Organized severe thunderstorms are currently not expected on Thursday. ... Synopsis ... The closed mid-level low off the coast of the Pacific Northwest will begin to lift north/northeast on Thursday. As it does, strong southerly mid-level flow will force height rises across the northern US Rockies and southwest Canada. These rising heights will allow the mid-level ridge across much of the US to redevelop northwestward --from the Midwest toward the northern US Rockies. At the same time, the second strong mid-level trough this week will move across New England, bringing with it a reinforcing shot of seasonably cool and dry air. A surface cold front will push southward through New England, ending up in the vicinity of the Mid-Atlantic by Friday morning. The airmass across much of the US, especially areas east of the Rockies, will be very warm and moist with afternoon temperatures generally 5-15 degrees above normal outside of areas with widespread cloud cover and precipitation. Mid-level flow will be generally weak across areas of the US with adequate buoyancy for thunderstorm development. Thus, the severe weather potential on Thursday remains too low to warrant unconditional severe weather probabilities. ..Marsh.. 07/14/2026 $$
