Discussion A dry cold front is approaching western montana and
central idaho this afternoon. Ahead of the front, dry and breezy
conditions will develop late this afternoon into the evening as
high pressure begins to flatten. The front will move through
tonight, likely maintaining breezy conditions, especially in the
higher terrain, into Saturday morning. This will be a critical
period for area wildfires due to the dry and breezy conditions.

The cold front will stall across southwest montana for Saturday.

Cooler temperatures are anticipated for most locations behind the
front, though breezy winds will continue, especially in the
vicinity of the stalled front.

The northern rockies will be under zonal (westerly) flow aloft
Sunday into Monday keeping temperatures slightly cooler then the
past several days. The models are indicating a weak disturbance
moving through this flow pattern late Sunday night into Monday
morning. This feature does have the potential of bringing partly
to mostly cloudy conditions to the northern rockies during the
solar eclipse. Moderate confidence on the exact timing and the
amount of moisture associated with the disturbance.

A ridge of high pressure rebounds over the northern rockies
Tuesday into Wednesday causing temperatures to warm. The ridge
axis shifts to the east by Thursday, putting the northern rockies
in a southwesterly flow pattern. This pattern is conducive to
increased convection potential. These storms could be on the dry
side due to how dry the low levels have been for the past week.

The models are hinting at another dry cold front moving through
the latter part of the week, but details are limited at this time.

Aviation Breezy westerly winds are anticipated to mix down to
valley floors late this afternoon and through the evening. These
winds will help dissipate wildfire smoke from affected terminals.

The winds will diminish in the late evening which could allow the
smoke to settle into area valleys once again. Kmso continues to be
the most impacted terminal for area smoke.

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.
