A historic winter weather week continues. Patchy freezing drizzle will redevelop late tonight and could cause some problems on roadways across our northern counties. Saturday afternoon and evening, additional light freezing rain and sleet may exacerbate these issues. 1/x
It only gets worse from there. Sunday evening, a wintry mix will develop, and as temperatures plummet a changeover to snow will occur with accumulations expected in many areas. 2/x
Travel Sunday night into Monday will be difficult if not impossible as winds increase and whip around the snow, reducing visibility. Additional power outages could be possible. 3/x

Meteorologists at 92 locations in the US and its territories and many others worldwide have launched weather balloons twice a day, every day for many decades. Here's one example of how the process typically works, made a while back by @NWSTampaBay: 2/5
Recently, a system was developed that automates the process and can be controlled remotely. @NWSFairbanks shows one off here: . There is also some additional info here: bit.ly/2SOHgF4 3/5
