AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 205 PM MDT WED JUN 15 2005 .SHORT TERM...UPPER RIDGE WILL REBUILD OVER THE CWA TONIGHT AS A SHORT WAVE INDUCES AN MCS OVER CENTRAL NEBRASKA. UPPER RIDGE WILL REMAIN CENTERED OVER THE FORECAST AREA THURSDAY AND A SHORTWAVE WILL MOVE INTO THE WESTERN PORTION OF THE CWA IN THE AFTERNOON. LOW LEVEL MOISTURE WILL BE LIMITED TONIGHT AND THURSDAY...BUT MID LEVEL MOISTURE WILL REMAIN OVER THE AREA. LIS WILL BE FROM -3 TO -5 IN THE NEBRASKA PANHANDLE THIS EVENING...WITH CAPE VALUES OVER 1000 J/KG. THETA E RIDGE AXIS WILL BE ALONG THE WY/NEB AT 00Z THIS EVENING.

BY MIDNIGHT...SHOWERS SHOULD LINGER ACROSS THE EASTER PORTION OF THE NEBRASKA PANHANDLE...WHILE CONDITIONS IMPROVE ACROSS THE REST OF THE AREA. THURSDAY LOOKS LIKE A REPEAT OF TODAY...AND LIS WILL BE FORM -4 TO -6 EAST OF THE LARAMIE RANGE WITH CAPE VALUES OVER 2000 J/KG. BELIEVE ANOTHER ROUND OF SEVERE WEATHER WILL BE LIKELY EAST OF THE LARAMIE RANGE THURSDAY AFTERNOON. HIGH TEMPERATURES WILL BE FROM 5 TO 10 DEGREES ABOVE NORMAL. WITH THE SATURATING RAINS OF THE PAST COUPLE OF WEEKS...WILL HAVE TO WATCH THE STRONGER THUNDERSTORMS FOR THE POSSIBILITY OF FLASH FLOODING...ESPECIALLY ACROSS THE SOUTHEAST PORTION OF THE CWA. .LONG TERM...FOR THURSDAY NIGHT THROUGH SATURDAY...ANY SHOWER AND THUNDERSTORM ACTIVITY WHICH DEVELOPS THURSDAY EVENING WILL DECAY QUICKLY AND MOVE OUT OF THE AREA BY MIDNIGHT. DEEP SOUTHWEST FLOW CONTINUES WITH WEST COAST CUTOFF CONTINUING TO MIGRATE SOUTH ALONG THE OREGON COAST. KEPT LOW POPS IN FOR FRIDAY AFTERNOON BUT MAINLY OVER THE MTNS. SATURDAY WILL BE DRY DUE TO MID LEVEL WARMING/SUBSIDENCE WHICH PLACES CAP OVER LOWER ATMOSPHERE. TEMPS AROUND 5 TO 10 DEGREES ABOVE NORMAL FRIDAY AND SATURDAY. FOR SUNDAY THROUGH WEDNESDAY...RIDGE AXIS ALOFT WILL EXTEND FROM THE SOUTHERN HIGH PLAINS TO THE GREAT LAKES SUNDAY THROUGH TUESDAY. DURING THE SAME TIME AN UPPER LEVEL TROUGH WILL BE ALONG THE WEST COAST. IN BETWEEN...THE CWA WILL BE IN SOUTHWEST WIND FLOW ALOFT.

AT THIS TIME IT APPEARS THAT A STATIONARY FRONT WILL BE OVER CENTRAL OR NORTHERN WYOMING AND THEN BACK INTO THE GREAT BASIN...ALMOST PARALLELING THE FLOW ALOFT. WAVES DEVELOP ON THE FRONT AT TIMES FOR SUNDAY THROUGH WEDNESDAY. A SURFACE LOW PRESSURE TROUGH WILL EXTEND INTO WESTERN NEBRASKA...WITH THE BOUNDARY LAYER MOIST AND UNSTABLE AHEAD OF THE FEATURE.
