Forecasted AQI for Ozone Air Quality Index Scale Forecasted AQI for PM2.5
November 1, 2014

 

Date: Saturday, November 1, 2014
Action Day?:  No
Temperature:  Upper 40s to Near 50 Degrees
Discussion:
*** Saturday’s Forecast: Mostly cloudy conditions are expected on Saturday with the upper level disturbance from Friday now located off to our south and fueling a developing low pressure system off of the east coast. Winds will be a light breeze during the early morning hours, but will pick up in intensity throughout the day as this coastal system intensifies. PM 2.5 concentrations may see a few hours inside the low moderate range during the early hours of the day, but the dry and clean air that this coastal system will pull into the region as winds become stronger and more northerly will drop those values back into the good range. There is still limited moisture associated with this system that will only produce some light showers, most likely occurring in the morning to early afternoon. Temperatures will be limited to the upper 40s to near 50 degrees.

Extended:
*** Sunday’s Forecast: Sunday will be rather windy with strong northerly winds continuing to usher a clean and dry air mass into the region. Mostly cloudy conditions early will become increasingly sunny by the afternoon. Despite increasing sunshine, temperatures will remain below normal and at some of the coldest values we have seen so far this fall. The brisk flow will limit PM 2.5 concentrations to levels well inside the good range. High pressure will begin to build from the west by the evening hours as the coastal system moves further to the north and east. *** Monday’s Forecast: High pressure building over the region for Monday will help temperatures begin to rebound back to near normal values for early November. Winds will turn from northwesterly to more westerly with warmer air moving in aloft. This warm air aloft does not look to arrive early enough on Monday morning for there to be significant concern, but could certainly help PM 2.5 concentrations also begin to rebound. With quite a clean air mass in place after conditions on Sunday, some locations will take longer than others to see concentrations rise. Concentrations will reach values higher than that of Sunday, but only a few scattered moderate readings for the day are expected. *** Extended Forecast: High pressure will keep conditions dry and mild on Tuesday before the next cold front approaches for the second half of the week. Temperatures will be back above normal on Tuesday with moisture levels slowly continuing to rise. PM 2.5 concentrations should climb back into the moderate range for Tuesday and remain there for at least Wednesday and possibly Thursday. The timing and speed of the cold front over the second half of the week will be key in determining how quickly air quality conditions improve. --- Roble
