Pinpoint Weather: Showers along the coast, over the mountains and cooler than normal conditions

Weather Blog

Not a very difficult forecast if you are looking at the general and overall pattern. A stationary front along the coast with an area of low pressure riding along the coastal plain this week will give rain mainly to the areas east of our viewing audience.  The low will push air in from the coast toward the Appalachians and the mountains will squeeze out a few showers most of the week. 

Locations in between those features will see clouds and a bit cooler than normal air.  In a more specific forecast, that presents a bit of a problem as spotty showers and a few isolated storms may arrive from time to time.   The high in New England is also going to provide us with a cool wedge of air over the Piedmont and along the Foothills so there may be some pockets of fog early in the morning and a low cloud deck if the cool air mixed with the warmer air from the east.

As for the temperatures, expect to see below-normal air temps as the mercury will be in the upper 70s west and low to mid-80s east.  The clouds will determine the need for adjustment in the daily prognostication of the temps as more sun gives us more warmth.  Again, fairly simple right?  Except the amount of sun is going to be hard to nail down, the extent of the cooler air is always a challenge to anticipate, and the rain apart from the coast will be fairly spotty. 

The pattern maintains until the end of the workweek and the highs will be gradually increasing as the week moves along. The return to the 90-degree heat arrives over the weekend along with the chance for some pop-up storms.  The heat will be back until at least the middle of next week.

Air quality today and Wednesday will be in the Moderate Range in Roanoke. Not much of an issue for most but some may need to take precautions if they are unusually sensitive to air pollution. Smoke is the main particulate matter.
