The storm going through the Dakotas is going to wind up and produce a windblown snow from eastern North Dakota into northern Minnesota and far western Ontario. Winds will be gusting over 40 mph, and the snow, which will be heavy and wet, will be plastered over everything. I think some areas will see up to 6 inches of snow with roads becoming snow covered and slick. Even the high country of western Montana and Wyoming will see heavy snows with over 6 inches in some of the higher locations.
The cold air following the storm will plunge south and east. I know some of the models have been showing snow later in the weekend across parts of the eastern Great Lakes and Northeast. I think it's a little early in the season for snow despite what the models are showing. The boundary layer temps are not cold enough yet even though the upper-level temps where the snow develops will be cold enough for snow. What happens is the snowflakes fall through a warm boundary layer and just melt into rain. Soon folks, soon it will be snow season....
The band of heavy rains should end tonight, allowing drier weather to move in.
Heavy rains associated with the upper-level low will hit the Carolinas into Virginia. Some areas could get over a foot of rain by Monday!
The heavy rains are still coming and someone is going to have up to a foot of rain and flooding.
Major problems the end of the week and weekend as another round of flooding rains occur and Joaquin could impact the mid-Atlantic.
The Northeast will be the center for flooding rains through the weekend. Joaquin could bring troubles late in the weekend.
A stormy week for the Eastern part of the country. Heavy rains will be the main issue.
