| Message 1’s have been issued for the entire District effective until 6pm. Storms have initiated early this morning, with another stronger round expected this late this morning and into the afternoon hours. Storms this morning could possibly produce some brief moderate to heavy rain with the largest threat being a quick 0.5” in 10-15 minutes. Typical storm movements will be from W/NW to E/SE between 10-20mph which should help limit point rainfall amounts. However, with low to mid 50 dew points, a stalled out storm formed along an outflow boundary will have the potential to produce localized heavy rainfall. The best chance for storm activity will be from now through the late afternoon with storms likely decreasing into the evening with skies clearing this evening. A chance for isolated heavy rain this morning, with a better chance for widespread storms along the I-25 corridor during the afternoon. Some of these storms could become severe with large hail up to 1.5”, gusty winds 60+mph, frequent cloud-to-ground lightning. A weak land spout/tornado cannot be completely ruled out, favoring areas east of I-25. |
WORST CASE SCENARIO: A stationary strong thunderstorm, or training of thunderstorm cells has the potential to produce 2.50” in 45-60 minutes.
