Tillamook Area Forecast
December 6, 2019
A large upper level low pressure area is off to the west of northern California and its associated cold front is ahead of the low and will impact our area later this afternoon. It is expected that as the front gets closer, it will also slow down and weaken, so, we can expect rain, mainly some light rain though we will still see some periods of enhance rain as embedded disturbances rotate through in the flow. The rain will persist through tonight and into tomorrow. During this time the large low pressure area will also be weakening.
The low will finally drift into northern California tomorrow afternoon so most of the energy will be pushed into that area, but we likely still see some scattered showers move through our area as well. High temperatures today and tomorrow continue in the low 50s, lows in the low 40s.
So, Sunday, a high pressure ridge moves in which dries things out, except for some patchy morning fog and by Monday we see mostly sunny skies, highs near the mid 50s but nighttime lows near the mid 30s.
Tuesday the models show the ridge moving off to the east as another weakening front approaches the area, bringing back a chance of rain then the model guidance becomes less reliable. It appears we will have a zonal or west to east flow over the area which would suggest an active weather pattern meaning we have a chance of rain each day, for much of next week. For now, we are just not sure exactly when or how much. Highs remain in the mid 50s, lows back in the low to mid 40s.
