The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Northern Indiana wrote its last area forecast discussion before this special weather statement went out at Aug 20, 3:36 PM EDT, 3 hours 28 minutes earlier.
Area forecast discussion, Aug 20, 3:36 PM EDT, 3 hours 28 minutes before
Area Forecast Discussion National Weather Service Northern Indiana 336 PM EDT SAT AUG 20 2016 .SYNOPSIS... Issued at 333 PM EDT Sat Aug 20 2016 A cold front will move through the region this evening. Scattered showers and thunderstorms can be expected along and ahead of this front. Cooler and less humid air will arrive later tonight and linger into the start of the new work week. Lows tonight will be in the 60s while highs on Sunday will only be in the lower to middle 70s. && .SHORT TERM...(This Evening through Sunday) Issued at 333 PM EDT Sat Aug 20 2016 Broken line of convection along pre-frontal trough will continue to work east through the forecast area into early evening. Modest shear of 20-30 knots with veering wind profile has led to some weak rotation in storms. However...instability remains weak in the 500- 1000 j/kg range with some pockets around 1500 j/kg. With this limited instability...updrafts have struggled to reach sufficient height for a lot of lightning. Tops have been around 25-30kft and this is around height of -20C level. The combination of modest shear and limited CAPE will still be enough for a few stronger storms with some rotation into the early evening. Isolated strong storms remain possible. Cannot rule out a funnel cloud or even isolated tornado given the circulations we saw earlier this afternoon leave our Michigan counties. However...believe those were enhanced by mesoscale effects of lakeshore and frictional components as line of storms moved off Lake Michigan coupled with stronger shear profiles to our north. Main front to cross the area this evening and early tonight...bringing and end to rain chances. Models have remained consistent with secondary and tertiary short waves driving through mean trough Sunday with wrap around moisture clipping our far north. Did add a low chance PoP for these features. Models also showing 500- 1000 j/kg CAPE with residual moisture and cold air advection aloft with steepening low level lapse rates. Included mention of thunder though expect coverage to be mainly isolated. It will be a bit breezy...cooler and less humid. Highs only expected in the 70s and lower Michigan sites may stay in the upper 60s if clouds and showers do develop. && .LONG TERM...(Sunday Night through Saturday) Issued at 333 PM EDT Sat Aug 20 2016 Once again with active weather in the near term have generally followed Superblend init. Did limit PoPs once again to less than 60 percent given uncertainty at longer lead times with convection and timing of systems. Otherwise it looks cool and dry Sunday and Monday with warming trend Tuesday into Wednesday. Next system will approach with chances for showers and storms Wednesday and Thursday. Kept Friday and Saturday dry for now with front moving south of area and high pressure building back in per GFS and ECMWF 12z solutions. && .AVIATION...(For the 18Z TAFS through 18Z Sunday Afternoon) Issued at 112 PM EDT Sat Aug 20 2016 Theta-e surge along pre-frontal trough will provide several rounds of showers/embedded thunder through mid afternoon...with additional rain/storms expected late afternoon along a cold front. CIGs mainly in the MVFR to low end VFR range expected, though a period of IFR conditions possible with more organized line of rain/thunder into KSBN early afternoon and KFWA mid afternoon. Winds will likely gust 20-30 knots at times. VFR/dry otherwise tonight-Sunday post-frontal as extensive low VFR stratocu works in. && .IWX Watches/Warnings/Advisories...
