DISCUSSION.

Increased cloudiness and passing nuisance rain showers will continue across the Northern Rockies through this evening. Rain amounts will be quite insignificant, with the possible exception of the Glacier Park Region. Otherwise conditions will be mild and occasionally breezy through sunset.

Southwest flow aloft will develop over the Northern Rockies on Friday, pumping warm air northward across the region. Friday daytime temperatures will be more than 10 degrees warmer than today for many locations. Late in the afternoon, showers and thunderstorms will begin emerging near the triple point of Oregon, Washington, Idaho borders. These showers and thunderstorms are projected to increase in coverage and intensity along a surface cold front that will march eastward throughout the evening and overnight. Some high-resolution models suggest that thunderstorms will be passing through locales such as Kalispell in the wee hours of Saturday morning. Despite the nocturnal nature of these storms, plenty of lightning, brief heavy rainfall, erratic wind gusts, and small hail are probable. Many details are likely to shift and change over the next 36 hours, so stay aware.

Showers and thunderstorms along and ahead of a cold front will continue to march east across the Northern Rockies on Saturday. There is a reasonable amount of spread among models in the timing of the cold front across southwest Montana during Saturday. Late morning through mid-afternoon appears to be the most plausible time of the cold front passing across the Continental Divide. Outside of the usual thunderstorm attributes, it is unclear how strong wind gusts and how large hail may become. Stay tuned.

Temperatures will cool appreciably across the Northern Rockies Saturday through Monday, with widespread rain and high elevation snow developing. First, snow could become a hazard for those traveling or recreating above 6000 feet Sunday night through Monday morning. Even beyond snow accumulation, the lack of traction on typically passable backcountry roadways, low visibility, and risk of hypothermia in heavy, wet snow will be risks during this time. Take time to consider how to endure winter weather conditions such as these in your travel plans. Also, near-record cold daytime temperatures may be present on Monday.

Cold air will remain in-place across the Northern Rockies through Tuesday. Tuesday morning temperatures will cool to near freezing for many valley locations (if skies clear accordingly).

Most long-range models suggest that relatively warm high pressure will move over the Northern Rockies Tuesday and Wednesday. Some models also suggest that a jet streak overhead may increase cloudiness, particularly on Wednesday. Temperatures are expected to warm near the seasonal average during this time.

AVIATION. Breezy conditions will continue across the Northern Rockies through 05/0300Z with gusts up to 25 knots being possible across area terminals. Cloud cover will gradually decrease this evening and tonight as a ridge of high pressure builds across the area. A round of showers and thunderstorms are possible late Friday afternoon and evening across northwest Montana and north central Idaho as a cold front moves into eastern Washington.

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.
