DAYS 1-5 (SEPTEMBER 7-11)
High pressure builds as upper level low pressure departs, resulting in fair, pleasant weather for today. While many folks use this as a travel day and not a day to enjoy, at least the weather favors travel! Our nice weather will continue on Tuesday even though a weak trough will scoot through the region with some clouds. You’ll find it a bit warmer than today. The outlook remains the same heading into midweek with a low pressure area set to move east southeast in a northwesterly flow aloft. This will cloud us up on Wednesday with episodes of showery weather Wednesday night and Thursday. This system exits by Friday and high pressure builds in that day with fair weather returning. A humidity spike accompanies Thursday’s unsettled weather, but it will be short-lived when a batch of dry air follows it quickly on Friday.
