8/10 – Brittany’s “Lingering Showers” Wednesday Afternoon Forecast
Convection is ongoing across the region this afternoon. Going into tonight, a few scattered showers should continue to cycle downward over the land-based zones as the diurnal cycle shifts offshore. On Thursday the flow shifts more northerly as the aforementioned weakness continues to amplify over the Carolinas and Mid-Atlantic States. As the surface, a weak frontal boundary will move southward toward the I22/I20 corridors in AL/MS before slowing down as it nears the coast. At the surface, the fire hose of low level moisture will continue from the southeast as the area remains on the western periphery of the subtropical high centered across the W Atlantic. Thursday appears to be another wet day with efficent rainfall producers once again. Hydro concerns will be possible, especially over urbanized locations and locations that recently received very heavy rainfall amounts near the AL border.
Toward the end of the period, the surface front continues to inch closer. Again, the continued return flow (although a bit weaker) will continue to allow/maintain deep tropical moisture. As the surface boundary nears the region, this will provide yet another source of low level convergence for enhanced diurnally driven convection. Temperatures over the next couple of days will likely be a bit on the lower side given the increase in rain and cloud cover.
