Forecast Discussion: Current Conditions as of 1 PM on Monday: Temperatures have returned to near normal values this afternoon, though humidity remains at lower and more comfortable levels. A clean air mass in place has both ozone and PM-2.5 concentrations inside the good range this afternoon, but we should see one of those turn to more moderate levels as early this week as tomorrow. Unsettled weather will continue this week with daily chances for at least isolated showers/thunderstorms. *** Tuesday’s Forecast: Unsettled weather continues on Tuesday with chances for showers and thunderstorms throughout the day. Moisture levels rising, helped by southerly flow, will increase humidity levels as dew point temperatures climb. PM-2.5 concentrations are expected to climb into the moderate range, but the breezy southerly flow and periods of rain will limit how high these values climb. Peaks of sunshine are possible, but enough cloud cover will hang around to keep ozone levels inside the good range. Highs for the day will be in the upper 70s, slightly below normal for late June. *** Extended Outlook: A wet June comes to a close, but July does not start out any drier. The pattern will remain unchanged throughout the week, keeping a threat for daily showers and thunderstorms likely even through the holiday weekend. PM-2.5 concentrations will stay near moderate levels through most of the week with some brief periods of improvement, mainly after heavier showers move through. Ozone, however, will be limited to the good range nearly all week with the daily cloud cover mixed with some sunshine and chances for precipitation. Highs for the week will remain slightly below normal with values approaching the 80 degree mark daily. --- Roble
