440 WWUS83 KBIS 292045 RFWBIS URGENT - FIRE WEATHER MESSAGE National Weather Service Bismarck ND 345 PM CDT Sun Sep 29 2024 ...RED FLAG WARNING FOR MUCH OF CENTRAL AND PARTS OF SOUTHWEST NORTH DAKOTA THROUGH 10 PM CDT THIS EVENING... ...RED FLAG WARNING FOR MUCH OF WESTERN AND SOUTH CENTRAL NORTH DAKOTA TONIGHT THROUGH MONDAY AFTERNOON... .For today, record-breaking high temperatures in the 90s, afternoon relative humidity values in the 10 to 20 percent range, and strong southerly winds gusting to around 40 mph will combine to create critical fire weather conditions across much of central and parts of southwest North Dakota through this evening. Then for later tonight into Monday morning, a strong cold front will move across the state from west to east. This front will cause a wind shift to the northwest and increase gusts to around 45 to 50 mph along and behind the front. Even though this frontal passage is expected during nighttime hours, relative humidity is expected to remain lower than 35 percent through the night. Temperatures will be much cooler during the day Monday, but humidity in the 20 to 30 percent range combined with strong northwest winds will produce another period of critical fire weather conditions across much of south central and western North Dakota through the day Monday.

Area forecast discussion, Sep 29, 2:20 PM MDT, 25 minutes before
Area Forecast Discussion National Weather Service Bismarck ND 320 PM CDT Sun Sep 29 2024 .KEY MESSAGES... - Record-breaking heat expected across the western half of the state today, with highs in the 90s. Windy central and east, with winds increasing west to east tonight. - Critical fire weather conditions expected across much of central and parts of southwest North Dakota today, and across much of western and south central North Dakota tonight through Monday. - Much cooler with strong northwest winds on Monday. - Increasing potential for areas of frost across western North Dakota Monday night into Tuesday morning. && .DISCUSSION... Issued at 315 PM CDT Sun Sep 29 2024 Currently, upper ridge axis has shifted to the east as a well defined mid level S/WV moves onshore and advances inland across the far Pacific Northwest/Southwestern Canada. Associated sfc/mid level low has resulted in increasing southerly flow into the region, promoting strong WAA and unseasonably warm temperatures across the Dakotas. Boundary layer temperatures are at or above the 99th percentiles of climatology today, with record high temperatures already set at several locations across western and central ND. Coupled with strong moderate to strong mixing, afternoon relative humidity has fallen into the teens and 20s, resulting in critical fire weather conditions central and across parts of southwest ND. The Red Flag warning thus remains valid (See Fire Weather Discussion Below for more information). The aforementioned S/WV will continue east along far southern Canada/Northern Plains region tonight into Monday, and will drive a strong cold FROPA through the region later this Sunday evening through early Monday. Resultant weather will be northwest winds increasing west to east, along with much cooler temperatures surging into the region (Highs Monday upper 50s northwest - low 70s southern James Valley), around 20-35 degrees cooler than today. The main concern with the frontal passage remains strong wind and fire weather. Opted to issue a wind advisory across the entire CWA from 03Z this evening through the day Monday. Strongest winds will likely occur along and behind the FROPA tonight-Monday morning, where winds will gust to around 50 mph. BUFKIT soundings and ensemble probabilities are in agreement with warning criteria winds remaining aloft, but wouldn't be surprised to see a few +58 mph gusts late tonight/early Monday with the front. Very dry air will also accompany the frontal passage, and will result in another period of critical fire weather. Opted to upgrade the Fire Weather Watch for tonight/Monday to a Red Flag based on the projected Min humidity, strong northwest winds, and in collaboration with our neighbors. The Red Flag over western ND will start late tonight, while the Red Flag south central and for parts of the southwest will basically remain valid now through Monday. Again, see Fire Weather discussion below for details. A quasi-zonal flow pattern remains forecast for the remainder of the work week, with mainly dry weather conditions and temperatures more seasonal. The probabilities for morning frost and minimum temperatures dropping to around freezing continue to increase for Tuesday morning west, with another chance next week Friday morning. In addition, can't rule out more elevated fire weather concerns next week, as fuels cure and we see several dry and breezy days ahead. && .AVIATION /18Z TAFS THROUGH 18Z MONDAY/... Issued at 1250 PM CDT Sun Sep 29 2024 VFR conditions are expected through the forecast period. Southerly winds will be gusty across central and eastern North Dakota today, with sustained speeds around 20-25 kts and gusts around 30-35 kts. Winds will be more southwesterly and slightly weaker to the west, around 15 kts with gusts to 25 kts. Later tonight, a cold front will move across the state with winds switching to the northwest and increasing to 20-25 kts, with gusts up to 40 kts. Some low level wind shear will be possible tonight at various terminals, mainly east. && .FIRE WEATHER... Issued at 315 PM CDT Sun Sep 29 2024 Record-breaking high temperatures in the 90s reducing humidity this afternoon into the 10 to 20 percent range across western and most of central North Dakota. In addition, gusty southerly winds with sustained speeds around 20 to 30 mph and gusts to around 40 mph have been common central and east. Combination of these conditions results in critical fire weather, thus the Red Flag Warning remains in effect. Outside of the Red Flag Warning, which is in effect through this evening, near-critical fire weather conditions are expected. A strong cold front moves across the state late tonight through early Monday morning, bringing a reinforced shot of dry air. This will produce a unique setup where poor to very poor overnight RH recoveries will combine with the cold FROPA winds to produce nocturnal critical fire weather conditions west and sustain critical fire weather conditions south central. The expected wind shift from south to northwest will also support Red Flag conditions. Opted to upgrade the Fire Weather watch to a Red Flag, starting in the west late tonight, and keeping the Red Flag warning south central ongoing. Later shifts can adjust as needed. && .BIS WATCHES/WARNINGS/ADVISORIES...
