745 FNUS55 KBYZ 160826 FWFBYZ Fire Weather Planning Forecast for SCen and SErn Montana National Weather Service Billings MT 226 AM MDT Thu May 16 2024 .DISCUSSION... We are into a Spring pattern across the Northern Rockies that will see good wetting rain chances and higher Min RH values (35 percent and higher) every other day through the weekend. In between days will be breezy with low wetting rain chances and RH values in the 25 to 35 percent range will be common. Today will be one of the low wetting rain chance days (under 20 percent) with westerly wind gusts of 20 to 30 mph in the afternoon and RH values of 25 to 35 percent. Tomorrow will have high wetting rain chances for central portions of the district (40 to 70 percent) with Min RH values over 35 percent for all but portions of Zone 133 (around 30 percent). Saturday will be a drier day, and Sunday will see another round of precipitation. This time of year the wetter days will see the potential for at least an isolated thunderstorm. Snow levels drop from 9500 feet Friday afternoon to 5000 feet Saturday morning, and stay under 7000 feet Saturday afternoon.
