As we reach the summer solstice late Friday night (10:20 PM, to be exact), the weather will be seasonally appropriate. We can generally expect temperature in the low to mid-90s each afternoon after muggy starts in the mid-70s. Showers and thunderstorms will be possible particularly Friday and Saturday afternoons along and ahead of the seabreeze, though updrafts will struggle against high pressure building in aloft. In fact, we should generally see a lid on things for Sunday, making for a mostly sunny day. Heat indices will still run in the upper 90s to around 100°, so be sure you’re getting plenty of water and rest if you’re working or playing outside.
More heat and humidity are on tap for Thursday, but with a slightly better chance of storms in the afternoon especially as a front gets closer to the area. We’ll start the day in the mid-70s once again, warming back to the mid-90s in the afternoon. We’ll be keeping an eye on a line of thunderstorms to our northwest, which could help induce some stronger storms in the metro later in the afternoon through the evening hours. Damaging wind gusts would be the primary concern in the strongest storms, though the risk for severe weather is generally low (but not zero) across the area.
The rest of the work week will remain quite warm, especially Wednesday and Thursday as less in the way of showers and thunderstorms are expected before a trough of low pressure and accompanying front swing through to stir up more storms for Friday.
High pressure will continue to build in aloft, sending temperatures upward and storm chances downward. Tuesday will be another rather warm day, with lows in the mid-70s to start the day warming to the low 90s in the afternoon. Mix in dewpoints running in the low 70s, and that’ll yield heat indices right around the 100-101° mark during the height of the afternoon. Heat indices could even briefly spike in the immediate wake of the seabreeze as dewpoints surge before temperatures start to fall.
A storm or two will be possible along and ahead of the seabreeze, but with the capped atmosphere, it’s going to be tough to get much, if anything, to break through, much less sustain itself. Still, though, you can never completely rule it out this time of year.
The good news for this week’s weather is that we’ll see a bit more of a lid put on the atmosphere as we get into midweek, which should help to decrease the coverage of — but not eliminate completely — afternoon showers and thunderstorms. The tradeoff, though, is that it’s going to get hotter, with heat indices creeping toward 105° for the first time this year.
