  Snow and ice Wednesday Night

Posted: 12/08/2008 05:15:00 PM

This has been overlooked to some extent by many people, because of the timing of the coastal low.

After temperatures hit the 50's on Wednesday, a strong cold front will punch through the warmth, rapidly ushering in much cooler temperatures. In fact, surface temperatures could fall 15 to 20 degrees in the matter of a couple hours with the frontal passage Wednesday evening. With some overrunning continuing in the mid levels, precipitation will continue after the frontal passage. Surface temperatures could fall below freezing by midnight, allowing rain to change to freezing rain, then eventually sleet and then snow. Advisory level snow and ice accumulation is a possibiliy through Thursday morning.

So to review:
  • Light snow/sleet possible tomorrow
  • Snow/icing possible Thursday morning
  • Coastal storm sometime between Thursday evening and Saturday morning
