AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
536 PM MDT SUN MAY 20 2012

.UPDATE...
ISSUED AT 524 PM MDT SUN MAY 20 2012

SENT EVENING UPDATE TO DECREASE CLOUD COVER AND REMOVE MENTION OF
THUNDERSTORMS OVER COLORADO AS DIURNAL CONVECTIVE PUFS ARE
EXPECTED TO DIMINISH AS THE SUN SETS AND VERY LIGHT SHOWERS ARE
DISSIPATING AS THEY MOVE OVER THE EASTERN COLORADO PLAINS.

&&

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 1238 PM MDT SUN MAY 20 2012

ONLY FORECAST CONCERN WILL BE THE POSSIBILITY OF ISOLATED
THUNDERSTORMS IN THE AFTERNOON AND EARLY EVENING HOURS IN THE
WESTERN PARTS OF THE FORECAST AREA. UPPER RIDGING WILL BE DOMINANT
ALOFT...BUT WITH STRONG SURFACE HEATING ON THE HIGHER TERRAIN OF
COLORADO CONVECTIVE TEMPERATURES SHOULD BE REACHED. CUMULUS FIELD
ALREADY SHOWING UP ON VISIBLE SATELLITE THIS AFTERNOON IN
NORTHEAST COLORADO. 0-6KM MEAN WINDS ARE EAST AT AROUND 15KTS
SO ANYTHING THAT DEVELOPS COULD MAKE IT INTO THE WESTERN FORECAST
AREA BEFORE DISSIPATING WITH LOSS OF DAYTIME HEATING THIS EVENING.
THIS PATTERN IS REPEATED ON MONDAY AFTERNOON...BUT WITH A SUBTLE
EASTWARD SHIFT IN THE SURFACE INSTABILITY AXIS. INVERTED-V
SOUNDINGS BOTH DAYS SUGGEST GUSTY WINDS WILL BE POSSIBLE NEAR ANY
THUNDERSTORM WHICH DEVELOPS.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 228 PM MDT SUN MAY 20 2012

THE RIDGE MOVES EAST FROM THE ROCKIES AND INTO THE PLAINS MONDAY
NIGHT/TUESDAY. THE RIDGE SHIFTS EAST TUESDAY NIGHT WITH WESTERLY
FLOW OVER THE PLAINS THROUGH WEDNESDAY NIGHT. SURFACE HIGH PRESSURE
WILL DRIFT EAST MONDAY NIGHT. A TROUGH WILL MOVE INTO EASTERN
COLORADO TUESDAY AND REMAIN THERE THROUGH WEDNESDAY.

PLAN TO ADD SLIGHT CHANCE POPS TO THE EASTERN COLORADO ZONES MONDAY
EVENING. THERE IS A BOUNDARY WEST OF THE FA AND THERE IS SOME WEAK
FORCING WITH CAPE OF AROUND 1000 J/KG SO CANNOT RULE OUT THE
POSSIBILITY OF THUNDERSTORMS MOVING INTO THE EASTERN COLORADO ZONES
DURING THE EVENING. PLAN TO REMOVE POPS TUESDAY AFTERNOON DUE TO
LACK OF MOISTURE. SOUNDINGS INDICATE A VERY DRY LAYER BELOW 550MB.
SUBSIDENCE AND LACK OF MOISTURE WILL KEEP POPS NIL TUESDAY NIGHT.
THERE IS SOME FORCING NOTED NEAR A TROUGH IN EASTERN COLORADO
WEDNESDAY AFTERNOON SO HAVE KEPT SLIGHT CHANCE/CHANCE POPS IN THE
NORTHWEST FA.

MIN TEMPERATURES WILL VARY FROM THE MID 50S MONDAY NIGHT TO THE
UPPER 50S/LOWER 60S TUESDAY NIGHT. MAX TEMPERATURES WILL RISE TO
NEAR RECORD TUESDAY AND THEN COOL TO THE MID 80S WEDNESDAY.

FOR WEDNESDAY NIGHT THROUGH SUNDAY...SOUTHWEST FLOW CONTINUES ACROSS
THE CENTRAL THROUGH THIS PART OF THE FORECAST WITH A TROUGH OVER THE
NORTHWEST CONUS. THIS TROUGH WILL SHIFT EAST FRIDAY WHILE ANOTHER
TROUGH DIGS SOUTH ALONG THE WEST COAST AND THEN LIFTS NORTHEAST INTO
THE NORTHERN ROCKIES SATURDAY/SUNDAY. SURFACE LOW PRESSURE WILL MOVE
EAST ACROSS KANSAS WEDNESDAY NIGHT. ANOTHER AREA OF LOW PRESSURE
WILL MOVE INTO SOUTHEAST COLORADO THURSDAY AND THEN MOVE SOUTH INTO
THE TEXAS PANHANDLE THURSDAY NIGHT. HIGH PRESSURE WILL BUILD INTO
NORTHWEST KANSAS FRIDAY THROUGH SATURDAY. THIS AREA OF HIGH PRESSURE
WILL DRIFT EAST SUNDAY WITH LOW PRESSURE MOVING INTO EASTERN
COLORADO.

NUMEROUS SHORTWAVES MOVING THROUGH THE SOUTHWESTERLY FLOW WILL BRING
AT LEAST A SLIGHT CHANCE TO CHANCE OF THUNDERSTORMS EVERY DAY EXCEPT
FRIDAY WITH SUBSIDENCE OVER THE REGION. MAX TEMPERATURES WILL RANGE
FROM THE LOW/MID 80S TO THE UPPER 80S BY SUNDAY. MIN TEMPERATURES
WILL VARY FROM THE LOWER 50S IN EASTERN COLORADO TO THE MID 60S IN
THE EASTERN FA BY FRIDAY.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z MONDAY EVENING)
ISSUED AT 524 PM MDT SUN MAY 20 2012

VFR CONDITIONS THROUGH THE TAF PERIOD AT MCK AND GLD WITH ONLY A
FEW CLOUDS AND SOUTH WINDS INCREASING AFTER 12Z MONDAY AS A
SURFACE TROUGH BEGINS TO DEEPEN ALONG THE FRONT RANGE.

&&

.FIRE WEATHER...
ISSUED AT 228 PM MDT SUN MAY 20 2012

RELATIVE HUMIDITY VALUES DROP TO AROUND 15 PERCENT TUESDAY
AFTERNOON IN EASTERN COLORADO BUT WIND GUSTS ARE ONLY ABOUT 20
MPH. FURTHERMORE FUELS SHOULD BE AS GREEN AS THEY NORMALLY GET IN
SPRING ACROSS THE AREA. DO NOT SEE A NEED FOR ANY HIGHLIGHT
ESPECIALLY SINCE WINDS/RH ARE MARGINAL FOR ONLY A FEW HOURS AND
FUELS ARE GREEN.
