Temperature Outlook for Winter 2018

This is the key factor in how harsh and snowy a winter could be. This outlook is nearly identical to last winter with a very high probability for warmer than normal temperatures for the southern half of the United States. Only the Northern Plains and Pacific Northwest are given a likelihood of being colder than normal. The Great Lakes are in a region of what is called 'equal chances' meaning it's statistically just as likely to be above or below normal.
