A cluster of thunderstorms is moving through Louisiana and Mississippi this evening providing heavy rain and plenty of cooling air for the sultry Gulf coast.

A heat dome or ridge of high pressure in the middle-atmosphere is building over the West Coast with height anomalies centered on northern California. The result is extreme heat into the 100s in the Central Valley and 110s into Phoenix. Death Valley should see 125\u00b0F.

Pop-up summer-time thunderstorms dot the landscape east of the Mississippi in high-dewpoint air. However, as June continues, organized low pressure systems are rare and instead we see convective blobs or lines of storms rounding the ridge. Later this evening, a cluster of thunderstorms should fire in OK and sag southward into Texas including Dallas-Fort Worth.

\"\"

Severe storms are possible later tonight into the overnight hours along a frontal boundary that outlines a trough.

\"\"

The ridge of high pressure is centered over the Western U.S. with dips or a series of troughs extending from Alaska into the Midwest.

No heat dome development east of the Rockies in the next 2-weeks? Looks like that\u2019s the case going forward through mid-June.

HRRR shows a cluster of storms developing in the Plains and blasting southward through Texas perhaps just east of DFW. The outflow boundaries could see gusty and damaging winds. These convective systems are very beneficial for rainfall although no shortage of precipitation:
