Marine Weather and Tide Forecast for Days Creek, OR

DISCUSSION
Unusually warm temperatures mixed with some fire weather concerns are the main headlines in the forecast for today. The fire weather conditions are discussed in the Fire Weather section below. We set 6 temperature records yesterday with North Bend the only site missing out due to some onshore flow and coastal stratus.

The Extreme Forecast Index(EFI) continues to show widespread values of 1 today. This suggests the ECMWF ensemble members are all exceeding the model climatology in widespread areas. The 500 mb heights around 586dm are also in the extremes of climatology for this time of year in northern California. This will continue to result in daytime temperatures pushing 15 to 25 degrees above normal for mid March with multiple records potentially falling yet again today.

Alturas' record of 81 could be tied or perhaps fall.
Mount Shasta City's record of 74 will fall to a high around 82.
Montague's record of 77 will probably fall to a high around 79.
Medford's record of 81 could be tied or perhaps fall.
Klamath Falls' record of 72 will fall to a high around 76.
Roseburg's record of 81 will likely stand today as we're only forecasting a high of 76 up there. There will be some weak lift farther to the north in Central Oregon, so some high clouds could keep things a little cooler up there. There is also some stronger onshore flow there as well.

By Friday, the ridge begins to break down as 500 mb heights start to lower over Oregon and northern California. Even with the breakdown, we're still expecting some more temperature records to fall across the region. Eventually, a short wave and cold front will push into the forecast area around Saturday morning with a slight chance of rain. No wind, hydro, or winter impacts are anticipated with this frontal passage. Temperatures will trend cooler as relatively cooler air moves in behind the front.
Surprisingly enough, given the record-brekaing warmth of the last several days, we may see frost return to the West Side valleys, and a few areas could see freezing conditions, Saturday night into Sunday morning. Essentially, all the blooms we have seen recently are at risk of cold temperatures this weekend.

Monday will be a be a break between the systems before models want to spin up another low in the Pacific. The GFS low center still seems to be too far east compared to the ensemble range. In any case, the probability of precipitation forecast is around 60 to 80 percent Tuesday into Wednesday with snow levels dropping down to 4000 feet or lower behind the front. Don't count on a lot of snow with this system as only a few inches are anticipated in the Cascades. However, we will see another round of cold temperatures, with frost and freeze even more likely Wednesday night into Thursday morning.
