NWS Milwaukee, WI wrote its last area forecast discussion before the first event at Jul 16, 9:34 AM CST, 2 hours 51 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 1034 AM CDT Tue Jul 16 2024 .KEY MESSAGES... - Active stretch of weather featuring daily chances for strong to severe storms has ended, though several days of heavy rains have resulted in elevated water levels on area rivers. Multiple sites expected to remain in flood stage through at least this weekend. - A few patches of fog possible through daybreak across the west. - Isolated to widely scattered showers possible during the afternoon hours today & tomorrow. - Pleasant weather prevails from late week through the beginning of the weekend, with zero precipitation and low humidity expected. - Next window of opportunity for showers and storms arrives late Sunday through the beginning of next week. && .UPDATE... Issued 1030 AM CDT Tue Jul 16 2024 Slight chances (~15%) for a brief shower today especially across SE WI, particularly this morning into the early afternoon with the front pushing through the area. While storms are by no means expected we cannot rule out a very weak and brief storm (<10%). Into the afternoon another weak boundary may slide through but showers based on latest CAMs seem less likely than even this morning though perhaps a bit more areally broad chances (10%). Kuroski && .SHORT TERM... Issued 357 AM CDT Tue Jul 16 2024 Today through Wednesday: Synopsis/Mesoanalysis: Last evening's strong to severe storms have pushed well southeast of the region early this morning, with satellite showing a well-defined MCV over the Lower Peninsula of Michigan and clearing skies across southern Wisconsin. A cold front is beginning to approach the region from the northwest, with 3 AM analysis placing the boundary along an approximate Green Bay to La Crosse line. Attempts at shower and thundershower development are evident along/ahead of the feature, with individual cells struggling to maintain as they encounter a worked over air mass in southeastern Wisconsin, in addition to subsidence along the back side of the Lower MI MCV. The cold front will continue to work through the region this morning, exiting to the south and east following the lunch hour. West-northwest winds will become established in the wake of the departed front, allowing a much drier air mass to work into the area through the remainder of the short term period. Currently evident in water vapor imagery over the Manitoba-Ontario border, an upper trough will pivot southeast into central Great Lakes through Wednesday. DPVA embedded within said upper trough could help to focus widely scattered shower & thundershower development both this afternoon and Wednesday. Rest Of Overnight: Anticipate that repetitive, but largely unsuccessful attempts at shower development will continue through daybreak. Apart from some light precip, activity will be of negligible impact. Already being hinted at in observations from the Wisconsin River Valley, some patchy fog is possible through daybreak, with most fog concentrating along and west of Interstate 39. Widespread dense fog isn't expected. Today: Will be monitoring obs trends as the above mentioned cold front passes through the region. The vast majority of 00 & 06Z CAMs depict a dry frontal passage, though the 00Z run of the HRRR did hint at isolated shower & thundershower development in southeastern Wisconsin during the late morning and early afternoon. Given a lack of support for this solution in other guidance, as well as more recent runs of the HRRR itself, have maintained a dry forecast along and ahead of the boundary. Will nevertheless monitor trends and make adjustments to the forecast if necessary. Do expect that isolated to widely scattered showers & thundershowers will develop over north- central Wisconsin this afternoon as the leading edge of the upper low currently along the Manitoba-Ontario border pushes into the state. A few of said thundershowers could clip our northeastern counties, with the potential being accounted for in the overnight update. Apart from some claps of thunder & a few wind gusts in the 20-30 MPH range, no impacts are anticipated in this afternoon's thundershowers. Wednesday: Noticeably drier air will be in place across the region, leading to very pleasant conditions. Additional, widely scattered shower and thundershower development can't be completely ruled out during the afternoon hours with upper low pressure still in the vicinity. Negligible impacts are expected in any potential thundershower development. Quigley && .LONG TERM... Issued 357 AM CDT Tue Jul 16 2024 Wednesday night through Monday: Synopsis: Post-frontal high pressure will become entrenched across the western Great Lakes by Thursday, with global ensemble guidance suggesting continued reinforcement of the feature through late week and the beginning of the weekend. The beginning of the long term period will thus be marked by light and variable surface winds, partly cloudy to mostly sunny skies, and precip-free conditions. Temporarily flattened by the upper low passing through the central Great Lakes during the short term, subtropical ridging will amplify once more over western portions of the continent through the end of this week. Global ensembles depict an upper disturbance pivoting around the northeast side of the amplifying ridge on Friday, bringing a return of QPF signals to the Central Plains. The disturbance is likely to stagnate over the Missouri Valley on Saturday, prior to gradually working toward the Upper Mississippi Valley from Sunday through the end of the period. Chances for showers and thunderstorms thus return to the forecast by the beginning of next week. Sunday Through Tuesday: Shower and thunderstorm chances return to the forecast as upper forcing increases across the region. Specific timing details on storms remain murky, making it difficult to speculate on any potential hazards at this time. Quigley && .AVIATION... Issued 1030 AM CDT Tue Jul 16 2024 With the front coming through this morning we have seen some MVFR/IFR CIGS across southern WI. These lower CIGS have largely left central WI with mostly far southern WI seeing the lower CIGS and will continue to do so into the early afternoon before they dissipate/push out with the front departing. Slight chances (~15%) for a shower with the departing front particularly for southeast WI. Light northwest flow behind the front though a lake breeze circulation will likely bring some easterly flow near the lake by the early afternoon. Additional slight chance for a shower in the afternoon to early evening with another boundary pushing through but models indicate far more broadly isolated chances. Clearing should be expected into tonight. Kuroski && .MARINE... Issued 357 AM CDT Tue Jul 16 2024 Widespread strong to severe thunderstorms have pushed east of the southern third of the lake early this morning. Scattered showers and storms remain in-progress along an approaching cold front over the central open waters, and are expected to persist through daybreak. Said storms are not expected to be severe, though a few storms could produce small hail wind gusts between 30 and 35 knots. Radar trends will be monitored through sunrise, with marine weather statements and/or special marine warnings being issued if conditions warrant. Winds will turn northwesterly across the open waters today as the aforementioned cold front departs. Gusts to 15 knots are possible through sunset. Additional, widely scattered showers and thundershowers are possible this afternoon and Wednesday, with no severe weather impacts anticipated. Winds will become light and variable through late week as high pressure of 1020 mb builds in from the Great Plains. Quigley && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
