| Message 1’s have been issued for the entire District and will be valid until 1:00 AM Saturday. A boundary has moved in from the N/NE and has sparked late evening thunderstorms which may become more numerous over the next few hours. Relatively fast storm motions will help to reduce point rainfall amounts from a single storm with training of thunderstorm cells possibly producing periods of heavy rainfall that may result in excessive runoff. Thunderstorms will generally move from WNW to ESE at 20-25mph with stronger storms potentially moving more slowly. Strong thunderstorms may also contain hail, gusty winds as well as brief heavy rainfall. Best chances for storms will be over the next 2-3 hours, most likely favoring areas along and E of I-25. |
WORST CASE SCENARIO: Training of thunderstorm cells may produce heavy rainfall of up to 2.0” in 60-75 minutes.
