Backdoor cold front brings some temporary relief first part of the holiday weekend… temps increase 2nd half…

Some relief arrives Friday with a weak backdoor cold front nudging in from the east as high pressure pushes SW from New England. Still expecting very little in the way of storm activity on Friday. Have split temperatures in the graphic above, as areas closer to the Lehigh Valley will remain closer to the 84°F mark, whereas the Lower Susquehanna Valley will reach the upper 80s until that front moves through.

After a “cool” Saturday only reaching the lower 80s with the backdoor front influence and an east wind, the winds turn southeasterly on Sunday with temperatures headed back north again. Labor Day Monday looks dry with temperatures headed to the upper 80s once again, and winds turning southwesterly. That same theme continues for Tuesday, and then a cold front approaching from the west will introduce an isolated thunderstorm threat later Wednesday along a pre-frontal trough. It will be this front that will move through on Thursday and knock back temperatures significantly beyond Thursday.
