Cool Front Ushers in Drier Air

WAFB First Alert QuickCast:
- cool front moves through tonight
- lower humidity, mainly dry next couple of days
- rains return late in the week

Overall, it’s been a relatively mild summer locally, but we have seen a full dose of heat and humidity over the last several days. However, some relief is inching closer this evening in the form of a cool front.

Scattered showers and t-storms along the front as of early evening should begin to dissipate later tonight. The front slips through overnight and should be to the coast by the time most of us wake up on Tuesday morning. So, as you head out on Tuesday, you should notice a less muggy start to the day. And humidity will continue to drop through the day, making an otherwise warm afternoon feel a bit more comfortable than recent days.

I’m going with a mainly dry forecast for Tuesday and Wednesday as the front drops to the coast and drier air filters into most of the region. Afternoon highs will still be near or above 90°, but the much drier air should result in rather pleasant days by late July standards.

Dry weather doesn’t last long as an upper-air disturbance moves in from the northwest and interacts with the stalled front. Set rain chances around 30% by Thursday, with 50/50 chances from Friday into the weekend. A small silver lining is that high temperatures may remain a few degrees below normal into the weekend.

Finally, we’re tracking a rather healthy tropical disturbance well out in the Atlantic. The National Hurricane Center is giving the system a 50% chance of development within the next 2 days and a 70% chance of development within 5 days. Guidance indicates the system could be near the northern Lesser Antilles (eastern Caribbean) by Friday or Saturday, so we’ve still got *plenty* of time to monitor its progress.
