Winter weather battered the United States from coast to coast on Thursday as a series of storms expected to last for days mixed with an Arctic air mass to bring snow and freezing rain as far south as Texas, where six people died in a multi-vehicle pileup.
The period of steady icy precipitation may be brief, only lasting until 4 or 5 p.m., but patchy freezing drizzle may linger well after that. This storm has the potential to affect both the Tuesday morning and evening commutes.
A somewhat subjective rating of the day's weather, on a scale of 0 to 10. This looks like mainly a freezing rain event but some sleet and snow could also mix in.
Today: Intermittent sleet and freezing rain.
Tonight: Freezing rain tapers to patchy freezing drizzle, ending late. The second half of Sunday and most of Monday should be tranquil as well and have highs in the low 30s.
Hopefully you're a fan of clouds and wintry weather. Some light icing could create some slick spots on the roads.

Tomorrow (Sunday): Any lingering freezing drizzle ends early with temperatures rising above freezing between midmorning and noon.
FRIDAY: Mostly cloudy. Highs around 40. Another storm system approaches late Monday night, but is really a Tuesday system with snow likely.
There's quite a few deliveries that will be happening for Valentine's Day and the good news is that the snow will not pile up.
When I write about the possibility of snow or rain it is just that - a possibility.
