FORECAST
TODAY
After a round of rainfall last night, we’ll see a break in the action this morning. Then, as the sun energizes the atmosphere this afternoon, random, pop-up downpours will develop (30%). Severe weather is not expected, but gusty winds and minor street flooding are possible with any storm. Meantime, humidity will allow heat index values to return to the mid-90s.

HOW MUCH RAIN?
The nature of this activity makes putting a blanket total on the forecast very tricky. Like last night, some may see nothing, others more than an 1″. It’s the luck of the draw, but if we’re putting numbers to it -- most will see less than 0.50″.
