POPS GOING ACROSS THE WESTERN 2/3 OF THE AREA TONIGHT WITH A LULL

SYNOPTIC SCALE FORCING WILL BE MAXIMIZED OVER THE LOCAL FORECAST
AREA WEDNESDAY NIGHT AHEAD OF THE UPPER TROUGH AXIS MOVING INTO
COLORADO...BRINGING ANOTHER GOOD CHANCE OF RAIN AND
THUNDERSTORMS. BEST INSTABILITY WILL BE ALONG AND NORTH OF THE
ASSOCIATED SURFACE COLD FRONT...WHICH AT 00Z WILL BE IN THE
NORTHWEST PORTION OF THE AREA AND BY 12Z JUST EXITING THE AREA.
INSTABILITY AND DEEP LAYER SHEAR PARAMETERS ARE MODEST AT
BEST...CANNOT RULE OUT A FEW SEVERE STORMS BUT THE OVERALL THREAT
LOOKS RATHER MUTED. ADDITIONAL 12-HOUR QPF WEDNESDAY NIGHT WILL BE
HIGHEST NORTH OF INTERSTATE 70 WHERE MODELS SHOW GENERALLY 0.25 TO
0.50 INCHES...SOME LOCAL AMOUNTS COULD EXCEED ONE INCH. THOSE
NUMBERS WOULD NOT GENERALLY WARRANT A FLOOD WATCH...BUT WITH
SEVERAL DAYS OF RAIN/SATURATED GROUND CONDITIONS ONE MAY HAVE TO
BE CONSIDERED AT A LATER TIME.

MAIN TROUGH AXIS WILL SWING THROUGH DURING THE DAY ON THURSDAY
WITH THUNDERSTORM CHANCES CONTINUING...MAINLY IN THE AFTERNOON
WITH PEAK HEATING. BEST INSTABILITY WILL BE IN THE FAR SOUTHEAST
COUNTIES JUST ON THE COOL SIDE OF THE SURFACE FRONT WHERE DEEP
LAYER SHEAR WILL BE UP TO 40KTS. ALTHOUGH BETTER SEVERE CHANCES
WILL LIKELY BE JUST SOUTH OF THE AREA NEAR THE FRONT...COULD SEE
A FEW SEVERE STORMS IN THE HILL CITY TO GOVE AREAS...WITH LESSER
CHANCES NORTH AND WEST AS INSTABILITY RAPIDLY DIMINISHES. UPPER
SYSTEM CONTINUES TO MOVE EAST THURSDAY NIGHT AND THUNDERSTORMS
WILL END WEST TO EAST. TEMPERATURES WILL BE BELOW NORMAL.

ISOLATED SHOWERS/THUNDERSTORMS MAY LINGER INTO FRIDAY MORNING IN
THE FAR EAST COUNTIES...NORTON AND GRAHAM...BUT OTHERWISE THE
SYSTEM WILL BE PULLING AWAY WITH CLEARING SKIES FOR FRIDAY
AFTERNOON. TEMPERATURES WILL BE SLIGHTLY BELOW NORMAL.

SHORTWAVE RIDGING OVER THE WEEKEND WILL RESULT IN DRY CONDITIONS
AND WARMING TEMPERATURES...WITH HIGHS BACK TO NEAR 90 BY SUNDAY.

LONGWAVE TROUGH WILL DIG INTO THE NORTHERN ROCKIES EARLY NEXT
WEEK. DISTURBANCES ROTATING AROUND THE TROUGH WILL BRING A CHANCE
FOR SHOWERS AND THUNDERSTORMS MONDAY NIGHT AND AGAIN ON TUESDAY.
TEMPERATURES WILL BE NEAR NORMAL ON MONDAY AND SLIGHTLY BELOW
NORMAL ON TUESDAY.
