Today: Rain Finally Comes to an End

The stacked low responsible for our prolonged stretch of wet and dreary weather to start November finally opens into a wave and lifts northeastward early this morning. The lower tropospheric deformation zone/surface low gradually elongates and dissipates over the region by sunset with the departure of its upper level support. The accompanying rain showers likewise wane and shift east through the day. Overall additional rainfall amounts for most locales look to be less than a tenth of an inch. Low clouds will be a bit slower to dissipate with a trailing upper tropospheric wave sliding down across the MN Arrowhead and into Wisconsin later today and tonight, keeping cyclonic flow in place into Friday afternoon.

Friday into Next Week: Drier, Seasonal Temps till Sat, Warmer Early Next Week

Large scale descent in the wake of our the upper wave will lead to clearing skies and cooler temperatures for Friday. The entire region will almost certainly (>95%) drop below freezing Friday night into Saturday morning. Users should note that, since the growing season has already ended, no Freeze Watches, Frost Advisories, or Freeze Warnings will be issued until spring.

After a northern and southern stream wave pass well to our northeast and southwest, respectively, on Sunday, heights aloft rise into the new work week. Temperatures will once again rise to above normal for this time of year, likely (70-90% per 05.01z NBM) above 60 for Monday and the upper 50s into the middle of next week. The next chance of noteworthy precipitation may not arrive until the end of next week at the earliest.
