(WFXR) — As we move forward through the week there will be a noticeable scenario that will dominate the forecast, heat and humidity with isolated pop-up storms. The storms will be difficult to pinpoint but I do expect to see them each day. This is quite normal for our region in the summer, it just seems to be a little early this season. Bottom line, temps will be in the middle to upper 80s each day and pockets of fog are likely each night along with scattered storms in the heat of the afternoon.
This heat and humidity are the result of an area of high pressure off the coast of the Carolinas and an area of low pressure off to the west. The flow of air around the high is clockwise and is tapping into moisture from the Atlantic and to some degree the Gulf of Mexico, and funneling it into Virginia. The low is helping to grab on to some moisture from the Gulf as well, and since the flow around the low is counterclockwise, they are working in concert to bring in the muggy air. Since it is hot, the heat of the sun helps to percolate the atmosphere and allow the warm and moist air to rise, then condense in the cool air high in the sky, and rain. Thunderstorms are also possible with the rain as friction between the molecules in the towering cumulus clouds is also present.
So, this pattern will be likely each day over the next several so we need to be diligent to keep an eye on the sky if we are out and about. Hiking, biking, walking, kayaking and all outdoor activities may be interrupted by an isolated of pop up storm. The storm will be slow movers so if and when they pop and drop, the drop will be fairly intense and may cause some localized flooding.
Not expecting anything to challenge this forecast for a few days, but Friday may see a cold front push through and that should scour out this pattern. Until then, stay hydrated and safe.
