Update
High cloud is on the increase as clipper approaches from the
north. Pre-frontal air mass is quite dry (tfx 12z RAOB showed a
precipitable water of only 0.11 inches), and we will see afternoon
humidity in the teens along with gusty winds, and temps in the
vicinity of 70 degrees. Despite the dry air we should see isolated
showers with perhaps some lightning as pv MAX rotates through our
cwa this evening. Best chance of precip will be in our southern
upslope areas as post-frontal winds turn to the northwest. Have
adjusted winds up and dewpts rhs down for today. Have also
expanded isolated shower coverage across our east, per track of pv
max. Jkl

ridge over our region early this morning with mostly clear skies
across the cwa. There are a few locations with dewpoint
depressions under 3 degrees, so some local fog is possible by
sunrise. Our ridge will get broken down by a fast moving clipper
system tracking out of canada late today. Ahead of this system we
will see some increase in high cloudiness, but also downslope
winds and compressional warming producing much warmer temps than
yesterday. Isolated to scattered showers develop by early evening.

The best chance for measurable precipitation is along the north
facing slopes of the beartooths pryors bighorns. Some rain snow
mix is possible overnight in the higher foothills and mountains.

Precipitation quickly exits by Thursday leaving a sunny day with
temperatures mainly in the 60s. Bt

Long term Valid for fri... Sat... Sun... Mon... Tue...

dry and warm conditions are expected through the beginning of the
long term forecast. Expect temperatures in the mid to upper 70s
Friday afternoon with a ridge of high pressure in control of the
weather. Don't expect this pattern to last long, however, as a
large upper level low will move into the western united states
Saturday. Ahead of this upper level low, temperatures will be
quite warm on Saturday with many locations seeing their first 80
degree mark of the season. This low will move east through the
weekend bringing an increase in clouds, showers, and
thunderstorms. Temperatures cool slightly with increased clouds
and rain chances on Sunday but another warm day is still possible
in eastern montana along the dakotas border.

The upper level low finally moves over the forecast area into
Monday, but forecast differences are quite large at this time.

While there is a large spread in the guidance from Monday into
Wednesday, there is a signal for above normal precipitation
chances and cooler temperatures so the forecast keeps a mention of
precipitation well into the middle of next week. Dobbs

Aviation
Gusty sw-w winds will shift to the NW with a frontal passage late
this afternoon and early this evening. Expect gusts of 25-35 kts,
with some higher gusts possible along the foothills. In addition,
isolated showers and a few thunderstorms will occur along and a
few hours behind the frontal passage.VFR will prevail today and
tonight, but local MVFR is possible with the showers, and
mountains will be frequently obscured in rain snow showers this
evening. Jkl

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
