AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
238 AM MDT THU MAR 26 2015

.SHORT TERM...(TODAY THROUGH SATURDAY NIGHT)
ISSUED AT 238 AM MDT THU MAR 26 2015

AS OF 3 AM CDT...2 AM MDT...SKIES ACROSS THE TRI-STATE REGION ARE
MOSTLY CLEAR. TEMPERATURES DROPPED INTO THE MID 20S TO LOW 30S. A
FEW READINGS IN THE LOW 20S ARE BEING OBSERVED AS WELL. WINDS ARE
LIGHT AND VARIABLE. AT THE SURFACE...AN AXIS OF HIGH PRESSURE IS
DRAPED OVER THE HIGH PLAINS. A SURFACE LOW PRESSURE IS LOCATED OVER
MONTANA AND WYOMING...SLIDING SOUTHEAST. ALOFT...NORTHWEST FLOW
EXTENDS FROM SOUTHWEST CANADA TO THE HIGH PLAINS. A SHORTWAVE TROUGH
IS VISIBLE IN WATER VAPOR IMAGERY OVER NORTHERN MONTANA.

OVERALL...QUIET WEATHER IS ANTICIPATED OVER THE NEXT FEW DAYS. THERE
IS A SLIGHT CHANCE OF RAIN/SNOW SHOWERS TONIGHT INTO FRIDAY MORNING.
OTHER THAN THIS SLIM CHANCE...DRY AND WARMER WEATHER IS FORECAST.

FOR TODAY...MAIN WEATHER STORY IS INCREASING CLOUD COVER AND
BREEZY/WINDY CONDITIONS EXPECTED TO DEVELOP. FORECAST GUIDANCE
INDICATES AMPLE MIXING BEFORE ARRIVAL OF DENSER CIRRUS. MOST MODELS
SUGGEST 700 MB WINDS APPROACHING 35-40 KNOTS BY AFTERNOON. IN
ADDITION...THE SURFACE LOW OVER MONTANA SURGES SOUTH OVER THE HIGH
PLAINS. WE SHOULD OBSERVE RAPID PRESSURE FALLS THIS AFTERNOON AS THE
LOW DEEPENS. THEREFORE...EXPECTING BREEZY/WINDY CONDITIONS WITH
WINDS SUSTAINED 15-30 MPH...GUSTING 40 TO POSSIBLY 45 MPH. HIGH
TEMPERATURES SHOULD REACH THE LOW 60S ALTHOUGH THERE ARE SOME
CONCERNS THAT THE BREEZY/WINDY CONDITIONS MAY HOLD TEMPERATURES DOWN
A COUPLE DEGREES.

TONIGHT INTO TOMORROW MORNING...A SHORTWAVE TROUGH SLIDES THROUGH
THE REGION. GLANCING AT THE JET STREAM...VORTICITY AND ISENTROPIC
FIELDS...AM NOT OVERLY IMPRESSED WITH HOW THE FEATURES ARE COMING
TOGETHER FOR POSSIBLE PRECIPITATION. FEEL THAT THE BEST LIFT/FORCING
REMAINS EAST OVER EASTERN NEBRASKA AND KANSAS. ANOTHER CONCERN
TONIGHT IS TEMPERATURES AS DENSE CLOUD COVER SHOULD KEEP
TEMPERATURES FROM FALLING TOO MUCH. REGARDLESS...FORECAST SOUNDING
PROFILES SUGGEST THERE MAY BE ENOUGH COOLING TO ACHIEVE A RAIN/SNOW
MIX WITH ANY SHOWERS. DECIDED TO KEEP POPS MINIMAL AND FORECAST A
SLIGHT CHANCE FOR PRECIPITATION MAINLY NORTH/EAST OF A HAIGLER
NEBRASKA TO NORTON KANSAS LINE. ANY PRECIPITATION THAT FALLS WILL BE
LIGHT...ONLY A FEW HUNDREDTHS AT MOST. IF SNOW SHOWERS ARE ABLE TO
OCCUR...DO NOT FORESEE ANY ACCUMULATIONS WITH SURFACE TEMPERATURES
THAT ARE QUITE WARM.

