January 4 2018

Roads are covered in with snow and ice this morning. This view was in Arlington VA at 2 AM from one of my clients out treating the pavement. The best advise I can give for traveling is that not all roads are the same. Some treated will be wet but could get snow blown over. Plus its cold enough to refreeze quickly. Other roads are just covered and slick. School delays and closings are widespread.

Winds Whip Up During The Morning

‘Near’ blizzard conditions away from the beaches with blowing snow after it stops falling. 

 

Winds will increase all morning as the snow pulls away

Wind Chills Another Factor

These numbers will be similar from morning to afternoon.

Morning Radar

Doppler Radar may have trouble showing all of the fine snow flakes, but this depiction shows the heaviest snow band. This has been wobbling around the west and west side of I-83 and Baltimore. This helps prove the sharp cutoff mentioned in all the forecasts leading up to this event.

Snow Amounts

East Gets The Beast, Less West

Here is my  snow-cast from yesterday

Please note that a shift of 50 miles west could double your snow totals, while a 50 mile shift east can cut them in half or off all together.

  • A: Dusting to 2 Inches
  • B: 2 to 4 Inches
  • C: 3 to 6 inches
  • D: 6 to 12 inches

May The Flakes Be With You
