Possible Freezing Temperatures Coming This Weekend
The National Weather Service has issued a Special Weather Statement – Colder nights with possible freezing temperatures coming this weekend in southwest Washington and northwest Oregon. An early Autumn modified arctic air mass is descending into central and eastern Washington today. This dry and cooler air will set the stage for the coolest minimum temperatures of the season into early next week. Nighttime and early morning minimum temperatures could fall well into the 20s the next three or four nights. At this point the coldest nights look to be Saturday and Sunday nights. The one mitigating factor in some areas will be the strength and duration of the east winds. Areas where the winds remain throughout the night will tend to stay above freezing. Thus, some nights could see 15-20 degree ranges between the coldest and warmest areas and will make pinpointing low temperatures difficult. Precautionary/Preparedness actions: If you have plants susceptible to the cold be sure to take any necessary steps to protect them. You will likely want to disconnect outdoor hoses form faucets as well. For the most up to date weather information from the NWS please visit http://www.weather.gov/portland.
