Short term Valid for Sat and sun...

an upper trough will pass over southeastern montana this evening,
bringing about enough forcing to help initiate another round of
storms. Ample instability and moisture will be present, but a lack
of shear will result in slow moving storms popping up and down.

There's good agreement of pwats around 1.3 inches, so localized
heavy rain and possible flash flooding are the main concerns, on
top of small hail and damaging winds. The main areas of concern
are fallon and carter counties, and storms will be focused during
the evening hours between 800 pm and 100 am. Temperatures will
reach the low 80s today.

Going into Saturday, a weak shortwave will pass over the area
ahead of a strong upper jet. Although there will be a relative lack
of moisture and instability, a combination of upslope winds, ample
shear, and upper level divergence may bring about an isolated
chance for severe storms at, north, and east of billings.

Temperatures will briefly warm up for Saturday, reaching the low
90s.

For Sunday, zonal flow aloft will shift to the northwest, and the
passing of another cold front will help bring about cooler than
average temperatures, with highs back in the low 80s, and drier
conditions.

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

a weak wave will drop into the area in northwest flow on Monday
bringing isolated to scattered showers and thunderstorms to mainly
northern and eastern areas. Otherwise, dry northwest flow will
limit precipitation chances through much of the upcoming work week
along with keeping temperatures below normal. Another wave
dropping into the region Thursday night and Friday could bring
some showers and thunderstorms. Ridging begins to build over the
northern rockies for next weekend bringing warmer temperatures.

High temperatures are forecast in the 70s for most areas through
the long term. Low temperatures in the 40s and lower 50s are
forecast most nights mornings. Stp

Aviation
Scattered showers and thunderstorms will develop over the southern
mountains and adjacent foothills this afternoon and evening as
well as southeast montana. The shower thunderstorm activity will
gradually diminish into the overnight hours. In general,VFR will
prevail with brief reductions in thunderstorm activity. Mountains
will be occasionally obscured. Some of the storms east of a kmls
to kshr line could be strong to severe with large hail, wind gusts
to 50kts and heavy rain. Patchy fog and localized reductions are
possible over portions of far southeast montana late tonight. Stp

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.
