Marine Weather and Tide Forecast for Robie Creek, ID

SHORT TERM /Through Monday Night/
The area will stay under the dry side of an upper trough digging over the Pacific northwest coast. This pattern will bring an elevated southwest flow and a dry slot over our area. As such, hot, dry, and breezy conditions will continue today through early week.
Critical fire weather conditions remain through the evening today, with very low relative humidities in the single digits/lower teens and windy conditions expected this afternoon, especially over southeast OR and higher terrain of southwest ID. Lingering monsoon moisture will slowly get eroded away by the dry slot. The Magic Valley will see scattered thunderstorms in the afternoon today, some capable of producing gusts 40-50 mph and brief heavy downpours.
Westerly flow today will allow for northwest winds to develop through the Baker Valley corridor to Ontario this evening and Sunday evening with gusts in exposed areas up to 40 mph. This will help to bring smoke over central OR down the Baker Valley into the Snake Basin both days as well. New large fires in eastern OR and Owyhees will also contribute to increased smoke.
Temperatures are expected to cool down to seasonal normals Sunday and Monday. Sunday and Monday will generally see lower afternoon wind gusts.

LONG TERM /Tuesday through Saturday/
Our area will remain under the strong high pressure system building off of the Four Corners region through the extended period. Monsoonal moisture influx will mainly stay south and east of our area, leading to hot, dry, and breezy conditions throughout the long-term period. Temperatures will generally stay near normal Tuesday through Wednesday. By the end of the week , the Four Corners high will begin to shift west and amplify over the Great Basin, allowing for a warming trend to 5 degrees above normal come Thursday and Friday. Saturday may see a dry cold frontal passage that could return temperatures to near normal.
