... Flash Flood Watch remains in effect through Saturday morning...
The Flash Flood Watch continues for
* portions of northeast Oregon and southeast Oregon. This
includes the following in ... northeast Oregon... Baker County.
In southeast Oregon... Malheur County.
* Through Saturday morning.
* Moderate rainfall from showers and isolated thunderstorms
tonight through midday Saturday may be sufficient to trigger
mudslides/landslides in burn scar areas. The main burn scars
impacted will be the cornet/Windy Ridge and the Eldorado.
* Mudslides/landslides may occur suddenly and with surprising
force... blocking roads and potentially burying automobiles
rapidly. Highways in the burn scars... including US 26 and
State Highway 245... may become dangerous in periods of
moderate to heavy rainfall during the watch period.
A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.

Area forecast discussion National Weather Service Boise Idaho 853 PM MDT Friday Sep 4 2015 Discussion...scattered showers around the area have enhanced winds from a secondary cold front moving through. Gusty winds of around 40 miles per hour were reported at several sites this evening. Currently the front is located just east of Glenns Ferry and moving east. This feature is associated with a closed low that is still anticipated to move over the area overnight...keeping rain/snow chances in the forecast through Saturday...mainly in the mountains. Snow levels expected to drop to near 5500 feet in eastern Oregon and 6500-7000 feet elsewhere by Saturday morning. While quantitative precipitation forecast amounts have been low with these showers...repeated rainfall overnight into Saturday morning could add to the potential for mudslides or landslides. Therefore...Flash Flood Watch remains in effect for the burn scars in Baker and northern Malheur counties in Oregon. No changes made to the current forecast as probability of precipitation and temperatures still look representative. && Aviation...scattered-numerous showers will continue overnight... with isolated thunderstorms until 06z. VFR will prevail...but MVFR conditions are possible in the higher terrain. Mountains obscured. Cold front will continue to move through SW Idaho this evening...with gusts to 35 knots along the front. Northwest surface winds 15-25 knots behind the front this evening...diminishing to less than 15 knots after 06z. Winds aloft up to 10k feet mean sea level...SW 15-30 knots shifting to the northwest. Weekend outlook...low VFR and local MVFR ceilings with heavier showers can be expected Saturday...with isolated thunderstorms in the afternoon. VFR conditions Sunday with decreasing clouds and precipitation exiting to the east. Gusty westerly winds surface and aloft Saturday will weaken Saturday night and Sunday. && Previous discussion... short term...tonight through Sunday...a strong upper level low moving in from the west will impact our weather through the short term. The low was centered along the Oregon coast as of 2 PM MDT. This low will swing into eastern Oregon by 12z Saturday...then lift into northern Idaho by 00z Sunday. As it approaches this evening...all models indicate an increase in winds moving from west to east. This is an indication of a secondary cold front...possibly combined with an outflow from convection...that will bring gusty winds mainly to the southern half of our area. This increase in winds will move through southeast Oregon late this afternoon into early evening...arrive at Ontario between 6 and 7 PM...Boise between 8 and 9 PM...Mountain Home between 9 and 10 PM...and the western Magic Valley between 11 PM and midnight. Isolated brief gusts 30-40 miles per hour are possible...although generally gusts will be 20-30 miles per hour. Moderate rainfall is expected to be ongoing over eastern Oregon as of 00z...and as the low moves closer this rainfall could last overnight and through Sat morning. Therefore...a Flash Flood Watch has been issued for two burn scars in eastern Oregon...the Eldorado and the combined cornet/Windy Ridge. Rainfall amounts are not likely to cause problems outside of the burn scars. However... within the scars...mudslides/landslides are possible and these can be extremely dangerous. Please be aware if you will be traveling on U.S. Highway 26 through or near the Eldorado Pass...or on State Highway 245 south of Baker City. Saturday afternoon there is still a chance for showers and even a slight chance of thunderstorms over most of the area. Saturday evening the chance of showers and thunderstorms shifts significantly east as the upper low moves farther away. By late Saturday night...the showers will be confined to the west-central and Boise Mountains by Sunday afternoon...the chance of rain is gone. Temperatures will be cool tomorrow in the wake of the secondary cold front this evening...with highs in the lower to middle 60s in the lower valleys Saturday. Closer to the upper low...and with more clouds and precipitation...Baker City is not expected to get out of the 50s tomorrow. As the upper low moves away...we will see a 5 to 10 degree warmup for Sunday. Overnight lows tonight will be cool with middle 40s in the valleys...but will be even cooler Sunday morning...lower 40s in the valleys...as winds become light and we experience mostly clear skies. Long term...Sunday night through Friday...northwesterly flow will develop over the Pacific northwest for dry conditions through the remainder of the forecast period. A gradual warming trend is expected. Temperatures will be 5 to 10 degrees below normal Monday...warming back to near normal by Wednesday...and then going above normal Thursday and Friday. && Boi watches/warnings/advisories...
