Area Forecast Discussion National Weather Service Green Bay WI 342 PM CDT Tue Jul 16 2019 Forecast discussion for routine afternoon forecast issuance .SHORT TERM...Tonight and Wednesday Issued at 342 PM CDT Tue Jul 16 2019 The main forecast challenge will continue to be precipitation trends as the atmosphere is ripe with moisture, just waiting for a trigger to set more thunderstorms. The 19Z MSAS surface analysis showed a very weak cold front that extended from eastern Upper MI southwest through east-central WI, to southwest WI. So far, no precipitation had developed on this front and the cumulus field on visible satellite has showed no trends of building. Of more interest was a cluster of thunderstorms over south-central MN/north-central IA which are the remains of a mesoscale convective-induced vorticity (MCV). This feature had a northeast movement and could impact central/east- central WI later this evening. The cold front is forecast to sag into southern WI tonight and pull up stationary as it become parallel to the mean flow aloft. Meanwhile, the MCV is projected by meso-models to move into central/southern WI this evening before dissipating. Have therefore placed small pops over this part of the forecast area, mainly for the evening hours. Do not anticipate any severe storms due to weak shear, however any precipitation would produce heavy rain with PW values of 1.5-2.0 inches. Min temperatures to range from around 60 degrees far north, to the upper 60s to around 70 degrees south. It is looking like Wednesday morning will be quiet with the stalled boundary to the south and the next system still over the northern Plains/Upper MS Valley. However, the boundary is progged to start lifting north as a warm front and a convective complex associated with a cold front/mid-level shortwave to sweep into the Upper MS Valley Wednesday afternoon. The air mass will destabilize over northeast WI in the afternoon with MUCAPES reaching 1.5-2.5K J/KG over central WI. 0-6km bulk shear reach 35-45 knots which is more than sufficient to support updrafts and allow for a potential of stronger storms to move into parts of the area later in the day. PW values remain very high (1.5-2.0 inches), thus damaging wind gusts and torrential downpours would be the main threats, mainly over central WI toward evening. Max temperatures on Wednesday to be in the upper 70s to lower 80s near Lake MI, lower to middle 80s north and middle to upper 80s south. .LONG TERM...Wednesday Night Through Tuesday Issued at 342 PM CDT Tue Jul 16 2019 The main concerns in the long term are the combination of heat and humidity, potential for severe storms, and possibility of excessive rainfall. Models already had consistency issues in their handling of thunderstorms on Wednesday night into Thursday. Heaviest rainfall occurs over central and east-central Wisconsin according to the 12Z NAM but the 12Z ECWMF had it mainly to our north, with another maximum to our south. Rapid mid level flow continues across the region into the weekend. This will allow temperatures to warm up quite a bit during the daytime, with the exception of any cloudy and rainy days. Friday looks to be the day that will have the highest heat index values, with some locations reaching the 100 to 105 range. A cold front is expected to pass across the region late in the weekend, bringing cooler and less humid air to the area for early next week. There are plenty of chances for storms through the weekend in the warm humid air, and also with the passing cold front. && .AVIATION...for 18Z TAF Issuance Issued at 1258 PM CDT Tue Jul 16 2019 MVFR/low-end VFR cigs will continue across the area this afternoon with a clearing trend early this evening as daytime heating wanes. There could be a few thunderstorms along a slow moving cold front over the ATW and MTW TAF sites this evening, otherwise dry conditions under VFR category to prevail for the rest of the night. Quiet weather expected for most of Wednesday with a chance of thunderstorms late in the day over central Wisconsin as a warm front approaches from the south and a cold front approaches from the west. && .GRB WATCHES/WARNINGS/ADVISORIES...

While organized severe weather is not expected, a few of these storms may produce gusty winds and heavy rain. .DAYS TWO THROUGH SEVEN...Wednesday through Tuesday A long period of heat and humidity is expected for the latter half of this week. Air temperatures well into the 80s to middle 90s, combined with humid conditions, could push afternoon heat index values well into the 90s and even into the 100 to 105 range at some locations. Drink lots of water and wear light colored clothing if you are outdoors for an extended period of time. Several rounds of thunderstorms are possible this week. Isolated severe storms are possible on Wednesday night over central, east- central and north-central Wisconsin, and across much of the area on Thursday.
