Tracking the breakdown of this heat dome

TODAY: Wednesday starts warm much like Tuesday. With temperatures starting in the low 70s and upper 60s, we have another setup for a summer-like day. Expect some cloud cover in our skies today, but not enough to cool us off. We likely climb to around 92 under partly cloudy skies. Dew points near 70 will make it feel like upper 90s.

TONIGHT: The muggy feeling continues overnight with temperatures holding in the low 70s tonight under mostly clear skies.

EXTENDED: The heat resumes on Thursday, but this time south wind speeds increase slightly, giving us about a degree or two advantage over Wednesday. Overall, a very similar feeling day, despite a slight drop in dewpoints. The heat doesn't break down until our next chance for storms that arrives on Friday. A cold front will push through the region around late morning and into the afternoon. This will bring the potential for a few strong storms. Any threat with these storms would largely be limited to an isolated hail and strong wind risk. The greatest impact will be the airmass reset that happens afterwards, with highs topping out in the mid-80s Friday, and low 80s Saturday. Showers will linger Saturday, before drier conditions during the latter half of the day. Sunday, we're as close to seasonal as we get in the 7 day forecast. Expect highs in the upper 70s, compared to our seasonal norm of 74. We climb slowly back into the 80s through the middle of next week.
