TONIGHT AND TOMORROW...
NOT MUCH TO TALK ABOUT IN THE SHORT TERM PERIOD. A 1018MB SFC HIGH
HOVERING OVER THE SOUTHERN PLAINS WILL SHIFT SOUTHWARD OVER THE
NORTHERN GULF LATER THIS EVENING. THIS WILL HELP KEEP WEATHER
CONDITIONS QUIET THROUGH THE OVERNIGHT PERIOD. MID/HIGH CLOUD COVER
WILL START TO INCREASE SLIGHTLY OVER OUR CWA LATER TONIGHT,
ESPECIALLY IN THE NORTH. HREF GUIDANCE IS STARTING TO SHOW SOME LOW
PROBABILITIES (AROUND 20-30%) FOR PATCHY FOG BY EARLY SUNDAY
MORNING. EXPECT NIGHTTIME TEMPERATURES TO DROP INTO THE LOW/MID 60S
AREAWIDE. GLOBAL GUIDANCE SHOWS A MIDLEVEL SHORTWAVE TROUGH
TRAVERSING THE WESTERN FLANK OF A LONGWAVE TROUGH. THIS WILL ALLOW
FOR SOUTHERLY MOISTURE FLOW TO RETURN TO THE AREA HEADING INTO
SUNDAY. THIS COULD RESULT IN A SLIGHT CHANCE OF SCATTERED SHOWERS
AND T-STORMS SUNDAY AFTERNOON. EXPECT AFTERNOON HIGHS IN THE MID 80S
AREAWIDE.
THE FORECAST FOR THE LONG TERM PERIOD REMAINS ON TRACK WITH NO
CHANGES MADE. PLEASE SEE THE PREVIOUS FORECAST DISCUSSION FOR MORE
DETAILS.
THROUGH NEXT WEEK...
THE SEASONALLY MOIST AIRMASS PERSISTS AS AN UPPER RIDGE BUILDS OVER
THE AREA. DESPITE THIS RIDGE, A FEW DIURNALLY DRIVEN SHOWERS AND
STORMS WILL BE POSSIBLE EACH AFTERNOON. AN UPPER LOW OVER BAJA WILL
EJECT ACROSS THE CENTRAL CONUS MID TO LATE NEXT WEEK AND WILL WORK
TO FLATTEN THE UPPER RIDGE. THIS WEAKENING WILL ALLOW FOR AN
INCREASE IN RAIN AND STORM CHANCES THAT WILL PERSIST THROUGH MID TO
LATE NEXT WEEK. FUTURE GUIDANCE IS STARTING TO SHOW SOME SIGNALS OF
INCREASING STORM POTENTIAL FOR THE LATE WEEK/WEEKEND TIMEFRAME.
TRENDS WILL CONTINUED TO BE MONITORED AS WE GET CLOSER. /SAS/CR/
