Discussion Today will be a windy day across western montana. Cooler air will be crossing over the divide today. Increasing pressure gradients will result in strong east northeast winds. Wind gusts of 25-35 mph are expected this afternoon. The biggest impact from strengthening winds will be to flathead lake where 1-3 foot waves (locally higher) are expected this afternoon. Flood advisories continue at the clark fork near missoula where river levels above minor flood stage are forecast to continue through mid week. Otherwise other rivers across the region will be elevated but are not expected to reach flood stage. |
Much of the west will be stuck under a large trough through memorial weekend. Several closed lows are expected to rotate through this trough and keep the northern rockies in a cool and unsettled pattern. So expect scattered showers the entire week across parts of the nr. Under closed lows it is difficult to provide details several days out for location and amounts of precipitation however the theme for this week is cool and showery most every day.

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.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. |
