19Z UPPER AIR AND SURFACE ANALYSIS SHOWS A 500 MB SHORTWAVE TROUGH
LOCATED ACROSS THE NORTHERN PLAINS DOWN TO THE COLORADO ROCKIES WITH
PVA COMING INTO THE PANHANDLE OF NEBRASKA. AT THE SURFACE A SLOW
MOVING 1011 MB SURFACE LOW HAS MOVED INTO NORTHEAST NEW MEXICO AND A
WIND SHIFT LINE AHEAD OF THE TROUGH IS LOCATED ROUGHLY ALONG AND
WEST OF HIGHWAY 283.
TONIGHT THE MAIN FEATURE OF INTEREST WILL BE A COLD FRONT THAT IS
USHERED IN BY THE FAST MOVING UPPER LEVEL TROUGH. AS THE TROUGH
MOVES EASTWARD DURING THE EVENING HOURS WE SHOULD SEE THE FRONT
QUICKLY SWEEP THROUGH WESTERN KANSAS BETWEEN SUNSET AND MIDNIGHT.
850 MB WINDS ARE FORECAST TO INCREASE TO 40 KTS ALONG AND EAST OF
HIGHWAY 283 AND SURFACE WINDS SHOULD PICK UP TO 15-25 MPH WITH GUSTS
UP TO 30 MAINLY ALONG AND EAST OF HIGHWAY 283. THE BAND OF MID AND
HIGH LEVEL CLOUDS SHOULD QUICKLY ERODE WITH UPCOMING SUBSIDENCE BY
SUNRISE AND THIS SHOULD ALLOW TEMPERATURES TO FALL IN THE THE
NBM25TH PERCENTILE RANGE WHICH WILL BE THE LOWER TO MID 20S.
WINDS SHOULD DIMINISH DURING THE DAY WITH A SURFACE HIGH MOVING INTO
CENTRAL KANSAS BY EARLY AFTERNOON AND WITH 850 MB TEMPERATURES
HOVERING AROUND 0 (C) WITH THE COLDEST AIR IN CENTRAL KANSAS HIGHS
WILL RANGE FROM THE MID TO UPPER 40S IN THE CENTRAL AND EAST TO THE
LOW 50S NEAR THE COLORADO BORDER.
LOWS WEDNESDAY NIGHT SHOULD MODERATE A BIT AS WINDS TURN BACK TO THE
SOUTHWEST AND A MILDER 850 MB AIRMASS MOVES INTO THE CENTRAL PLAINS.
THIS WILL LEAD TO A BRIEF WARMUP ON THURSDAY BEFORE ANOTHER LONGWAVE
ROUGH IN THE NORTHERN PLAINS USHERS IN A COLD FRONT THURSDAY NIGHT.
WITH LITTLE TO NO MOISTURE WITH THE FROPA WE HAVE HIGH CONFIDENCE OF
NO PRECIPITATION DEVELOPING.
LONG RANGE ENSEMBLES KEEP UP BASICALLY PRECIP FREE THROUGH AT LEAST
NEXT MONDAY AND ONLY A HANDFUL OF SOLUTIONS HINT AT ANY PRECIP
CHANCES FOR THE MIDDLE OF NEXT WEEK.
AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/
ISSUED AT 519 PM CST TUE DEC 17 2024
VFR CONDITIONS WILL PREVAIL IN VICINITY OF ALL TAF SITES THROUGH
EARLY WEDNESDAY. LIGHT NORTHERLY WINDS WILL INCREASE TO AROUND
15 TO 25KT WITH GUSTS UP TO 35KT GENERALLY AFTER 03-06Z AS A
PRESSURE GRADIENT TIGHTENS ACROSS WESTERN KANSAS IN WAKE OF A
COLD FRONT PUSHING SOUTHEAST THROUGH WESTERN OKLAHOMA. WINDS ARE
THEN EXPECTED TO SUBSIDE THROUGH MID/LATE WEDNESDAY MORNING AS
SURFACE HIGH PRESSURE BUILDS IN ACROSS THE HIGH PLAINS OF WESTERN
KANSAS.
