Area Forecast Discussion National Weather Service Bismarck ND 1248 AM CDT Tue Sep 10 2024 .KEY MESSAGES... - Isolated thunderstorms possible this evening through tonight. The threat for severe weather is low. - Areas of wildfire smoke returning to western and some central portions through tonight, and possibly linger into Tuesday. - Above normal temperatures through much of the week. - Greater chances for showers and thunderstorms (roughly 20 to 40 percent) return for the second half of the work week. - Breezy to windy conditions Wednesday through Friday. && .UPDATE... Issued at 1223 AM CDT Tue Sep 10 2024 A line of thunderstorms continues to push across south central North Dakota where there is still elevated CAPE aloft sustaining storms. Thunderstorms could produce small hail but severe weather is not expected. Near surface smoke continues to filter into western and portions of north central North Dakota. No updates are needed at this time as the forecast remains on track. UPDATE Issued at 1027 PM CDT Mon Sep 9 2024 Quick update for pops over the far south central. Nice cell over eastern Adams county has diminished a bit as it moved into wester Sioux and Grant counties. MUCape remains high just west of the Missouri River but Effective shear has diminished and CIN continues to increase. Will see if holds together. Elsewhere there are some pulses near Nelson Lake in Oliver county as well. Basically increased pops just west of the river through midnight. UPDATE Issued at 911 PM CDT Mon Sep 9 2024 The main forecast issue late this evening is thunderstorm chances. Latest satellite and radar imagery shows and area of convection from around Richardton and Hebron south to around Reeder, Hettinger and Lemmon. There was a stronger wind gust in Perkins County South Dakota a little earlier within an area of higher DCape. DCAPE over our area is not as high and as we go through the evening CIN continues to increase. We could still see a local stronger gust to 30-40 mph yet with this activity but that would likely be the extent of it, very local. As mentioned earlier, elevated CAPE remains over central ND through the night and there currently is some weak shear of 20-30 knots over central ND around the Highway 83 corridor, so it's possible we could see this current convection continue to bubble as it moves toward the Missouri River Valley, but with bases above 12kft and increasing CIN, the potential for much of anything reaching the ground, other than a local gust, appears low. We did try to add a bit more detail to the pops, which was tough as CAMS are having a hard time initializing and maintaining the weak convection. Basically a modified hourly broad brush through the overnight hours. Currently, lower visibilities due to smoke are over eastern Montana from around Miles City and Glendive, but are extending east to around Beach in far western ND. Expect some eastward progression to continue overnight. UPDATE Issued at 555 PM CDT Mon Sep 9 2024 Currently, upper level circulation was situated over northeast Montana with a surface trough situated over western North Dakota. Temperatures have climbed into the not to middle 90s over western ND. MLCape values are meager, around 500 J/KG over western ND but with steep low and mid level lapse rates. Moisture also remains limited until you reach around 550 MB. Inverted V soundings indicate a locally strong gust could be possible if convection could develop in the next few hours. Any organized convection would also be limited by little if any bulk shear. By mid evening (around 8 PM or so) increasing CIN should limit convection potential over western ND. Instability aloft remains over central ND through the late evening and overnight hours but the question will be whether the forcing for ascent will be strong enough for elevated convection. CAMS are not indicating much, but there are a couple that show some potential convection over the north central, which would be closer to the upper level impulse. Current pops take this into account and overall little chances early this evening. Only some minor adjustments to sky cover based on latest satellite imagery. Also did not make any changes regarding the increasing smoke from west to east tonight. Updated text products will be transmitted shortly. && .DISCUSSION... Issued at 335 PM CDT Mon Sep 9 2024 Upper level wave, currently in northern Montana, will move across the state tonight. An isolated thunderstorm is still possible as this wave moves through this evening through tonight. The overall threat for severe weather is low. There is a decent amount a MUCAPE through tonight, although 0 to 6 KM show is low and around 20 to 25 knots. Capping is also quite high through the night. Given the dry air in place, perhaps a strong wind gust is possible if any more developed storms can get going. Some CAMs do hint at little bit more activity in the Rugby area tonight, thus increased PoPs there, while maintaining slight PoPs elsewhere. CIMSS Natural Color Satellite RGB showing a wealth of smoke wrapped up in this disturbance. This is being supported by lower visibilities in MT. Expect this surface smoke to push into western and perhaps some central portions through tonight. Lows tonight will be in the 50s. RH values tonight are slow to rebound in the west at near 50 percent. Some eastern areas could see more than 90 percent RH. Perhaps some patchy fog is possible in the southern James River Valley once again. Confidence was not high enough to include at this time. The mentioned wave moves out of the area quickly Tuesday morning. Dry conditions will be found as a result. A weak surface front will push through. This will change the winds to a westerly component. Temperatures may cool to near 80 in the northwest as a result, yet remain in the mid 80s to mid 90s for most other areas. Wildfire smoke will remain aloft through the day and night Tuesday. Surface smoke will also linger through Tuesday morning, then retreat westward through the day and evening. Tuesday night is then mainly dry with perhaps some lingering smoke in the southwest. Temperatures will slightly cool into the upper 40s to upper 50s. Tuesdays front stalls then transitions to a warm front on Wednesday as a large Pacific Northwest low moves onshore. This will keep warm temperatures in the 80s to perhaps low 90s across the south, with cooler temperatures in the 70s to lower 80s north. Along this front could be a few isolated to scattered thunderstorms. A developing surface low lee of the Northern Rockies will also bring some breezy southerly winds for Wednesday. The upper low moves further inland for Thursday, strengthening the developing surface low to our west. The warm southerly flow will bring 80s to lower 90s for temperatures, while winds become breezy to windy. Depending on location of the strongest winds, perhaps some elevated fire weather concerns are possible with these increasing winds and continued warm temperatures on Wednesday and Thursday. ECMWF EFI wind gusts values also remain elevated Wednesday through Friday, and especially on Thursday. This could be a hint that advisory level winds are possible. This wave then still looks to push through sometime Thursday night through Friday night. This will bring better chances for showers and thunderstorms, continued breezy to windy conditions, and slightly cooler temperatures. CSU-MLP still indicating isolated severe weather is possible Wednesday through Friday, although remains dependent on instability as shear values look high. The upcoming weekend then looks to be in a transitional pattern ahead of another potential large trough pattern. Look for the resultant west to southwest flow aloft to bring near to perhaps slightly above average temperatures. Winds should go on a diminishing trend given the more relaxed surface gradient. Precipitation chances also look minimal for the upcoming weekend as drier air moves into the area. Although perhaps some isolated shower or thunderstorms activity may linger in eastern North Dakota on Saturday. && .AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/... Issued at 1223 AM CDT Tue Sep 10 2024 VFR conditions will continue through the period. Winds will continue to veer from southerly to northerly by the afternoon. A line of thunderstorms continues to move across the southern half of the state. Thunderstorms should be out of the area by sunrise and may only impact KJMS later this morning. && .BIS WATCHES/WARNINGS/ADVISORIES... None. && UPDATE...Johnson DISCUSSION...Anglin AVIATION...Johnson
