522 FXUS65 KBYZ 211901 AFDBYZ Area Forecast Discussion National Weather Service Billings MT 101 PM MDT Sat Sep 21 2024 .DISCUSSION... Through Monday night... A quiet weather pattern expected for the next 48 hours. Residual low level cloud cover this afternoon will dissipate after 6pm, along with wind speeds. Can`t rule out patchy fog development for area river valleys after midnight. Frost potential also exists for area foothills and portions of SE Montana around sunrise, so make plans to protect tender vegitation tonight. Flow aloft tomorrow will be zonal and fairly light keeping skies mostly sunny and temperatures in the low-mid 70s. Sunday night a weak disturbance drops in from the northwest and pushes a dry cold front through the region. This feature will drop temperatures Monday afternoon to around the 70 degree mark and bring breezy to locally gusty northwest winds to the region. Chambers Tuesday through Saturday... Uneventful weather pattern continues for the extended period. Main sensible weather change will be temperatures warming into the mid-80s by Wednesday as a strong ridge aloft builds over the region. The warm temperatures look to persist into the end of the work week, though there is some hint that a Pacific cold front may make it into the area by Thursday afternoon taking the edge off of temperatures for Thu into the weekend (back into the 70s). Even the solutions showing the front moving in late week do not show much if any precipitation. Chambers && .AVIATION... VFR conditions will prevail through tonight. That said there are low chances (20-30percent) for fog development along area river valleys tonight. Have kept this mention out of TAF locations due to their elevated locations, but will keep an eye on this tonight. Northwest winds gusting 15 to 25 kts @18z over SE Montana will diminish through the afternoon. All areas will see light and variable winds around 00z this evening. Strata- Cu will lift from 3-4kft AGL to 5 to 7kft AGL as the afternoon goes on, with clear skies expected by 02z. Chambers && .PRELIMINARY POINT TEMP/POPS...
