Trick-or-treaters this Halloween will need a warm costume in parts of the eastern and central U.S., but much of the West should escape the cold temperatures.
The good news is that there isn’t precipitation in the forecast for most areas.
Here’s where the cold air will be: A strong Canadian high-pressure system will center itself over the central U.S. by Halloween. Unfortunately, this means temperatures much colder than average are expected, especially for the Plains.
Temperatures in the 20s and 30s are expected from parts of the Rockies into the Central Plains and Great Lakes. Slightly milder conditions are expected in the mid-Atlantic and Tennessee Valley into Texas, where temperatures should reach the 40s and 50s, which is also below average.
Aside from a few showers, dry conditions are expected: The same high-pressure system keeping much of the country cold will also keep it relatively dry.
A few showers are possible from parts of south Texas into portions of the Tennessee Valley and mid-Atlantic. A mix of rain and snow is possible near the Great Lakes
Besides that, cloudy conditions can be expected across parts of the West, Midwest and South.
