A Slow Decline in Shower Coverage

Good afternoon folks! The main event is underway as Tropical Storm Isaias continues to move toward the SC/NC line border along the coast, aiming for a late evening landfall, possibly as a category 1 hurricane. Our neck of the woods is dealing with strong, scattered thunderstorms and showers as the overall flow from Isaias interacts with an upper level trough and stalled front; plus terrain influence along the escarpment. We'll continue to experience showers through Monday night, winding down early Tuesday morning, with another round of scattered showers Tuesday afternoon under passing clouds. By Wednesday the upper level trough will be swinging a few disturbances our way, prompting scattered showers after midday, but we should be able to squeeze out an hour or two of more sunshine compared to Tuesday. We'll slowly transition to a normal summer time setup by the end of the week, with more sunshine overhead than clouds, temps back in the mid - upper 80's and isolated pop up storms each afternoon.

Tuesday and Wednesday will be similar in that shower coverage will be the same, roughly a 40 - 50% area coverage, favoring the TN line and nearby ridgelines both afternoon. Some clouds start out the day on Tuesday but sunshine will take over as we near the noon hour, with showers firing off during the mid - late afternoon hours. Wednesday will play out much the same, however there is likely to be more sunshine overhead before noon compared to Tuesday. Either way you slice it, temps will remain the same with temps in the upper 60's - low 80's depending upon elevation for both Tuesday and Wednesday. Overnight lows settle into the mid 50's above 4500', while the valleys settle into the low 60's.

Thursday and Friday look pleasant for early August with another round of scattered showers Thursday afternoon, scaling back to isolated coverage Friday (and possibly the weekend). Temps warm to the low - mid 80's Thursday and climb a few degrees on Friday to the mid - upper 80's. We'll stop here and circle back on Wednesday.
