Wednesday, September 28, 2016 - Morning Weather Discussion

Severe flooding possible in parts of the Middle Atlantic and a hurricane to watch…

There will be severe flooding in parts of the Middle Atlantic over the next day or so as a strong upper-level low approaching from the west will cause a surface low pressure area to develop over the Middle Atlantic States. This storm will then sit nearly stationary through Sunday, before finally moving out Monday morning. This will cause very heavy rain to develop today and tonight from Central Virginia, through the Baltimore and Washington DC areas, north through Harrisburg PA, and Central NJ, and eastward through Northern Delaware and into Southwestern and West Central NJ.  Some locations in this area could receive up to or more than 7 inches of rain, and possibly even 10 inches or more of rain in the next 36 hours or so. If these higher rainfall totals do occur, severe and possibly historic flooding would occur in those areas. Right now the most likely areas to receive these extreme rainfall totals would be over Northern Virginia, extreme Eastern West Virginia, Eastern Maryland, including the Washington DC and Baltimore areas, north through about Harrisburg, PA, and east through Eastern Maryland and Northern Delaware and into Southwestern NJ.  In these areas there will be the potential for roads and bridges to wash out, so if traveling to these areas, please be careful. The heaviest of the rain will fall tonight into tomorrow morning.

In the New York and Allentown Metropolitan areas there will be some rain developing this afternoon and tonight, with some heavy rain possible in Eastern PA and West Central NJ where some flooding would be possible. Areas further to the east should just get some rain, with flooding much less likely as you head to the coast, NYC, on Long Island, and in Southeastern NY State and Fairfield County, CT. In fact, Eastern Long Island and Fairfield County, CT might just get some light rain.

The heaviest of the rain will fall tonight into tomorrow morning and then we will continue to have a chance of showers the rest of the day tomorrow through Monday morning. Highs will be in the upper 60’s to mid 70’s today, the mainly the 60’s tomorrow, the mid 50’s to the mid 60’s Friday and Saturday, the 60’s Sunday, and the mid 60’s to the mid 70’s Monday.

Tuesday through Thursday should then be nice with highs in the mid 60’s to the low 70’s.

Next Friday will be variably cloudy with a chance of a shower or thunderstorm in the morning as a cold front passes through our area.

Next Saturday through Tuesday should then be nice with highs mainly in the upper 60’s.

The other thing of interest to watch will be a hurricane approaching from the Caribbean the middle of next week. This storm will either head into the Gulf of Mexico or up the East Coast. There is the potential for this storm to become very strong. It is still uncertain where exactly this storm will go, so we will need to keep a very close eye on it.

Have a fantastic day!
