AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
335 PM MDT SUN JUN 2 2002

BOUNDARY REMAINS ACROSS THE SOUTHEAST PLAINS...SEPERATING AIR WITH
DEWPOINTS IN THE 40S AND 50S FROM DEWPOINTS IN THE 20S.  CU FIELD
STILL PRETTY FLAT AROUND CHEYENNE. DOPPLER RADAR SHOWS A FEW SHOWERS
TRYING TO DEVELOP ALONG THE BOUNDARY IN PLATTE AND GOSHEN COUNTIES
BUT NOT DOING TOO WELL ONCE THEY PULL OFF THE BOUNDARY. ALSO LOOKS
LIKE CONVECTION BEING INHIBITED BY RIGHT EXIT REGION OF A SPEED MAX
WHICH WORKED ITS WAY IN THE FROM THE SOUTHWESTERN U.S. EARLIER THIS
MORNING.  DONT PLAN ON DOING TOO MUCH WITH THE CHANCE OF
THUNDERSTORMS OVER THE SOUTHEAST PLAINS OR SOUTHERN PANHANDLE...WITH
ONLY BETTER CHANCE OF EVENING THUNDERSTORMS ON WEST AND NORTH SIDE
OF CWA...NOTE SEVERE THUNDERSTORM WATCH ACROSS CONVERSE AND
NIOBRARA COUNTIES UNTIL 800 PM.  COLD FRONT WILL BE DROPPING ACROSS
CWA LATER TONIGHT AND MONDAY...BRINGING CLOUDS AND AN INCREASING
CHANCE OF RAIN.  MESO ETA SHOWS A SMALL POCKET OF SUB ZERO DEGREE AIR
AT 700 MB MONDAY NIGHT...WITH THICKNESS VALUES ONLY MAKING IT TO
5570-5590 METERS...SO PLAN TO KEEP MENTION OF ANY SNOW CONFINED TO
THE MOUNTAINS THOUGH LARAMIE MAY BE CLOSE. STILL SHOULD HAVE SOME
LINGERING SHOWERS EARLY ON TUESDAY UNTIL TROF AXIS MOVES AWAY.  WILL
KEEP MENTION OF SOME SHOWERS INTO THE AFTERNOON DUE TO LAPSE RATE
GETTING CRANKED OVER BY COLD AIR ALOFT AND SOME INSOLATION.
TEMPERATURES FINALLY START REBOUNDING BY MIDWEEK AS UPPER RIDGE MOVES
IN.

IN THE EXTENDED FORECAST PERIOD...
ZONAL FLOW WILL OCCUR OVER THE FORECAST AREA ON THURSDAY...AS UPPER
HIGH IS CENTERED OVER 4 CORNERS AREA.  SOUTHWEST FLOW DEVELOPS ALOFT
ON FRIDAY AS UPPER LEVEL TROUGH MOVES INTO THE PACIFIC NORTHWEST.
COOLER WITH A CHANCE OF SHOWERS AND AFTERNOON THUNDERSTORMS ACROSS
THE CWA FOR SATURDAY AND SUNDAY AS UPPER LEVEL TROUGH MOVES ACROSS
WYOMING AND ONTO THE PLAINS.  BREEZY CONDITIONS WILL ALSO OCCUR WITH
THE PASSAGE OF THE TROUGH.

.CYS...
WY...NONE.
NE...NONE.
