Short term Valid for tdy and sun...

upper low over northern utah is slowly swinging eastward through
the central rockies. This will shift its focus over the next 24
hrs from our western zones to the eastern zones. Currently, most
of the radar returns are across the central and west sections of
our cwa. Model proggs agree the upper dynamics will switch to the
east this morning after daybreak with what appears to be an
intense band developing from north central wyoming northeastward
to fallon county in eastern montana. Other eastern areas will
also see precipitation as isentropic lift in the low to mid levels
intensifies. In the west, precipitation will likely turn more
shower-type than drizzle by afternoon, and become scattered and
spotty as we head into the night.

The upper low remains rather stubborn and slow to move out. So
expect its influence to affect our eastern zones well into Sunday
as well with areas of light rain and drizzle. Light rain and snow
showers will slowly dwindle in the central and western zones
Sunday. We cannot rule out some precipitation over the east and
south even into Sunday night as the upper trough axis will be
moving over the area. However, any of this will be light and of
little impact. Temps will remain quite chilly this weekend,
requiring most to bundle up for outdoor activities.

Current winter storm warning for the southwest mountains expires
at 6 am. We are inclined to cancel it with the early morning
package as additional snow fall of an inch or two in the high
country will be limited and not likely render any additional
impacts. Bt

Long term Valid for mon... Tue... Wed... Thu... Fri...

for Monday into Monday night, an upper low will move
northeastward from wy to eastern mt. This low can produce some
rain mainly east of billings. Confidence in the precipitation is
not high due to the weak dynamics progged by the models... So have
pops around 30 percent at the moment. If rain does fall, it should
be light with amounts less than 0.1 inch.

The upper low exits mt on Tuesday... Leaving mt in a northwesterly
flow pattern Tuesday and Wednesday. There is a tiny chance of a
shower in this flow pattern but the chance is so small have left
the shower mention out of the forecast for the bulk of the area
for now. Best chance of a shower would be over the mountains.

Upper ridging dominates for Thursday and Friday with dry weather
expected across the region. High temperatures will rise from the
50s on Monday to the 60s for Tuesday through Friday to the lower
70s for Saturday. Rms

with MVFR to ifr CIGS and visibilities today.

Mountains will be obscured today. Rms

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.
