Mild and dry weather will continue through the end of the week

weekend...however with the main axis pushing east of the region,
southwesterly flow aloft will develop. Despite this more active

toward the start of the work week with split flow developing, so
have dropped pops to slight chance. Above average temps are also
expected to continue through early next week.
