Tonight's temperature is again 32°F, with winds of 10 mph from the West. As can be seen on the surface map, there is a cyclonic motion caused by a Low Pressure air mass centered right over Grand Rapids, MI. This probably is what's causing the apparent lack of wind there. What does not show quite as well on the unisys map is the Low in northern Minnesota. The winds on the outer edge of these two systems meet around Ironwood and what I think is Ladysmith, which is causing similar readings but for the opposite reason. We can expect the overcast skies to remain until the second Low clears out, but with no Highs in sight that could be a little while.