ANOTHER BREEZY DAY IS LIKELY FRIDAY AS A SIMILAR SETUP TO TODAY`S
CONDITIONS SHOULD DEVELOP. HOWEVER...THIS TIME AM NOT ANTICIPATING A
DEEPENING LOW WITH RAPIDLY FALLING PRESSURES AS FORECAST TODAY. A
NOTICEABLE WARMUP IS ALSO ANTICIPATED FRIDAY AS TEMPERATURES ALOFT
INCREASE 5-7 DEGREES CELSIUS. THIS WARMING TREND CONTINUES INTO
SATURDAY...THE WARMEST DAY OF THE SHORT-TERM FORECAST PERIOD. HIGHS
SATURDAY SHOULD REACH THE UPPER 70S TO LOW 80S...WELL ABOVE NORMAL
FOR THIS TIME OF YEAR. RECORD HIGHS SATURDAY ARE IN THE MID 80S TO
LOW 90S. A "SOFT RECORD" OF 83 DEGREES AT BURLINGTON COLORADO MAY BE
VULNERABLE.

.LONG TERM...(SUNDAY THROUGH THURSDAY)
ISSUED AT 222 AM MDT THU MAR 26 2015

FOR THE EXTENDED PERIOD...WARM AND DRY CONDITIONS WILL ENSUE OVER
THE AREA AS AN UPPER RIDGE OVER THE WESTERN PORTION OF THE COUNTRY
WILL KEEP WNW FLOW OVER THE AREA WITH HIGH PRESSURE AT THE SURFACE.
SOME MODEL DIFFERENCES WITH THE GFS/ECMWF DURING THIS TIME AS GFS
WANTING TO SHIFT CUTOFF LOW OVER THE DESERT SOUTHWEST SOUTH OF THE
REGION...COMBINING IT WITH AN INVERTED SURFACE TROUGH TO BRING IN
PRECIPITATION. THE LATEST ECMWF KEEPS THIS SHORTWAVE TOO FAR SOUTH
DESPITE SURFACE FRONT WORKING OFF THE ROCKIES. WILL OPT TO KEEP CWA
DRY FOR THIS PASSAGE AS SYSTEM SEEMS TOO FAR SOUTH TO BRING INTO
AREA TO BE EFFECTIVE IN OVERCOMING DRY LAYER NEAR SURFACE. BUT GOING
ITO WEDNESDAY AND THURSDAY OF NEXT WEEK...BOTH MODELS SHOW A COUPLE
MORE SHORTWAVES THAT HAVE POTENTIAL FOR BRINGING A ROUND OF RAIN TO
THE AREA. FIRST SYSTEM HAS MOST OF UPPER SUPPORT WELL TO THE NORTH
GIVING NE ZONES BEST CHANCES FOR -RW LATE WEDNESDAY. THE SECOND
SYSTEM HAS BETTER CHANCES TO BRING LIGHT RAIN TO ENTIRE REGION.
500/700 MB TROUGHS DO SWING ACROSS THE TRI STATE REGION...WITH
SURFACE LOW OFF TO OUR SE...WHICH WILL ALLOW FOR SYSTEM TO WRAP
AROUND SOME MOISTURE FROM THE GULF ENHANCING CHANCES FOR RAIN...WITH
BEST CHANCE SIN EASTERN ZONES CLOSEST TO SURFACE LOW. LOOKING FOR
HIGH TEMPS TO INCREASE IN THE SUN-TUES PERIOD FROM THE MID 60S TO
THE LOW TO MID 70S...BUT DROP BACK INTO THE 60S DUE TO INCREASED
CLOUDINESS AND THE CHANCE FOR RAIN. OVERNIGHT LOWS IN THE 30S WITH
SOME 40S MON-TUES NIGHTS.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 1048 PM MDT WED MAR 25 2015

VFR CONDITIONS WILL CONTINUE FOR THE NEXT 24 HOURS AT KGLD AND
KMCK AS THE UPPER TROUGH MOVES EAST OF THE AREA. WINDS WILL
BECOME BREEZY TO WINDY THURSDAY AFTERNOON AS A FRONT BACKS INTO
THE AREA. CLOUDS WILL INCREASE THURSDAY EVENING WITH THE BEST
MOISTURE NEAR KMCK WHERE THERE IS A SLIGHT CHANCE OF LIGHT
SHOWERS.
