Area forecast discussion...updated 
National Weather Service Billings Montana
910 am MDT Wednesday Aug 27 2014

current forecast has things well in hand. No changes. Twh


Short term...valid for today and Thursday...

Dry zonal flow of air will be over Montana today through Thursday
and will provide plenty of sunshine and seasonal temperatures. An
upper low pressure system will be move slowly across southern
Wyoming today and Thursday but will have little impact on our
sensible weather. Did maintain an isolated chance of showers and
thunderstorms across extreme southern Sheridan County this
afternoon but did remove probability of precipitation over the southern areas of SC/southeast Montana.
Zonal flow will allow drier air to mix down today and Thursday
which will allow afternoon temperatures to reach the lower 80s
this afternoon and into the middle to upper 80s Thursday. Richmond

Long term...valid for Friday...Sat...sun...Mon...Tue...

Models continue to be in good agreement through most of the
extended period but do diverge quite a bit by the latter portions.
A mainly zonal flow aloft will be over the forecast area Friday
resulting in mostly dry conditions. However...a weak disturbance
will move across the northern portions of the state and this may
bring a shower or thunderstorm across the northern half of our
forecast area so have added a slight chance to account for this. A
strong trough and upper low move onto the Pacific northwest coast
Saturday morning and across the northern rockies late Saturday
into Monday. This will bring increasing chances for showers and
thunderstorms to the entire forecast area each day. In
addition...a cold front is prognosticated to sweep across the area during
the day Saturday resulting in gusty west to northwest winds and
cooler temperatures for Sunday and Monday. Models diverge quite a
bit by Tuesday into Wednesday so will not make any significant
changes to the forecast for those time periods. Hooley


VFR conditions will prevail today and tonight. However...note that
there is some chance of a shower or thunderstorm over the bighorns
with an attendant possibility of local mountain obscuration during
the afternoon and evening. Schultz
