Looking Ahead

ARTICLE CONTINUES BELOW AD

The prevailing warm and humid conditions will continue as light and variable winds are expected through early next week with afternoon heat index values approaching 100 degrees at lower elevations. Increasing showers are forecasted Thursday through Saturday as moisture associated with Jimena and an upper level disturbance approaching from the northwest combine to bring another round of unsettled weather. Locally heavy downpours and potential for flooding exists from Thursday afternoon and possibly into the weekend.
