Dry air has settled into the region behind a cold front which moved through Sunday, only bringing measurable rain to areas south of I-70. Most of Mid-Missouri hasn't had rain since early August and moderate drought has set in along and north of I-70.
Forecast models indicate that the ridge of high pressure aloft which is centered over the Rockies will gradually expand back to the east, shifting the main storm track farther north, resulting in dry weather in Missouri for the rest of the week and into early next week. Temperatures will slowly warm, reaching the low 90s by September 9th.
We have only had 6.38 inches of rain (as of Sept2) since June 1st in Columbia which is 7.23 inches below average. This is almost as dry as summer 2012 when we had only 5.96 inches of rain since June 1st but it was much hotter.
