PITTSBURGH (KDKA) — Western Pennsylvania has clear skies and pleasant temperatures Saturday morning.
High pressure has settled over the Great Lakes and will linger over the region for the remainder of Saturday and Sunday before slowly dissipating and moving east. This will keep a largely inactive weather pattern continuing for our region through the weekend.

Highs on Saturday are likely to reach the mid to upper 80s, especially for lower elevations. Temperatures rose further on Sunday as light southerly winds carried warm air to the area. The air will be relatively dry on Sunday, so temperatures should reach into the 90s, especially in lower elevations and urban-centered areas.

As noted in previous forecast cycles, opportunities for moisture and precipitation recovery are delayed due to the increasing likelihood of a blocking pattern in the region. A system over the East Coast will slowly move northward into New England Sunday night into Monday, blocking and supporting flows from the Great Plains states. That means western Pennsylvania will be sandwiched between these two terrains, with dry and warm weather likely to persist into Monday.

By Monday afternoon and evening, we should see increasing clouds and perhaps showers moving into eastern Ohio. These showers may struggle to move eastward initially, but as the upper air flow becomes stronger, that should help keep scattered rain and storms moving into our area on Tuesday and especially Wednesday.
The severe weather does not appear to be a concern at this time, as there will be weak winds aloft to prevent the storm from organizing, and the instability is quite weak. With increasing cloud cover and rising humidity, daytime temperatures will hover in the upper 80s to low 80s through the middle of next week, with morning lows in the upper 60s to near 70 degrees. By the end of next week, a warming trend appears reasonable.
