Good synopsis of the upcoming period from Mount Holly-
A typical summer pattern develops for the long term as a Bermuda High becomes established offshore and a slow moving trough develops over the Great Lakes. This is a classic southwest flow regime which is likely to be in place for at least several days beginning the end of this week and heading into next week. The result will be a transition from the dry and cooler weather during the middle of this week to a sustained warm and humid pattern, especially by the time we get to the weekend. From Saturday onward, we will mostly be looking at highs in the mid 80s to near 90. This is nothing atypical for the season, but combined with the increasing humidity, we may flirt with Heat Advisory levels at times during the period. Rain chances in this pattern are quite uncertain at the moment. It will depend heavily on how fast a cold front to the west approaches as Great Lakes troughing slowly moves eastward and/or starts to lift out. Model guidance has a spread of several days on when this front will move through, or if it even will at all as opposed to just washing out. My general thinking is that rain chances will gradually increase from Saturday onward, especially to the west, but that overall there will be a lot of dry hours through the period.
