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.

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:
