FORECAST SUMMARY:
Monday, November 9th, 2020 through Monday, November 16th, 2020
PM-2.5: 24-hour average Fine Particulate concentrations will also be mostly Moderate early in the week then mostly Good for the remainder of the forecast period.
FORECAST DISCUSSION
Unseasonably warm weather will persist through Tuesday before a cold front will return the region back to more seasonable temperatures. Until then, we will likely see temperatures in the low 70’s during Monday and Tuesday then dropping some 20 degrees cooler on Wednesday. Southerly winds during Monday and Tuesday will likely keep conditions Moderate until the Wednesday morning cleanout.
Cleaner, colder air will filter in Wednesday morning and bring Good Air Quality back to the region. High pressure will accompany the cleaner air mass which will slowly drift eastward Wednesday and Thursday. We will briefly get back into a southerly air flow Thursday before the next front Friday morning. High pressure returns for the weekend and continued Good Air Quality.
Southerly winds briefly return during Sunday before the next cold front Sunday night.
With these series of frequent fronts followed by cleanouts, I anticipate mostly Good Air Quality from Wednesday through next Monday.
EXTENDED FORECAST:
Air Quality should be mostly Good going into next week.
