But what about these fronts stalling near the coast, something we really did not see at least in the month of July in summers like 1991, 1993, 1999, 2002, etc (basically the summers with the longest heatwaves since 1953.)
From what I remember of 1993 and 1999 and 2002 especially, the fronts always died out before they made it into our region (at least in July.) This enabled us to have extra long heatwaves without being interrupted with days of rain.
