FORECAST IN DETAIL

September was super warm and wet. To start October, we’ll hold onto the warmth but the pattern transitions to a dry one. We will have a couple of chances for showers this week, Tuesday and Friday, but most of the time it’s mostly clear and rain-free. Most days this week, if not every day, should hit at least 80 degrees, while the average high is now falling into the low 70s.

Tomorrow (Tuesday): This is another good-looking day for the most part as high temperatures aim for the low 80s. There is a touch of humidity, which may provide a bit of a juice for some widely scattered showers and thundershowers late in the day (30 percent chance). Confidence: Medium-High

Tomorrow night: A lingering evening shower or storm is possible. Otherwise, skies are partly cloudy as lows range through the 60s. Confidence: Medium-High

A LOOK AHEAD

Sunny, warm conditions prevail Wednesday and Thursday as temperatures remain well above normal. Highs both days range from 80 to 85 — about 10 degrees above average. It remains a little on the humid side and the moist air holds overnight lows in the 60s. Confidence: Medium-High

A weak front tries to push through the region Friday, and that may increase cloud cover a bit and introduce a small chance of showers. Still, it’s probably dry more often than not with highs near 80. Overnight lows settle in the 60s. Confidence: Medium

Summery conditions continue through the weekend. Under partly sunny skies and somewhat humid conditions, highs shoot for 80 to 85. Lows range through the 60s. Confidence: Medium
