Marine Weather and Tide Forecast for Bloomington, MN

DISCUSSION
Issued at 1224 PM CDT Tue May 19 2026

Current observations highlight spotty sprinkles/drizzle thanks to the lingering stratus deck. High temperatures will top out in the low to mid 50s with northwest winds gusting to 25 mph. It will feel much closer to late March than late May. Skies will gradually break up this through the evening with clearing skies likely overnight as a surface high pressure moves in. Northwest winds will turn light and variable overnight. The combination of light winds and mostly clear skies should allow our temperatures to fall into the low to mid 30s across much of western and central Minnesota. A Frost Advisory goes in effect tonight through early Wednesday morning given the likelihood of areas of frost across western and central MN. What about a Freeze Warning if my low temperature is 30? Sub- freezing temperatures are possible tonight, especially across central MN, but the residence time below freezing shouldn't be long enough to experience a proper freeze. This is why we went with a Frost Advisory versus a Freeze Warning. Temperatures should remain a few degrees warmer across E/S MN and W WI, helping prevent any meaningful frost formation. Temperatures rebound into the mid to upper 60s on Thursday as southeasterly winds set up in the return flow across the Upper Midwest.

Our attention then turns to the holiday weekend. Our next chance for any meaningful precipitation arrives Friday afternoon into Saturday morning. Precipitation is tied to a shortwave tracking along the US- CAN border. While there could be some embedded thunderstorms with this system, the general pattern doesn't appear favorable for meaningful severe weather chances. The remainder of Memorial Day weekend should be pleasant.
Temperatures rebound into the 80s Sunday and Monday with limited precipitation chances. Guidance solutions remain varied with precipitation chances Sunday/Monday, but nothing that would imply a washout or even a disruption to outdoor plans. Warmer, Summer-like temperatures will stick around for the first half of next week.
