Sometimes I wonder how people survived in the days without A/C, fans or even wearing shorts? Esp. when the weather was even hotter? Like the 1930's when the PA state record of 111 was set in Phoenixville, in 1936. Hey, our heat index won't even come close to it this week! How did they survive that dangerous weather?
All sarcasm aside. It will be hot and humid for Tue and Wed. A cold front moves through on Thu bringing a shower or a storm, then it stalls out just to our south on Fri and through the Labor Day weekend. A new cold front will approach our area on Sunday, but it too looks to lose steam and stall out. Get used to this theme for the month of Sep. Not all fronts will stall, but it will happen several times.
This kind of pattern leads to a warm, muggy, and potentially wet days. I do not see a renewal of the pattern we had for much of the summer, but it will feel similar, and the presence of some heavy showers and storms will look similar, but the lack of flooding will be a very large difference.
Our pattern is dominated by high pressure in the east, and a trough out west. This is good for both areas. In the east, a relief from the rain. In the west a relief from the dryness and heat. In fact, some snow is likely to fall in the mountains of the NW US in the coming week. That is a big change. For us, warm and muggy will be the rule for most of the next week, as the only real hot temperatures to be found will be Tue and Wed.
