Wednesday 8 a.m.
A cold front moving off the East coast is ushering in drier air, and places west of the I95 corridor should have fine weather through Friday. However, closer to the coast, it could be cloudy and wet because the front will stall offshore and a low pressure area may form along it.
Just looking at the morning pressure pattern (see map below the video) and the satellite pictures, it seems the dry air should spread all the way to the coast and the wet weather will all be offshore. However, most computer models show the upper-air winds shifting from westerly to southwesterly along the coast, and they show a band of clouds and rain forming from coastal Virginia to New Jersey and on northeastward through eastern New England.
If that happens, the moisture could easily stay in place on Friday. During the weekend, the next front from the west is likely to cause showers and thunderstorms on Saturday over the Great Lakes and Ohio Valley, with the showery weather heading toward the Middle Atlantic states and New England for Sunday.
(Note, when I just mention "the Northeast," I am referring to the area from Maryland to Maine and out through the eastern Great Lakes. If I think there will be noticeably different weather regimes within that large area, I may use Middle Atlantic states, eastern Great Lakes and/or New York and New England. Admittedly, I can be inconsistent with those descriptions. When you see the video and other pictures, the specific areas I am talking about may be clearer than what you get just from the text.)
Here is today's video:
For now, a northerly flow of drier and cooler air is coming into the the Northeast. However, if the front stalls and a low pressure area forms along it, moisture would return to the area over or east of I95 as early as tomorrow.
It is not going to snow any time soon, but in any type of weather the flag is a symbol of freedom. This holiday weekend we celebrate the contributions of those who were there to defend the freedoms we enjoy in these times.
Once again, the rain will miss much of central and northern New England. The region has been in a dry spell, as evidenced by its appearance on this U.S Drought Monitor map.
A cold front crossed the Northeast yesterday. Looking at these maps, which show morning temperatures yesterday versus readings around the same time today, we can see that the biggest drop in temperatures occurred around the lower Great Lakes.
Much of eastern New England has been in a dry spell ever since the last snow melted. More dry weather is on the way from tomorrow through the end of the week. This radar image taken at mid-morning Tuesday is peppered with showers.
Cooling will also occur from Wisconsin into western Michigan as a cold front moves eastward. This map shows the arrangement of fronts and the area of relatively warm air between the two cool air masses:
The worst storms later in the weekend will precede the cold front that brings cooler air back into the Northeast next week. This map shows the threat as outlined by the NWS Storm Prediction Center:
