DISCUSSION

Still by in large a persistence forecast as we head into Saturday. Patchy fog may develop in spots early today. Lows in the early morning continue to increase slightly with each day, now expected in the 70s area wide. Mid/upper level ridging continues to dominate with onshore flow remaining in place at the surface. Rain chances are slim to none today with CAMs keeping the area dry. Highs should reach the 80s to lower 90s with heat indices in the 90s to triple digits. Be mindful of the heat and make sure to stay hydrated, especially as we head deeper into the summer months.

Sunday is poised to be another warm day with slim to none rain chances. Heading into next week, several impulses may undercut the mid/upper level ridge. This, along with decreasing subsidence plus building moisture should result in daily chances for showers and storms throughout next week. Highs are forecasted to remain in the 80s/lower 90s with lows in the upper 60s/lower 70s. Heat indices remain generally around the 90s to triple digits, easing down slightly during the later half of the week.
