Issued at 657 PM CDT Wed May 22 2024 The chance for lightning is near zero the rest of the evening as thunderstorm chances are quickly diminishing. Showers will also continue to decrease in coverage this evening and westerly winds will become light and out of the south. && .DISCUSSION... Issued at 244 PM CDT Wed May 22 2024 We`re enjoying a little break in the active weather of the past two days as yesterday`s system spins to the north over Ontario. Rainfall totals across the area generally range from 2-4 inches since Monday, with lower totals out west. Breezy west/northwest flow is keeping temperatures in the low to mid 60s early this afternoon with a nice diurnal Cu field across the area. A few isolated showers have popped up over the last hour or so across central Minnesota and western Wisconsin with the 500mb trough still lingering in the area. These showers will remain fairly isolated in nature, but may produce some small hail and gusty winds before diminishing by sunset. Southerly flow returns for tomorrow ahead of a low over the Dakotas, allowing for WAA and moisture to advect back into the region. Temperatures will make a run at 80 ahead of the cold front, but the timing of the frontal passage looks to be late Thursday night, missing the best window of instability. Still, a few stronger storms with hail and gusty winds are possible tomorrow night into early Friday from western into central Minnesota with most thunder potential decreasing by the time the line reaches eastern Minnesota and western Wisconsin Friday morning. QPF amounts are on the order of a quarter to a half inch, with locally higher amounts possible. Heading into the holiday weekend, temperatures look to be in the upper 60s to low 70s with daily slight chances for showers as an upper low is parked north of us. This weekend does not look to be a washout by any means at this point, with very low QPF amounts overall. A stronger embedded wave looks to swing through on Sunday, which will lead to the highest chances for scattered showers and storms, particularly across the southern half of the forecast area. It`s not until sometime Tuesday that this low finally moves out and we see slightly warmer temperatures and drier conditions return by the middle of next week. && .AVIATION /00Z TAFS THROUGH 00Z FRIDAY/... Issued at 651 PM CDT Wed May 22 2024 VFR conditions throughout. Showers will dissipate this evening and wind gusts will decrease toward sunset.
