# HEADLINE -------------------- LOW FIRE DANGER # DETAILS -------------------- THE OUTLOOK FOR FRIDAY AFTERNOON The grassland fire danger index will reach the low category. ISSUED AT Thursday, July 2, 2026 at 2:09 AM CDT ISSUED BY National Weather Service Aberdeen SD HEADER Rangeland Fire Danger Statement # .DISCUSSION -------------------- Chances of showers and thunderstorms will remain in the forecast for the rest of the week. There is an enhanced risk (level 3 of 5) for some storms to become severe, with large hail and damaging winds as the main threat both this afternoon and evening as well as Friday afternoon and evening. The development of a tornado or two cannot be ruled out today. Winds will shift through the morning to be from the southeast while also increasing in strength. Areas over and east of the James River could see wind gusts up around 20 mph during the afternoon, while areas to the west could have wind gusts of 25 to 20 mph. Minimum relative humidity values this afternoon will be between 40 to 50 percent over central and northeastern South Dakota and west central Minnesota. Favorable weather conditions or a high moisture content of grasses, and other dry organic material on the ground, indicate that the probability of a fast moving fire is low. Outdoor burning under these conditions can usually be performed with reasonable safety precautions, but should be monitored. The outlook for Friday afternoon...The grassland fire danger index will reach the low category. # AREAS AFFECTED -------------------- Hamlin, Walworth, Big Stone, Brown, Buffalo, Campbell, Clark, Codington, Corson, Day, Deuel, Dewey, Edmunds, Faulk, Grant, Hand, Hughes, Hyde, Jones, Lyman, Marshall, McPherson, Potter, Roberts, Spink, Stanley, Sully, Traverse Including the cities of Wheaton, Ortonville, McIntosh, Herreid, Eureka, Aberdeen, Britton, Sisseton, Mobridge, Ipswich, Webster, Isabel, Gettysburg, Faulkton, Redfield, Clark, Watertown, Milbank, Hayti, Clear Lake, Fort Pierre, Onida, Pierre, Highmore, Miller, Murdo, Kennebec, and Fort Thompson

SD to WI Morning water vapor imagery shows several weak and/or convectively induced shortwave troughs moving across the northern Plains into the Upper Midwest. This area will have widespread marginal to moderate afternoon CAPE and dewpoints in the 60s to lower 70s. This leads to a forecast of a large area of potential thunderstorm development, but with weak/nebulous forcing and general height-rises aloft. As such, the overall confidence in this forecast is not very high. Storms are likely to focus along a boundary currently evident from southern SD into central IA. Convection currently developing in northern IA near the boundary should continue to intensify through the afternoon and track into southern WI/northern IL with a severe wind/hail threat. Other intense thunderstorm clusters are expected to develop along the SD/NE portion of the boundary by mid/late afternoon, also with a risk of large hail and damaging wind gusts. Western KS Full sunshine and dewpoints in the 60s will lead to a region of strong instability over western KS this afternoon. Most CAM solutions suggest at least isolated thunderstorms form along the KS/CO border and spread slowly eastward during the evening. A deeply mixed boundary layer and sufficient CAPE suggest a risk of damaging wind gusts in the strongest cells. TN Valley/Southern Appalachians A widespread very moist and unstable air mass is present today across this region, with full sunshine leading to steep low-level lapse rates and MLCAPE values over 4000 J/kg. Weak forcing under an upper ridge limits confidence in timing/location of storms. However, widely scattered thunderstorm development should eventually result in merging outflows and the risk of gusty/damaging winds this afternoon and early evening across the region.
