AN UNSETTLED WEATHER PATTERN WILL CONTINUE THROUGH THE HOLIDAY WEEKEND DUE TO A STATIONARY FRONTAL BOUNDARY

A frontal boundary that has for the most part stalled across the Mid-Atlantic States will maintain a chance of showers and thunderstorms throughout the holiday weekend. It is impossible to nail down the timing and placement of the wet weather. Weak areas of low pressure moving eastward along the front coupled with upper-level disturbances will enhance rain chances at times. Although an isolated severe thunderstorm is possible, weather forecasters are saying that the main threat is localized flooding due to heavy rain. Of course, lightning is always a threat in thunderstorms that contain cloud to ground lightning. At the time of this writing, there is no significant rain around the area. However, that is expected to change this afternoon as a disturbance is expected to bring a chance of showers/storms. Many times when we get into a pattern like this, there will be periods when the sun shines and all is well. However, don’t let your guard down as storms can fire up any time, especially when humidity levels are this high. What about the various firework displays scheduled on Saturday? It’s very hard to say whether they will be impacted at this time. If you plan to attend any outdoor event this weekend, please keep an eye to the sky and the radar. The chance of showers/storms may extend well into next week as a trough is expected to remain over the Eastern United States…. The tropical Atlantic is quiet for now. That’s it for now. Enjoy the holiday weekend and please be safe!
