Southeast winds will increase throughout the day today east of Rosebud County as a surface pressure gradient tightens and 850 mb winds increase into the 30-40 knot range. 30-45 mph wind gusts are expected with the strongest winds being near the Dakotas border. Winds will peak Friday afternoon and early evening before leveling off in the 30s mph Friday night and Saturday. Winds are expected to decrease Saturday evening.
Above average high temperatures in the 50s and 60s F and dry conditions are expected through Monday. There is increasing confidence in a pattern change for the middle to late week period. There is a 30-50% chance for getting greater than 0.25 inches of precipitation. Temperatures are also expected to decrease to more seasonable values in the 40s F. Details such as precipitation type and the potential locations of the heaviest precipitation are not known at this time. Torgerson
