Earlier showers and thunderstorms today presage the passage of a warm front over the area. Behind this, high pressure begins to build tomorrow and persists through the end of the week. Temperatures during this stretch are likely to consistently reach into the upper-80s and low-90s in the city. As if on cue, the first full week of summer this year may also see a possible heat wave.

Rest of today – clouds gradually diminishing towards the evening. A few scattered showers still possible with a cold front forecast to move through later. High temperatures in the low-80s with cloud cover in place. Overnight lows will be mild in the low-70s.

Wednesday – relatively warm start to the day allows temperatures to climb into the low-90s in the city with the urban heat island effect. Mostly sunny skies with high pressure now in control. Overnight lows in the low-70s.

Thursday – high temperatures again into the low-90s with lots of sun. Luckily, the position of this particular high pressure doesn’t translate to the influx of a humid airmass, so the overall feel of these temperatures won’t be as muggy. Overnight lows in the low-70s.

Friday – yet another day of 90°F+ temperatures possible, which would mean an official heatwave. Still mostly sunny with high pressure remaining in control over sensible weather. Overnight lows continuing to be mild, in the mid-70s. Great beach weather!
