This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...This afternoon and tonight

Isolated to scattered afternoon and early evening thunderstorms will
develop over the mountains. These storms will be capable of
producing locally heavy downpours, which could cause flash flooding
on the recent burn scars. The storms could also produce gusty winds
and cloud to ground lightning.

Later in the afternoon and into the evening, isolated to scattered
thunderstorms will develop over the Interstate 25 corridor and the
eastern plains. Low level moisture will be more abundant east of the
Interstate 25 corridor, where a few storms could be strong to
severe. The best chances for severe storms will be in Crowley,
Otero, Kiowa, Bent and Prowers Counties. The main threats from these
severe storms will be hail around 1 inch in diameter and wind gusts
to 70 mph.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Monsoonal moisture is expected to increase across the area into
early next week, leading to increasing coverage and intensity of
daily afternoon and evening showers and thunderstorms across South
Central and Southeast Colorado. Scattered to numerous showers and
storms can be expected across the area Sunday and Monday, with
isolated to scattered storms expected on Saturday, and again
Tuesday through Thursday. The main threats from thunderstorms will
be lightning, locally heavy rain and gusty outflow winds of up to
40 mph. Small hail will also be possible with a few of the
strongest storms. With the increasing moisture and potential for
heavy rainfall, flash flooding concerns will also be on the
increase across the area, especially if locally heavy downpours
occur over a recent burn scar.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible from this afternoon into this evening over the recent burn
scars as well as portions of the eastern plains.
