NATIONAL WEATHER SERVICE DENVER CO
300 PM MDT SUN JUN 10 2007

.SHORT TERM...SFC TEMPS APPROACHING 90 DEGREES ON THE PLAINS THIS
AFTN WHILE LOW LVL MSTR IS MIXING OUT WITH VRY DRY LOW LVLS.
DEWPOINTS ARE DOWN INTO THE MID 20S OVER THE URBAN CORRIDOR BUT
STILL SOME MID 40S ACROSS FAR ERN CO. THERE IS A SFC BOUNDARY
DRAPPED ACROSS THE EASTERN PLAINS...FROM AROUND LIC AND STRETCHING
NORTHEAST TO JULESBURG AS SOME SHOWERS HAVE DEVELOPED ALONG THIS
BOUNDARY. SFC BASED CAPES AHD OF THE MSTR ARE IN THE 1000-1500J/KG
RANGE BUT WITH WEAK WINDS ALOFT SEVERE STORMS ARE NOT EXPECTED. SO
NO REASON CONVECTION WILL LAST BEYOND EVENING SO WILL END
PRECIP/LOWER CLDS OVERNIGHT BEHIND WEAK WAVE EXITING NERN CO.

FOR MONDAY...INCREASING SERLY LOW LVL FLOW WILL ENABLE DEWPOINTS TO
INCREASE OVER THE NERN PLAINS. MID LVL MSTR WILL ALSO BE ON THE
INCREASE ALSO AS SAT PICS SHOWING A MSTR SWATH INCREASING ACROSS THE
DESERT SOUTHWEST AHD OF WAVE OFF BAJA. DIRECTIONAL AND SPEED SHEAR
WILL INCREASE OVER THE FAR PLAINS...SO THERE MAY BE A FEW SEVERE
STORMS THERE LATER IN THE AFTN AND INTO MON EVENING. FURTHER WEST
OVER THE URBAN CORRIDOR...SHEAR IS WEAKER AND MORE UNIDIRECTIONAL SO
SEVERE THREAT WOULD BE LOWER FURTHER WEST. SFC TEMPS FOR MON AFTN
WILL BE EVEN WARMER STILL WITH READINGS WELL INTO THE LOWER 90S.

.LONG TERM...UPR TROF XPCTD TO TRAVERSE THE MTNS MONDAY NGT WITH SFC
FNT LAGGING A FEW HRS BEHIND.  ONE DISTURBANCE LOOKS TO CLIP THE
NERN CORNER OF THE DISTRICT MONDAY NIGHT.  WK LIFT DEPICTED IN THE
MDLS OVERNIGHT MONDAY INTO TUES WHICH COULD KEEP CONVECTION GOING
PAST MIDNIGHT ON THE PLAINS.  WL ADD SOME SCT POPS TO THE ENTIRE
CWFA MONDAY NIGHT INTO TUES MRNG.  AS SFC SURGE MOVES SWD INTO THE
PLAINS LATER TUES MRNG...COOLER BATCH OF AIR WL BE IN PLACE DURING
THE AFTN.  TEMPS WL BE CONSIDERABLY COOLER AS A RESULT WITH MAX
TEMPS ARND 15 DEGREES LOWER THAN THE PAST COUPLE OF DAYS.  AIRMASS
WL BE QUITE MOIST ALF...BUT NOT OVERLY IMPRESSED WITH AMT OF MSTR
CLOSER TO THE SFC TUES AND WL KEEP SCT POPS IN PLACE FOR TUES AND
TUES NGT.

NAM 12 DEPICTS SOME UPSLOPE TUESDAY NIGHT BEFORE LOW LVL FLOW TURNS
SELY WEDNESDAY.  RETURN FLOW TO THE SOUTHEAST MAY LEAD TO MORE MSTR
RETURNING TO THE LOW LVLS IN A DAY-2 SCENARIO.  NOT TOO INCLINED TO
BITE ON THIS AS THESE SELDOM PAN OUT AS PROGGED.  WL ADD SOME ISOLD
POPS ON THE PLAINS FOR NOW.  TEMPS WL BE COOL ONE MORE DAY WITH MAX
TEMPS IN THE 70S FOR THE MOST PART.

FOR THURS AND BEYOND...STG RDG OF HIGH PRESSURE WL DVLP ACRS THE
WEST SLOPE AND GREAT BASIN.  TEMPS ALF SUPPORT SOME WELL ABV NRML
TEMPS.  MDLS INDG SOME NWLY FLOW AS RDG SITS OFF TO OUR WEST...BUT
GIVEN THIS LONG WAVE PTRN...WL GO SVRL DEGREES ABV GDNC IN UPCOMING
WEATHER FORECAST.  TYPICAL LATE JUNE AFTN/EVENING TSTMS EACH DAY.
