Fire Weather Planning Forecast for SCen and SErn Montana
National Weather Service Billings MT
403 AM MDT Tue Jun 19 2018

.DISCUSSION...
More showers and thundestorms are expected across the area today
and Wednesday, continuing the wet pattern. The risk for the
heaviest rain has shifted into southeast Montana and northwest
South Dakota, where 2-3 inches of rain is possible over the next
24 to 48 hours over fire weather zone 133. Locally heavy rain is
still possible over the rest of southern Montana and northern
Wyoming, but coverage should be less compared to the last couple
of days, especially for western locations. Snow is again possible
above 9 thousand feet today and tonight. Warmer temperatures will
return for the end of the week into the weekend, but the chance
for more showers and thunderstorms will remain. TWH
