Friday’s inauguration of Donald Trump as the 45th president of the United States will take place on the steps of the west front of the Capitol at noon and it looks like a close call in terms of wet weather. Here in Maine, clouds will break for sunshine, temperatures will be in the upper 30s, not much colder than Washington where rain is in the forecast. A warm front will push northward through Virginia and toward Maryland, bringing clouds and a band of showers with steady rain along its northern flank.
