.AVIATION...
FOR THE 12Z TAFS...
ONCE AGAIN IT WILL BE DIFFICULT TO PIN DOWN EXACT TIMING OF TSRA
AT THE TERMINAL SITES. ATMOSPHERE IS VERY UNSTABLE FOR THIS TIME
OF DAY...AND ANY DEVELOPMENT COULD OCCUR QUICKLY. ACTIVE COMPLEX
OF TSRA OVR CNTRL IA LOOKS LIKE IT WILL TRACK JUST NORTH OF KUIN
THIS MORNING. ADDITIONAL SCT TSRA IS DEVELOPING ALONG A LINE FROM
NRN MO SEWD TO NEAR KSTL. WITH THESE TWO REASONS IN MIND...
PROBABLITY IS TOO LOW TO INCLUDE A TEMPO FOR TS...THOUGHT DO HAVE
VCTS AT KUIN GOING THROUGH 15Z. MAY NEED TO AMEND QUICKLY IF TSRA
BEGINS TO TRACK FARTHER SEWD. OUTFLOW FROM COMPLEX IS ALSO
TRAVELING SWD ACROSS IA AND MAY REACH KUIN AROUND 13Z WHICH MAY
TURN WINDS OUT OF THE NORTH TEMPORARILY. WITH SCT SHRA/TSRA
ONGOING OVR SWRN MO...HAVE INCLUDED A VCSH AT KCOU. EXPECT A COLD
FRONT TO MOV SWD ACROSS REGION LATE TODAY AND THIS EVENING. HAVE
TIMED SCT TSRA THAT I EXPECT TO DEVELOP ALONG THE FRONT WITH PRO30
GROUPS AT THE TERMINALS LATER TODAY/THIS EVENING. OTHERWISE...
WINDS WILL SHIFT FROM SW TO N-NE BEHIND THE FRONT WITH THE
POSSIBLITY OF STRATUS AND RESULTING MVFR CIGS SETTING IN LATER
TONIGHT.
