Forecast Discussion: Current Conditions: An unseasonably strong upper level trough is pulling cooler than normal air southward into the region as of 1 p.m. EDT this Monday afternoon. The current radar shows showers and thunderstorms developing across northern parts of the state, and some of those might survive into our area late this afternoon and this evening. Temperatures this afternoon will not top 80 in some spots, with a gusty west to northwest wind. Plenty of mixing and cloud development this afternoon will keep fine particulate and ozone down in the good range. Partly cloudy, breezy and cool tonight with showers ending. Low temperatures dropping into the upper 50s. *** Tuesday's forecast: Continued unseasonably cool on Tuesday with temperatures remaining in the middle 70s, which is almost 10 degrees below normal for late July. Both ozone and fine particulate concentrations will continue to be in the good range. Turning out mostly clear and quite cool Tuesday night with low temperatures falling into the lower 50s in the cooler spots. *** Extended forecast: We should have one more day of good air quality on Wednesday with high pressure building in and winds dropping off. There is the chance for a late day shower or thunderstorm as a weak weather system rotates out of the Great Lakes. Clouds and possible shower development Wednesday should keep ozone levels low, and the air might still have too much dryness in it to bring PM to the moderate range. Afternoon temperatures only near 80 degrees. As the high becomes nearly stationary later this week, it will promote light winds. Increasing moisture coming up from the south will send PM into the lower moderate range. With more sunshine and warmth Thursday, ozone also has a chance to go moderate. Moderate air quality should continue for the most part at the end of week with light to at times calm winds as well as sunshine and building humidity. There is also increasing chances for afternoon showers and a thunderstorm as we head into the weekend. Temperatures will slowly get back towards normal as we move into the upcoming weekend.--McAuliffe
