AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
549 PM MDT FRI OCT 24 2014

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 151 PM MDT FRI OCT 24 2014

WITH A MID-LEVEL RIDGE IN PLACE ACROSS THE CENTRAL AND SOUTHERN
PLAINS THE DRY AND MILD PATTERN WILL CONTINUE THROUGH THE WEEKEND. A
WEAK COLD FRONT WILL MOVE SOUTH ACROSS THE NORTHERN AND CENTRAL
PLAINS...STALLING OUT JUST NORTH/NORTHEAST OF THE CWA TOMORROW.

TODAY...MOSTLY SUNNY AND RECORD-BREAKING WARMTH. AS OF THE EARLY
AFTERNOON AT LEAST ONE RECORD HIGH TEMPERATURE HAS BEEN TIED AND A
FEW OTHERS ARE A FEW DEGREES SHY OF RECORD VALUES. RAP ANALYSIS
DEPICTS 850MB TEMPS ON THE WARMER SIDE OF GUIDANCE...AND MORNING
TEMPS ROSE ACCORDINGLY. SOME EARLY CLOUD COVER ALONG/EAST OF HIGHWAY
83 LIMITED HEATING THIS MORNING...BUT UNDER NEAR-FULL SUNSHINE EARLY
THIS AFTERNOON TEMPS ARE NEAR FORECAST VALUES. DEW POINTS HAVE BEEN
MARKEDLY DRIER THAN MOST ALL GUIDANCE EXCEPT FOR THE HRRR WHICH HAS
BEEN DEPICTING WHAT SEEMED THIS MORNING TO BE A VERY AGGRESSIVE DROP
IN DEW POINTS...IN THE 20S F ACROSS EASTERN COLORADO. WINDS ARE
LIGHT /LESS THAN 10MPH/ SO THANKFULLY FIRE WEATHER CONDITIONS ARE
NOT A CONCERN TODAY.

TONIGHT...CLOUDS CLEAR OUT BUT WARM AIRMASS REMAINS IN PLACE. LOW
TEMPS WILL BE IN THE MID/UPPER 40S...ABOUT 10 DEGREES ABOVE NORMAL.
WINDS WILL BE LIGHT AND VARIABLE IN DIRECTION. WITH DRY AIR MOVING
IN FOG IS OF NO CONCERN.

TOMORROW...SATURDAY...ANOTHER DRY AND MILD DAY. TEMPS WILL NOT BE AS
HOT AS FRIDAY AS COLD FRONT APPROACHES FROM THE NORTH. GOOD MODEL
AGREEMENT...850MB TEMPS IN THE LOW 20S C LEADING TO HIGHS WELL ABOVE
NORMAL...IN THE LOW TO MID 80S. WINDS OUT OF THE SOUTHEAST AT 10-15
KTS WITH GUSTS TO 25 KTS. RECORD HIGHS MAY BE BROKEN...SEE CLIMATE
SECTION FOR DETAILS.

.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 217 PM MDT FRI OCT 24 2014

NAM/SREF ARE SHOWING MOISTURE RETURN EAST OF SURFACE TROUGH OVER
THE EASTERN PART OF THE CWA SATURDAY NIGHT INTO SUNDAY...WHICH
COULD LEAD TO FOG DEVELOPMENT. NAM/SREF ARE SHOWING REDUCED VIS IN
THESE AREAS...SO I INTRODUCED PATCHY FOG MENTION OVER THE
NORTHEAST PART OF CWA.

GUIDANCE CONTINUES TO BE IN DECENT AGREEMENT AT LEAST THROUGH
EARLY NEXT WEEK ON THE LARGE SCALE PATTERN WITH RIDGE KEEPING
UNSEASONABLY WARM TEMPS AND DRY CONDITIONS IN PLACE SUNDAY...AND
A QUICK MOVING POSITIVELY TILTED TROUGH MOVING THROUGH THE
NORTHERN/CENTRAL PLAINS MONDAY-MONDAY NIGHT.

JUST LIKE IN PREVIOUS MODEL RUNS...LIFT IS DECENT...HOWEVER
MOISTURE IS NOT IMPRESSIVE AND I CONSIDERED ONLY HAVING MENTION OF
SPRINKLES AND NO MEASURABLE PRECIP. THERE IS STILL A WEAK PRECIP
SIGNAL ON MOST GUIDANCE...AND I COULDNT RULE OUT A FEW LOCATIONS
GETTING A FEW HUNDREDTHS SO I LEFT SLIGHT CHANCE POPS IN PLACE
MONDAY-MONDAY EVENING. AS THE SURFACE FRONT MOVES THROUGH THE CWA
AND SURFACE GRADIENT INCREASES WE COULD SEE WINDY CONDITIONS
DEVELOP...ESPECIALLY IN THE AFTERNOON. I TRENDED WINDS UP A LITTLE
MONDAY AFTERNOON...BUT AM STILL A LITTLE LOWER THAN WHAT NAM ML
WINDS WOULD INDICATE.

SKIES SHOULD RAPIDLY CLEAR MONDAY NIGHT WITH DECREASING
WINDS...AND LOW TD VALUES IN THE 20S. THIS SHOULD SUPPORT GOOD
RADIATIONAL COOLING AND FROST CHANCES APPEAR TO BE INCREASING. I
KEPT FORECAST IN THE 30-36F RANGE...HOWEVER I COULD SEE A FEW COLD
SPOTS DROPPING TO 28F.

PATTERN SHIFTS TO A BRIEF WESTERLY ZONAL FLOW BEFORE RIDGE
AMPLIFIES OVER THE WESTERN US...RESULTING IN NORTH-NORTHWEST FLOW
OVER THE PLAINS. GUIDANCE GENERALLY SHOWING A SIMILAR
PATTERN...THOUGH THERE ARE SMALLER VARIANCES LIKELY A RESULT OF
WEAK EMBEDDED SHORTWAVES. A VERY DRY AIR MASS IS ADVERTISED...SO
EVEN IF WE DO SE DISTURBANCES PASS THROUGH THE MEAN FLOW I DO NOT
ANTICIPATE PRECIP AND ONLY PASSING HIGH CLOUDS. TEMPS WILL TEND TO
BE JUST BELOW SEASONAL NORMALS AROUND 60F MONDAY-FRIDAY...WITH
WESTERLY FLOW SUPPORTING SEASONAL NORMALS IN THE UPPER 60S/NEAR 70
ON WEDNESDAY.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SATURDAY EVENING)
ISSUED AT 544 PM MDT FRI OCT 24 2014

VFR CONDITIONS ARE EXPECTED WITH CLEAR SKIES THROUGH THE TAF
PERIOD. LIGHT NORTHWEST TO WEST WINDS ARE EXPECTED OVERNIGHT
THROUGH ABOUT 16Z SATURDAY MORNING. BY 19Z WINDS ARE EXPECTED TO
TURN SOUTHEAST BETWEEN 10-15KTS AS A SURFACE LEE TROUGH DEEPENS
ALONG THE FRONT RANGE AND SURFACE HIGH PRESSURE SLIDES FROM THE
NORTHERN HIGH PLAINS INTO THE CENTRAL PLAINS.

.GLD WATCHES/WARNINGS/ADVISORIES...
KS...NONE.
CO...NONE.
NE...NONE.
