Pasture near Deville was dry dirt when it would normally offer green, ankle to shin high grass for livestock at this time of year. A cattle operation had gotten 60% less hay than usual after getting just one cut of hay. The sale barn in Mansura has sold twice the usual number of cattle since the start of the year. The cattle weigh less than they should. KALB-TV (Alexandria, La.), Aug 23, 2023

Residents of Allen were urged to voluntarily conserve water. The Southwest Allen Parish Water District was seeking emergency conservation for the entire system as the water supply was low from increased water demand for firefighting as more blazes were sparking amid the hot, dry conditions. The water supply was low and not keeping pace with firefighters’ demand. There has been an uptick in wildfires in the Oakdale area. American Press (Lake Charles, La.), Aug 22, 2023

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0358 PM CDT Wed Aug 23 2023 Valid 251200Z - 311200Z An upper ridge will slowly meander westward from the Plains states toward the Rockies as an upper trough amplifies over the eastern CONUS through the remainder of this week into early next week. Broad upper troughing will also prevail across the Pacific Northwest into next week, with the possibility of a more pronounced, progressive mid-level trough overspreading the region sometime after the upcoming weekend. Amid the aforementioned synoptic pattern/evolution, two primary areas of concern exist. Prolonged hot conditions (with RH dipping into the 20-35 percent range by afternoon peak heating) will persist each day across the south-central CONUS, with little beneficial rainfall in the forecast. Though differences in timing exist in medium-range guidance, there is a consensus among the GFS and ECMWF in the passage of a cold front across the southern Plains into the lower Mississippi Valley sometime in the Days 6-8/Monday-Wednesday period. Current indications are that this front may be dry, accompanied by little (if any) rainfall, breezy northwesterly surface flow, and fairly dry low-level air. Given highly receptive fuels, Critical conditions may occur, and Critical probabilities may be added in future outlooks pending model agreement in the timing of frontal passage. Across the Pacific Northwest, west of the Cascades, appreciable widespread rainfall has been largely absent, and is expected to remain so into next week. Fuels west of the Cascades are highly receptive to wildfire spread, supportive of efficient fire ignitions for any lightning that occurs away from soaking rain. Multiple instances of showers and thunderstorms are possible across the Pacific Northwest late this week into the weekend. However, questions remain regarding coverage, especially west of the Cascades, given scant buoyancy. As such, dry thunderstorm probabilities/highlights may be added in future outlooks if details regarding the timing of thunderstorm development and available buoyancy are resolved. ..Squitieri.. 08/23/2023 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 2029 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR NORTHWEST/NORTH-CENTRAL ND
Mesoscale Discussion 2029 NWS Storm Prediction Center Norman OK 0343 PM CDT Wed Aug 23 2023 Areas affected...Northwest/North-Central ND Concerning...Severe potential...Watch possible Valid 232043Z - 232315Z Probability of Watch Issuance...60 percent SUMMARY...Isolated supercells are possible this afternoon and evening across northwest/north-central ND. Primary severe risks with any mature storms are large hail and damaging gusts. DISCUSSION...Recent surface analysis places a low in far northwest ND, approximately 50 miles north of ISN. Visible satellite shows some deeper cumulus in the vicinity of this low, with some additional shallower cumulus ahead of it. The air mass across the region continues to destabilize amid strong heating and dewpoints in the upper 60s/low 70s. Recent mesoanalysis estimates MLCAPE is near 1500 J/kg just downstream of the surface low. Moderate mid-level flow stretches across this region as well, which is contributing to moderate/strong vertical shear. Recent mesoanalysis estimates effective bulk shear around 40-45 kt is currently in place. This moderate mid-level flow and associated moderate/strong shear is expected to persist across the region through the evening. Given these environmental conditions, a conditional risk of a supercell or two exists. Main uncertainty is whether or not updrafts can be maintained amid the potential entrainment of moderately warm and dry mid-level air. Current expectation is that at least a few storms should be able to persist, although, given the subtle forcing, it could be a few hours before updrafts are able to mature. Any storms that do mature/persist would likely become supercellular with a subsequent risk for large hail and/or damaging gusts. ..Mosier/Grams.. 08/23/2023 ...Please see www.spc.noaa.gov for graphic product...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0256 PM CDT Wed Aug 23 2023 Valid 232000Z - 241200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS LOWER GREAT LAKES...NORTHERN NORTH DAKOTA... ...SUMMARY... Scattered damaging winds and large hail, and a tornado or two will be possible across parts of the Lower Great Lakes and northern North Dakota, centered on this evening into tonight. ...Discussion... Only minor changes were made to the previous convective outlook. 1) Extension of 5-percent and 15-percent wind probabilities farther south into southeast OH and WV. The 12z NSSL WRF had the best depiction of storm activity across eastern OH compared to other 12z CAMS and recent HRRR runs. The northerly flow across the upper OH Valley will aid in storm motions to the south. Some moisture advection into eastern OH in the 925-850 mb layer will act to destabilize the airmass downstream of the ongoing storms in eastern OH. 2) Remove a tier of counties in northern Lower MI from 5-percent hail probabilities. A considerable spatial extent of stratus will likely be maintained across northern Lower MI and this will likely limit overall destabilization and the hail risk. ..Smith.. 08/23/2023 .PREV DISCUSSION... /ISSUED 1128 AM CDT Wed Aug 23 2023/ ...Lower Great Lakes... A relatively low confidence but conditionally favorable environment for severe storms is expected through tonight with above-average spread in potential outcomes from minimal coverage to a mesoscale-focused swath of fairly numerous reports. Elevated convection is ongoing across eastern Lower MI to southern ON. This may not entirely decay during the afternoon, with a threat for isolated, marginally severe hail and strong wind gusts potentially persisting southeastward in eastern OH/western PA. To the west, a very unstable air mass will gradually advect east across much of southern Lower MI through western OH in tandem with an EML expanding from the Upper Midwest. A substantial baroclinic zone supported by pronounced differential boundary-layer heating will yield a sizable thermal gradient across the northwest to southeast-oriented warm front. The surface warm sector should remain capped but there are a few models, namely the 12Z ARW-NSSL and 00Z ECMWF which suggest convection should develop along the warm front and into the warm sector. The more probable scenario is for regenerative elevated convection to increase again after sunset. Forecast soundings suggest that deep-layer flow may remain relatively constant with height near the warm front which would limit cloud-bearing shear, with more favorable deep-layer shear farther east coincident with lesser instability. As such, a cluster convective mode will likely dominate with relatively equal threats for large hail and damaging winds. ...ND... An MCV over southeast SK will move east across southern MB into northwest ON tonight. While the bulk of convection attendant to this MCV may remain north of the international border, trailing development into ND will become increasingly likely towards early evening along the apex of a differential boundary-layer heating corridor centered over central ND. There should be favorable zone for a couple supercells across a portion of north-central to northeast ND within the MLCAPE/CIN gradient that should orient from northwest to southeast. Large hail, isolated severe wind gusts, and a tornado or two will be possible during the evening before convection tends to weaken overnight closer to the Red River Valley. Read more

