Area Forecast Discussion National Weather Service Boise ID 916 AM MDT Tue Aug 11 2020
DISCUSSION. Main concern continues to be isolated thunderstorms this afternoon and evening south of Rome/OR to Mountain Home to Fairfield. Latest HRRR model shows outflow winds reaching those locations from thunderstorms to the south. Gusts 40 to 50 mph. Today will be about 5 degrees warmer than yesterday. Cold front Wednesday looks stronger than it did yesterday. Front expected in eastern Oregon midday and western Idaho in the afternoon. High temps Wednesday will lower 8 to 15 degrees in Oregon and 4 to 8 degrees in Idaho, with several degrees further cooling Thursday. No rain is forecast with the front but post-frontal west winds will increase in all areas Wednesday. A Fire Weather Watch has been recently issued for the Owyhee Mountains for Wednesday afternoon and evening for wind and low relative humidity. Current forecast looks good. No updates.
AVIATION. VFR. Isolated showers and thunderstorms this afternoon mainly south of a KREO-KMUO-KSUN line. Surface winds: variable 10kt in the Snake Plain, SW 10-20 kt elsewhere after 20Z. Thunderstorms may produce gusty erratic winds up to 50kt. Winds aloft at 10k feet MSL: W-SW 10-20 kt increasing to W-SW 25-35kt by 12z/Wed.
PREV DISCUSSION. SHORT TERM . Today through Thursday night . Dry westerly winds aloft for much of the area today then a shift to west-southwest as an upper level trough begins to dip into the area. This west- southwest flow will bring a bit of moisture into the area allowing for areas of showers and afternoon thunderstorms for portions of our CWA near the Nevada border. High-res models are indicating a more northern extent in this push, but will keep the current forecast as is. A cold-front associated with this trough will make its way through the CWA Wednesday bringing cooler temperatures and breezy conditions. Not much in the way of precipitation with this system. Thursday will see drier conditions once more with temperatures still lingering below normal.
LONG TERM . Friday through Tuesday . West-northwest flow Friday and Saturday will remain dry and start a warming trend across the region. An upper high centered over the Desert Southwest will expand northward on Sunday bringing further warming. Model solutions in better agreement tonight on the initial surge of heat for Sun/Mon with the ridge axis extending through ID. While much of the period will be dry, will need to keep an eye on potential moisture working into the region on Monday. Though continued hot beyond Monday, seeing a larger spread in temperatures in response to timing differences of a trough approaching the Pac NW coast. Sunday and Monday are the warmest days of the period with temperatures around 10 degrees above normal which will put lower valley locations around 100.
BOI WATCHES/WARNINGS/ADVISORIES. ID . Fire Weather Watch from Wednesday afternoon through Wednesday afternoon through Wednesday evening IDZ423. OR . None.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
