SkyWarn 13 Forecast
A COMFORTABLE MIDDLE OF THE WEEK BEFORE THE HEAT GETS TURNED UP THIS WEEKEND
Areas of fog has developed this morning in the Chippewa Valley after the rain yesterday. A light northwest wind will continue through the region with partly cloudy skies transitioning to mostly cloudy at times through the afternoon in Eau Claire. In the Coulee Region the afternoon will become overcast and a few showers and storms are expected to drift by as a low pressure system passes to the south of the state. Both locations will end up seeing temps max out in the upper 70′s. Skies will become clear overnight as high pressure begins to establish itself across the Upper Midwest.
Thursday will kick off with temps in the upper 50′s once again, but thanks to more abundant sunshine, the morning will warm quickly. Temperatures across Western Wisconsin are expected to return to average if not a degree or two above. Humidity may become noticeable again, but the air will still have a pleasant feel. Later this week the upper level pattern will remain zonal but the jet stream will push a bit farther north again, allowing higher heat and humidity to return. Southerly flow will play a major role in this as it greatly increases into Friday. This is when that sticky feel may return to the air, along with highs in the upper 80′s and perhaps 90 in a few locations.
The highest heat this week will come on Saturday as plenty of sunshine is expected during the day, along with that strong southerly flow of air. Highs are likely to be between 90-95 depending on where you are across Western Wisconsin. Humidity will add a very uncomfortable feel to the air as dew points may reach oppressive (75F or higher) levels across the state. The heat index may very well be between 100-105F across the Chippewa Valley and surrounding areas. As we head into the evening we’ll be watching the potential development and impact of thunderstorms, possibly in the form of an MCS. As with any convection, the details are unknown, but the threat appears to be there. We’ll be watching this one closely for you guys. The good news is that improvement already begins to take place on Sunday. Skies are expected to remain partly cloudy and temperatures will begin to slowly drop as a low pressure system over Canada pushes cooler air into the Upper Midwest region. We’re expecting this drop in temperatures to continue into the start of the new week as well, though storm chances may be on the rise heading into those first few days as well.
