High pressure will continue to bring a fair amount of reasonable weather to much of the United States during the next few days. However a cold Arctic blast is set to sweep down from the north across many central areas bringing some wintry weather to some areas in the next couple of days or so.
Starting off with the Midwest then and that cold air makes its appearance today across the northern Plains today before pushing on through the Great Lakes, the Ohio Valley, the Mississippi Valley and central Plains during tonight and tomorrow. Ahead of the cold front bringing the cold air, some light rain showers are possible in northeast Minnesota, northern Wisconsin and northern Michigan. Meanwhile rain showers will spread across the lower Great Lakes, while rain showers will turn increasingly to snow showers over northern Michigan and northern Wisconsin once the front has passed. Temperatures will range from the upper 30s and 40s from North Dakota towards central Michigan to the 60s across Kansas, Missouri and the lower Ohio Valley.
Over the Northeast today and conditions will be mostly fine and dry across the region with temperatures cooling off after the recent warmth. Top temperatures will generally be in the upper 40s and 50s, except for lower 60s across parts of Virginia. Much colder conditions will develop over the weekend as that Arctic blast moves in from the northwest.
For the South and much of the region will enjoy a mostly dry and fine day, but a few showers and thunderstorms are possible over northern Florida, eastern North Carolina and central Texas. Temperatures will be cooler than recently for many with highs in the 60's and 70's but towards the south highs in the 80's are still possible.
Finally the West and another Pacific storm arrives over the Northwest today bringing outbreaks of rain and mountain snow, but for the rest of the region it should remain mostly fine and dry. Top temperatures will range from the 50s and 60s across Washington, northern Oregon, Wyoming and northeast Colorado to the 70's for most other parts apart from the Desert Southwest where the 80's and low 90's are expected.
