Snow will spread north across the region overnight. Once snow begins, it will likely last 2 to 4 hours at any one given location. pic.twitter.com/tnUlUQuktZ

Snow will spread into the area during the overnight hours. Snow will then transition to freezing drizzle during the morning hours, and this will make for a messy Wednesday morning commute. pic.twitter.com/7QwelsNNCf

Here is a look at the expected precipitation type for several locations across the area this late tonight through Wednesday. For a detailed forecast for your specific location, please visit https://t.co/nBzIfSe28p and enter your location. pic.twitter.com/HySUswn31t

An aircraft reached a 801-mph ground speed while flying over Pennsylvania Monday night. That's because it was aided by a 200-plus mph tailwind in the jet stream: https://t.co/HB6y9sBLRp pic.twitter.com/heYg6t042s

Lots of people will be impacted by #WinterStormPetra and not just the #snow. Heavy #rain to the south could cause #flooding.

Threat of #flooding increases midweek in parts of the South, Ohio Valley as multiple rounds of rain are expected into this weekend: https://t.co/pBChleuCWJ pic.twitter.com/QSUlDj6983

Wash, rinse, repeat. The latest wintry mess of #snow and #ice, #WinterStormPetra, arrives in the Plains today, then spreads to the Midwest and East tonight and Wednesday. https://t.co/8ssX12lsHA pic.twitter.com/gVFzwXi7Gj
