Hurricane Sandy continues to be the focus of attention as we head into the weekend. Consensus is building that the storm will combine with the cold front to our west to have a significant impact on our area.
*The Setup*
The high pressure to our northeast will block and even steer Sandy towards the coast early next week. Meanwhile, Sandy continues to slow and grow in size. This is important to remember when looking at the path outlined by the National Hurricane Center. Sandy will likely be a very large in size and will bring significant impacts to a very large portion of the east coast regardless of the exact path.
Sandy is currently over the northern Bahamas and moving northwestward. Maximum sustained winds are now 80mph. This general motion and strength are expected to continue today before Sandy makes a gradual turn back towards the northeast tomorrow. This is due to the front to our west that will eventually absorb the system. 
Highs today will be in the low to mid 70s.
Expect widespread showers and even thunderstorms tomorrow and tomorrow night. The showers and storms will be capable of heavy rainfall in a short period of time.
Rainfall totals will approach an inch, with higher amounts possible from thunderstorms. Highs tomorrow will be in the upper 70s.
Expect rainfall to continue to build through the morning with thunderstorms developing after noon. The best chance for severe storms will be later this afternoon and evening as the front moves closer. Damaging winds, heavy rain and isolated tornadoes are possible. Please stay alert and check for watches and warnings as we move into the afternoon.
