Back to the 1950s to achieve record highs. Rain by Thursday
The quick summary of our upcoming weather is that we will have three more very mild days turning into a rainy Thursday. A cooler weekend will follow. Here’s the forecast from the National Weather Service office in the Twin Cities:
The mild Pacific air heading our way that has drenched California will bring temperatures to record highs in snow-free southern Minnesota.
High temperatures on Tuesday are expected to range from the upper 30s and lower 40s in the north, where there is snow cover, to the low and middle 50s in the southern half of the state. The Twin Cities should rise to around 54 and set a new record for this date, surpassing the old record of 51.
This southwesterly flow will also bring mid-level moisture, so look for increasing clouds again.

More of the same for Wednesday
Wednesday will be the warmest day of the week as moderate air spreads north. Highs will likely range from the low 40s north to mid 50s south. The Twin Cities’ projected high of 55 degrees would break the old high temperature record of 53 degrees.
Rain on Wednesday and Thursday night
Rain from the California storm will cross the Rocky Mountains and lose some moisture and some of its dynamics on its way toward Minnesota. Rain showers are expected to reach Minnesota on Wednesday night and continue in scattered showers on Thursday.
Rainfall totals could range from a quarter to a half inch across most of the state. Parts of northern Minnesota could get more than a half-inch while the southeast corner could get less than a quarter-inch.
This spring-like storm will be mainly rain. But cold air mixing at its rear will likely turn some rain into wet snow Thursday night and Friday, especially in northern and central Minnesota. Melt accumulations are possible in the northern half of the state.
It looks like the best chance for an inch or so of snow by 6 a.m. Friday will be in the northwest part of the state.
Cooler for the weekend and into next week
The weekend and into next week will be cooler, but still warmer than normal.
