Shower and storm chances return... TD 4 has formed....

A cold front is dropping into the region today, and that front will kick off scattered showers and storms later today and into tonight. Then, an area of low pressure will form along the front and keep the chance of some showers and storms going tomorrow.

Winds will switch around out of the northeast tomorrow, and that will lead to some cooler temps.

Friday looks great with mainly dry conditions and highs in the 80s, and then the chances of showers and storms will ramp back up with time over the weekend.

Tropics...

Tropical Depression 4 has formed in the far eastern Atlantic, southwest of the Cape Verde Islands. There is a large subtropical ridge sprawled across the Atlantic, and that feature will likely keep the system on a track slightly north of due west through the weekend.

Most modeling would seem to indicate that this system will not eventually re-curve and might wind up threatening land down the road, but that's pretty deep into the crystal ball.

The system will have to battle a lot of dry air out over the Atlantic, so it will have an uphill battle regarding overly significant strengthening in the short-term.
