Area Forecast Discussion National Weather Service Indianapolis IN 435 PM EDT MON JUN 20 2016 .UPDATE... The AVIATION Section has been updated below. && .SYNOPSIS... Issued at 319 PM EDT Mon Jun 20 2016 A rather active period is setting up across central Indiana through mid-week with several chances for severe weather. The first chance for showers and thunderstorms will come this evening and tonight as a cold front enters central Indiana from the northwest. The main severe threat with these storms will be damaging winds. Activity will subside a bit by tomorrow, with any severe threat confined to southern Indiana, closest to the aforementioned front. The highest chance for a widespread severe event will be on Wednesday/Wednesday night with the northern two-thirds of the forecast area under an Enhanced Risk for severe weather and the southern third under a Slight Risk. An early round of showers and thunderstorms can be expected on Wednesday morning followed by a much stronger round on Wednesday afternoon and evening. The main severe threats will be damaging winds and isolated tornadoes. After a bit of a reprieve late in the week, additional showers and thunderstorms will be possible for the weekend as a warm front wraps around into central Indiana. && .NEAR TERM /This Evening and Tonight/... Issued at 319 PM EDT Mon Jun 20 2016 The main focus of the near term period will be the threat for strong to severe thunderstorms this evening and into tonight. Current radar mosaic is showing convective activity spreading from northeast Illinois to northern Indiana ahead of approaching cold front. The front will have decent instability to work with when it enters Central Indiana after Mon 21Z. Current LAPS data is showing CAPE values near 2400 J/kg in places with temps in the low 90s and dewpoints in the upper 60s/low 70s. Best chances for severe potential will be in the Mon 23Z-Tue 02Z time frame, quickly tapering off after that. Will leave chances for showers and thunderstorms into the night though acoss central and southern portions of the forecast area closest to frontal boundary. Overnight lows are projected to range from the mid 60s across the northern counties where there will be some clearing to low 70s across the southern counties where clouds and rain will linger. Models seem to have a handle on the frontal boundary, so will stick close to a blend for tonight. && .SHORT TERM /Tomorrow through Thursday night/... Issued at 319 PM EDT Mon Jun 20 2016 The main focus of the short term will be the threat for widespread severe development Wednesday/Wednesday night. First, scattered showers and thunderstorms will be possible across southern portions of Central Indiana tomorrow which will be closest to cold front draped across Kentucky. Elsewhere, trended toward a dry forecast across the northern and central counties. After a bit of a lull tomorrow evening, clusters of showers and thunderstorms will form in the warm advection spreading into Central Indiana from the southwest early Wednesday morning. Surface low will exit Nebraska and push convective activity farther northeast into Central Indiana. As environment destabilizes further tomorrow afternoon with MUCAPES near 3000 J/KG, the severe threat will increase late in the day and continue into the night. Impressive lapse rates in excess of 7C and a strong 850 mb jet will be conducive to widespread damaging winds and isolated tornadic development. Severe threat will taper off by Thursday morning, but residual showers and isolated thunderstorms will linger into the day. && .LONG TERM /Thursday Night through Monday|/... Issued at 244 PM EDT Mon Jun 20 2016 After the active weather for midweek...much quieter conditions will arrive for the beginning of the extended as high pressure builds south into the region as the frontal boundary shifts south into the Tennessee Valley. Dry and less humid conditions will continue through early Saturday as the high passes through the region. The aforementioned frontal boundary will return back north over the weekend in response to low pressure developing over the northern Plains ahead of a vigorous upper low. The upper low and surface wave will track east into the northern Great Lakes by early next week with the front moving back through the region with chances for thunderstorms. Ridging aloft by late week will support highs returning into the upper 80s and early 90s for the weekend. && .AVIATION /Discussion for the 202100Z KIND TAF Update/... Issued at 435 PM EDT Mon Jun 20 2016 Convective clusters developing currently developing over northern Indiana into northeast Illinois, ahead of a cold front. Air mass south of convection is moderately unstable, so additional development is possible. Appears convective threat at the KIND terminal will increase after about 210000Z-210100Z. Previous discussion follows. VFR conditions expected throughout the forecast period with the exception of brief restrictions within thunderstorms. Increasingly moist unstable airmass over the region with a well developed cu field now established. Frontal boundary to the north over the Great Lakes continues to approach. Expect isolated convection to fire after 19-20Z as convective temps are met across central Indiana. With limited coverage anticipated...will continue with a VCTS mention at all terminals through the late afternoon and early evening. A greater threat for convection associated with the front could impact the terminals during the evening and early overnight. Confidence remains lower than desired at this time however with respect to precip coverage...so will maintain the VCTS mention through about 06Z for now. Any convective threat will diminish after 06Z as the front shifts south of the region. Mostly sunny skies will return for Tuesday morning as weak high pressure builds into the area. Gusty W/SW winds through early evening will diminish to less than 10kts and veer to northwest after midnight. && .IND Watches/Warnings/Advisories...
