a quiet weather pattern in general expected for the next couple
of days across the forecast area. The upper low responsible for
the unsettled cyclonic flow aloft across the forecast area the
past several days will finally shift further east across the great
lakes today into Tuesday. This will allow the upper level ridge
and associated axis that has been over the pacific northwest the
past several days to slowly shift east over montana. As a result,
expect rising heights today into Tuesday as the ridge axis
positions itself over the state by Tuesday. Precipitation chances
will diminish across the plains with just a slight chance for a
shower or thunderstorm over the mountains and adjacent foothills
over the next couple of days. Temperatures will continue to warm
several degrees each day with readings above normal by Tuesday
when middle 70s will be common for most areas across the lower
elevations. Hooley

medium range models have come into much better alignment for late
in the week and into next weekend. The overall pattern looks
quite warm with limited precipitation chances. An upper ridge will
slide into the forecast area mid week with the ridge axis over
central montana Wednesday night. This will keep the area mainly
dry Wednesday and Wednesday night. The ridge axis slides east for
Thursday as a northern stream shortwave trough moves through. This
will generate a few showers and thundestorms. Shear increases
during this time, but CAPE does not look overly high. Could have a
few stronger storms though Thursday afternoon and evening with
increasing shear. Zonal flow with weak embedded waves will create
some instability for Friday and will keep low pops going then.

Heights try to build back into the area Saturday and Sunday as an
upper trough works into the pacific northwest.

Temperatures will steadily warm Wednesday and Thursday, with the
warmest day being Thursday. Added clouds on Thursday may limit
some of the warming, but latest guidance was indicating highs in
the mid to upper 80s were definitely reachable. Slightly cooler
readings for Friday through next weekend, but should remain above
seasonal levels with highs in the mid 70s to around 80 degrees.

With the above normal temperatures, an increase in snowmelt is
expected, causing flows to increase on area waterways by the end
of the week. Will continue to monitor this closely as the week
progresses. Twh

Aviation
Today will be less active with showers and thundestorms. Most
locations will be dry with just a few cumulus clouds developing
late morning into early afternoon. The best chance of a shower
will be over the high country and along the foothills. So,VFR
conditions are expected today. Winds will become a little gusty
this afternoon, with some gusts to 22kts possible at kmls. Twh

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.
