Discussion

High heat and humidity will be the rule for the next few days in the Mid-Atlantic region with very strong high pressure ridging in control. Temperatures will climb right through the 90’s on Monday and Tuesday and flirt with the 100-degree mark in some locations. The last time Philadelphia officially reached 100 degrees at the International Airport (PHL) was on July 18th, 2012. The strong ridge tends to weaken later in the weak - beginning on its northern perimeter - and this should lead to afternoon and evening showers and thunderstorms around here beginning at mid-week and that threat of PM rain likely lasts right through the weekend. There will be a reduction in temperatures later in the week as the ridge breaks down such that we’ll likely be back in the lower 80’s for highs by week’s end.
