463 FXUS65 KBYZ 220809 AFDBYZ Area Forecast Discussion National Weather Service Billings MT 209 AM MDT Sun Sep 22 2024 .DISCUSSION... Through Monday night... Dewpoint depressions are rather narrow out in the east and northwest zones, so we cannot rule out patchy fog development for area river valleys or our far eastern counties early this morning. Otherwise, look for mostly sunny skies today, but increasing high clouds late. Highs will be around normal in the lower to mid 70s. Tonight we will see height falls associated with a trough moving across Canada. This will push a weak front through the region late tonight through Monday morning. Low level moisture is lacking and downslope flow will prevail, so we do not expect much more than sprinkles at best for most areas behind the frontal passage. However, we added (over model guidance) a slight chance of showers over the east Monday morning as the trough axis does strengthen just a bit as it moves into the high plains. Look for temperatures Monday to be just a bit cooler than today with breezy to locally gusty northwest winds (15-25 mph gusts). BT Tuesday through Sunday... Benign weather will persist for much of the extended forecast period. Warmer than normal temperatures associated with upper ridging will be the main story. High temperatures will climb into the mid-80s, Wednesday and Thursday. Models are hinting that a cold front may pass through the region, Thursday afternoon. The result of this would only be a cool down of temperatures, back into the 70s, Friday through the weekend. The chance for precipitation throughout the extended forecast is very low. Matos && .AVIATION... VFR is expected to persist through the period. Low chance of patchy fog near most of the TAF sites this morning. Matos && .PRELIMINARY POINT TEMP/POPS...
