Forecast Discussion: Current Conditions as of 1 PM on Tuesday: While most of the precipitation is staying to our south, some showers have already pushed north into parts of the forecast zone over the past few hours. High pressure will build starting on Wednesday as this system pushes out to sea. After a reprieve of the higher humidity Wednesday, a return of warm and humid air will return along with potential for deteriorating air quality for the weekend. *** Wednesday’s Forecast: High pressure will build over the region on Wednesday as a weak cold front that sat to our north on Tuesday dips southward. Winds will be a light breeze out of the north, which should provide our best air quality conditions across the region for the week. Unfortunately, these best conditions may only be both PM 2.5 and Ozone falling into the high end of the good range. A mix of sun and clouds as the high pressure builds will combine with the arrival of some cleaner and drier air from the north to limit Ozone formation. This cleaner and drier air will also help lower PM 2.5 concentrations back into the good range. Locations that received rainfall on Tuesday may see PM 2.5 levels elevated into the moderate range early on Wednesday, but should fall to high good with the clearing throughout the remainder of the day. Highs are expected to reach the mid to upper 70s. *** Extended Forecast: The reprieve from the heat and humidity will be short lived as the high shifts more to our south and east and continues to strengthen on Thursday. Winds will begin the day as more northerly before a shift to more south/southwesterly by the afternoon. Light recirculation of the localized air mass may climb back into the low moderate range in some locations, especially for Ozone concentrations. As low level moisture begins to rise once again, PM 2.5 concentrations are also expected to rise. We may not see a rise early enough in the day for the daily average to climb above high good levels. Clearing skies with a strengthening high pressure could push Ozone concentrations into the moderate range if enough primary pollutants are around to assist in the Ozone formation process. Temperatures are likely to return to the low 80s. Light winds and mostly sunny skies look to be in store for Friday and the upcoming weekend. With temperatures pushing into the mid to upper 80s and dew point temperatures back into the 60s, hazy, hot, and humid conditions will prevail. Moderate air quality appears to be likely with a chance that we may see Code Orange levels as well. We will keep an eye on how conditions develop over the next two days to see how high concentrations may climb along with the temperatures for the weekend. --- Roble |
