Each model's day runs midnight to midnight local time; models that reach fewer days are left blank. Rain: daily total. Wind: the day's highest average wind and, in small type, the strongest gust. Highlighted: values that stand out from the rest. The chance of rain comes from many runs of the same model with slightly different starting data.

UV index
Fri 30: 8 · Sat 31: 8 · Sun 1: 8
| Index | Level | What to do |
|---|---|---|

- ↘ Falling · now Anglers say fish feed more before the change
Falling now (−0.04 inHg in 3 hours). It barely changes over the next 48 hours. Falling pressure: anglers say fish feed more before the change. Fast changes, either way, tend to affect fishing.
