Mid Atlantic & Northeast Rainfall March 20-23rd




Low pressure is currently developing over the south central United states and will continue to push off to the east south east and form a surface low over Arkansas. This will be a slow moving system with a cold front extending south and another cold front extending northeast to a low pressure in southeast Canada. This frontal boundary looks to settle and become stationary northeast to Southwest thru PA.

This area of low pressure should be across eastern Kentucky by monday morning. From there this low pressure will generally move east north east and off the SNJ Coast before moving ENE along the Northeast coast.

This low pressure and its associated frontal system will bring rainfall once again across the region. There is some concern at Real Wx Services with the movement of the system and the heaviest rains falling over regions that are still not recovered from the last system that brought flooding to the region. Real Wx Services feels that there is still enough time to monitor the situation before feeling the need to issue any level alerts for flooding. So stay tuned for further updates if they become necessary.

Severe weather parameters at this point are not all that impressive with poor lapse rates and Cape levels. And with the rain will create a stable atmosphere as far as severe weather.



Real Wx Services is monitoring the possibility of precipitation changing to snow across locations like Maine. Any snowfall potential would be across the higher elevations as this will be a primarily rain system. However..there is a possibility that as colder air comes in behind the front that there could be some snow in the highest elevations . So stay tuned for more on this potential.
