 The region has been dealing with seemingly endless rain for the last several weeks. When will this end?

Here is the current surface chart and satellite image.

The surface chart shows the complex pattern across the United States.We have the upper level low with the attached cold front starting to push east and away from the region. We also have an area of low pressure and trough up over Canada with an attached cold front, that is going to be dropping south and east into the region. On top of all this we still have the upper level low that is currently over the southern Plains working its way east. Ahead of this we have rain and thunderstorms working through the Tennessee and Ohio Valleys.

The visible satellite image shows the majority of the region is still dealing with clouds. But Maryland Delaware and New Jersey currently aren't seeing  much in the way of clouds. The infrared satellite shows we still have moisture rotating around the upper level low but that a majority of the forcing that's leading to the heavier rain is off the Coast.

Image from the Storm Prediction Center (SPC) shows yesterday's damage reports.

Yesterday saw some severe thunderstorms that created damage mainly in the northern middle region There was even an isolated tornado that touched down in Northampton County Pennsylvania. Today we will see scattered showers and isolated thunderstorms over New England. But the majority of the region should stay relatively dry with drizzle and  some isolated showers; I completely can't rule out a very isolated thunderstorm.  The severe risk today is pretty much zero. So it will be a much better day then yesterday.

For tomorrow the upper level low currently in the southern plains is going to be approaching our region. As this is occurring, it is going to interact with that trough up in Canada, due to this we're going to see another upper level low develop near the Ohio Valley by tomorrow evening. Tomorrow and tomorrow night we are going to see a cold front associated with that upper level low feature approaching our region. With the cold front We can expect increasing clouds along with scattered showers and some thunderstorms, that will move north and east across the region, I can't rule out a few of these thunderstorms being on the strong side. This will especially be true for southern Maryland into Delaware.  So for most of us tomorrow should be dry until we get into the later part of the afternoon, when rain starts breaking out in western Pennsylvania then as we move through the rest of Thursday night and into Friday as that upper level low heads towards New England we are going to see increasing steadier and widespread coverage of rain and isolated thunderstorms. Friday will not be the greatest day if you plan on being outside. Rain will be moderate to heavy at times. Friday night Into Saturday we will see clearing develop southwest to northeast across the region. Saturday morning could see lingering showers up over parts of New York State and northern into parts of central New England.

Saturday afternoon into Sunday We will see high pressure approaching the region This will completely set up shop on Sunday leading to plenty of sun and dry conditions. Monday we'll see this area of high pressure start to push east. But Monday still should be dry or at least mostly dry. Tuesday the region will start out dry. Then as the day goes on we will see low pressure approach out of the Tennessee Valley. Showers associated with this should reach southwest Pennsylvania late in the day or evening. These showers will continue to push north and east across the region for Tuesday night and on Wednesday. Again rain could be heavy at times.
