high pressure strengthens over the region. Latest initialization is representative of this pattern, so no changes were needed. Below normal temperatures can be expected on Saturday with highs only in the upper 60s/low 70s. A weak warming trend will quickly commence by Sunday though, and temperatures will climb back to normal for the beginning of the week. && .AVIATION /Discussion for the 28/18Z TAF Issuance/... Issued at 100 PM EDT Wed Sep 28 2016 Mostly VFR with scattered showers through this evening. Then areas of MVFR ceilings and visibilities or lower late tonight and Thursday morning. An area of low pressure over central Indiana will continue to move southeast. As a result there will be scattered showers through the period. An isolated thundershower possible through 00Z...but chances are too low to include mention in TAF's at this time. Prevailing Ceilings will be at or above 7 thousand feet through this evening then lowering to 1 to 2 thousand feet late tonight with visibilities of 3 to 5 miles possible late tonight in fog and or scattered showers. Windds will become north 5 to 8 knots this afternoon and 5 knots or less tonight. && .IND Watches/Warnings/Advisories...NONE. && SYNOPSIS...50 NEAR TERM...50 SHORT TERM...50 LONG TERM....TDUD AVIATION...JH
