.KEY MESSAGES...

- Increasing shower and thunderstorm potential for the weekend.
  Heavy rain possible, but severe storms are unlikely.

&&

.UPDATE...

Scattered showers and a few weak thunderstorms remain over
central and eastern Montana this evening. As atmospheric
conditions becoming less favorable for these showers and
thunderstorms over the next few hours, expect this activity to
decrease in coverage before coming to an end tonight when surface
high pressure builds over the area. Low temperatures tonight will
be in the 40s to lower 50s. LA

.DISCUSSION...

Today through next Thursday...

Energy under persistent northwest flow will continue to provide
scattered showers and isolated thunderstorms this afternoon and
evening. The main activity will be across the plains for areas
Billings east through around 9pm MDT. Subsidence will move in
tonight providing a warm and dry day for Friday. Into Saturday,
shortwave troughing will move across southern MT and northern WY.
With ensembles splitting the energy into northern MT and northern
WY, the best chances for precipitation will be across the higher
terrain and southeast MT. Additionally, southerly low level flow
is expected to increase atmospheric moisture, with pwats at
1-1.2" across southeast MT. This will aid in higher precipitation
amounts. Currently there is about a 50-80% chance for at least a
half an inch of precipitation with about a 20-50% chance for an
inch over southeast MT this weekend. With modest instability and
shear also in play, strong thunderstorms have the potential to
produce heavy rainfall. Thunderstorms are not expected to be
severe at this time. With ensembles showing that northern wave
moving south and east through Monday, small to moderate
precipitation chances will remain in the forecast. Ensembles then
return the region to ridging or back to northwest flow by mid week.
High temperatures through the period will generally be in the 70s
to low 80s. TS

.AVIATION...

VFR conditions are expected through the TAF period. This evening,
scattered showers and isolated thunderstorms will continue to
move through central and eastern Montana. With this, airfields
around KMLS, KBHK, and K97M could see brief gusty winds and
reduced visibility under moderate rain. Surface high pressure then
builds over the area tonight into Friday allowing dry conditions
to prevail. Friday, breezy easterly winds are expected to develop
over the plains of south- central Montana. LA
