SHORT TERM...
(TODAY AND TONIGHT)

..SEVERE STORMS POSSIBLE THIS AFTERNOON...

CURRENTLY...STILL SOME ISOLD TS OVER THE LOWER ARKANSAS VALLEY...AS
A SERIES OF WEAK DISTURBANCES MOVE THROUGH THE NW FLOW. STORMS HAVE
BEEN MOVING QUICKLY...UP TO 35 MPH...SO HYDRO ISSUES HAVE NOT BEEN
TOO STRESSFUL OVERNIGHT. WILL KEEP ISOLD POPS GOING THRU THIS
MORNING...BUT TAPER HIGHEST POPS TO THE ERN ZONES. THE LATEST NAM
STILL INSISTS ON GENERATING A SEMBLANCE OF MCS OVER NERN CO THIS
MORNING...REINFORCING A FRONTAL PUSH OVR THE PLAINS BY MID MORNING.
TEMPS SHOULD BE 5 TO 10 DEGREES LOWER TODAY OVR THE PLAINS.

MAIN QUESTION TODAY IS POTENTIAL FOR SVR WX LATER THIS AFTERNOON.
SPC DY1 HAS MOST OF SERN CO OUTLOOKED FOR SLIGHT RISK. SFC DEWPTS
REMAIN QUITE HIGH...CURRENTLY IN THE 50S AND EVEN SOME LOWER 60S.
ALTHOUGH THERES NO PARTICULARLY STRONG SHORTWAVE MOVING THRU
TODAY...AREA WILL REMAIN UNDER CYCLONIC NW FLOW ALOFT...AND WITH
SOME INSOLATION AND UPSLOPE WINDS...WONT TAKE MUCH TO KICK OFF
CONVECTION WITH MODEST CAPPING. NAM PROGS A SOMEWHAT NARROW AXIS OF
HIGHER CAPE...1500-2000 J/KG...MOVING S AND WWD WITH THE FRONTAL
PUSH THIS AFTERNOON. COMBINED WITH DEEP LAYER SHEAR OF 50+
KTS...THERE IS THE POTENTIAL FOR SUPERCELL DEVELOPMENT. MAIN
QUESTION IS HOW THE FRONTAL PUSH AND ALL THE RECENT CONVECTION WILL
AFFECT LLVL INSTABILITY. MAY BE A BIT TOO STABLE OVR PORTIONS OF THE
PLAINS FOR SVR TO DEVELOP. BEST CHANCE WILL BE LATE THIS AFTERNOON S
OF HIGHWAY 50 AND ALONG AND E OF I-25...WITH HIGHEST RISK OVR THE
RATON MESA. HOWEVER...WITH ABUNDANT MOISTURE AND STRONG MID-LEVEL
WINDS COVERING THE ERN PART OF CO...REALLY CAN NOT UNDERESTIMATE THE
SVR POTENTIAL...SO WILL HAVE MENTION OF SVR FOR ALL THE PLAINS THIS
AFTERNOON AND EVE. MAIN THREAT WILL BE LARGE HAIL UP TO 2
INCHES...AND WIND GUSTS IN EXCESS OF 60 MPH. GENERALLY MODEST LLVL
WINDS WILL LIMIT THE TORNADO THREAT...BUT WITH SUCH STRONG MID LEVEL
ROTATION POSSIBLE...CAN NOT RULE OUT AN ISOLD TORNADO EITHER.

SHOULD SEE THE HEAVY CONVECTIVE ACTIVITY SHIFT TO THE S AND E IN
THE EVENING...AND SOME CLEARING POSSIBLE OVERNIGHT FROM N TO S.
WILL CONTINUE LOW/ISOLD POPS THRU THE MORNING HOURS. WITH ALL THE
LLVL MOISTURE...COULD ONCE AGAIN SEE SOME PATCHY LOW CLOUDS OR FOG
DEVELOP BY EARLY MORNING. 44

LONG TERM...

..ACTIVE THROUGH THURSDAY...THEN DRIER AND WARMER INTO THE WEEKEND...

ON WEDNESDAY...A MAJOR SHORTWAVE TROUGH IS PROGGED TO DROP SOUTH
ALONG THE NORTHERN ROCKIES...SENDING A SURFACE HIGH SOUTH THROUGH
THE HIGH PLAINS. THIS WILL RESULT IN A COOL AND UNSETTLED PERIOD
WEDNESDAY THROUGH THURSDAY...WITH THE POTENTIAL FOR SEVERE WEATHER
AND HEAVY RAIN. MORE FLOODING WILL ALSO BE A CONCERN ESPECIALLY
GIVEN THE AMOUNT OF RAINFALL WEVE HAD LATELY.

IT LOOKS LIKE THINGS WILL HEAT UP AND DRY OUT AGAIN FRIDAY...SATURDAY
AND INTO SUNDAY AS WEAK RIDGING BUILDS IN ACROSS THE STATE...RESULTING
IN A LEE TROUGH ACROSS THE PLAINS...WITH DOWNSLOPE INTO THAT
TROUGH. TEMPERATURES SHOULD REBOUND TO NEAR SEASONAL LEVELS AND
THUNDERSTORM COVERAGE SHOULD DECREASE TO ISOLATED AT BEST.

ANOTHER ROUND OF COOL...MOIST WEATHER MAY MOVE INTO THE AREA SUNDAY
AFTERNOON AND PERSIST THROUGH AT LEAST MONDAY. MUCH LIKE FRIDAY
AND SATURDAY...A FAIRLY MAJOR SHORTWAVE DROPS SOUTH ALONG THE
ROCKIES SUNDAY AFTERNOON...SENDING ANOTHER SURGE OF SURFACE HIGH
PRESSURE SOUTH THROUGH THE HIGH PLAINS. THIS WOULD REVERSE THE
FLOW OVER THE PLAINS TO UPSLOPE...RESULTING IN INCREASED MOISTURE
AND MORE WIDESPREAD THUNDERSTORM ACTIVITY. THERE ARE...OF
COURSE...SOME TIMING DIFFERENCES BETWEEN THE PRIMARY MEDIUM RANGE
MODELS SO CONFIDENCE IN WHEN THIS CHANGE WILL TAKE PLACE IS A
LITTLE LOW RIGHT NOW. LW

AVIATION...LOW CLOUDS A BIT SLOW TO DEVELOP THIS MORNING...SO
WILL BE CONSERVATIVE WITH CIGS IN THE TAFS THIS MORNING...ALTHOUGH
THERE IS STILL THE POTENTIAL THRU THE MORNING HOURS FOR LOW
CLOUDS/STRATUS TO MOVE IN FROM THE NE. WILL SEE CONVECTION DEVELOP
RATHER EARLY TODAY...WITH THE POTENTIAL FOR TS AT KCOS BY LATE
MORNING...SPREADING SWD TO KPUB BY 18-20Z. STORMS COULD BE ON THE
STRONG SIDE...ESPECIALLY S OF HWY 50 AND E OF I-25...WITH THE
POTENTIAL FOR STRONG SFC WINDS AND LARGE HAIL. SOME LCL MVFR TO
POSSIBLY IFR CONDITIONS WILL BE POSSIBLE BY WED MORN FOR THOSE AREAS
RECEIVING HEAVY RAINFALL. 44
