During the late evening hours, an isolated thunderstorm in Madison county briefly had a funnel cloud before an area of winds that were later estimated to be around 80 mph caused a trailer's awning to be blown off and into a nearby tree. Additional tree occurred nearby.

Area Forecast Discussion National Weather Service Indianapolis IN 744 PM EDT Sun Jul 12 2020 .UPDATE... The AVIATION Section has been updated below. && .SYNOPSIS... Issued at 132 PM EDT Sun Jul 12 2020 A quick moving upper level weather disturbance will exit central Indiana this evening...allowing an high pressure to build across the area for the first part of the work week. This will result in dry and slightly cooler weather to start the work week. A warm front is expected to push through the area on Wednesday...allowing the arrival of warm and humid air to Central Indiana for the rest of the work week. This will bring back chances for showers and storms along with hot and humid weather after Wednesday. && .NEAR TERM /Tonight/... Issued at 132 PM EDT Sun Jul 12 2020 Surface analysis early this afternoon shows low pressure in place over western KY. Broad cyclonic flow was in place across Central Indiana as stronger and deep low pressure was found over Quebec. Water Vapor shows an short wave over NE Indiana...pushing east within the flow aloft aloft. Radar shows some TSRA development ahead of the short wave axis...stretching from MIE to near Vincennes. Dew Points remained in the mid 60s. Forecast soundings reveal a favorable column for diurnal convection late this afternoon across Central Indiana...however subsidence will be in play in the wake of the upper trough axis. Thus will continue to focus some afternoon and early evening pops across the south and east parts of the forecast area as the shoer wave exits the area. Model suggest that by 00Z the short wave axis will be over Ohio...and subsidence will be in place across Central Indiana. Forecast soundings show good mid level drying across the area. This is mainly in response to the ridging building aloft over the northern plains states...placing the upper midwest and Indiana within a favorable subsidence area. Thus will trend skies to clear and pops toward dry. Will not stray far from the NBM on Temps. && .SHORT TERM /Monday through Wednesday/... Issued at 132 PM EDT Sun Jul 12 2020 Dry and cooler weather will be expected on Monday and Tuesday as the previously mentioned ridge axis is poised to make slowly progress through the area by Tuesday. This keeps subsidence in place for Monday and Tuesday along with a dry column. Forecast soundings suggest a mid level cap on Monday and Tuesday...which should allow for some sct...flat topped Cu through each day. Meanwhile strong high pressure will be moving through the Great Lakes at the Surface. Thus will trend to Mostly Sunday days and Mostly clear nights through Tuesday Night. Will not stray too far from the NBM on temps. On Wednesday...stronger warm air advection begins as the ridge axis aloft finally moves east of Indiana. This will mark the start of warm air advection amid SW winds aloft. Models suggest strong warm air advection arriving as 850mb temps rise to 18C on Wednesday afternoon. Furthermore a frontal boundary looks to get set up from the Great Lakes to the southern plans...providing an axis for convergence and storm development. Forecast soundings on Wednesday for now show attainable convective temps and some CAPE around 1500 J/KG...which is kinda low for this time of year. Anyways it still is enough to warrant afternoon and evening chances for diurnal convection. Thus will include pops on Wednesday afternoon with temps at or above the NBM. && .LONG TERM (Wednesday Night Through Sunday)... Issued at 224 PM EDT Sun Jul 12 2020 Models are close enough that the National Blend of Models initialization was accepted for most items. Central Indiana will remain in nearly zonal flow through the long term period, with a large upper high to the south. This will allow a surface front to stall somewhere nearby. Pieces of upper energy moving through the flow will interact with the front and create some convection at times. Of course at this stage there remains plenty of uncertainty on exactly where the front will set up and how far north the upper high gets, so will generally have slight chance to chance category PoPs through the period. Will still have higher PoPs though at the start of the period as a stronger upper wave will be moving through. Hot and humid conditions will rule, with the hottest temperatures coming next weekend. How hot it gets depends on how far north the upper high can get. && .AVIATION /Discussion for the 13/00Z TAF Issuance/... Issued at 732 PM EDT Sun Jul 12 2020 This evening's isolated showers and thunderstorms have stayed out of the TAF sites, and expect it to continue like that. So, VFR will be the prevailing flight category for the duration of the TAF period. High pressure will continue to strengthen over the region tonight. Meanwhile, winds will start out northwesterly at 6 to 11 kts, then become light and variable late this evening. && .IND WATCHES/WARNINGS/ADVISORIES...NONE. && SYNOPSIS...Puma NEAR TERM...Puma SHORT TERM...Puma LONG TERM....50 AVIATION...TDUD
