AN UNSETTLED WEATHER PATTERN WILL MAINTAIN A CHANCE OF SHOWERS AND THUNDERSTORMS FOR SEVERAL DAYS

The combination of a stalled frontal boundary to our west, a trough of low pressure, and a moist flow around a high pressure ridge in the Western Atlantic will keep our weather quite unsettled for several days to come. You may have noticed that the chances of rain keep changing each day. This is due to the uncertainty that exists as to where and when the showers/storms will develop. For example, yesterday (Friday), there was a line of storms approaching Hampton Roads. The line north of the VA/NC border weakened while the line south of the border stayed intact for the most part. My Virginia Beach neighborhood only saw a period of light rain. Another area of light rain moved through during the night. This morning, a heavy thunderstorm moved just south of my area missing us again. There will be plenty more opportunities for rainfall but it is nearly impossible for forecasters to predict who will get the rain and when they will get it. The pattern is stagnant and the front may even retrograde to the west at some point. So, expect warm and very humid conditions to continue for several days with a continued chance of showers/storms. During rain-free and sunny periods, it will feel quite oppressive due to the relatively high dew points. Some localized flooding is possible so be alert and monitor the local media and NWS forecasts… Note that while there is a trough in the eastern part of the nation, there is an extensive ridge in the western states which is causing the intense heat out there.
