AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND
132 PM MST TUE MAR 7 2000

...STRONG TO SEVERE THUNDERSTORMS LIKELY ACROSS EASTERN PORTIONS OF
CWA INTO THIS EVENING...

RAPIDLY DEEPENING LOW IN EASTERN COLORADO AND GOOD THETA E RIDGE
EXTENDING ALONG THE KS/CO BORDER WAS PRESENT AT 18Z. DRYLINE IS
PUSHED ALL THE WAY BACK TO THE FRONT RANGE.

MOST MODELS INITIATING FAIRLY WELL WITH UPPER LEVEL FEATURES.
HOWEVER...AT THE SURFACE ETA DOING A FAR SUPERIOR JOB IN TRACKING
LOW IN EASTERN CO OUT THROUGH 18Z. AVN IS MUCH TOO FAR NORTH AND NGM
IS TOO SHALLOW AND EXTENDS LOW PRESSURE CENTER TOO FAR NORTH. WILL
DEFINITELY GO WITH THE ETA WITH ITS MUCH BETTER HANDLING AND RUN TO
RUN CONSISTENCY FOR THIS PACKAGE.

TONIGHT AS THE LOW PRESSURE BEGINS ITS NORTHEAST JOURNEY FROM
EASTERN COLORADO A DRY LINE WILL PUSH FROM EAST OF THE FRONT RANGE
EAST. THIS WILL PUSH EAST THROUGH A STRONG THETA E RIDGE AND AN AREA
OF STRONG CAPES THAT WERE NEAR 2000 BEFORE NOON. THESE THUNDERSTORMS
MAY LINGER INTO THE EARLY MORNING IN THE EAST AS H7 VORT CENTER
PUSHES THROUGH WITH STRONG ARE OF THETA E CONVERGENCE. DRY LINE IS
MORE DIFFUSE IN THE TRI STATE AREA AT THAN FARTHER SOUTH AS THETA E
RIDGE EXTENDS INTO THE LOWER PANHANDLE OF NE.

SYSTEM REMAINS FAIRLY STRONG AS SYSTEM PUSHES NORTHEAST AND WINDS
COME AROUND TO THE NORTHWEST...POSSIBLY REACHING ADVISORY LEVELS.
DURING THE DAY H85 TEMPS REMAIN IN THE 6C TO 8C RANGE WITH BL DPTS
IN THE LOW TO MID 30S. H85-H5 OMEGA FIELD WEAKEN AND WITH NOT MUCH
DYNAMIC COOLING BULK OF PRECIP SHOULD REMAIN LIQUID. AFTER 18Z H85
TEMPS NEAR 2C AND BELOW AND LIGHT SNOW ARRIVES IN THE NE
COUNTIES...WITH LITTLE IN THE WAY OF ACCUMULATIONS...ESPECIALLY WITH
SOIL TEMPS IN THE UPPER 40S.

WEDNESDAY NIGHT GRADIENT LOOSENS AS COLDER AIR PUSHES IN THE AREA.
LIGHT WINDS AND H85 TEMPS RANGING FROM -2C TO -6C SHOULD ALLOW TEMPS
TO DROP INTO THE LOWER 20S WITH A LIGHT DOWNSLOPE FLOW.

AVN COMES MORE IN LINE WITH THE ETA OUT TO 48HRS WITH THE ETA BEING
A LITTLE COOLER. THE THE UNUSUALLY WARM SOIL TEMPS WILL LEAN TOWARD
THE WARMER FAN TEMPS FOR THURSDAY AND OUT.

MODELS IN DISAGREEMENT AS TO THE TRACK BUT NOT THE TIMING OF THE
SYSTEM MOVING THROUGH ON FRIDAY. MRF IS MUCH FARTHER NORTH AND
COOLER THAN THE ECMWF...WITH THE AVN STARTING TO BRING THIS SYSTEM
DOWN. AT THIS TIME WILL GO WITH A MIDDLE GROUND TRACK FOR THIS SYSTEM
AS FEEL THAT THE ECMWF IS TOO AMPLIFIED WITH THIS PATTERN. THIS WILL
BEAR SCRUTINY AS THE MORE SOUTHERLY DEEP TRACK WILL BE A GOOD SNOW
PRODUCER...AS COMPARED TO THE MRF TRACK WHICH WILL BRING ANOTHER
ROUND OF STRONG THUNDERSTORMS. WILL GO A CHANCE OF SHOWERS ON FRIDAY
ON SATURDAY TO LEAVE MANEUVERING ROOM FOR LATER PACKAGES.

.GLD...NONE.
