My video shows two different scenarios on the extent of rain from a storm now just off the North Carolina coast. Rain appears likely for the I95 corridor from Richmond through D.C. and on northeast to New York City. Places outside the storm's reach will have fine weather for the rest of the week,
This map shows the pressure pattern around the Carolina coastal storm. The strongest winds are found where the lines are closest together.
The upper-air pattern is forecast to change from one favoring warmth across the Great Lakes and most of the Northeast to one favoring the advance of chilly air from central Canada, The top map is a forecast for late this week; the bottom is for two weeks from today.
Some of the thunderstorms can become severe, with damaging wind and brief cloudbursts of rain. The greatest chance for locally severe storms should be in the "S" areas highlighted on this map (based on the NWS Storm Prediction Center's guidance).
There is a slight risk for severe thunderstorms later today from north-central Tennessee up across Indiana and Ohio to Michigan and eastern Wisconsin (shown by the "S" area on the map below. Thunderstorms are not predicted for areas near the coast from Delaware to New England.
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.
