21:30 UTC Billings MT mid-afternoon MD

[21:30 UTC] Storm initiation is well underway across central portions of the Billings CWA and enhancement of multiple updrafts/storm cores has been noted over the past hour as increasing low level destabilization combines with relatively modest deep layer shear to support increasing storm development and potential organization. Still expect most of the widespread coverage this evening to work into our area from the south, but ongoing storms will still need to be watched, especially as they near the frontal boundary draped across our north. Do think that these storms will gradually transition from mainly a hail threat now to more of a damaging wind threat later. Additionally, cannot completely rule out an isolated funnel or tornado given low level turning.
