Strong high pressure will spread eastward from the Plains over the next couple of days and it will be anchoring the coldest air mass of the season so far in the eastern half of the nation. High temperatures for the next several days will be way below normal for this time of year and lows late at night will not be far from the freezing mark in the northern and western suburbs. Below normal temperatures continue in the region this weekend although there will be some slight modification in temperatures.
Elsewhere, there are two large sunspot regions on a suddenly active sun and both are currently facing the Earth. One of these active regions did indeed erupt last night with an M-class solar flare and more activity is possible over the next 24 hours or so.
