The impacts of Tropical Storm Isaias will enter our region Monday afternoon and continue throughout the day on Tuesday. Showers and storms are likely, but the most significant impact will be the massive amounts of rain it drops.
A Flash Flood Watch is in effect for late Monday afternoon throughout most of the day Tuesday. 3-6 inches of rain plus heavier amounts locally may cause creek and stream flooding. Floodwaters are again possible in urban areas that are poor to drain off excessive amounts of water.
Winds associated with isolated thunderstorms may also add to the threats. Most of the severe weather on Monday will be along the Carolina Coastline. While still under a marginal risk here in our area, the likelihood of increased storm development will mainly be east of the Blue Ridge Mountains.
Tuesday’s severe weather looks to be along the DelMarVa Coastline, while most of the stronger storms will be to the east, heavy rainfall brings the risk of scattered to widespread area flooding. Flash flooding will also remain a threat mainly along creeks and streams and other areas poor to drain. If you come across floodwaters, turn around and find another route.
Things start to exit out of the region on Wednesday. We see a bit of sunshine that carries on throughout the end of the week. While things will be less humid Wednesday and Thursday, the heat will increase as we head over the weekend.
The temperature trend for the week will be below average. Still, as we head into next weekend, temperatures will begin to trend closer to the average before going once again above the usual temperature Sunday.
Here is a look at your 7-day forecast:
Sunday night: Increasing clouds with a chance of showers and storms, mainly before midnight. Lows will be in the upper 60’s and low to mid 70’s. Winds will be out of the southwest at five mph.
