Update: Does Heat Wave End With a Bang?

If storms develop today, they could be strong or severe

*Severe Thunderstorm Watch in effect until 10 p.m.*
*Heat Advisory in effect through 8 p.m.*

Temperatures: At the noon hour, temperatures were in the low to mid 90s and rising across the metro area. Highs this afternoon should max out in the mid to upper 90s, and a few spots could reach the 100-degree mark. Heat indices are already around 100 and are on their way to near 105.

Chance of storms: Most likely timing for storms is late afternoon through evening, between 4 p.m. and 11 p.m., with a chance of some isolated activity earlier and some storminess possibly lingering to the east after. The 6 p.m. to 9 p.m. window is when the strongest storms could come through, if they develop.

It certainly won't rain during the entire late afternoon and evening. And there's a chance that storms won't materialize at all, or will be limited in coverage or focused north and northeast of the area. But keep in mind that more often than not, extreme heat waves end with a bang not a whimper.

Severe potential: Any storms that do form have the potential to develop rapidly and become severe. The Storm Prediction Center has placed the metro area on the southern end of a moderate risk for severe storms. Along with lightning and heavy downpours, the biggest threats look to be damaging winds and large hail. Tornadoes aren't out of the question, but chances are higher to the north and northeast in Pennsylvania, New York and Vermont.

Stay tuned for updates. Meanwhile, the end of the heat wave is in sight. See our full forecast through the weekend.
