AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX

.DISCUSSION...
CENTER OF UPPER LEVEL HIGH WILL CONTINUE TO PUSH BACK TO THE WEST AND
IT WILL SET UP SHOP OVER THE 4 CORNERS REGION BY LATE TONIGHT. AND
THERE IS WHERE IT WILL SIT THROUGH THE REST OF THIS FORECAST.
AGAIN...BELIEVE THAT THE NORTHWEST FLOW ALOFT TO THE EAST OF THIS
HIGH WILL BRING PERIODS OF SHOWERS AND THUNDERSTORMS ACROSS OUR AREA
AS SEVERAL UPPER LEVEL DISTURBANCES PASS THROUGH AND INTERACT WITH
THE LOW LEVEL MOISTURE. HOWEVER...THE DEVIL IS IN THE DETAILS.

TODAY THE MAIN FOCUS FOR SHOWER AND THUNDERSTORM DEVELOPMENT WILL
BE WITH THE CURRENT MCS WHICH IS OVER OUR NORTHWEST CWA. THE MODELS
DISAGREE ON JUST HOW FAR EAST THIS MCS MAKES IT BEFORE IT FALLS
APART. THE NAM MODEL IS MORE AGGRESSIVE IN KEEPING THIS MCS TOGETHER
AS IT MOVES SLOWLY EAST DURING THE DAY. SOME OTHER HIGH RES MODELS
ALSO SUPPORT THE NAM SOLUTION. THE GFS WEAKENS THIS MCS MUCH QUICKER
AND IT DOES NOT BRING IT AS FAR EAST. IF ONE IS TO BELIEVE THE NAM
SOLUTION...THEN THERE COULD BE A LULL IN CONVECTIVE ACTIVITY IN THE
AREA LATE THIS AFTERNOON THROUGH THIS EVENING. IF YOU BELIEVE THE
GFS SOLUTION...THEN CONVECTION REGENERATES OVER THE MOUNTAINS THIS
AFTERNOON AND ANOTHER MCS HEADS THIS WAY THIS EVENING. WE ARE
LEANING TOWARD THE NAM SOLUTION AT THIS TIME AS IT MAY TAKE SOME
TIME FOR NORTHEAST NEW MEXICO AND SOUTHEAST COLORADO TO RECOVER
BEFORE NEW CONVECTION CAN DEVELOP.  AND EVEN IF IT DOES DEVELOP...
IT MAY START OVER THE HIGHEST MOUNTAINS AND WITH THE WEAK FLOW
ALOFT...IT MAY TAKE UNTIL AFTER MIDNIGHT UNTIL IT REACHES OUR
NORTHWEST CWA. ALSO AM A LITTLE CONCERNED ON HOW INTENSE THE
CONVECTION WILL BE IF SOUTHEAST COLORADO AND NORTHEAST NEW MEXICO
ARE STABILIZED DUE TO LINGERING CLOUD COVER TODAY. THEREFORE...WILL
NOT ISSUE A FLASH FLOOD WATCH AT THIS TIME FOR LATER TODAY AND
TONIGHT.

BY TUESDAY NIGHT INTO WEDNESDAY A STRONGER SHORT WAVE TROUGH
APPROACHES THE NORTHEAST CWA...SO THIS MAY BE ANOTHER PERIOD WHERE
HEAVIER RAIN CAN BE BETTER FORECAST.

THE FLOW ALOFT MAY BECOME A LITTLE MORE NORTHERLY BY THIS WEEKEND...
WHICH COULD POSSIBLY KEEP ANY MOUNTAIN CONVECTION TO OUR WEST. NOT
SURE RIGHT NOW IF THIS WILL BE THE CASE...BUT WILL KEEP THE CURRENT
FORECAST BEYOND FRIDAY DRY FOR NOW NONETHELESS.
