Fire Weather Planning Forecast for Wrn Montana and N Cntrl Idaho
National Weather Service Missoula MT
446 AM MDT THU JUL 30 2015

...Hot, very low RHs, and strengthening Thermal Belts through
Sunday...

...Increasing Potential for thunderstorms next Monday through Wednesday...

.DISCUSSION...

Idaho: Strong high pressure begins to build today and will peak
this weekend. Temperatures will be very hot: into the mid 100s in
the Lower Hells Canyon and other lower valleys of Central Idaho.
In addition, these areas can expect very low daytime min RH
values (in the single digits to lower teens), and poor recoveries
at night under strong inversions through Sunday.

A change in the overall pattern begins Sunday night. Low pressure
will develop off the west coast, with increasing southwesterly flow
gradually ushering in monsoonal moisture. Increasing instability
will produce a few thunderstorms late Sunday night through Monday
night. Chances of afternoon and night time thunderstorms increase
Tuesday and Wednesday as additional moisture enters the region.
Confidence is increasing for thunderstorm development, but not as
high for coverage or intensity of storms.


Montana: Strong high pressure will encompass the region today
through the weekend. Temperatures will be very hot by Friday, and
peak on Sunday. Expect valley temperatures in the mid to upper
90s, with a few areas in the lower valleys in the Kootenai, west
Lolo and Bitterroot approaching 100 Saturday and Sunday. In
addition, expect very low daytime min RH values (in the single
digits to mid teens), and poor recoveries at night under strong
inversions through Sunday.

A change in the overall pattern begins Sunday night. Low pressure
will develop off the west coast, increasing moist southwesterly flow
and instability to bring a potential for thunderstorms in the
Beaverhead/Deerlodge and southern Bitterroots Sunday night and
Monday. Confidence is increasing that thunderstorms will spread
across all of western Montana Monday night through Wednesday. It`s
also looking like storms may last through the night in some areas.
While confidence is increasing for storm development, it is not as
high for amount of coverage or intensity of storms. Stay tuned.
