High pressure center is becoming reestablished over southern Quebec this morning and ridges southwestward all the way into Texas. The center of the high will only move to eastern Maine by Sunday evening, and though weakening a little, will remain virtually in the same place through Monday evening. The fact that the surface ridge will remain nosed back to the southwest all the way to the Gulf Coast through at least midweek and probably through the end of the week means any upper level features coming eastward will not have any deep southerly flow to draw up moisture from the Gulf. So we don’t see any significant rain chances for us in the forecast period. Meanwhile, a weak upper level trough that has its northern part sliding off to our east early this morning. The southern part of the energy in this trough is closing off over the Southeast today. We will see a similar set during the middle of the upcoming week.
Energy coming into the Pacific Northwest later today and tonight with what will be the first main player in the parade of rainy weather systems coming for the Northwest through midweek, will translate eastward
and stretch from the Midwest and western Great Lakes to the lower Mississippi Valley by the end of the day Tuesday. Still, Thanksgiving travel for most of the East Coast will be under sunny and dry conditions with temperatures heading toward 60 degrees.
