.DISCUSSION...
MID LEVEL THETA-E RIDGE AXIS HAS AN EWD POSITION TODAY WHICH EXTENDS
ACRS ERN NM S INTO THE TRANS PECOS. REMNANT MCV/S WERE NOTED EARLIER
THIS MORNING...ONE ACRS THE LOWER TRANS PECOS AND ANOTHER IN SE NM.
A WEAKNESS IS NOTED IN 5H HEIGHTS ON NAM12 WHICH IS OPTIMISTIC IN
DEVELOPING PRECIP TODAY ACRS PB. WEAK SFC TROF REMAINS W WITH WEAK
5H WLY WINDS. ECMWF HAS BEEN VERY PERSISTENT TOO IN DEVELOPING
PRECIP ACRS PB TODAY. THUS SCT POPS ARE SUFFICIENT WITH HIEST POPS
WARRANTED ACRS MTNS AND SE NM...ISOLD/SLGHT CHC ELSEWHERE. 12Z MAF
SOUNDING SHOWS PW/S OVER 1.5" AND WITH MENTIONED LIGHT WINDS AT
5H STORM MOVEMENT MAY BE ON THE SLOW SIDE AND AT LEAST LOCALLY
HEAVY RAIN IS A CONCERN. 0-6KM BULK SHEAR DOES INCREASE TO 20-25KT
BY 21Z PER NAM12/GFS SO A FEW STRONG STORMS WILL POSSIBLE TOO.
CENTER OF THE SUBTROPICAL RIDGE WILL APPEAR ACRS SRN NM TUE WHICH
WILL HOLD A WEAK W-NW MID LEVEL COMPONENT ACRS NW CWFA AND AS SUCH
THAT WILL BE THE FAVORED AREA FOR PRECIP TUE PM. POPS ARE ORIENTED
IN THAT FASHION AND ONLY MINOR CHANGES ARE NEEDED. WED STR BUILDS
NWD INTO CNTRL NM WHICH FAVORS MORE OF NE MID LEVEL WIND ACRS PB
AND N ACRS SE NM SO AGAIN BEST CHANCE OF TSTMS WILL BE ACRS THE
NW...BUT EVEN THAT WILL BE LOW END SLGHT CHANCE. VERY SIMILAR
PATTERN THUR. NOT A LOT OF CHANGE IN 85H TEMPS TUE-THUR WITH U20S
C ACRS PB AND AROUND 30C ACRS UPPER TRANS PECOS/SE NM. CLOUDS IN
THE AFTERNOON TUE ACRS NW CWFA MAY HELP TEMPER HIGHS A FEW DEGREES
BUT WED/THUR PARTLY CLOUDY SKIES AT BEST FOR ALL AREAS. 85H
THERMAL RIDGE TO BE A LITTLE MORE PROMINENT FRI SO HOT DRY
CONDITIONS WILL CONTINUE. SAT A STRONG MID LEVEL TROF WILL PASS
INTO THE GREAT LAKES REGION PUSHING A FRONT S INTO PANHANDLE...BUT
MOSTLY LIKELY NOT ENUF PUSH TO MAKE IT INTO PB...POSSIBLY NEARING
THE N SUN PM IF ENUF CONVECTION CAN DEVELOP ALONG FRONT IN THE
PANHANDLE. SUNDAY/MONDAY LOCATION OF STR IS IN QUESTION AND ATTP
WILL GO WITH A PERSISTENCE FORECAST.
