Area forecast discussion, Jun 28, 7:06 PM CDT, 3 hours 58 minutes before
Area Forecast Discussion...UPDATED National Weather Service Milwaukee/Sullivan WI 706 PM CDT Wed Jun 28 2017 .UPDATE... A tornado watch is in effect until 10 pm. We just expanded it to include the lakeshore counties from Ozaukee south because the storms look like they'll sustain themselves all the way to the lake. All modes of storms are expected this evening. The deep layer and low level shear are very strong. There is just enough CAPE to sustain these storms. Conditions are favorable for tornadoes. We are seeing mainly linear storms, but also some supercells in the vicinity. There are notches developing in the lines, so we are keeping eyes out for circulations. Very heavy rain with these storms, but there is a general southeast movement, so no flash flood warnings at this time. May need to issue urban and small stream flood advisory. The storms you see on radar are probably the only ones we'll see, but there is still a chance through just after midnight due to lingering instability and warm air advection. && .AVIATION(00Z TAFS)... Storms early in the evening. Keep an eye on radar. Very heavy rain. Strong winds are expected on leading edge of storms, hail possible, tornado possible. The storms you see on radar are probably the only ones we'll see, but there is still a chance through just after midnight due to lingering instability and warm air advection. && .PREV DISCUSSION... (Issued 342 PM CDT Wed Jun 28 2017) SHORT TERM... Tonight...Forecast Confidence is Medium. There is a round of thunderstorms across south central and southeast WI right now. These are fueled by persistent warm air advection and strong moisture transport. The ML CAPE is on the rise and storms are starting to get a little more height to them. Still not tall enough for severe. The storms moving into southeast WI actually has sunshine, so that will help sustain them as they move through. The next round of thunderstorms approaching from IA will have the potential to be severe. These should arrive in Madison around 5 to 6 pm. However, the low clouds that are hanging around all day are not helping the instability situation and these storms may just be a large multi-cell cluster by the time they reach south central WI. Time will tell. More storms could move through southern WI as late as midnight, but these have a much lower chance of being severe. Thursday through Sunday...Forecast confidence medium. A low pressure area will move across the nrn Great Lakes and Ontario, Canada for Thu-Thu nt while its trailing cold front slowly moves across srn WI. Meanwhile a shortwave trough will approach from the wsw on Thu bringing another round of convection to far srn WI Thu aft-eve. As the front drops swd into IL and Lower MI late Thu nt into Fri, another shortwave trough and wave of low pressure will track along the front bringing yet another round of convection for much of srn WI, heaviest in se WI. On Sat, wnwly flow will prevail with a weak cold front for the afternoon and evening with isolated to sct tstorm development possible. A weak ridge of high pressure will follow late Sat nt into Sun. Temps and humidity during this period will be near seasonal normals. LONG TERM...Monday through Wednesday...Forecast confidence low. The models differ on the overall evolution of the synoptic pattern and a wavering frontal boundary. Chances of showers and storms will continue with the possibility of a stationary front in the vicinity of srn WI. AVIATION(18Z TAFS)... Ceilings will gradually improve from west to east this afternoon as we get better mixing and more heating. Plan on gusty southerly winds as well. We are still expecting a couple more rounds of thunderstorms. There will be some scattered storms through late afternoon, then a larger area of storms should approach south central WI late this afternoon which could be severe. There is yet another chance for storms during the evening hours which could also be strong. MARINE... The increasing southerly winds are delayed this afternoon due to the morning showers, but they are starting to come up now. Winds and waves will remain high through much of the night. A small craft advisory is in effect. Westerly wind gusts will approach small craft advy levels Thu afternoon. BEACHES... A Beach Hazard Statement is in effect from Port Washington to Sheboygan. Breezy southerly winds and high waves will bring a high swim risk to the Sheboygan county beaches. Winds will be a bit more off shore and waves will be lower south of that area. However, a moderate swim risk covers all of southeast Wisconsin Lake Michigan beaches. && .MKX WATCHES/WARNINGS/ADVISORIES... WI...Beach Hazards Statement until 4 AM CDT Thursday for WIZ052.
