| An upper-level disturbance has moved into northern Colorado this evening creating a line of storms just north of the District. These storms will move SE between 10-15mph with additional storms possible off outflow boundaries into the later evening. Storm motions should help limit point rainfall amounts. However, erratic movement could produce longer lasting localized heavy rainfall. The largest threat of heavy rain will be a quick 0.5” in 10-20 minutes. Storms may also contain large hail up to 1.0” and gusty winds up to 60mph. Currently storms will favor north and northeastern portions of the District, with other storms potentially forming across other portions of the District as the night continues. Storms will start to dissipate by midnight, with the threat for heavy rainfall likely following suit. |
WORST CASE SCENARIO: Strong stationary, or training of thunderstorms has the potential to produce 0.50” to 1.00" total in under 30 minutes.
