The smoky haze that has been present this week will linger through the weekend. High pressure overhead is helping to keep a lid on the smoke and it is having a tough time dissipating into the atmosphere.
The Air Quality for this afternoon in Roanoke is forecast to be “moderate” so prepare accordingly if you are prone to health issues related to pollution. This is mainly smoke particles, but still a concern.
As for the forecast, expect to see some spotty storms popping up in the heat of the day as there will be a weak wave of energy arrive late day and provide some storms. Not much in the way of widespread storms, but a few “pop and drop” thunderstorms could develop. Highs will be about normal for late July, topping our in the middle to upper 80s. The best location for the storms today will be the Piedmont.
Sunday will be a bit warmer but less of a chance exists for some storms. Monday will be our day for more of a widespread rainy day. Temperatures will be in the 90s for a while, so prepare for a mid-summer heat wave.
As for the tropics, there is a watchful eye on an area of circulation just off the east coast of Florida. There is potential for this to become a tropical depression before the end of the weekend. This could develop into our sixth named storm of the Atlantic Basin this year and Fred will be his name.
In the western Pacific, a Tropical Storm is moving toward Japan, Nepartak, and may impact the Olympic Games next week.
