Discussion

Abnormally strong upper-level ridging continues to dominate the scene in the Northeast US and Upper Midwest and the resultant hot, humid weather around here will continue through the work week. One change, however, is that here will be an increasing shot at scattered showers and thunderstorms over the next few days and rain will be quite likely on Friday as a cool front arrives. Given the excessive humidity in the area, any rain that falls can be heavy at times. The center of this high-level ridging will retrograde westward by later this week and become centered over the interior western US. As a result of that change in positioning, the flow of air in the upper atmosphere around here will become northwesterly and this will allow for the cool frontal passage as we head into the weekend.
