.SHORT TERM...SFC HIGH WILL REMAIN TO OUR NORTHEAST
TONIGHT...KEEPING UPSLOPE GRADIENT THRU THE NIGHT...SO ANOTHER
CLOUDY AND MOIST NIGHT IN STORE.  UPR TROF WILL PROVIDE FORCING FOR
SHOWERS AND A FEW THUNDERSTORMS THIS EVENING...FORTUNATELY WITH
BRISK FLOW ALOFT STORMS ARE NOT LINGERING OVER THE BURN AREAS....BUT
WILL NEED TO WATCH SUBSEQUENT THUNDERSTORMS THIS EVENING.
PRECIPITATION WILL LINGER ON PLAINS THIS EVENING...GIVING WAY TO
AREAS OF DENSE FOG AFTER MIDNIGHT.  DENSE FOG ADVY MAY BE NEEDED BUT

SATURDAY WILL BEGIN CLOUDY ON THE PLAINS...PARTLY CLOUDY IN THE
MOUNTAINS...BUT SHOULD ACTUALLY SOME SIGHT OF THE SUN ON PLAINS
BY MIDDAY.  DEWPOINTS WILL REMAIN HIGH...SO WE SHOULD SEE SCATTERED
CONVECTION IN THE AFTERNOON.  GUIDANCE POPS APPEAR TO BE TOO LOW.
SURFACE HIGH WILL MIGRATE TO EAST OF COLORADO EARLY SATURDAY WITH
SOUTHEAST WINDS DEVELOPING ON PLAINS.  AGREE WITH SPC SLIGHT RISK
GIVEN WIND SHEAR AND AVAILABLE MOISTURE SATURDAY AFTERNOON.

.LONG TERM DISCUSSION...SUNDAY WL BE SUBSTANTIALLY WRMR ACRS THE
PLAINS AS AIRMASS MODERATES UNDER A WLY FLOW ALF.  PRES GRADS APPEAR
TO SUPPORT WLY FLOW NR THE SFC...AND MUCH OF THE MSTR NR THE SFC

MSTR WL CONTINUE TO STREAM INTO THE AREA ARND H5 AND WITH THE STEEP
LAPSE RATES BELOW THAT...AFTN TSTMS ARE PSBL ONCE AGAIN.  MOST OF
THE STORMS SHOULD BE EAST OF AN AKRON-LIMON LINE.  SOME DRY STORMS
PSBL IN THE MTNS...BUT SHUD ONLY BE ISOLD IN COVERAGE AT BEST.  WITH
DOWNSLOPING...TEMPS WL RISE INTO THE MID 80S ACRS THE FNT RANGE AND
PLAINS.

ANOTHER STG CDFNT SLATED TO ARRIVE ACRS THE PLAINS MONDAY.  THIS FNT
LOOKS JUST AS FORMIDABLE AS THE ONE WHICH BROUGHT THE COOL WX OF THE
PAST FEW DAYS.  12Z GFS DEPICTING H7 TEMPS OF ONLY ONE ABV CELCIUS
JUST NORTH OF THE BORDER MONDAY AFTN.  WITH GOOD UPSLOPE...TEMPS WL
ONLY BE IN THE 60S FOR HIGHS...AT BEST.  WL ADJUST TEMPS DWNWARD AND
INCRS POPS MODESTLY FOR NOW.  COOL AIR SHOULD LINGER THROUGH TUES
WITH PERHAPS SOME WARMING FOR WEDNESDAY.  ANOTHER SURGE MAY ARRIVE

EXTENDED PERIOD WHICH IS VERY UNCHARACTERISTIC FOR LT JUNE.
