Flash Flood WatchJune 30th, 2013 at 10:38 pm by Tiffany Savona WAVY under Weather
A Flash Flood Watch was issued for the entire viewing area starting tonight and lasting through early Tuesday morning.
Heavy rain will be the main concern with any shower or thunderstorm that develops tomorrow. Any additional rain that falls on saturated ground can lead to flash flooding. Flash flooding could also arise if showers and storms continue to develop over the same areas for several hours.
We did see a batch of showers move across Hampton Roads early this morning, but then we got a break during the afternoon. Most of the rain developed along and west of I-95 this afternoon, along the stationary front. This front barely moved, hence the name, causing several rounds of heavy rain to move over the same areas.
Showers and storms will be possible tonight, but the best chances for rain will be during the day tomorrow. Rain should become widespread tomorrow due to several waves of energy rounding the base of the large upper-level trough. Jeremy wrote an interesting blog on Friday explaining why this current weather pattern is very unusual during the summer months.
There is a very large dip in the jet stream over the eastern half of the U.S. All areas underneath this upper level trough are experiencing unsettled weather (showers, storms). On the flip-side, an upper level ridge has become stationed over the western half of the U.S. Many of these places are seeing record breaking heat. Check out the high temperatures across the nation today…lots of triple digit readings in Utah, Nevada, California, Arizona and Idaho. These locations are seeing temperatures about 10°-20° above average for this time of year!
It finally looks like we will see this weather pattern break down by the end of the week. So rain chances will be highest tomorrow with a decreasing trend for the rest of the week.
Right now we have a slight chance for an afternoon shower/storm on the Fourth of July, but it looks like most will stay dry. Stay tuned for the latest updates.
