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.
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:
With the dry weather now affecting the Northeast, are any signs of change? These two maps show the GFS-predicted total rainfall (1) between today and the end of this weekend and (2) between today and the Saturday of next weekend (Memorial Day weekend).

A cold front crossing the Midwest will move all the way to the East Coast by the end of the day tomorrow. You can see the front on this map. Showers and thunderstorms will develop ahead of the front this afternoon, and some can become severe.
