FORECAST SUMMARY:
Monday, March 2nd, 2020 through Monday, March 9th, 2020
PM-2.5: 24-hour Fine Particulate concentrations will range between Good and low Moderate through the forecast period.
FORECAST DISCUSSION:
On and off weather systems will pass generally north of the state this week. Precipitation is in the forecast; however, the best chance arrives with the Thursday system. After each tracks east, winds turn northwesterly for a time helping to keep fine particulate from increasing significantly. There will be periods of transition between systems with lighter winds; for instance, weak winds Wednesday may allow for a mix of Good and Moderate fine particulate. Another time frame for possible Moderates will be Saturday as high pressure settles overhead briefly.
For the week, we are expecting a mix of Good to low Moderate fine particulate.
EXTENDED FORECAST:
Extended forecast models show a stronger storms system approaching by Monday of next week. For the weekend, stronger southwesterly winds develop late Saturday into Sunday. The stronger flow should keep fine particulate from increasing; however, warmer winds over some snow in the northern portion of the state may cause some Moderate readings.
