High pressure continues to sit over our region, bringing clear skies to the entire I-5 corridor. A thermal trough has developed to our south and its northern end has moved over Southern Oregon, leading to an offshore wind along the Coastline where temperatures have not dropped below 80 this morning.
Sunday afternoon Brookings Airport reached 92, and it’s likely Monday brings similar temperatures to Curry County. A heat advisory has been issued by the National Weather Service through 8pm this evening for the Coastline. The easterly winds are also raising fire weather concerns over Western Siskiyou County, where a fire weather watch has been issued for Monday evening through Tuesday morning.
A blocking pattern in the upper levels of our atmosphere will continue to drive any potential weather systems away from the Pacific Northwest, keeping us dry through the extended forecast. Tuesday will be the warmest day of the week, before highs gradually and very slowly start cooling. Even so, they will still remain above average temperatures for this time in September.
