Widespread freezing temperatures across much of western montana. Of note will be the lower valleys of northwest montana and the bitterroot missoula valleys. Some of these areas have reached the freezing mark however tonight's freeze will be more widespread and potentially freezing for several hours rather than just briefly touching 32 degrees. Overnight lows may lower into the mid 20s in portions of the bitterroot valley. Temperatures may not quite make it to freezing in the camas prairie but will lower enough to produce widespread frost with low temperatures in the mid 30s. Dry conditions will prevail through much of this week. Temperatures will continue to be well below normal through Tuesday under a light northerly flow on the lee side of a developing ridge of high pressure. The ridge will finally establish itself over the region |
by mid week and temperatures will return to near normal. It's looking like the ridge breaks down late in the week or next weekend and westerly winds will increase under a zonal flow. The potential for precipitation will increase under this pattern. As is par for the course there is a lot of uncertainty for any kind of details of precip location or amounts.

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. |
