A developing snowstorm will blanket parts of the Plains and upper Midwest into the weekend, while also spreading rain through the South and East.
Low pressure will track northeastward and gain some intensity through the Midwest and into the Great Lakes Saturday into Sunday. Accumulating snow and gusty winds will occur to the north and west of where that low tracks. Rain is expected in the milder air across the South and into the East.
One of the disturbances responsible for spawning this storm already brought rain and mountain snow to the Southwest. Late Wednesday night, Phoenix picked up its first measurable rain since Aug. 20.
Current RadarThe National Weather Service has issued winter weather advisories stretching from the southern Rockies into the western Great Lakes. Winter storm watches and warnings are in effect in parts of northern Michigan and far northern Maine, where heavier snow accumulations are either possible or expected.
Winter weather alerts have also been issued in Oklahoma, Kansas and the Texas panhandle ahead of the second, more southern storm system, beginning Saturday.
Forecast
Friday
Some areas of snow are expected from parts of the central Rockies and central Plains into the western Great Lakes.
However, most areas from southeast Wisconsin and southern Lower Michigan into southern Iowa and southward may see rain during the day. A few thunderstorms, some of which might be strong, are expected from east Texas and southeast Oklahoma into Arkansas and Louisiana.
Friday night, precipitation should change to snow over much of Iowa, northwestern Missouri, much of southern and eastern Wisconsin and northern Michigan.
Winds will also increase in the Midwest as the low-pressure system gains some intensity.
Friday's ForecastSaturday
Snow will taper off in the morning in Iowa, northern Missouri, southeast Nebraska and northeast Kansas.
Snow will continue over southern Wisconsin and northern Lower Michigan. Some snow could also wrap around into parts of northern Illinois.
Gusty winds will accompany the snowfall in some of these areas, making travel challenging at times.
Some snow will also spread into parts of northern new England, primarily in northern New Hampshire and northern Maine.
Saturday night, snow will continue in northern Michigan and northern Maine.
Rain is expected in all other areas, from the Northeast and Ohio Valley into the South.
Saturday's ForecastSunday
The low-pressure system will push into eastern Canada, with only some leftover rain or snow showers in far northern Maine and possibly to the east of the eastern Great Lakes.
Attention will then turn to the South, where a new upper-level disturbance arriving in the Plains will help generate low pressure along the storm's lingering front.
Most areas in the South will see another round of rain as that low tracks eastward near the northern Gulf Coast through Sunday night.
However, there will likely be enough cold air to generate light snowfall from parts of southern Kansas and the Texas Panhandle into Oklahoma and the Ozarks of Missouri and Arkansas on Sunday. This wintry weather is expected to spread into the central and southern Appalachians Sunday night.
Sunday's ForecastMonday
The second low will push through the Southeast and East Monday, with rain in most areas from the mid-Atlantic states to Florida.
However, some snow is likely to linger in the Appalachians and possibly into interior portions of the Northeast.
Monday's ForecastSnow Forecast
In most areas, snow accumulations will be modest.
Accumulations are expected from southern Nebraska and northern Kansas into northern Michigan and northern Maine. This includes Omaha, Des Moines, and Madison.
Within that broad area of Midwest snow, there could be narrow bands of heavier totals that reach 6 inches or more. That is most probable over northern Lower Michigan, but can't be ruled out in parts of central and eastern Iowa into southern Wisconsin.
Heavier snow totals are also possible in far northern Maine.
This snow will be quite wet, and, together with stronger wind gusts, could lead to some power outages in the western Great Lakes.
The second band area of snow Saturday night and Sunday will spread totals generally less than 6 inches through southeast Colorado, northeast New Mexico, southern Kansas, the Texas Panhandle, Oklahoma and the Ozarks.
All these accumulations could lead to slippery roads, particularly any untreated bridges and overpasses and areas of hilly terrain.
Rainfall in the rest of the Midwest, South and East is forecast to be moderate, at most, with no significant flooding expected.
Rain and Snow ForecastStrong winds blowing over parts of the Great Lakes still running at levels well above average may lead to areas of lakeshore flooding along Lake Michigan's western shore this weekend.
The National Weather Service has issued lakeshore flood alerts from eastern Wisconsin to northwest Indiana, including the Chicago lakefront, as well as southern and western shores of Green Bay in northeast Wisconsin.
In these areas, parking lots and roads may flood, some beach erosion is possible, and some properties along the immediate shore may take on water.
