Hit-miss showers and downpours in thunderstorms will remain possible through Sunday before a refreshing air mass change arrives to kick off the first full week of June.

This will also mark the beginning of a new pattern that may continue well into the summer season.

A heat dome will remain anchored over the western USA, with a surface center developing near the Red River Valley along the Texas-Oklahoma border.

The Mountain Empire will initially cool down into next week as much drier, low dewpoint air surges into the area around the eastern periphery of the blazing heat.

This sets up a nice stretch of weather, with chilly nights in mountain valleys, until later in the 6-10 day forecast period when the heat dome begins to expand. Due to wet ground and it’s position a ring of fire convective pattern may arise.

While the core of the heat will remain locked in place well to the west, enough heat and instability will surge eastward to support clusters of showers and thunderstorms.
A pattern like this can become locked into place for an extended period of time, with periodic expansions of the heat dome triggering clusters of thunderstorms which hold true heat at bay and occasionally allow drier, less humid air to return during a heat dome contraction phase prior to the next expansion.
The above being the idealized scenario based upon current soil moisture variations across the nation, plus past climatology of similar settings.
