.SHORT TERM...
(TONIGHT AND SUNDAY)

...POTENTIAL FOR RELATIVELY RARE NOCTURNAL CONVECTIVE EVENT
TONIGHT...

CURRENTLY...LOW LEVEL MOISTURE ON THE PLAINS HAS DECREASED
SIGNIFICANTLY MOST AREAS...THOUGH WITH WEAK PRESSURE FALLS ALONG
THE I-25 CORRIDOR BEGINNING TO SHOW UP AT 20Z...SUSPECT DEWPOINTS
HAVE BOTTOMED OUT AND WILL BE ON THE INCREASE THE REST OF THE DAY.
STRONG UPPER TROUGH OVER THE GREAT BASIN HAS BEEN SLIGHTLY TOO FAR
WEST TO HELP MUCH WITH TSRA SO FAR THIS AFTERNOON...THOUGH A FEW
TCU HAVE FINALLY FORMED OVER THE CENTRAL MTS AND ERN SLOPES OF THE
SANGRES.

TONIGHT...ETA AND RUC SUGGEST ELY FLOW WILL INCREASE THROUGH MUCH OF
THE NIGHT...WITH AIR MASS OVER THE ERN MTS AND PLAINS BECOMING
FAIRLY UNSTABLE BY 06Z WITH CAPES NR 1000 J/KG ALONG AND EAST OF
I-25. NICE BULLSEYE OF UPWARD MOTION OVER MUCH OF THE PLAINS BY 06Z
AS SIGNIFICANT SYNOPTIC LIFT ASSOCIATED WITH WRN U.S. UPPER TROUGH
OVERSPREADS THE AREA. SUSPECT -TSRA WILL LAST THROUGH MOST OF THE
NIGHT...SIMILAR TO WHAT HAPPENED LAST NIGHT OVER THE GREAT BASIN.
MIGHT EVEN BE SOME MARGINAL SEVERE HAIL OVER THE PLAINS IF MODEL
CAPES ARE IN THE BALL PARK. ALSO SOME POTENTIAL FOR LOCAL HEAVY
RAIN GIVEN STRENGTH OF THE PROGGED UPWARD VERTICAL MOTION. CURRENT
GRIDS HAVE THINGS IN HAND AND NEED FEW CHANGES.

SUNDAY...UPPER TROUGH LIFTS INTO THE HIGH PLAINS BY AFTERNOON...
WITH PRONOUNCED MID LEVEL THERMAL TROUGH OVER COLORADO DURING THE
DAY. AMOUNT OF INSTABILITY ON THE PLAINS WILL DEPEND ON WHERE THE
NOCTURNAL MCS ENDS UP...BUT THERE SHOULD BE ENOUGH MOISTURE LEFT FOR
ONE MORE ROUND OF CONVECTION OVER THE AREA. STILL SOME SEVERE
POTENTIAL FOR ERN ZONES...WHERE ETA SHOWS DRYLINE SETTING UP NEAR
THE CO/KS BORDER BY AFTERNOON. SHADED SUN MAX TEMPS TOWARD THE
COOLER MAV GUIDANCE...WITH REMAINING GRIDS LOOKING A-OK.  --ETP

.LONG TERM...
(SUNDAY NIGHT THROUGH SATURDAY)

SUN NIGHT-MON...MODERATE WEST TO NORTHWEST FLOW ALOFT ACROSS THE
REGION SUN NIGHT SLOWLY WEAKENS THROUGH THE DAY MONDAY...AS BROAD
UPPER LOW AND ASSOCIATED 90KT JET MOVES ACROSS THE NORTHERN ROCKIES
AND INTO THE NORTHERN HIGH PLAINS. BRISK WESTERLY FLOW PUSHES
DRYLINE OUT ACROSS THE KANSAS BORDER SUN EVENING AND INTO WESTERN
KANSAS OVERNIGHT...WITH WEAK NORTHERLY SURGE ACROSS THE PLAINS
AS SYSTEM LIFTS INTO THE NORTHERN HIGH PLAINS. WILL KEEP CURRENT
CHANCE AND SLIGHT CHANCES POPS IN PLACE THROUGH THE EVENING...WITH
BEST COVERAGE ACROSS THE FAR SE PLAINS. WITH SOME MOISTURE WRAPPING
AROUND SYSTEM AND GOOD OROGRAPHIC FLOWS...WILL KEEP CURRENT ISOLATED
POPS OVERNIGHT ACROSS THE CENTRAL MTS AS WELL. WITH SUBSIDENCE
BEHIND PASSING SYSTEM ALONG WITH BUILDING UPPER RIDGE ACROSS THE
GREAT BASIN...WILL SEE DRY CONDITIONS AREA WIDE ON MON...THOUGH WILL
SEE BREEZY WEST TO NORTHWEST WINDS MIX DOWN ACROSS THE REGION IN THE
AFTERNOON.

TUE-THU...UPPER LEVEL RIDGE ACROSS THE GREAT BASIN CONTINUES TO
BUILD ACROSS THE STATE...AS EASTERN PACIFIC SYSTEM SLOWLY MOVES
ONSHORE ACROSS THE PAC NW COAST. WARM AIR ALOFT ASSOCIATED WITH
BUILDING RIDGE (+10C TO +16C AT H7) WILL ALLOW FOR AT OR ABOVE
SEASONAL TEMPERATURES THROUGH THE PERIOD...SAVE TUESDAY ACROSS THE
EASTERN PLAINS...AS SECONDARY BACKDOOR COOL FRONT MOVES ACROSS THE
CENTRAL HIGH PLAINS. MODELS INDICATING VARIOUS AMOUNTS OF MOISTURE
EMBEDDED IN THE FLOW...AND WITH DAYTIME HEATING...CANT RULE OUT THE
POSSIBILITY OF ISOLATED AFTERNOON AND EVENING SHRA/TSRA ACROSS THE
THE REGION THROUGH THE PERIOD.

FRI-SAT...WARM SW FLOW REMAINS ACROSS THE REGION AS PAC NW SYSTEM
RIDES THE PERIPHERY OF UPPER RIDGE ACROSS THE ROCKIES. MODELS KEEPING
SFC HIGH PRESSURE ACROSS THE MIDWEST WITH VARYING DEGREES OF MOISTURE
IN WEAK EASTERLY UPSLOPE IN PLACE ACROSS THE EASTERN PLAINS...THOUGH
WILL KEEP CURRENT WARM AND DRY FORECAST IN TACT ATTM.  -MW
