Key Messages
- One more day of below normal temperatures today
The coastal low that plagued parts of the area over the past couple of days is now located over the Virginia Tidewater region this morning. The low is expected to meander around the NC/VA border today while weakening. A moist, cyclonic flow around the southern periphery of the low is expected to keep low clouds socked in across much of ENC today. The one exception is across areas south of HWY 70 where a drying westerly flow may allow clouds to scour out quicker. Where clouds clear, low-level thicknesses support highs quickly warming into the low 80s. This is expected to setup a tighter temperature gradient across the area, with areas north of HWY 70 struggling to get out of the 60s, especially where cloudcover is the most persistent. Additionally, areas north of HWY 70 have the best chance of seeing a few showers as an area of low-level convergence pivots east through the area to the south of the low.

The weakening coastal low will finally move more decidedly east away from the area tonight. In the wake of the low, weakening winds and clearing skies may support a fog risk across parts of the area, especially inland where low clouds are expected to clear the quickest. The latest probabilistic guidance suggests the risk of dense fog is LOW (
