CHALLENGE TODAY...COVERAGE/STRENGTH OF STORMS AND HEAVY RAIN POTENTIAL.
SATELLITE SHOWS DEEP MOISTURE AND MID LEVEL CLOUDS OVER SAN LUIS VALLEY
WITH SCATTERED SHOWERS AND TSTORMS ON DOPPLER.  ALSO A BOUNDARY OVER
EASTERN KIOWA AND NORTHWEST PROWERS COUNTIES HAS FIRED SLOW MOVING
STORMS IN EASTERN KIOWA COUNTY BRINGING VERY HEAVY RAIN NEAR SHERIDAN
LAKE. STORMS WERE ALSO FORMING OVER ALL THE SOUTHERN MTNS.

MODELS AGAIN IN GENERAL AGREEMENT IN 1ST PERIOD...INDICATING VERY DEEP
MONSOON MOISTURE WILL REMAIN IN WESTERN COLORADO.  AS SURFACE HIGH
DIVES SOUTH IN NORTHERN PLAINS...UPSLOPE FLOW INCREASES OVER OUR
AREA...AND MAXIMUM OF H7 THETA E IN WESTERN KANSAS MOVES SOUTHWEST INTO
EASTERN COLORADO BY 00Z.

PRECIPITABLE WATER VALUES ARE QUITE HIGH AS ESTIMATED BY GOES SOUNDER
DATA...AND ATMOSPHERE WILL CONTINUE TO DESTABILIZE THE REST OF THE
AFTERNOON AS SUN WARMS GROUND.  WITH SLOW MOVEMENT OF SCATTERED STORMS
(NOW A SLOW DRIFT TO THE SOUTH IN FAR EAST COLORADO) HEAVY RAIN
POTENTIAL OF A SCATTERED OR WIDELY SCATTERED NATURE IS LIKELY.  WILL
HAVE TO WATCH TSTORMS ALONG THE MOUNTAINS FOR FLASH FLOOD POTENTIAL.
OUR SOIL IS NOT AS SATURATED AS IN NORTHEAST COLORADO...SO A FLASH
FLOOD WATCH EVEN FOR EL PASO COUNTY MAY STILL NOT BE WARRANTED AT THIS
TIME.

LARGE HAIL WILL BE AN ISOLATED THREAT AT THIS TIME...AS PROGGED
SOUNDINGS SHOW JUST ENOUGH UPDRAFT STRENGTH TO DO SOME HAILSTONES
BIGGER THAN 3/4 INCH.
