Area Forecast Discussion National Weather Service Boise ID 901 PM MDT Thu Jun 4 2020
DISCUSSION. Showers and thunderstorms continue to impact southeast Oregon this evening, with some activity starting to trail into extreme southwestern Idaho. Additional activity is favored, with more thunderstorms moving into the forecast area over the next hour or two. Activity is expected to weaken tonight ahead of the approaching area of low pressure scheduled to make a larger impact on the area Friday and Saturday. Will continue to evaluate storm progression this evening to ensure forecast remains generally on track. Forecast otherwise remains on track with hot temperatures anticipated across the valleys tomorrow.
AVIATION. VFR. Isolated thunderstorms across extreme SE Oregon tonight, then clearing. Showers and thunderstorms redeveloping across region after 21z/Fri near KTWF KJER and near KBKE KBNO. Storms may contain hail on Fri afternoon. Surface winds: variable 5-10kt becoming SW-SE 15-25kt on Fri afternoon. Gusty erratic winds in vicinity of t-storms up to 45kt. Winds aloft to 10kft MSL: SW 15-25kt.
Weekend Outlook . Intermittent showers expected Saturday, with widespread mountain obscuration and MVFR/IFR conditions developing by Saturday night. Snow levels drop to 5000-7000 feet MSL by Sunday with widespread precipitation and continued flight restrictions.
PREV DISCUSSION. SHORT TERM . Tonight through Saturday night . An isolated shower or thunderstorm is possible this evening in southern Malheur County. Otherwise, it will be mostly clear and mild. Our upper level flow will back to southwesterly tonight and remain that way until Saturday evening, as a strong upper low approaches from the northwest. This low will help bring moist and unstable air into the region tomorrow, setting the stage for showers and thunderstorms tomorrow from the late afternoon into the overnight hours. Some of these showers/storms will have strong gusty winds, with gusts to 50 mph possible. Temps will be hot tomorrow, with readings 15-20 degrees above normal. A cold front will move through Friday night into Saturday as the upper low gets close, and this will dramatically lower temps. Saturday's highs will be 25 to 30 degrees lower than Friday, resulting in readings 10-15 degrees below normal. Showers and thunderstorms will become numerous along and behind the front, with everyone likely to see precip Saturday. Showers, and isolated thunderstorms on the Idaho side, will continue Sat night as low temps fall to around 10 degrees below normal. Snow levels will fall to around 6000 feet in eastern Oregon late Saturday night, allowing snow to accumulate above around 6500 feet. Up to 2 inches are possible above 7500 feet by 6 am Sunday.
LONG TERM . Sunday through Thursday . The upper low is centered just to our west to begin this period brining widespread showers to the area. Afternoon thunderstorms can be expected Sunday with lingering instability associated with this low. Showers linger in the higher elevations Monday as this low exits the region. A second weaker trough pushes through Tuesday bringing showers to our northern zones. The GFS after this wants to bring another short wave through the region Wednesday afternoon while the ECMWF and Canadian both hold off until the next upper level trough to begin next weekend. Left in the mention of showers for the northern zones through Wednesday to account for this with a slight risk of thunderstorms for the higher elevations. Shower chances begin to increase throughout the day Thursday as our next upper level low starts to drop south from off the British Columbia coastline. Temperatures stay below normal through the weekend with Sunday still on track for lower valleys to experience up to 20 degrees below normal for high temperatures. A steady increase will follow with temperatures back above normal by Thursday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
