Heavy Rain Tonight
Rain will become heavy at times later tonight and this could result in some poor drainage and other localized flooding.
Low pressure will develop along the mid-Atlantic coast later today. An area of enhanced rainfall is likely to develop from the New York City area up into Connecticut and the rest of southern New England. This can be seen on the models as a moist theta-e axis.
The low becomes cut-off and only slowly drifts east from Sunday night into Monday. The result here is that periods of rain should continue at varying intensities through Sunday. Any leftover showers on Monday should be relatively light.
