Sometimes looking at computer models is not enough. Past experience is often a vital tool in forecasting. Two weeks ago...residents in the Northeast woke up to rain on the weekend...totally unexpected. Why ? An small offshore low. Same situation haunts the East Coast this weekend. Hard to say how far north the rain will go...but The Southeast thru DelMarva Area will get soaked. As to NJ on north....debatable. New England could stay dry. Here is a satellite pix from this a.m. showing the problem area along the coast.
Now you can look at the map that tells us how much rain can fall ...valid for this Saturday......followed by a map that predicts accumulated precip....again for this weekend. It's a close call from beaches from NJ to Cape Cod.
We now have a tropical depression off Africa....and another one about to form and move thru Yuchatan and into Gulf of Mexico.
If you thought it was cool in The East.....this map shows lows that have either tied the record or broke the record for this time of year. You gotta love it.
