The computer models all show a precipitation-producing feature affecting areas over or near the Middle Atlantic coast late tonight (1 a.m. to 7 a.m. period), but they differ from each other in important ways. This is really a time when you should plan to check back on accuweather.com a number of times as you go through the weekend. Here is the European model's take on this.
The GFS has the same features but is farther along than the Euro. The Euro showed some enhanced precipitation in New Jersey and New York City during this period, while the GFS has the same thing in southern New England.
The NAM seems to have the same timing as the European model but is lighter and less extensive with the precipitation:
The current maps with precipitation areas give few clues about which model will be best.
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:
