AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND
229 AM MST TUE MAR 7 2000

...POTENTIALLY STRONG THUNDERSTORMS ACROSS THE TRI-STATE AREA TODAY
AND TONIGHT. ALSO STRONG NW WINDS ARE POSSIBLE WEDNESDAY...

ATTM ISOLD/WDLY SCT TSRA WERE MVG RAPIDLY ACRS THE SW FA. THESE TSRA
WERE MVG NE ALONG A DRY LINE WHICH WAS ROUGHLY FROM NORTON KS
AND EXTENDED WEST TO COLBY THEN SW INTO SE COLORADO. DEW POINTS
SOUTH OF THIS LINE WERE IN THE 50S AND LOOKING AT THIS LATEST
GUIDANCE INDICATED INCREASING CAPE VALUES ACRS ALL THE CWA AND WERE
HIEST BY 07/12Z. BELIEVE THIS DRY LINE WILL SHIFT WWARD AND WITH
LAPSE RATES BETWEEN 7/5H WERE GREATER THAN 8C/KM. BY MORNING THUS
INCREASING THE CHANCE FOR TSTORMS ACRS THE AREA.

A MAJOR LOW OVER NW MEXICO ATTM WILL PUSH NE AND STRENGTHNS AS IT
APPROACHES THE FA TODAY. ALL MODELS WERE UNDERFORECASTING THE LOW LVL
MOISTR ATTM BUT THE AVN/ETA WERE SLIGHTLY BETTER AND MAY LEAN TOWARD
THIS SOLN ESPECIALLY AFTER ANALYZING THE LATEST DATA...THE GLD NGM
TMPS WERE FORECAST IN THE 40S WHEN THEY ARE IN THE UPPER 50S ATTM.

AS THE MAJOR LOW MOVES NE TODAY TMPS DIF BETWEEN 850/5H WERE
GREATER THAN 30C AND LAPSE RATES STILL WERE BETTER THAN 7C/KM ACRS
THE FA. THE ETA WAS ALITTLE STRONGER AND SLOWER WITH THIS LOW WHERE
THE AVN MOVES IT ACRS THE CWA BY MIDNIGHT. NEVERTHELESS...BEFORE
THE LOW MOVES EAST OF THE FA...ALONG WITH ITS COLD FRONT...A 5H/COLD
POCKET ALONG WITH VERY HIGH LAPSE RATES PUSHES ALONG THE S/E FA
TONIGHT. IT APPEARS THE MOST SIGNIFICANT CONVECTIVE ACTIVITY WILL BE
JUST SOUTH AND EAST OF THE FA AND MAY MINIMIZE CONVECTION ACRS THE
CWA. STILL...AFTER ANALYZING FORECAST SOUNDINGS AND TIME SECTIONS...
SOME VERY GOOD OMEGAS AHEAD OF THE PASSING COLD FRONT...ALONG WITH
SIGNIFICANT LOW LVL MOISTR COMBINING WITH THE AFOREMENTIONED MAY
PRODUCE STRONG TSRA TONIGHT. ALSO WITH THE FAST MVG STORMS...STRONG
WINDS GUSTS ARE POSSIBLE AND WITH LOWERING FREEZING LVLS...HAIL IS
ALSO POSSIBLE.

AS THE LOW STRENGTHNS AND PASSES TO THE EAST OF THE FA WEDNESDAY
MORNING...VERY STRONG NW SURFACE WINDS WILL FOLLOW. SUSTAINED WINDS
IN EXCESS OF 40MPH WITH HIER GUSTS WINDS ARE A STRONG POSSIBILITY
FOR WEDNESDAY. WITH THE POTENTIALLY ACTIVE STRONG TSTORM DAY TODAY...
AND VERY STRONG WINDS WEDNESDAY...WILL LIKELY ISSUE A SPS.

WRAP AROUND MOISTR PERSISTS WEDNESDAY AND TMPS WILL BE NOTICEABLY
COLDER. THE AVN 850/TMPS REMAIN ABOVE 4C THRU THE DAY AND EXPECT THE
PCPN TO REMAIN LIQUID ATTM ALTHO...THE COLDER ETA HAD SNOW AMTS ACRS
THE OUR NORTHERN FA. I DO FEEL TMPS WILL BE TOO WARM BUT WITH THE
COOLER TO COLDER AIR ADVTNG SOUTH MAY MENTION A MIXTURE ACRS THE N
CWA WED. THE VERY WINDY TO STRONG NORTHWEST WINDS SHUD BEGIN TO
DECREASE ACRS THE WESTERN FA WED NIGHT BUT PERSIST OVR THE EASTERN
CWA.

FOR THURSDAY THE WINDS SHUD FINALLY DECREASE ACRS ALL THE CWA BUT
THE COOLR TMPS WILL LINGER ACRS THE EAST. WARMER AFTN TMPS ARE
LIKELY ACRS THE WEST AS 850/TMPS REBOUND TO NEAR 10C BY LATE AFTN.

A WEAK DISTURBANCE MOVES ACRS THE CWA FRIDAY AND MAY BRING OUR NEXT
CHANCE FOR PCPN WITH THE POSSIBLY OF SOME -SN OVR THE N FA WHERE
850/TMPS FALL BELOW 0C. THIS DISTURBANCE MOVES EAST SATURDAY BUT THE
COOLR TMPS REMAIN ALONG WITH SOME MID LVL CLOUD COVER.

.GLD...NONE.
