Forecast Discussion: *** Saturday’s Forecast: Mostly sunny skies with temperatures approaching the 60 degree mark will start the Presidents Day weekend off with conditions more like something we would expect for Memorial Day weekend than mid to late February. With temperatures falling into the low 30s overnight into Saturday morning with warm air sitting aloft, PM-2.5 concentrations are expected to climb into the moderate range early and remain there for the day. Winds will be light and out of the southwest for most of the day before becoming breezy during the evening as a weak cold front passes with no precipitation expected. *** Sunday’s Forecast: High pressure will begin to build back over the region on Sunday with the unseasonably mild conditions continuing. Temperatures will again climb to near 60 degrees with a west to northwesterly breeze. PM-2.5 concentrations may fall slightly compared to values from Saturday, but should still remain at moderate levels for at least a few locations. *** Monday’s Forecast: The west to northwesterly flow from Sunday will turn more northerly on Monday, knocking high temperatures down a few degrees from the values over the weekend but will still remain unseasonably mild. Highs for the day will be in the low 50s under mostly sunny skies. Most sites will see PM-2.5 concentrations fall into the higher end of the good range, but a few scattered moderate readings are still possible. *** Tuesday’s Forecast: On Tuesday, onshore flow that will become more southerly later in the day will help to provide some increasing cloud cover to shield the sunshine. As a result, temperatures, though again still mild, will be held to the mid to upper 40s as highs. Chances for precipitation look to remain relatively slim, though may increase over the evening hours. PM-2.5 concentrations will climb slightly from levels on Monday, resulting in more moderate readings on average for the day. *** Extended Outlook: Our next best chance for any precipitation will arrive on Wednesday at the earliest. The string of mild temperatures will continue with highs returning to the 50s on Wednesday and hanging around for at least a few days after. Without a big change in air mass or enough mixing from the breezy conditions, PM-2.5 concentrations may continue to remain at moderate levels. --- Roble
