6/25 – Rob’s Final Week of June Forecast

Summer has arrived, though technically has been the case for a while now. In the upper portions of the atmosphere, the Bermuda ridge extends across the western Atlantic to the central Gulf Coast with a second ridge centered near the Baja of California with a trough of low-pressure moving through the northern Plains. This puts the region on the western periphery of the Bermuda ridge, while subsidence isn’t strong enough to stop all daytime convection, temps will max out in the lower 90s with very few showers and t-storms.

The resultant heat indices should mainly be in the 100 to 105 range with isolated areas seeing up to 107. This falls below heat advisory criteria of 108+, so one will not be issued today.

The remainder of this week will basically be the same each day with highs in the lower 90s, heat indices right at to just below heat advisory criteria, with scattered afternoon t-storms elevating mid-week through the weekend.
