Returning Humidity & PM Storms

After an interlude of somewhat drier air this past weekend, humidity levels will start to creep back up from here. With the increase in humidity, comes an increase in instability that will once again result in an uptick of PM showers and thunderstorms as we move through the week. Temperatures will remain a little bit warmer than normal through the period.

Western NC felt a M5.1 earthquake Sunday at 8:07 AM. The center of the event was almost 2 miles SE of Sparta NC. Here's the USGS live report about the event. This earthquake was preceded by eight smaller quakes beginning Saturday morning near the same location. It was the second strongest earthquake ever recorded in NC; only a 1916 event in Buncombe County was stronger (M5.2). Many buildings and a few roads in Alleghany County were damaged and minor damage has been reported in the 50 mile radius of the quake. The quake was felt from New England to Mississippi.

Forecast Discussion

Moisture builds through the region this week with increasing humidity. Initially, we think shower and thunderstorm activity will be few-and-far between through Tuesday before ramping-up quite a bit for the remainder of the workweek.

There will be two weather map features to watch this week: One will be the Bermuda High as it becomes better established, serving to transport Gulf and Atlantic moisture into the Southeast States. Second will be a frontal zone that will become draped from the Ohio Valley eastward to the Mid-Atlantic coast.

The front will not come through here this week. However, moisture pooling along and south of the boundary will serve as a focus for scattered to numerous showers and thunderstorms around western North Carolina. Rainfall coverage will concentrated on the afternoon and evening hours, but not necessarily limited to them.
