Snow event, then rapid melting

Time line:      
      Snow started falling right about 7:15pm Tuesday night.  Heavier snow hit at around 9pm at which point about 1 inch had accumulated.  At 1am we had 4-5 inches of snow on the ground depending on the area and elevation.  The rain started to mix in at about 2:15am Wednesday Morning but it was off and on snow and rain until about 6am.  After 6am the temperature rose sharply and all precipitation turned to 100% rain.  It also got quite breezy this morning and afternoon.


Here's the weather graph for the duration of the snow event:



Snow Melting and warmer weather is here:
       As the snow melted and temperatures warmed, even though it stopped raining at about 9am the rain gauge was measuring rain for most of the day as the snow piled in the rain gauge melted down.  Including the snow melt off, we've recorded 1.37 inches of rain so far since midnight.  More rain is on the way and it's expected to be very wet.  Land and mud slides may be a risk once again.

Overall:
Total snow accumulation at the weather station at 2am was 4.25 inches.  It begin to melt off after that time.  No freezing rain occurred in Shoreline so we only had to deal with a slushy wet mess for the morning commute hours, no ice thankfully.
