AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1053 PM MDT Wed Jul 30 2014

UPDATE TO AVIATION

.UPDATE...
Current radar imagery shows three areas of showers and a few weak
thunderstorms: northwest Glacier County, including Babb and northern
parts of Glacier NP; a disjointed band extending from Lincoln/Helena
through central Cascade/Judith Basin counties to southern Blaine
County; and from Butte to Monida.  With the sun now setting,
convective activity will continue to dissipate over next few hours,
and we`ll see gradually clearing skies across the region for the
overnight hours.  Expect a repeat of conditions tomorrow with high
temperatures in the mid 90s and scattered aftn/eve showers and
thunderstorms.

.DISCUSSION...
Tonight through Wednesday...a rather simple summer like forecast
expected over the next week. Overall...very warm temperatures and
isolated/scattered thunderstorms are expected across the entire
region over the next week. An upper level ridge of high pressure
will be over the region...with weak upper level
disturbances/monsoonal moisture moving through the region. Thus
isolated/scattered thunderstorms are possible each day...with the
best chance for any thunderstorms occurring over the Rocky Mountain
Front and Southwest MT. Temperatures will remain on the very
warm/hot side through the period...with any cooling of afternoon
temperatures being very minimal. Brusda

.AVIATION...
UPDATED 05Z.
VFR conditions will prevail through this TAF period. Isolated
showers and thunderstorms will develop and move across the area
Thursday afternoon until sunset when thermal convection will cut off
any overnight precipitation potential. Ceilings and visibilities may
drop briefly near any shower or thunderstorm...that may also produce
gusty erratic winds. Suk
