.SHORT TERM...
(TONIGHT AND FRIDAY)

...MAIN SHORT TERM CONCERN REMAIN SEVERE THUNDERSTORM POTENTIAL
ACROSS THE PLAINS THROUGH THIS EVENING...

CURRENT WATER VAPOR IMAGERY AND RUC UPPER AIR ANALYSIS INDICATING
GENERALLY WEAK WESTERLY FLOW ALOFT ACROSS THE STATE AS UPPER LEVEL
RIDGING ACROSS THE SOUTHERN HIGH PLAINS THROUGH THE DESERT SW IS
EXPANDING INTO THE SOUTHERN GREAT BASIN REGION ATTM. WATER VAPOR
IMAGERY ALSO INDICATING VERY DRY AIR EMBEDDED WITHIN THE FLOW
ALOFT...SAVE ALONG WITH COLORADO AND NEW MEXICO BORDER...WITH
MONSOONAL MOISTURE PLUME SHUNTED TO THE SOUTH AND EAST OF THE
STATE. LOW LEVEL MOISTURE...HOWEVER IS IN PLACE ACROSS THE EASTERN
PLAINS WITH CURRENT DEW PTS IN THE MID 50S TO MID 80S...WITH DEW PTS
IN THE MID 20S TO MID 40S ACROSS THE HIGHER TERRAIN AND HIGH VALLEYS
ATTM. REGIONAL SATELLITE AND RADARS INDICATING CU BUILDING ACROSS
THE HIGHER TERRAIN WITH A FEW ECHOES ACROSS THE SOUTHEASTERN MTS
ATTM.

THIS AFTERNOON AND TONIGHT...CURRENT AND PROGGED CAPES ACROSS THE
EASTERN PLAINS ARE BETWEEN 1500-3000 J/KG. LOW LEVEL UPSLOPE
INCREASES ACROSS THE PLAINS THROUGH THE LATE AFTERNOON WITH LOWERING
PRESSURES ACROSS THE HIGH TERRAIN...AND COMBINED WITH 20-25KT
WESTERLY FLOW ALOFT...WILL ALLOW FOR POTENTIAL OF A FEW SUPER CELLS
WITH BULK SHEARS BETWEEN 30-40KTS THROUGH THE LATE EVENING.
HOWEVER...THE DRIER WESTERLY FLOW ALOFT IS HELPING TO MIX OUT LOW
LEVEL MOISTURE ACROSS THE EASTERN MTS (LXV AND LAKE GEORGE RAWS DEW
PTS MIXED FROM MID 40S AND MID 50S TO THE LOWER 20S AND MID 30S FROM
16Z TO 18Z) AND WITH NO EVIDENT SHORT WAVE TO HELP INITIATE
CONVECTION...WILL NEED RELAY ON SOLAR HEATING. CONVECTIVE TEMPS
ACROSS THE PLAINS ARE IN THE UPPER 80S TO MID 90S WHICH WITH THE
MORNING CLOUDS AND INCREASING LOW LEVEL UPSLOPE MAY NOT BE
MET...ESPECIALLY ACROSS THE FAR SE PLAINS. WITH THAT SAID AND
CONVECTION ALREADY UNDERWAY ACROSS THE SOUTHEASTERN MTS...SHOULD SEE
ISOLATED TO SCATTERED THUNDERSTORMS CONTINUING TO DEVELOP ACROSS THE
EASTERN MTS...WITH STORMS MOVING OFF THE HIGHER TERRAIN HELPING TO
FIRE A FEW SEVERE THUNDERSTORMS ACROSS THE IMMEDIATE ADJACENT PLAINS
THROUGH THE EARLY EVENING. MAIN THREATS FROM THE SEVERE STORMS WILL
BE LARGE HAIL UP TO 1.5 INCHES IN DIAMETER ALONG WITH LOCALLY HEAVY
RAINFALL AND GUSTY WINDS UP TO 50 MPH POSSIBLE WITH ALL STORMS
THROUGH THE EVENING. ANY CONVECTION SHOULD DIMINISH WITH THE SUN AND
WITH DRY WESTERLY FLOW ALOFT...SHOULD CLEARING FROM SEE WEST TO EAST
THROUGH THE OVERNIGHT.

