Forecast Discussion: Current Conditions as of 2 PM on Wednesday: Drier air has moved into the region as expected, helping to end the showers across the region. While cloud cover held on long enough to limit ozone levels so far this afternoon, it is possible that some locations approach the moderate range on Thursday. *** Thursday’s Forecast: The next disturbance in this active pattern will approach the region on Thursday, but greatest chances for showers will remain to our south. With lower precipitation probabilities, the biggest question for the day will be the cloud cover. The trends in the models to keep the precipitation more to the south have also shown a decreasing trend in cloud cover. More sunshine will allow for concentrations to approach the moderate range, but enough high and mid-level clouds overhead for the day should keep ozone in the higher end of the good range. A few scattered low moderate readings are possible around the region, however. *** Extended Outlook: Chances for showers will continue late week and into the holiday weekend with the passing of additional disturbances. The winds on Friday will turn to more northerly and then easterly, pulling a cleaner air mass into the region. The onshore flow mixed with clouds and sunshine should continue to limit ozone to the good range. The best chance for moderate ozone readings may be early next week when a ridge of high pressure makes an appearance. A cold front with more showers and thunderstorms will arrive by the middle of the week, continuing to keep the pattern active. Temperatures will be seasonable over most of this period. --- Roble
