Frost is possible away from Lake Michigan late tonight. - Temperatures will gradually warm through the end of next week, with continued dry conditions. && .UPDATE... Issued 952 AM CDT Sun Oct 6 2024 The secondary frontal boundary denoted by the northwesterly winds and slight temperature gradient is draped across central Wisconsin late this morning will continue moving east today. The west to northwest winds will continue to be gusty until high pressure begins to build into the Great Lakes Region Monday. With the colder and drier air mass moving in behind this secondary frontal boundary and clear skies overnight there will be a potential for some frost to develop. Frost is expected to be patchy, confined mostly to low lying and shelter areas away from Lake Michigan. The forecast is still on track. Patterson && .SHORT TERM... Issued 341 AM CDT Sun Oct 6 2024 Today and Tonight: Gusty westerly winds are expected today in the wake of a potent low pressure system. The low tracked across Ontario overnight and will continue to progress northeast today. There is a secondary cold front pushing into northwest WI early this morning, and this will give us an extra push of gusty winds in southern WI this afternoon. High pressure will wedge into the Upper Midwest later today and tonight. Gusts will be in the 25 to 30 mph range during peak daylight and mixing hours today. Temperatures were at their highest at midnight, prior to the frontal passage, and are falling into the upper 50s early this morning. They are only expected to recover into the mid 60s this afternoon under mostly sunny skies, except around 70 in far southeast WI. Dewpoints should be in the mid to upper 30s today. Winds will become light late tonight under clear skies. With a strong surface inversion and cooler air mass overhead, low temperatures should dip into the mid to upper 30s for inland areas. Patchy frost is in the forecast, targeted for the typical low spots. Cronce && .LONG TERM... Issued 341 AM CDT Sun Oct 6 2024 Monday through Saturday: Surface high pressure will sit over the Midwest and Upper Great Lakes through Thursday, giving us a dry forecast. Temperatures will gradually warm through the week. There will be a frost potential again Monday night and Tuesday night for inland areas/low spots. The main concern each day will be how low dewpoints and hence RH values will be each afternoon. Vegetation/fuels are drying up and we will have an increasing fire weather concern for the next time we have windier conditions. Cronce && .AVIATION... Issued 952 AM CDT Sun Oct 6 2024 VFR conditions with gusty winds are expected today. The VFR conditions under mostly clear skies will continue through mid next week. Gusty west to northwest winds are expected through late this afternoon behind the passage of a secondary cold front. Winds will begin to weak overnight ahead of an approaching high pressure system. Light westerly winds are expected through Monday night. Skies will be mostly clear with a small chance for some mid level clouds around 4-6kft to move into central Wisconsin early this afternoon. These mid level clouds are expected to be scattered and diminish as the move through the area. Patterson && .MARINE... Issued 341 AM CDT Sun Oct 6 2024 The Gale Warning will expire as planned at 4 AM. We still have a sliver of the northeast part of Lake Michigan with southerly gusts and the gale potential. Otherwise, winds are becoming west to northwest in the wake of a cold front this morning. Gusts up to 30 kt are expected today. A secondary cold front will track across the north half of the lake this afternoon and there is a potential for a few gale force gusts. Look for winds to diminish overnight through Monday as high pressure expands into the region. Winds will remain light through much of the week, as high pressure lingers across the Midwest.
