Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 342 AM CDT WED JUL 27 2016 .TODAY AND TONIGHT...Forecast Confidence Medium Weak short wave energy helping to drive a small pocket of convection in northern WI riding convergence along a weak surface trough/cool front, with overall forcing for ascent aided by upper divergence in the right rear quadrant of an upper jet max tracking north of the upper Great Lakes. The MCS in Nebraska is riding on the nose of the stronger low-level jet winds and 850 mb warm air advection, with the eastern Dakotas/western Minnesota convection on the leading edge of a weaker branch of the LLJ but within a pocket of better 700 mb RH and a 700 mb speed max that tracks across northern WI later today. All are within the better precipitable water channel arcing up and around the surface to 925 mb ridging over the area that models show will be slowly suppressed to the south with the approach of the short wave, allowing the cold front/surface trough and associated precipitation to sag towards and into southern WI later today. Will slowly increase PoPs from north to south, beginning this morning in the far north to acknowledge possibility in the GFS and some of the hi-res models of a weak mid-level trough sagging into the area. Best chances for showers and storms come with the passage of the short wave trough and associated surface wave late this afternoon and tonight. Will have the highest PoPs with the stronger frontogenetic response across the northern half of the CWA tonight. Will see high temperatures reached early in the afternoon with increasing clouds and developing lake breeze halting the temp rise. Looking at mid-upper 60s for overnight lows. .THURSDAY AND FRIDAY...Forecast Confidence...Medium A wave and weak surface front is expected to kick off showers and storms on Thursday. Best chance is in the southwest toward the better instability. Some moisture is expected to linger Friday, particulary toward the southern forecast area. Overall though, not seeing much in the way of forcing, so kept pops on the low end and confined to the southern half of the forecast area. With a good amount of clouds likely, especially Thursday, expecting high temps within a couple degrees of normal in the upper 70s. .SATURDAY THROUGH TUESDAY...Forecast Confidence...Medium Looks mainly dry for the weekend under high pressure. Models suggesting a weak wave may kick off a few storms Sat, so kept some low pops. Could see a few storms via another weak wave or two early next week, so maintained low end pops. Should see near normal temps for the weekend, warming up a few degrees above normal for Mon/Tue. && .AVIATION/12Z TAFS/... Again expect any patchy MVFR fog, with IFR in the Wisconsin River Valley, to dissipate within a couple of hours after sunrise. Looking for VFR conditions and light winds through most of the day, with clouds and shower and thunderstorm chances increasing from north to south during the day. Best chances for thunder will be tonight as a surface low and cold front sag through the forecast area. Looking for MVFR cigs/vsbys with the showers/storms. && .MARINE... Looking for light west winds to back around to the south ahead of approaching surface low pressure and a trailing cold front. Bringing a slight chance of showers and thunderstorms to the northern zones this morning for the possibility of a weak trough sagging in from the north, with the better chances coming tonight for the entire nearshore. Winds turn northeast as the cold front drops through tonight behind the low. Winds and waves will approach but remain below small craft advisory levels Thursday and Thursday evening. && .MKX Watches/Warnings/Advisories... WI...None. LM...None. && TODAY/TONIGHT AND AVIATION/MARINE...REM Thursday THROUGH Tuesday...DDV
