Forecast Discussion: Current Conditions: At 2 p.m. EDT this Monday afternoon, high pressure is bringing partly sunny and very warm conditions to the region. With higher humidity and smoke coming eastward from wildfires in the western U.S., fine particulate is well into the moderate range. The sun is still strong enough to bring ozone levels into the moderate range. Warmer than normal temperatures are expected to continue for most of this week, and ozone production will be elevated. Mostly clear tonight with low temperatures only falling into the middle and upper 60s. *** Tuesday's forecast: Sunshine and a few clouds Tuesday with another very warm afternoon. Ozone concentrations will rise well into the moderate range. Fine particulate will also be in the high moderate range. Afternoon temperatures will reach the upper 80s. *** Extended forecast: Cool air coming in aloft on Wednesday may kick off a couple of showers or a thunderstorm late in the day, so ozone production will be limited to the lower moderate range. Fine particulate will linger in the middle moderate range with winds continuing to be on the light side. A cool front coming through on Thursday will bring a scattering of afternoon showers and a thunderstorm. Ozone production will not rise above the lower moderate zone. High pressure then builds in behind this front for Friday and Saturday, and with a cleaner air mass, upper good to low moderate levels of PM2.5 and ozone are expected.---McAuliffe
