Forecast Discussion: Current Conditions: At 2 p.m. EDT this Wednesday afternoon, a strong area of low pressure was located along the New Jersey coast. This low will only slowly move to the northeast over the next couple of days, and this will allow for gusty north to northwest winds and low levels of fine particulate. For tonight, expect brisk and chilly conditions with a mostly cloudy sky. A couple of showers are also likely. *** Thursday's forecast: Windy and cool on Thursday with low pressure off the east coast continuing to have an influence on our weather. Good mixing and ventilation will keep fine particulate concentrations low. Afternoon temperatures in the middle and upper 50s. Partly to mostly cloudy Thursday night with continued gusty northerly winds. *** Extended forecast: Our weather will remain dry as we head into the upcoming weekend. Winds averaging from the west and northwest will continue to bring good air quality. A little warming is also expected to occur with more in the way of sunshine. A weak frontal boundary will cross the region late Saturday, but will likely not produce any precipitation. High pressure then builds in Sunday into Monday with temperatures averaging close to normal. Winds should turn into the southwest early next week, and this may cause some increases in PM concentrations. Another cold front will then move in for later Tuesday into Wednesday of next week.---McAuliffe
