KEY MESSAGES

- Much warmer temperatures are forecasted over the weekend. A more unsettled weather pattern develops late Saturday into early next week, with several chances for rain and even a few thunderstorms.

..Rain and thunderstorm chances this weekend

A narrow corridor of elevated instability with potential for values in the 500-1200 J/KG range Saturday night into Sunday (mainly in west central MN) may correlated with a LLJ/WAA and effective shear 30-40kt to support elevated embedded strong or even marginally severe thunderstorms as areas of rain showers track to through the region. Hail to 1" would be the main threats in this pattern at this time, with instability/mid level lapse rates marginal and the instability corridor generally narrower in nature. There is a much smaller window Sunday afternoon for surface based convection, which could support higher impacts, but is even more uncertain due to how fast the system will be moving through. As any rain or thunderstorms should remain progressive, there is currently not a signal for heavier rain totals (1"+) that would raise excessive runoff concerns with frozen ground/melting snow.
