Overview: Milwaukee’s Fourth of July is warm and humid with a chance of afternoon thunderstorms. Sunday through Tuesday brings pleasant weather with highs near 80 before Wednesday’s heat and storm chances.
Today: Another hot and humid day will be in store for the Fouthth of July over the Milwaukee area. Temperatures will be rising through the 70s during the morning hours accompanied by a northeast wind around 8 mph. Also dew points will be in the sticky 70s which could cause some morning fog close to Lake Michigan. Early peaks of sun will burn any fog off by mid-morning. Partly cloudy skies will fill in over Milwaukee as temperatures reach the low-80s by the afternoon paired with dew points in the low 70s and breezy east winds around 10 mph. A 40% chance of thunderstorms will exist in the late afternoon for Milwaukee. These storms will be quick movers with only a tenth to a quarter of an inch expected, although locally higher amounts are possible with any thunderstorm. Things will dry out during the evening as temperatures and dew points will drop back into the mid-60s for firework displays, however overcast skies hang around.
Overnight: Skies will remain overcast overnight with winds becoming light out of the northeast. Temperatures will relax into the mid-60s with dew points holding steady.
Tomorrow: On Sunday, a little relief from the intense heat and humidity arrives. Temperatures will rise into the low-70s during the morning hours with winds out of the north around 6 mph. Overcast skies will dominate over the Milwaukee area which could produce an isolated shower, but only a 20% chance will exist until noon. Pesky mid-level clouds with peaks of sunshine will persist through the afternoon as high temperatures reach the upper 70s. Winds then will turn to the west. Dew points during the day hang in the low-60s which will feel a little sticky, but not as oppressive as it has been. Clouds begin to break by the evening which will mean clear skies during the overnight hours. Temperatures slide down into the low-60s with winds turning to the northwest around 8 mph.
Monday: Monday and Tuesday will provide a nice start to the week, but storm chances and high heat and humidity return by midweek. Temperatures will reach the upper 70s Monday with north winds around 6 mph under partly sunny skies thanks to a weak high-pressure system sitting off to the west. Overnight, lows will sink into the low-60s as winds shift slightly to the north and ease to around 5 mph under clear skies.
Extended: Tuesday will be more of the same as the high-pressure system hangs over Wisconsin. Temperatures will be a little warmer with highs topping out around 80 by the afternoon. Winds will be out of the north in the morning but swing to the east by the afternoon with speeds around 5 mph. Temperatures fall into the mid-60s overnight as winds turn to the southwest with speeds staying consistent. The weak high-pressure system will start to move off to the east overnight to make way for Milwaukee’s next weather maker arriving Wednesday night. Mostly sunny skies will start out on Wednesday, but clouds will quickly increase by the late afternoon ahead of a cold front. Temperatures will reach the mid-80s accompanied by southwest winds around 6 mph which will push dew points back near 70 by the evening. A cold front approaching from the northwest will move in after midnight. This front could materialize a line of showers and heavy thunderstorms. At this point, it is too early to know if there will be any severe weather with this system, but with dew points in the 70s and temperatures in the mid-80s during the day would favor severe weather. Furthermore, temperatures will only make it down to upper 60s overnight Wednesday with winds from the south around 10 mph.
