| Cautionary Comments: | ||||||||||||||||||
| *** WET Permissive Burn Day *** Front moving through the region already this morning has spread light amounts of rain across the valley. Persistent rains will continue mainly across the far NW and W sides through mid-day while the rest of the valley can expect a light shower or two for today with gradual clearing by afternoon. 24hr Outlook *** WET Permissive Burn Day *** Another weak wave will impact the area Monday into Tuesday with more light rains across the CA/OR border while the rest of the region will just remain cloudy and mild. Breezy North winds return midweek as high pressure returns and shunts all incoming storms well to the North for the last remaining days of January. |
