TONIGHT: Expect cloudy skies and a 60% chance of scattered showers and storms with an east wind at 5-15mph. Lows will be around 58º.
FRIDAY: The jetstream is in a ridge pattern over the Northland, but is hovering right over our region. This pattern will leave us with mostly cloudy to cloudy skies throughout the day. There will be an east wind at 4-8mph with highs near 70º. Chance of showers and thunder is around 30%.
SATURDAY: A trough in the jetstream digs south over the Rocky Mountain States. A low pressure system strengthens over Colorado. But the ridge pattern holds right over the Northland. But we still can't rule out a 30% chance of storms. Lows will be in the upper 50s and highs in the mid 70s.
SUNDAY: The trough to our west in the jet swings east bringing the strong low closer. The best chance of showers and storms is north of the Twin Ports at 60%. To the south expect a 40% chance. Heavy rain and strong thunderstorms are possible with this low. Lows are in the upper 50s and highs are in the upper 70s with cloudy to mostly cloudy skies.
MONDAY:The low moves north and we have a cold front push toward the area. But high pressure in South Dakota should inhibit most storm development. Still, with a cold front in the neighborhood we can't rule out a 20% chance of a storm or two. Lows are in the low 60s and highs near 77º with mostly cloudy to partly cloudy skies.
