THAT...CLEAR AND WARM WITH LOWS GENERALLY IN THE UPPER 60S TO NEAR
70.

UPPER HIGH BUILDS ACROSS THE AREA THROUGH FRIDAY WITH MOISTURE
SOURCES DECREASING...HENCE LITTLE IN THE WAY OF PRECIP.

QUESTION BECOMES HIGHS AND LOWS. DIURNAL RANGES THE PAST FEW DAYS
HAVE BEEN 25 TO 30 DEGREES OVER THE EASTERN CWA WITH NEARLY 35
DEGREES OVER THE WEST. SEE NO REASON TO DEVIATE BASED ON CURRENT
PATTERN. WILL FOLLOW THE AVN 2M TEMP GUIDANCE FOR HIGHS...CUTTING
ABOUT 5 DEGREES OFF THE 2M ETA HIGHS.

FOR TONIGHT/THURSDAY NIGHT...LOWS IN THE MIDDLE 60S/65 TO 70. SOUTH
WINDS 10 TO 20 MPH UNDER A CLEAR SKY.

THURSDAY...SUNNY AND HOT. 2M ETA AND FWC TEMPS AGREE ON AFTERNOON

FRIDAY...SUNNY AND HOT. RECORD TEMPS IN JEOPARDY WOULD AGAIN BE YUMA
(101 IN 1985) WITH OTHER SITES AROUND 105. WILL GO WITH HIGHS
AGAIN OF 100 TO 102.

IN THE EXTENDED...QUESTION OF THUNDERSTORM POTENTIAL ARISES AS
FORECAST K-INDICES APPROACH LEVELS SUGGESTIVE FOR THEIR
DEVELOPMENT. ONLY QUESTION WILL BE WHETHER WE'RE CAPPED OR NOT.
THROUGH THE PERIOD...500MB HEIGHT CENTER BASICALLY OVER THE
AREA WITH WEAK SHORTWAVES AROUND. AXIS OF HIGHER K-INDICES AND
TOTALS-TOTALS CENTERED OVER THE CENTRAL AND EASTERN CWA WHERE 700MB
TEMPS ARE LOWER (+13C TO +15C) AND 700MB DEWPOINTS ARE +1C TO +3C.
FORECAST SOUNDINGS ACROSS THIS AREA SUGGEST CONVECTIVE TEMPS AROUND
105F. BASED ON THAT I'LL KEEP IT DRY AND HOT.
