PM Update: Summer solstice brings more 90s
Hot, increasingly humid, through mid-week; then more heat
The first day of summer has brought with it our second official (3 days 90+ or more) heat wave of the season. And you better like it, because we'll be adding at least a handful more days to this streak it would appear. Highs reaching near 90 and into the lower 90s this afternoon are a touch cooler than yesterday but still above normal for this time of year. The outlook for the rest of the week varies between hot and really hot with just a few opportunities for cooling showers and storms.
Through Tonight: The best thing about summer around here is the decent evenings it can produce. This will be a warm one, though not too bad as temperatures fall through the mid-80s near sunset. We stay mostly clear overnight, but as the high pressure drifts offshore, humidity levels should begin to rise by morning. Temperatures bottom out in the mid-60s in the cooler spots to the lower 70s in the warm ones.
Tomorrow (Tuesday): Plenty of sunshine will help temperatures quickly jump into and through the 80s during the morning. By late afternoon, readings rise to the low 90s many spots, with perhaps a few mid-90s mixed in as well. Winds from the south or southeast will make it considerably more humid than today. Late day we'll have to watch for an isolated storm and the potential for more development heading into the evening or overnight, though it looks like most will stay to our north.
Eyes on the tropics: A tropical wave has become better organized in the Caribbean today and has been declared an "invest" by the National Hurricane Center. The NHC currently gives the system a 30 percent chance of developing in the next 48 hours, though the likelihood of such has grown recently. Forecasted conditions appear to be fairly favorable for strengthening in the coming days should the system continue to organize. Several models place the system in the Gulf of Mexico around next weekend, but it's much too early to say where or if this will happen.
