| - | NW flow aloft continues today with temperatures warming into the lower 90's over the plains with 70's and 80's in the Front Range foothills. |
| - | Conditions will be dry through early afternoon with thunderstorm chances increasing by 3-4pm. A round of generally weak to moderate thunderstorms is then expected to move through into the evening with possibly a lingering rain shower into the early overnight period. Storms that develop today will be relatively fast moving from NW to SE at 25-30mph. |
| - | Stronger thunderstorms may produce moderate to brief heavy rain and possibly hail along with gusty straight-line winds. |
WORST CASE SCENARIO: A large slower moving thunderstorm may produce rainfall rates of 0.3-0.8" in 10-30 minutes.
A LOOK AHEAD: Temperatures will back off into the 80's for highs on Sunday as a cool front moves through. Thunderstorm activity is expected to increase and stronger storms will be capable of producing heavy rainfall.