FRIDAY...UPPER LEVEL RIDGING ACROSS THE DESERT SW AND SOUTHERN GREAT
BASIN CONTINUES TO BUILD INTO WESTERN COLORADO ALLOWING FOR
CONTINUED WARMING AND DRYING ALOFT WITH H7 TEMPS PROGGED BETWEEN 16C
AND 20C...WARMEST ACROSS THE WESTERN HALF OF THE AREA. WITH THE
WARMING ALOFT AND STRONG MID JULY SUNSHINE SHOULD SEE HIGHS WARMING
BACK INTO THE 90S AND LOWER 100S ACROSS THE PLAINS WITH LOW LEVEL
MOISTURE PROGGED TO MIX OUT ACROSS THE NORTHERN HALF OF THE AREA
THROUGH THE LATE MORNING. THERE HOWEVER LOOKS TO BE ENOUGH MOISTURE
REMAINING ACROSS SOUTHEASTERN MTS AND FAR SE PLAINS...COMBINED WITH
SOLAR HEATING...WITH PRODUCE ISOLATED TO SCATTERED AFTERNOON
THUNDERSTORMS MOST NUMEROUS ACROSS THE SE MTS WITH A FEW STRONGER
STORMS POSSIBLE WITH CAPES VALUES PROGGED BETWEEN 800-1200 J/KG.
ANY CONVECTION ELSEWHERE WILL BE HIGHER BASED...WITH MORE WIND THAN
RAINFALL EXPECTED. -MW

.LONG TERM...
(FRIDAY NIGHT THROUGH THURSDAY)

THE UPR RIDGE WL BE CENTERED OVR NERN AZ THRU SUN...THEN SHIFTING
EASTWARD MON AND TUE...BECOMING CENTERED OVR THE CENTRAL PLAINS STATES
TUE. SO FOR SAT AND SUN THE FLOW ALOFT OVR THE CWA WL BE NWRLY
WITH A FEW SHRTWV TROFS MOVING OVR THE RIDGE AND BRUSHING BY NERN
CO AND RE-ENFORCING THE LOW LEVEL UPSLOPE FLOW OVR THE SERN
PLAINS. THERE WL LIKELY BE ENOUGH MSTR OVR THE AREA SAT AND SUN TO
SEE SOME ISOLD PCPN DEVELOP...ESPECIALLY OVR AND NR THE MTS. WITH
THE RIDGE SHIFTING EASTWARD NEXT WEEK AND A TROF MOVES INTO THE
PAC NW...THE FLOW ALOFT OVR THE AREA WL BECOME SWRLY. BEGINNING
LATE MON IT LOOKS LIKE A PLUME OF MSTR WL BE STREAMING ACRS THE
FORECAST AREA THROUGH THU. THE AVAILABLE MSTR IN ADDITION TO
DAYTIME HEATING AND OCNL SHRTWV TROFS MOVING THRU THE FLOW OVR THE
AREA...SHOULD LEAD TO THE POTENTIAL FOR DAILY CHANCES FOR SHOWERS
AND STORMS...WITH THE BEST CHANCES BEING OVR AND NR THE HYR TRRN.
ABOVE NORMAL TEMPERATURES WILL CONTINUE EACH DAY. HIGHS OVR THE
SERN PLAINS WL RANGE FROM THE MID 90S TO AROUND 104.

PRODUCING HAZARDOUS LIGHTNING...GUSTY WINDS...LOCALLY HEAVY
RAINFALL AND LOCALIZED HAIL AROUND 1 INCH IN DIAMETER WITH THE
STRONGER STORMS WILL BE POSSIBLE FROM FRIDAY INTO NEXT MONDAY.

INCREASED ATMOSPHERIC MOISTURE MEANS THAT ISOLATED TO SCATTERED
THUNDERSTORMS SHOULD BE NOTED(ESPECIALLY MOUNTAIN AND WESTERN
SECTIONS) FROM LATER MONDAY INTO NEXT WEDNESDAY. THE PRIMARY
THREATS WITH THESE STORMS FROM LATER MONDAY INTO NEXT WEDNESDAY WILL
ONCE AGAIN BE HAZARDOUS LIGHTNING...GUSTY WINDS...LOCALLY HEAVY
