Tuesday seeing lingering rain.

Surface chart and Radar

 

We have semi-stationary boundary that is drifting east, as high pressure approaches from the west. This boundary is the one that brought all the rain that was heavy at times, along with storms that brought gusty winds and hail to parts of the region. Much needed rain fell across parts of southern New England into the Middle Atlantic where widespread 1-3 inches of rain with some areas seeing even more that that fell.  The rain is lingering today over New England back into the Northern Middle Atlantic as that area of low pressure continues to slowly side south and east.  The rain will taper off from west to east later this afternoon into the evening. There is a slight risk a couple of storms over southern Maryland and Delaware could be on the strong side.

Temperatures are a bit warmer than yesterday, but they are still slightly below average for this time of year. But the front has taken the humidity out of here.

Satellite shows the location of the frontal boundary with dry air coming in from the west.

 

High pressure is going to build in and bring us a couple of seasonal days with dry conditions.  Wednesday most of the region will stay dry, but an upper-level disturbance to our north could bring a few scattered showers and thunderstorms across northern parts of the region, this will be especially true for northern Maine. The best time for this will be during the morning into the afternoon.

Thursday starts off fairly nice, but we’re going to have a warm front approaching and lifting into the region. With the front warmer temperatures will push into the region, but humidity should stay basically in check. We could have a few scattered showers and maybe some storms with the frontal passage. The cold front will come through later Thursday into Friday. The cold front will bring more in the way of widespread rain and storms.  

Friday night into Saturday will see the cold front basically stall out. This will keep the threat for rain showers and thunderstorms around, this will be especially true for Southern Pennsylvania, Maryland, Delaware into New England, where rain could be more widespread, closer to the frontal boundary. All of this will linger into Saturday. Friday looks to be the wetter of the three days.

The weather turns warmer next week,

Sunday will see high pressure completely set up overhead.   The high pressure sticks around for Monday. This will allow warmer air into the region. Then on Tuesday low pressure will be dropping out of the Great Lakes bringing rain showers and thunderstorms.

 What about July?

July is looking to be a bit warmer and humid overall than we’ve seen. But we look to have a big ridge setup over the Plains and Midwest. This heat dome will have systems rotating around it. This could mean the Northeast would become quite active as we would be on the edge of the dome, As disturbances rotate down into the region. This could mean our region sees quite a bit of storminess during that time.
