      Unsettled weather for the second half of this week

      The deepest moisture associated with Mondayâ??s low pressure system is pulling away from the Upper Peninsula early Tuesday morning. Meanwhile, another weaker disturbance will try to drop in out of southern Canada with a mix of rain and snow Tuesday. Much of the moisture associated with that system will stay north of our area. However a mix of spotty light rain and snow is possible, mainly along the Keweenaw Peninsula Tuesday afternoon.

      Temperatures Tuesday become noticeably warmer. Highs across much of the Upper Peninsula top out in the 30s. But the warmest portions of the western U.P. could see highs in the low 40s. Meanwhile, the cooler places in the far eastern counties manage upper 20s. Indeed it seems our streak of days below freezing at the NWS office in Negaunee Township is about to come to an end!

      Temperatures stay mild Tuesday night. That means the threat for spotty, light snow/freezing drizzle which could linger over the Keweenaw Peninsula will also shift into our eastern counties this evening and overnight.

      Some of that wintry mix may linger into our Wednesday morning. But high pressure will carve out mainly sunny skies quickly enough. With temperatures topping out through the 30s for a second day, it feels more like spring across Upper Michigan!

      Our dose of spring will be short and sweet. A new low will deepen quickly as it approaches Upper Michigan out of the Plains. This will be one to watch closely over the next couple of days. As it looks now, 8-10 inches of new snow are possible over the western U.P. with perhaps six inches looking east. Admittedly, there is a small amount of uncertainty here as the timing and track of this system will play a big role on our precipitation type Thursday and Thursday night.

      Rain, snow, sleet and freezing rain are all possible, especially over southern and eastern U.P. which will be in the warm sector of Thursdayâ??s low. There may even be a limited chance for isolated thunder Thursday across the eastern half of Upper Michigan.

      By Friday, we expect gusty west to northwest winds, colder air with highs into the low teens in the west. There will also be a good amount of blowing/drifting snow, especially along our Superior shoreline and through the Keweenaw Peninsula.

      Again, the exact timing and position of any mixed precipitation Thursday into Friday is still in question. But we certainly will want to pay attention to our changing weather for the second half of the week. Cold air will return and linger over Upper Michigan at least through the end of February. It appears winter is not through with us yet.