Brownwood was in Stage 2 water restrictions as Lake Brownwood was 8 feet below the spillway on Aug. 23. The lake was at 65.8% capacity, compared to 66.6% one week ago. People were urged to pray for rain. Brownwood News (Texas), Aug 23, 2023

Firefighters battled blazes in at least four spots around Spokane County and neighboring counties on Friday, Aug. 18. Strong winds drove the fires, which caused the deaths of two people, one southwest of Spokane and the other north of the city. Heat, dry vegetation, drought and wind combined made the fires difficult to extinguish. Rainfall has been half of normal since May at the Spokane International Airport.

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1253 PM CDT Wed Aug 23 2023 Valid 241200Z - 251200Z Elevated highlights were added to portions of northern Montana, where a surface cold front will sweep across the state while a mid-level trough traverses the international border. Along and behind the cold front, RH may drop into the 15-20 percent range as widespread 15+ mph sustained northwesterly surface winds overspread fine fuels that are becoming receptive to wildfire spread. Isolated dry thunderstorm highlights have also been added to the Oregon/California border region, where an embedded mid-level impulse will promote deep-layer ascent amid a marginally buoyant airmass. Thunderstorm coverage should be quite sparse. However, any thunderstorms that develop will be fast-moving, and will pass over highly receptive fuels which have missed the benefits of recent rainfall from TC Hilary. ..Squitieri.. 08/23/2023 .PREV DISCUSSION... /ISSUED 0158 AM CDT Wed Aug 23 2023/ ...Synopsis... Within the base of a closed midlevel low off the Pacific Northwest coast, an embedded shortwave impulse should lift north-northeastward across OR during the evening/overnight hours. The related large-scale ascent and gradually increasing midlevel moisture/instability could support isolated thunderstorm development. While lightning-induced ignitions cannot be ruled out with any storms that develop over dry fuels, weak instability casts uncertainty on storm coverage and the overall risk -- precluding an Isolated Dry Thunderstorm area at this time. Farther east, boundary-layer mixing into a belt of enhanced deep-layer westerly flow over northern MT could favor dry/breezy conditions during the afternoon. While locally elevated fire-weather conditions are possible, recent rainfall could limit the overall risk. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
