Showers and thunderstorms will be isolated in the west and scattered over the east today, as drier air begins to work into western zones. For locations east of Billings, there is a 20-50% chance of additional wetting rain (highest near the Dakotas), and some showers may produce heavy rain. Warmer and drier conditions expected Sunday and Monday, with western zones likely to see afternoon RHs in the teens to low 20s. Tuesday is looking warm and dry as well, but a late day cold front is expected to bring a shift to breezy north winds followed by cooler conditions through midweek.
