Forecast Update: Flooding a concern through Tuesday...
A frontal boundary in combination with tropical moisture from Isaias will make for a very wet period lasting from now through at least midday Tuesday. The rain Monday was due to this front draped overhead. Some of the rain was heavy, some of the storms were on the strong-to-severe side. While the severe threat is there for us through Tuesday morning, the bigger concern is with the flood threat. Areas west of the Parkway could see up to 2” of rain, while areas east of the Parkway could see up to 3-4” of rain. It would not at all surprise me if there were isolated higher amounts. The heaviest rain will fall between Monday afternoon and Tuesday morning, with some breaks possible every now and again. We’ll also need to keep an eye on the river levels too, as they will probably rise too because of all the rain headed our way. Isaias is expected to make a landfall this evening somewhere along the Carolina coastline (best bet right now: somewhere between Myrtle Beach and Wilmington). While the highest threat for a tornado will be closer to the coast, a stray one here cannot be ruled out. Please stay tuned to Your Local Weather Authority for all the details.
Tuesday will be wetter in the morning than it will be in the afternoon, and will be wetter east than it will be west all day long. Temperatures on Tuesday will reach the middle 80s. Wednesday will not be as wet. Spotty t-showers will still be around for us, especially after lunch-time, but the coverage does not look to be too large. Otherwise we will see a mix of sun and clouds with highs in the mid-to-upper 80s. Thursday will again see a better chance for more scattered showers and storms. The best chance appears to be in the afternoon/evening as skies will turn mostly cloudy. Temperatures will reach the middle 80s on both Thursday and Friday. We will close out the work week with a little more sunshine and hit-or-miss, mainly PM t-showers. Right now, it looks like Thursday will be a bit wetter than Friday.
The weekend looks to warm up again. Temperatures will top out in the upper 80s to near 90 both days under partly sunny skies (more sun in the morning, more clouds later in the day). Both days will still have the chance for pop-up PM t-showers, but it looks more like a typical summer-time pattern for us on Saturday and Sunday.
