HALBACHWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Milwaukee, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 14, 2:06 PM CDT, 55 minutes earlier.
Area forecast discussion, Jun 14, 2:06 PM CDT, 55 minutes before
Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 206 PM CDT Wed Jun 14 2017 .SHORT TERM... Tonight and Thursday...Forecast confidence is medium to high: Current round of storms will move through west to east through late afternoon, exiting the east between 5 and 7 pm per the latest HRRR. Severe thunderstorms remain possible, with the large hail and damaging winds still the main threats. Looks pretty quiet for the evening and overnight hours as this current shortwave exits the area. A couple models show isolated thunderstorms possible this evening and overnight, so left some low pops going. Otherwise, should see decreasing clouds overnight. Thursday looks quiet for most of the day. Plenty of sunshine with the lingering warm airmass should lead to highs around 90 most places. Tough call on a lake breeze tomorrow, as westerly winds could be near strong enough to hold it off most of the day, but this isn't certain. Threw in a low chance for storms in the west late in the afternoon as a surface trough approaches. Not out of the question to see an isolated storm or two. .LONG TERM... Friday night through Saturday... Forecast confidence is medium. The upper low will track east through Saskatchewan and Ontario. The low-level thermal boundary will likely be laid out across southern WI. A couple of shortwaves moving along this boundary should be the focus for showers and storms. A glance at forecast soundings shows decent instability and shear Friday through Saturday. The heat and humidity will continue through this period. Saturday night... Forecast confidence is medium. Strong shortwave trough moving through Sat evening. This will kick off some thunderstorms and there's a chance for severe. Cooler and drier air will settle in behind the associated cold front. Sunday through Tuesday... Forecast confidence is medium. We will be in cooler northwest flow through this period. Moisture will be limited, but we could see a few showers or sprinkles. The better chance for showers will be Monday night/Tuesday with a stronger shortwave trough. && .AVIATION(18Z TAFS)... Main concern in the short term is thunderstorms this afternoon. The main round of storms will move through west to east across the forecast area through 23Z, with scattered storms likely ahead of this main line. Severe storms with hail/wind the main threats are possible. After storms move through by late afternoon/early evening, may see a few lingering showers and storms through late evening along a weak boundary. Looks mainly dry overnight per several models. Dry weather is likely Thursday into the afternoon, with a shower/storm possible mainly west of Madison by late afternoon. VFR conditions will prevail through Thursday except for lower ceilings and visibilities within storms. && .MARINE... Will continue to keep an eye on the fog potential today, especially as winds become more southeasterly over the nearshore waters. Conditions look good for now though. Otherwise, the main marine concern over the next couple days will be thunderstorm chances, as winds and waves are expected to remain below Small Craft Advisory levels. && .MKX WATCHES/WARNINGS/ADVISORIES...
