First 90-Degree High of 2014 Headed to DC

Temperatures are forecast to make a run at 90 F Tuesday, ahead of a push of cooler air from the Atlantic Ocean.

Higher humidity will once again create uncomfortable sticky conditions.

The steamy weather will also set the stage for a couple of thunderstorms to develop Tuesday afternoon, mainly north of the nation's capital.

If temperatures hit 90 on Tuesday, it will be the first such temperature reading of the season and the warmest day since Oct. 6.

In the wake of Tuesday's storminess, how far south the front sinks will determine whether a noticeably cooler and cloudy Wednesday unfolds versus another warm day.

As a front approaches from the Midwest Thursday night and Friday, it may join forces with tropical moisture moving northward.

According to Senior Meteorologist Alex Sosnowski, "If the two fully get together and the forward speed of the front slows, there is the potential for incidents of flash and urban flooding."

In the wake of the front this weekend, cooler and more seasonable air will settle in, but there is the chance of showers and thunderstorms, mainly during the afternoon and evening hours.
