|***Permissive Burn Day ***
The upper low responsible for yesterday\'s scattered showers has moved south of our area, setting up a relatively strong pressure gradient from north to south as high pressure tries to rebuild. Expect northerly winds to increase by later this morning, reaching their peak by mid-afternoon. Wind speeds should remain near or below restricted criteria, so use plenty of caution if burning today.
24 Hour Outlook
***Permissive Burn Day ***
High pressure will continue to build over the state through the week, reaching its peak strength on Friday. Expect mainly light winds, warm afternoon temps, and deteriorating air quality through the forecast period. The ridge may weaken some by early next week.
