12:10pm an unusual weather pattern has set up over the eastern United States. A High Pressure system over the Atlantic Ocean commonly referred to as the Bermuda High is acting as a blocking mechanism not allowing the Jet Stream to oscillate. This has produced a frontal boundary that is acting like a conduit for tropical disturbances; these tropical entities develop in the western Caribbean Sea then race northward up the eastern sea board. Currently Tropical Storm Nicole is one of those tropical entities that has developed and is expected to produce the next round of heavy rain. This feed of tropical moisture will likely produce flooding up and down the eastern United States; the significant threat for flooding has prompted flash flood watches and warnings from the Carolinas north to New York State and New England. The rain will overtake the region by Thursday and continue through Friday evening. Expect excessive amounts of precipitation and flooding. Also, due to the dynamics of the atmosphere producing strong gusty winds near 40 miles per hour combined with soaking rain some trees will easily topple over. In addition, the wind shear in the atmosphere could even produce an isolated Tornado or two. High temperatures will remain in the 60s and 70s in the Northeast but will take a tumble by Saturday. As the frontal boundary finally moves away from the coast on Saturday it will usher in a cool air mass that should drop temperatures by 10°F to 20°F.
