.DISCUSSION...
/ISSUED 401 AM CDT SAT AUG 15 2015/
STRONG UPPER LEVEL RIDGING IN PLACE OVER THE SOUTHERN ROCKIES AND
4-CORNERS REGION...CREATED A NUMBER OF RECORD HIGH TEMPERATURES
ACROSS THAT REGION. NORTH OF THERE...A DISTURBANCE MOVING EASTWARD
ACROSS THE WESTERN CANADIAN/UNITED STATES BORDER IN THE PREVAILING
WESTERLY FLOW...SHOULD HELP INDUCE A PATTERN CHANGE ACROSS THE
CONUS DURING THE WEEKEND AND NEXT WEEK. IN THE MEANWHILE...A
NORTHERLY FLOW AROUND THE DESERT SW LOW WAS SENDING VARIOUS UPPER
LEVEL DISTURBANCES FROM THE US/CANADIAN BORDER TO THE DEEP SOUTH.

A STATIONARY FRONT ORIENTED ALONG THE GULF COAST HAS KEPT DEEPER
MOISTURE WELL TO OUR SOUTH OVER THE PAST FEW DAYS. THIS BOUNDARY
SHOULD BECOME MORE DIFFUSE OVER THE WEEKEND...AS A PREDOMINATING
SOUTHERLY FLOW TAKES PLACE OVER THE SE STATES. THIS CHANGE WILL
BRING DEEPER MOISTURE FROM THE GULF INLAND...ALONG WITH A CHANCE
OF RAIN FOR THE UPCOMING FORECAST PERIOD.

THE DESERT SW UPPER RIDGE WILL SLOWLY WEAKEN ACROSS THE LOWER-48
DURING THE COURSE OF THE WEEKEND AND EARLY NEXT WEEK...AS A SERIES
OF SYSTEMS IN THE NORTHERN STREAM MOVE ACROSS THE NW CONUS. THIS
WILL INDUCE TROUGHING ACROSS THE CENTRAL CONUS...AND ALLOW DEEPER
MOISTURE FROM THE GULF TO BE TRANSPORTED NORTHWARD. THUS A GENERALLY
UNSETTLED PATTERN IS IN THE WORKS FOR THIS UPCOMING FORECAST
PERIOD...WITH SOME CHANCE OF SHOWERS/THUNDERSTORMS EACH DAY. FOR
TODAY...ISOLATED LIGHT SHOWERS IN PROGRESS AROUND THE REGION SHOULD
DISSIPATE SOMEWHAT THIS MORNING...BUT WILL RE-FORM AND BECOME MORE
SCATTERED IN THE AFTERNOON...THANKS TO STRONG DAYTIME HEATING AND
INTERACTION WITH EXISTING BOUNDARIES. AS IS USUALLY THE CASE WITH
CONVECTION...THE STRONGER STORMS COULD PRODUCE LOCALLY HEAVY RAINS
AND GUSTY WINDS. RAIN CHANCES WILL DECREASE THIS EVENING WITH A LOSS
OF DAYTIME HEATING. THERE IS STILL TO MUCH INSTABILITY TO REMOVE
ISOLATED SHOWER CHANCES SUNDAY/SUNDAY NIGHT.

SOMEWHAT BETTER RAIN CHANCES ARE FORECAST ON MONDAY...AS A WEAK
FRONT ACCOMPANYING AN UPPER SYSTEM APPROACHES FROM THE NW. MODEL
GUIDANCE IS IN GENERALLY GOOD AGREEMENT KEEPING THE FRONT NW OF THE
REGION. STAYED IN THE HIGHER CHANCE RANGE (50 PERCENT)...RATHER THAN
GO TO LIKELY POPS MON... CONSIDERING THE PRECIP CHARACTER WILL BE
SHOWERY. OUTPUT FROM THE GFS INDICATED PRECIP WATER AMOUNTS WILL
RISE INTO 1.8 TO 2.0 INCH RANGE NEXT MON/TUE. THUS SOME STORMS COULD
BECOME STRONG...WITH FREQUENT LIGHTNING...GUSTY WINDS...AND LOCALLY
HEAVY RAINFALL A POSSIBILITY. FURTHER INTO NEXT WEEK...AN UNSETTLED
PATTERN CONTINUES...WITH SOME CHANCE OF SHOWERS AND THUNDERSTORMS.
STAYED WITH MOSTLY CHANCE-RANGE POPS FOR THE NEXT WORK WEEK.

.AVIATION...
FOR 12Z TAFS...CONVECTION HAS BEEN GRADUALLY INCREASING ALONG THE
I-65 CORRIDOR OVER THE PAST HR OR SO...AND SOME OF THIS ACTIVITY HAS
MANAGED TO CLIP THE KHSV TERMINAL. GIVEN THE ORIENTATION OF THE
PRECIP BANDS...THE KHSV AIRPORT MAY SEE SOME MORE RAIN OVER THE NEXT
COUPLE OF HRS...BEFORE THE PRECIP SHIELD SPREADS OUT TO COVER MORE
OF NRN AL. OTHER THAN SOME BRIEF VIS REDUCTIONS NEAR THE KHSV TERMINAL
EARLY THIS MORNING...VFR CONDS ARE GENERALLY XPCTED THROUGH THE TAF
PERIOD GIVEN THE LOW CONFIDENCE IN PLACEMENT/TIMING OF ADDITIONAL
CONVECTIVE BANDS LATER TODAY/TONIGHT.
