Guidance depicts the blocking pattern breaking down towards the end of the week, with surface high pressure developing in the western Atlantic for a time. With a disturbance tracking to our NW and a southerly flow we should have a warmer, more humid airmass in place as a cold front approaches later Saturday. Other than getting in on some moisture on the northern edge of the southern closed low, our next best shot at significant rain looks to be associated with the energy lifting north as the pattern breaks down and the low opens.
