Forecast Discussion: Updated Thursday, October 23, 2014 10 a.m. Afternoon high temperatures will rise towards and approach record levels by Friday and Saturday before dropping on Sunday and early next week. A Pacific Northwest trough will move through the area late on Sunday/Monday and bring breezy conditions. The bulk of the storm system will stay well to our north and so the winds won’t be quite that strong along with no precipitation expected locally. So with the breezy conditions not expected to be that strong on Sunday/Monday and temperature inversions not expected to be significant, the PM10 AQI forecast levels (excluding Cowtown) will be in the good to low/mid moderate range on the AQI scale into the upcoming weekend and early next week.
