.UPDATE...
SEVERE THUNDERSTORM WATCH 514 HAS BEEN ISSUED FOR WESTERN HALF OF

WITH LARGE HAIL AND GUSTY WINDS. STORMS WILL MOVE THROUGH WEST

.PREV DISCUSSION... /ISSUED 401 AM MDT TUE OCT 20 2015/

SYNOPSIS...
THE NEXT TWO DAYS WILL BE ACTIVE WITH THUNDERSTORMS...A FEW OF
THEM SEVERE WITH LARGE HAIL AND DAMAGING WINDS. THERE WILL ALSO BE
A THREAT OF FLASH FLOODING...MAINLY EAST OF THE RIO GRANDE
WEDNESDAY AFTERNOON AND EVENING. SHOWERS AND THUNDERSTORMS WILL
DECREASE FROM WEST TO EAST ON THURSDAY...WITH SEVERAL DAYS OF DRY
WEATHER FOLLOWING...ALTHOUGH THERE WILL BE A SLIGHT CHANCE OF
SHOWERS IN THE SACRAMENTO MOUNTAINS ON THE WEEKEND.

DISCUSSION...
THE POTENTIAL SEVERE WEATHER EPISODE WE'VE BEEN ADVERTISING FOR
THE PAST SEVERAL DAYS IS STILL ON SCHEDULE. A WEST COAST TROUGH
IS CURRENTLY IN THE PROCESS OF CLOSING/CUTTING OFF AND SHOULD SIT
OVER ARIZONA THIS EVENING THROUGH WEDNESDAY EVENING. WITH SOUTHERN
NM AND FAR WEST TX BEING UNDER THE FRONT SECTOR OF THAT LOW THERE
WILL BE PLENTY OF DYNAMICS...MOISTURE AND VERTICAL WIND SHEAR TO
GO AROUND. WE WILL ALSO BE UNDER THE LEFT EXIT REGION OF A JET
MAX ALOFT. MULTICELL SEVERE COMPLEXES ARE POSSIBLE WITH THE
ABUNDANCE OF SPEED SHEAR...WHILE EAST OF THE RIO GRANDE
DIRECTIONAL SHEAR WILL ALLOW FOR A FEW SUPERCELLS AS WELL. THUS
THERE SHOULD BE REPORTS OF LARGE HAIL...WIND DAMAGE...AND FLASH
FLOODING TUESDAY AFTERNOON THROUGH WEDNESDAY NIGHT. THE PEAK FLOOD
THREAT SHOULD BE WEDNESDAY AFTERNOON AND EVENING...MAINLY EAST OF
THE RIO GRANDE. AND THOUGH THE THREAT IS LOW...A TORNADO OR TWO IS
NOT OUT OF THE QUESTION.

ON THURSDAY THE UPPER LOW WILL OPEN UP AND MOVE EAST...TAKING THE
SUFFICIENT MOISTURE...COLD AIR ALOFT AND FAVORABLE DYNAMICS WITH
IT. SHOWERS AND THUNDERSTORMS SHOULD BE ENDING FROM WEST TO EAST.
IT IS POSSIBLE THAT THE EASTERN PORTIONS OF HUDPSETH AND OTERO
COUNTIES COULD STILL EXPERIENCE SOME STRONG STORMS THURSDAY
AFTERNOON. A TRAILING UPPER TROUGH...WEAKER AND DRIER WILL PASS
OVER THE AREA LATE FRIDAY AND SATURDAY...BUT ONLY THE MOUNTAINS
SHOULD SEE ANY SHOWERS FROM THIS. HOWEVER THE MODELS WERE EARLIER
CLOSING THIS FEATURE OFF AND TAKING IT FURTHER SOUTH FOR A BETTER
THREAT OF PRECIPITATION SO THE CONFIDENCE LEVEL FOR A MAINLY DRY
WEEKEND IS NOT HIGH. BUT OVERALL THE PATTERN WILL TRANSITION INTO
A PROGRESSIVE WEST TO NORTHWEST FLOW INTO NEXT WEEK WHICH SHOULD
BE DRY AND SLIGHTLY COOLER THAN NORMAL.

AVIATION...VALID 20/12Z-21/12Z... UPPER LEVEL TROUGH WILL BE
DIGGING THROUGH CA OVER NEXT 12 HOURS AND CUTOFF OVER SWRN AZ BY
21/00Z. THIS WILL BRING THREAT FOR STRONG TO SEVERE STORMS TO
REGION AFT 18Z. P6SM SCT-BKN060-080 BKN250 FOR MUCH OF FORECAST
PD. SFC WINDS S TO SW 5-15KTS. ISOLATED LOWLAND AND SCT MTN
VRB20G35KTS 1- 3SM TSRA BKN040-050 THRU 18Z. AFT 18Z STORMS WILL
BECOME SCT TO NMRS ACROSS AREA WITH 1SM +TSRAGR BKN020-030 AND
WIND GUSTS OVER 50KTS POSSIBLE. STORM MOTION EXPECTED TO BE
210/25-30KTS.

FIRE WEATHER...
UPPER TROUGH WILL BE DIGGING THROUGH CALIFORNIA TODAY AND CUTOFF
OVER SOUTHWEST ARIZONA BY THIS EVENING. THIS LOW WILL BRING
SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS TO THE REGION
TODAY WITH THE AREA SHIFTING TO EASTERN HALF OF FORECAST AREA
WEDNESDAY AND MAINLY MOUNTAINS THURSDAY. ANOTHER TROUGH WILL MOVE
THROUGH SATURDAY AND MAY TAP ENOUGH MOISTURE FROM THE EAST FOR A
FEW MORE SHOWERS AND THUNDERSTORMS. OVERALL...TEMPERATURES WILL
RUN NEAR NORMAL WITH RELATIVE HUMIDITIES ABOVE 30 PERCENT FOR THE
LOWLANDS FOR THE UPCOMING WEEK
