BEFORE 12Z. WITH BOUNDARY LAYER WINDS 10 KNOTS OR LESS OVER THE
EASTERN TERMINALS...AM GOING TO GO PESSIMISTIC ON THE KALI AND
KVCT TERMINALS...MENTIONING 1/2SM (TEMPOS) BFR 14Z...WITH 1-2SM
OVERALL. BRIEF MVFR BR POSSIBLE AT KCRP...WITH NO FOG EXPECTED AT
KLRD (THINK DEW POINT DEPRESSIONS TOO HIGH). AFTER THAT...COULD
HAVE BRIEF MVFR CIGS BEFORE 16Z AT EASTERN TERMINALS...BUT WILL
NOT FORECAST AS EXPECT GENERALLY VFR. WINDS WILL BE LIGHT SOUTH OR
SOUTHWEST...THEN BECOMING MORE SOUTHEAST EITHER LATE IN THE

.PREV DISCUSSION... /ISSUED 243 PM CDT WED JUL 29 2015/

SHORT TERM...MID/UPR LVL RIDGE WHICH HAS DOMINATED OUR WEATHER
THIS PAST MONTH WILL PIVOT WWD TOWARD THE SRN ROCKIES IN THE NEXT
48 HRS ALLOWING A LITTLE DEEPER MOISTURE TO NOSE INTO THE COASTAL
BEND. PWATS ARE PROGGED TO CLIMB TO 1.9" THU AND 2.2" FRI WITH A
DECREASING CAP. THUS WILL MAINTAIN SLIGHT CHC/CHC POPS FOR
THU/FRI. DUE TO THE INCREASED MOISTURE THE DIURNAL TEMP RANGE WILL
BE LESSENED BY A FEW DEGREES. MAINTAINED MENTION OF PATCHY FOG FOR
OVERNIGHT TONIGHT/EARLY THU PER NAM/GFS FCST SOUNDINGS INDICATING
LIGHT ONSHORE WINDS AND DRY AIR ABOVE SFC SHALLOW BOUNDARY
LAYER/CAPPING INVERSION.

LONG TERM (FRIDAY THROUGH WEDNESDAY)...THE UPPER LEVEL RIDGE TAKING
STRONGHOLD FOR THE PAST SEVERAL DAYS SLOWLY LIFTS TO THE NORTH-
NORTHWEST ALLOWING FOR AN UPPER TROUGH TO PUSH A FRONTAL BOUNDARY
THROUGH THE EASTERN ZONES...WITH THE MODIFIED TAILED EXTENT
STRETCHING INTO THE NORTHWESTERN GULF. THIS WILL BRING AN INCREASE
IN MOISTURE WITH PWATS MEASURING OVER 2 INCHES. MOISTURE INCREASE IS
MORE NOTICED IN THE MIDLEVELS...SO AM EXPECTING AN INCREASE IN CLOUD
COVERAGE SPREADING FROM EAST TO WEST...BUT THE WEAK BOUNDARY MAY BE
ENOUGH FORCING FOR SHOWERS AND A FEW EMBEDDED THUNDERSTORMS TO
EXIST...PRIMARILY ACROSS THE EASTERN HALF OF THE CWA. THE MAIN
CAVEAT TO ALL OF THIS IS THE LAYER OF WARM TEMPERATURES AT H85. THE
LINGERING BOUNDARY SHOULD KEEP RAIN CHANCES THROUGH
SATURDAY...ALTHOUGH THE BEST FORCING WILL LIKELY BE ACROSS THE
SOUTHERN ZONES AS THE UPPER RIDGE BEGINS TO SLOWLY PUSH BACK TO THE
SOUTH...SHUNTING THE MOISTURE OUT OF THE REGION. DRY AND HOT
CONDITIONS WILL RESUME FOR EARLY NEXT WEEK.
