Another Soaker Thursday
Since last Friday, locations up and down the Northeast Corridor have been inundated with anywhere from 3 - 6” + of rain. As a result, flood-prone areas have had problems with ponding water along with overflowing creek and river beds. Thankfully, other than showers today, drier weather is expected into Wednesday, which should bring some relief to those areas. However, this relief may only be temporary as we continue to monitor another possible rain maker for this Thursday.
A potent low-pressure system looks to develop in the Mid-West and track eastward into the Northeast on Thursday. Some good news is that the amount of tropical moisture being tapped is less than the previous couple of systems. However, strong dynamics associated with this low-pressure system may counteract this deficiency. For now, an area of 1 to 2 inches of rain (locally higher) looks likely somewhere in the Northeast. Some guidance suggests that areas already hardest hit are in line for another soaker, while others prefer a more northern track with higher rainfall totals across central New York and northern New England. A depiction of this discrepancy can be seen looking at last night’s GFS and Euro runs (showing 24-hr rainfall through early Friday morning; first purple shading is 1.5 inches of rain):
In addition, severe weather may be a problem with severe threats possibly including hail, damaging winds, and even tornadoes. People that may need to be on alert are those located south of the Mason-Dixon line and into Virginia; however, this area may shift north depending on the final track of the low-pressure system. Stay tuned for future updates on this latest storm.
