There aren’t too many weekends where I can post the forecast on the preceding Thursday and have high confidence that the forecast won’t change appreciably.

We are locked into a dry, unseasonably warm (hot) pattern from a strong upper level ridge of high pressure.

Friday’s models show a weak upper air disturbance rotating through mid to late afternoon Saturday. Some mid level cloudiness Saturday afternoon. A slight chance of a widely scattered shower 3-5 PM ; most areas dry.

Saturday Update: Any showers on Saturday afternoon will be far northwest suburbs, Pottstown north and west.

While the new GFS model has high temperatures in the upper 80s, many models, including the NBM, have highs of 92° on Saturday and 93° on Sunday! Saving us from the summer-like heat will be dew points only in the upper 50s to around 60°.

We could use some rain (of course, never on the weekend), but none is in sight.
