Forecast Discussion: Pollution levels from the weekend thru today have remained good, with hourly readings reaching moderate levels on Saturday for PM2.5. Tuesday morning will be the coldest of the period, with temperatures in the upper 30’s in the central regions and lower to mid-40’s in the southern regions, with highs region 60-65 throughout the forecast area. Skies will be mostly sunny. Winds will be out of the north and northwest at 5-8 mph. Wednesday morning will not be as cold. High temperatures look to be about a degree or two higher than Tuesday’s highs. Winds will be out of the north at 5-10 mph. Skies will be partly cloudy. Winds will increase to 10-15 mph on Thursday as a low pressure system moves south out of Canada. Very little moisture appears to be available for this system, so no rain and very little cloud development are expected, keeping skies mostly to partly sunny. High temperatures will be about the same as Tuesday and Wednesday.
