A stalled front will hang out to the south & west of the area through the start of the holiday weekend & act as the focal point for occasional shower/storm activity along it & will be the divider between the searing heat & humidity to the west of it compared to the tolerable warmth & humidity here.
The warmth will probably intensify somewhat over the weekend before it gets snuffed out big time possibly later Labor Day into Tuesday. Temperatures will likely top out in the mid 80s Saturday & possibly upper 80s to possibly 90 Sunday & not too far from that Labor Day. 60s may follow by next Tuesday! The chances of rain will be slight at best through Saturday, but a little higher probability later Sunday & especially Labor Day as a cold front bears down on us. Stay tuned.
Have a great day & week WNY!
