IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...UPPER LEVEL LOW PRESSURE SOUTH OF THE 4 CORNERS CONTINUES
TO SPIN MOISTURE NORTHWARD ACROSS THE SITE...WHILE A BROAD AREA OF LOW
PRESSURE OVER OKLAHOMA AND TEXAS CONTINUES TO KEEP LOW LEVEL UPSLOPE
FLOW IN PLACE.  THE TWO SYSTEMS WILL WORK TOGETHER TODAY TO KEEP
SCATTERED AFTERNOON AND EVENING THUNDERSTORMS IN THE FORECAST FOR THE
SITE...ALONG WITH COOLER THAN NORMAL TEMPERATURES.

ALTHOUGH IT IS HARD TO TELL FOR CERTAIN...SATELLITE IMAGERY SEEMS TO
BE SHOWING A LOW CLOUD DECK BANKED UP AGAINST THE SLOPES OF GREENHORN
MOUNTAIN.  AT THE PRESENT TIME...IT LOOKS LIKE IT EXTENDS OUT TO ABOUT
COLORADO CITY.  ABOVE THE LOW CLOUDS ARE SCATTERED MID AND HIGHER LEVEL
CLOUDS...TRACKING FROM EAST TO WEST.  WOULD EXPECT THIS CLOUD DECK TO
PERSIST INTO THE MORNING HOURS...WITH DISSIPATION EITHER BY LATE MORNING
OR EARLY AFTERNOON.  NOT SURE OF THE BASES OR TOPS ON THE LOW CLOUD DECK.
THE LA VETA PASS SENSOR...SOUTH TO SOUTHWEST OF THE SITE...IS INDICATING
A CEILING AT 200 FEET OVERCAST CURRENTLY.  A FEW SENSORS AROUND THE REGION
ARE INDICATING THE MID LEVEL CLOUDS MAY BE IN THE 6000-8000 FOOT RANGE.

THUNDERSTORMS OVER THE SITE WILL PROBABLY START UP CLOSE TO NOON. PRIMARY
THREATS FROM ANY STORMS THAT CROSS THE AREA WILL INCLUDE LIGHTNING...HEAVY
RAIN...PEA SIZE HAIL AND WIND GUSTS TO 40 MPH.
