Flooding potential for The Delaware Valley Region.
I sure hope that everyone enjoyed the nice stretch of dry and spring like weather over the past 5 days. Now we pay for it, as a prolonged rain event and possible heavy rainfall could bring flooding problems, especially from Friday night into Saturday night.
A slow moving storm system, loaded with moisture will approach the region from the Ohio Valley later this week, and then move eastward to the Northern M/A coast during the weekend. Periods of Light rain will develop during the day on Thursday and continue into Friday. This rain will not be significant, but a steadier and heavier rain will develop during Friday night and continue into Saturday night. This is where the flooding problems will likely occur. At this time it appears a general 3.00" to 4.00" of rain will fall, but some isolated spots could see near 5.00" of rainfall.
With a saturated ground from recent snow melt, this heavy rain could cause flash flooding near some streams/creeks, and flooding in basements and poor drainage areas. Temperatures will continue on the mild side with Highs in the mid to upper 50's Thursday through Sunday, and lows in the 40's. Winds will also increase Friday night into Saturday out of the East at 15-30 MPH and higher gusts to near 45 or 50 MPH. So look for stormy conditions and some flooding possible especially during Saturday.
