Pinpoint Weather: Scattered storms into the night to end July, pockets of fog and some rain start August
Ending the month of July on a warm note, which is not surprise since we have been in the 90s every day except one.
The string of 90s is over but the overall temperature average for the month will go down in the books as the “Warmest July ever” and the second warmest month of all time. This was a warm month to say the least. Now we are putting July 2020 behind us as well as in the record books and now we turn our attention to August.
Saturday will be a day that will feature some foggy conditions to start, then scattered storms are more than likely expected to develop in the afternoon. Highs will be in the upper 80s to low 90s east of the Foothills, and in the middle 80s in the mountains. A stationary front will continue to serpentine across the Commonwealth into Saturday night before shifting north as a warm front. This movement or lack of movement will allow storms to ignite along the front and give us more showers and storms. More than likely the storms will be in the late day time frame. The Storm Prediction Center has a portion of the region in the Marginal Risk Category for severe storms, but locations north of 64 in the Slight Risk Category. The main threat is going to be gusty wind and possibly some large hail, but there is the potential for some rotating storms to develop so ther is a very small risk of a tornado, again, mainly north of the region but close enough for concern.
Sunday will be the warmer day, but not by much, as the stationary front migrates toward the north as a warm front. As the name suggests the warmer pattern will be present, but the impact will be the same. I still expect to see the storms pop up in the heat of the day so we still need to be mindful of the skies as some of the storms may generate some gusty winds, heavy rain that could lead to flooding and dangerous lightning.
As for the elephant in the room…Isaias is expected to travel up the eastern seaboard and provide many problems for the folks along the coast. The NHC has him as a Cat one all the way from Miami to Moorhead City but may be a bit stronger if he drifts a bit more into the Gulf Stream waters in the Western Atlantic. The impact for us will be rainy and windy conditions. The overall focus of the rain will be over the Coastal Plain but the winds and rain will kick west into the Piedmont and there may be some flooding from the Blue Ridge escarpment to the sea. A cold front is expected to push over the mountains Monday and help to lift out some rain as well, so there may even be some impressive rainfall totals along the spine of the Appalachians on Tuesday as well. Timing is always an issue with these big lumbering cyclones, but Tuesday looks to be the day Isaias will push north to the Delmarva Peninsula. Monday night into Tuesday afternoon may be the best time to get the greatest impact from the ninth named storm of the Atlantic Hurricane season.
