AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
200 PM MST THU JAN 25 2007

.SYNOPSIS...A LOW OVER NORTHERN MEXICO WILL TRACK BACK UP THROUGH
EASTERN ARIZONA AND WESTERN NEW MEXICO OVER THE NEXT 36 HOURS. THIS
WILL RESULT IN SOME RAIN AND SNOW SHOWERS MAINLY EAST OF TUCSON...AS
WELL AS GUSTY WINDS IN SOME AREAS. OTHERWISE...AFTERNOON
TEMPERATURES WILL CONTINUE TO WARM AS WE MOVE INTO THE WEEKEND WITH
HIGH PRESSURE NEAR THE WEST COAST.
&&

.DISCUSSION...THAT LOW IS TRACKING BACK AS EXPECTED. IT HAS WOBBLED
BACK INTO NORTHEASTERN SONORA AND IS MOVING TOWARD THE DOUGLAS AREA
TODAY. IT SHOULD LIFT OUT TOWARD THE SOUTHERN PLAINS LATE
FRIDAY...BUT NOT BEFORE BRINGING MORE RAIN AND SNOW SHOWERS TO AREAS
MAINLY EAST OF TUCSON. ISOLATED SHOWER ACTIVITY HAS PUSHED INTO
COCHISE COUNTY FROM THE SOUTHEAST...BUT SNOW LEVELS REMAIN ABOVE
6000 FEET THIS AFTERNOON. A DUSTING WILL BE POSSIBLE ON EASTERN
VALLEY FLOORS TONIGHT...WITH 3 TO 5 INCHES POSSIBLE ABOVE 7000 FEET.
PRIMARY AREA OF CONCERN WOULD BE AROUND THE CHIRICAHUA MOUNTAINS
WHERE BEST DYNAMICS AND TERRAIN EFFECTS COULD COMBINE FOR SNOW
ADVISORY LEVEL SNOWFALLS...INCLUDING EVEN SOME LOWER ELEVATION AREAS.

RIDGE OVER THE WEEKEND FOR A WARMING TREND...BACK TO NEAR OR A
LITTLE ABOVE CLIMO. GRADIENT WILL QUICKLY RELAX TO TYPICAL DIURNAL
TRENDS. WEAK IMPULSE AROUND TUESDAY COULD DIRTY THINGS UP WITH SOME
MID TO CIRRUS LEVEL CLOUDS...OTHERWISE STILL DRY. NEXT CHANCE AT
SIGNIFICANT WEATHER WOULD BE WITH A SYSTEM TOWARD THE SECOND HALF OF
THE NEW WEEK. EARLY INDICATIONS POINT TOWARD A COLD BUT DRY INLAND
TRAJECTORY.

&&

.AVIATION...CURRENT TAF AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT
WEATHER AT KTUS.
&&

.TWC WATCHES/WARNINGS/ADVISORIES...NONE.
