The remnants of Florence are centered over the Ohio Valley at mid-day and showers and thunderstorms are wrapping around the system and now impacting much of the Mid-Atlantic region. The threat for occasional rain and thunderstorms will continue in the I-95 corridor into the early part of tomorrow night when a frontal system will finally clear things out. Some of the rain will be heavy at times and some of the storms can be on the strong side. In fact, accelerating tropical systems of this nature sometimes generate tornadic-producing thunderstorms on its east side so that may also become a threat over the next 24-36 hours.
Rain has arrived in the DC metro region and should push into Philly later this afternoon and then into New York during the early evening hours. Radar echoes are quite impressive across southern Virginia and this is a warning that some heavy rainfall can push into the I-95 corridor later today and tonight. Embedded thunderstorms are also likely to become quite strong in areas west of the I-95 corridor (e.g., western Virginia) and the threat for isolated tornadoes is on the table.
On Tuesday, the remains of Florence will merge with a frontal system and there are likely to be more showers and storms in the I-95 corridor – some of the rain can be heavy and some of the storms can be strong. Once the front clears the region early tomorrow night, skies will tend to clear and this will pave the way for much nicer weather during the second half of the week.
High pressure will build in for the Wednesday-to-Friday time period and we’ll experience generally dry, sunny and comfortable conditions around here although the humidity will build on Friday. At the end of the week, a frontal system will approach from the northwest and it may stall out somewhere in the Mid-Atlantic region during the weekend which could result in somewhat unsettled weather conditions.
The tropics have become generally quiet in the Atlantic Basin and should stay so for the next several days. In fact, currently, there are no tropical storms/hurricanes/cyclones anywhere around the world which is quite unusual for the middle of September and it hasn’t been this quiet since the end of July. There are signs, however, for a resumption of tropical activity in the Atlantic Basin later this month and/or during the month of October.
