Pinpoint Weather: Flood threat continues overnight and Thursday

Weather Blog

The low-pressure system that has kept the region in a persistent pattern of rain is finally starting to move. The bad news is that we are still in line to get more rain and the threat for flooding is once again expected Thursday.

Rainfall amounts over the past few days have been impressive and the ground has been getting saturated with each shower that passes overhead.  Today the rain was much more robust and also, we had a few thunderstorms.  Flood Advisories, Flood Warnings, Flash Flood Warnings and River Flood Warnings were all issued at some point during the day Wednesday.  The estimated as well as measured rainfall amounts are staggering.  In South Boston over the past 24 hours, 7.86” of rain was measured in the gauge.  In Roanoke at the WFXR Studio we measured 2.36” today.  There are still a good deal of raindrops still to fall before this upper level low exits the Mid Atlantic region.

The low is expected to move to the north over the next 12 – 24 hours but still be in position to provide us with more rain. The change will be it should start to warm up. The origin of the rain will be from the south and west which will bring in some milder air. Temperatures will still be below normal, but creeping closer to the 80s than dropping toward the 50s.  Still, the rain tomorrow may be a bit robust again as the heating may allow for a bit more energy to be generated. Although not expected to get much in the way of severe storms Thursday, we may still hear the rumble of thunder and get some brief heavy downpours. 

Stay alert Tomorrow as we can’t let our guard down just yet.  Spotty showers are also expected Friday and Saturday.  The saturated soils will not be able to hold much more rain so flooding again may be fairly widespread.
