Issued 325 PM CDT Fri Apr 12 2024

Tonight through Saturday night:

Currently, some isolated showers have popped up in southeastern Wisconsin, with some rumbles of thunder along the line. The lowest layers of the atmosphere continue to remain drier than aloft, which may have some areas seeing more virga as opposed to rain. Northwesterly winds will continue throughout the afternoon and into the evening, before calming going into the evening. Any remaining precipitation will also taper off around the late afternoon into the evening.

Tomorrow, high pressure over the Central United States will build into southeastern Wisconsin. With this ridge, southerly winds and sunshine will help bring warmer temperatures to the area going into the afternoon hours. Locations closer to the lakeshore will remain cooler than interior Wisconsin, which will see temperatures around the mid-to-upper 60s. Weather will remain generally uneventful due to the high pressure overhead.


Issued 325 PM CDT Fri Apr 12 2024

Sunday through Friday:

To begin this period, Sunday will continue to be on the warm and dry side with a 500mb ridge sitting over much of the Midwest.
Temperatures will reach into the low to mid 70s inland while lakeside communities will be cooler with temperatures sticking around in the mid-60s. With dewpoints dropping into the lower 40s and winds nearing 10-15mph, RH values will fall into the 30% range Sunday afternoon. While we are not anticipating anything too concerning with regards to fire concerns at this point.
However, if trends hedge on the drier side, more consideration will be needed in future forecasting cycles. Monday will present similar conditions to Monday but temperatures will be a few degrees cooler but the dewpoint will be heading into the afternoon in advance of a trough exiting the Southern Plains.

As we head into the overnight hours on Monday, our main weather threat of the week will arrive. At the synoptic level a trough will exit the Southern Plains on a northeasterly track towards the Great Lakes. As it does, it'll support the cyclogenesis of a sub-990mb low east of the Rocky Mountains. Through this we will see a warm front associated with it begin to trek through the Midwest and eventually into the Great Lakes region sometime on Monday Night and into Tuesday Morning. Precipitation chances will increase as the front moves through the area. The Storm Prediction Center has placed much of our CWA under a 15% chance of severe weather. With that in mind, there will be many things that will have to be sorted out before we could potentially see any severe weather. The first being, the location of the warm front. Does it make it into Wisconsin or does it stall out south of our CWA due to an enhanced lake breeze setting up? Secondly, where does the jet streak trend to? Does it allow for the more robust storms to occur in our area or down in IL? Lastly, -this won't become apparent until Monday's severe storms are resolved, but how much instability will be available on Tuesday. The EML and associated lapse rates will be worked over somewhat on the day prior. This will result in Mid-Level Lapse Rates remaining on the lower side as of now. With all that in mind, the foundation is there for convective storms with model guidance showing dewpoints in the 58-61F range, trough just to our west, and just enough instability through the day to potentially give us some stronger/severe storms.

Regardless if we get any severe weather, we will see widespread precipitation across the entire CWA Rain should start early Tuesday and continue in some shape or form until late on Wednesday when a cold front moving through ends all precipitation. By the time it's all said and done, rainfall totals could be reaching upwards of 0.5-1.25" from Monday through Wednesday. To close out the week, cooler conditions will prevail with winds out of the NW and temperatures 10-20F cooler than it was earlier in the week.


Issued 325 PM CDT Fri Apr 12 2024

Popcorn convection and strato-cumulus has developed across southeastern Wisconsin, with some rumbles of thunder heard closer to the lake. However, drier lower layers will keep cloud ceilings VFR as the showers pass over. Afterwards, calmer winds and clearer skies expected to persist into tomorrow.


Issued 325 PM CDT Fri Apr 12 2024

The low pressure of 28.9 inches over Ontario continues to move out of the Great Lakes region, bringing with it gales of around 30-40 knots across Lake Michigan. The greatest winds remain isolated to the southern portion's eastern shore, where gales have reached as high as 45 knots. Winds still expected to calm going into the evening, but gales will remain over the upper third of Lake Michigan before subsequently dropping off.

By tomorrow afternoon, a building ridge of 30.2 over the Central United States will settle over the area, bringing with it southerly winds of around 10-15 knots. Over the lower third of the lake, there is a possibility of some gustier winds over the water and eastern nearshore, but it will be brief and taper off going into Saturday evening. A passing shortwave will shift winds back out of the north/northwest by early afternoon Sunday, with light variable winds into Monday. Gusty southerly winds expected to return by late Tuesday over the open water.
