Area Forecast Discussion National Weather Service Missoula MT Issued by National Weather Service Spokane WA 330 AM MDT Tue Sep 29 2020

DISCUSSION. The remainder of the week into the weekend will feature a prolonged period of warm and dry weather. Our forecast has changed very little as the models continue to forecast a high amplitude ridge over the western U.S. High temperatures for western Montana and the southern Idaho Panhandle will run about 10 degrees above average through the weekend with our lowlands in the 70s and low 80s. Mainly clear skies and light winds will allow seasonably cool overnight lows. In general valleys above 2500 feet will have the potential for frost most mornings through the end of the week. Some valley fog will be possible as well the next several mornings.

We will be keeping an eye on the plume of smoke generated by the California wildfires. The HRRR Smoke model advects mid and high level smoke up the coast today and across Washington state and north Idaho on Wednesday. At this time, the model keeps much of the smoke aloft above a subsidence inversion roughly 5000-6000 feet above the surface. This scenario suggests that our skies will become milky or grey Wednesday into Thursday.

AVIATION. Mostly clear and calm conditions will prevail through the week. The only aviation impact will be a chance for some morning fog each day. Conditions will become more conducive to fog as the week progresses.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

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.
