Marine Weather and Tide Forecast for Spring Park, MN

DISCUSSION
Issued at 355 AM CST Sat Dec 7 2024

Low clouds have pushed well east of the area this morning, but extensive high clouds have shrouded much of the Upper Midwest.
With the upper trough from earlier in the week continuing to move out, a milder Pacific airmass is advancing in. 925 mb temps this afternoon will range from +3 to +5C across central MN and WI, to +6C to +8C across southern MN. This should translate to highs in the low to mid 40s and upper 40s to lower 50s, respectively, given the high clouds and weak sun angle. However, the ceiling is several degrees higher in the mid to upper 50s if we mix to 925 mb dry adiabatically. Records today are in the low to mid 50s.

Two disturbances will impact the central U.S. Sunday and Monday.
One will be tracking along the Canadian border, and the other over the southern High Plains will track northeast along the Ohio Valley. The northern wave would be most influential locally. However, most of the precipitation with it is expected along and north of the track across southern Canada and northern Minnesota. A small chance for rain exists across central MN Sunday, with the rest of the area remaining dry and mostly cloudy. Should be a bit cooler, but if a fair amount of sun can be experienced across southern MN, then highs there may make another run at 50. As the system departs Monday, colder air and moisture wrapping around on the backside could bring a few snow showers across central MN. Little or no accumulation is expected.

A second cold front and reinforcing shot of Arctic air will head southeast Tuesday night. Highs Wednesday will generally be in the teens. The coldest night of the season so far could be Wednesday night with lows in the 5 below to 5 above range. A warming trend and above normal temperatures will return late week as the trough exits to the east.
