Zonal flow will prevail through Wednesday with continued above average high temperatures ranging from the mid 60s F in the north to mid 70s F in the south. Surface low pressure over Canada will move into the Hudson Bay region Wednesday bringing in high pressure and cooler temperatures behind it by Thursday morning. From Thursday through the weekend, seasonable temperatures with highs in the mid 50s to low 60s F and lows in the mid 30s to mid 40s F are expected.
The next chance for precipitation is Saturday as a 500 mb wave from Montana moves southeast. Atmospheric lift and southerly winds advecting in moisture will be enough to bring 20-50% precipitation chances with the highest chances being in Northwest Minnesota. This event is expected to be minor with a 10-40% chance of getting greater than 0.25 inches of rain. High pressure moving in behind the Saturday system is expected to bring cooler overnight lows Sunday and Monday with temperatures in the 30s F. Monday morning looks the coolest, though the chance for a freeze remains low (0-30%) for much of region.
As we move into next week, especially Tuesday, ensemble systems are generally indicating that above average heights will return to the region bringing above average temperatures. From the Red River Valley and west, there is a 30-60% chance of seeing a high temperature of 70 F or greater Tuesday. Dry conditions are also favored for next week.
