Marine Weather and Tide Forecast for Robie Creek, ID

SHORT TERM /Through Saturday Night/
Weak mountain snow/rain showers with minimal accumulations are expected to continue through the evening today. Strong northwest winds with gusts up to 50 mph remain over the Upper Treasure Valley, Western Magic Valley, and Camas Prairie through the evening and a Wind Advisory remains in effect for these areas through 8pm MST. Elsewhere, breezy conditions will persist through the afternoon before winds begin to decrease after sunset.

An upper level ridge begins to build over the region Friday, shifting our flow to the north-northwest. Friday's temperatures will generally remain similar to today's in staying on the cooler side, with much drier conditions expected. The ridge shifts further east on Saturday, bringing a warming trend. A weak shortwave moving around the top of the ridge will bring an increase in high clouds throughout the day. Upper moisture steered in by this shortwave will bring a 20-40% chance of light snow/rain showers over the west-central ID mountains and near Baker County, OR Friday through early Saturday. Otherwise, the region can expect a dry start to the weekend with temperatures returning to 5 degrees above normal.

LONG TERM /Sunday through Thursday/
A ridge of high pressure will build into the West Coast this weekend, bringing above normal temperatures and mostly dry conditions on Sunday and Monday. Northerly flow aloft will help push moisture into the West Central Mountains and Baker County, bringing a 20-40% chance of light showers Sunday and Monday. A cold front will move through the region late Monday, bringing much cooler temperatures, gusty winds, and mountain snow (30-50% chance).
Valleys look to remain dry, with minor snow accumulations over the mountains. The region will be sandwiched between a large upper level trough to our north and a broad Pacific High, keeping us in zonal flow with a tight pressure gradient for most of the work week.

The active and unsettled pattern will remain through next week as a few embedded shortwaves move through the region. Intermittent pushes of moisture will accompany these shortwaves, increasing cloud cover and chances of light precipitation through Thursday. The best chance for precipitation will be over high terrain in southwest Idaho, with higher elevations seeing a 40-60% chance of precipitation each day Tuesday-Thursday. As the Pacific High pushes onshore next week, temperatures will gradually warm back to slightly above normal.
