Flooding concerns continue to be high across the region today with steady, and at times heavy, rainfall expected to continue through at least the morning hours. The rain will taper to showers this afternoon, but not before significant rainfall will have provided a much needed soaking for the previously parched ground across the Capital Region. The greatest flood threat appears to be localized flooding of urban and poor drainage areas, as well as small streams, especially through the morning hours today.
A slow moving cold front will trudge through the area by afternoon, slowing to a crawl to our south before stalling along the New England and Mid Atlantic coasts tonight. Brisk and raw northerly winds will filter a cooler airmass into the region behind the front for the later portion of the work week with additional showers possible straight through the start of the weekend as an unsettled pattern evolves over the region.
There continues to be significant uncertainty with regard to how the stalled frontal boundary interacts with Tropical Storm Joaquin late in the work week and through at least the start of the coming weekend. The ultimate track of the tropical entity will influence the chances for precipitation across the region, particularly on Friday and Saturday. Stay tuned for further updates and forecasts.
