Showers and thunderstorms seem likely through the afternoon hours on Saturday. Highs will warm into the middle and upper 70s with winds out of the south around 5-15 mph. We’ll be keeping a close eye on a frontal boundary that will track through the viewing area late Saturday afternoon and early evening.
There is disagreement between models of the placement and timing for thunderstorm development Saturday. One scenario has the frontal boundary stalling out over central Minnesota and western Wisconsin. This would be the best case scenario for showers and thunderstorms for the viewing area Saturday afternoon & evening.
Other guidance suggests the frontal boundary moving to the south-southwest of Rochester and the viewing area keeping thunderstorm activity to the west and southwest of Mason City. If this were to happen, thunderstorm chances for Rochester would be limited.
Right now, expect scattered showers and thunderstorms during the late afternoon and early evening hours mainly after 3 p.m for Saturday. Some of these storms could be on the strong side with gusty winds and small hail.
As we move into Father’s Day, temperatures will be on the cool side. Highs will struggle Sunday afternoon as they only warm into the middle and upper 60s with overcast skies. Hopefully we’ll get a couple breaks in the clouds to get some sunshine late in the afternoon. An isolated shower can’t be ruled out early in the morning.
Comfortable conditions are expected as we head into next week with highs in the middle 70s Monday through Thursday. We’ll have dry conditions for Monday and Tuesday before rain chances return to the forecast Wednesday.
