As colder air seeps in from the north and west, a swath of snow and wintry mix will extend northeastward causing slippery travel from part of the Central states to New England prior to the weekend.
A series of storms will roll out from the Southwest through next week with multiple rounds of snow and ice.
One of these storms Friday and Friday night will spread snow and ice along a swath reaching along the I-70 corridor from Missouri to southwestern Pennsylvania and over part of the I-80 and I-90 corridors from Indiana to northern Ohio, northern Pennsylvania and upstate New York.
The snow hit the Central states first on Thursday and will expand into the central Appalachians Friday and then parts of New England Friday night.
According to Expert Senior Meteorologist Henry Margusity, "With the amount of moisture available to this system and the energy release from a pronounced temperature contrast, localized bursts of very heavy snow are possible."
Within this zone, a general 1 to 6 inches of snow is forecast with local amounts up to 10 inches possible. Much of the snow will fall in only a few hours.
The cities forecast to receive accumulating snow include Tulsa, Okla., St. Louis, Indianapolis, Columbus, Ohio, Pittsburgh and Albany, N.Y.
A narrow zone of ice is likely to overlap and occur south of the accumulating snow area. A delay in or a more shallow push of cold air could mean the difference between rain, significant ice and accumulating snow in some communities.
The worst of the ice storm is expected to focus from central Kentucky to northeastern Texas. Enough ice can accumulate on trees and utility lines in these areas to cause blocked roads and regional power outages for days.
Mostly rain is forecast to fall over the I-95 corridor from Washington, D.C., to Philadelphia and New York City as the first of the storms slices northeastward Friday into Saturday. However, some wet snow and sleet can mix in at the tail end. In Boston, enough snow and sleet can fall to coat roads late Friday night into Saturday morning.
Another storm in the series will cause snow, ice and rain to reload over the South Central states this weekend before rolling toward the Northeast. That storm is likely to bring most significant snow, ice and slippery travel to the I-95 Northeast cities.
Following a wet start to the week, drier, more seasonable weather will remain across the Pittsburgh area into the weekend.
A new moon will allow for the perfect background for the Orionid Meteor Shower, set to peak on Tuesday Oct. 21 and into the morning of Oct. 22.
Cars were swallowed by rushing floodwaters that diced through streets in the Canary Islands, Spain, over the weekend.
Storms, including Ana, are lining up over the northern Pacific, en route to the northwestern United States and British Columbia.
Attention in the tropics will turn to the swath from southeastern Mexico to Cuba and Florida, where a new tropical system may form late this week.
After impacting Bermuda and Newfoundland, Gonzalo will bring rain and damaging wind gusts to Europe early this week.
