Hot and muggy to follow stormy days

The hottest days of the year so far are looming in the forecast - after a couple of days with possible thunderstorms.

And you know what rain followed by 90-degree heat means in Philadelphia: It will get muggy, too.

That could, however, mean a very nice weekend for the Shore.

Today should continue a nice streak - the fifth straight day with a high in the low to mid 80s.

But tomorrow will bring a darker mood, with thunderstorms very likely throughout the day, lowering the high back into 70s.

Thursday could have thunderstorms as well, though the odds are lower - 33 percent or less. The high should be about 79.

Then comes warmer weather.

If Friday hits 88, as expected, it would be the warmest day of the year, eclipsing the 87 reached on April 19.

Saturday could be just as hot, and Sunday and Monday are expected to reach into the low 90s.

It will be humid, too, with Saturday's dewpoint hitting the magic number of 65.

"The higher the dew point, the more moisture that is filling the air," Inquirer writer Tony Wood once explaining on a weather blog. "If it's 65 or better, odds are you're walking around in soup."

The Shore, though, should be a lot more comfortable, with highs in the low 80s and plenty of sun expected Saturday and Sunday.
