PREV DISCUSSION... /ISSUED 333 PM CDT THU APR 17 2014/

DISCUSSION...
SOME LOCATIONS SEEING A FAIR AMOUNT OF SUNSHINE TODAY (PARTICULAR-
LY THE NERN CWA) BUT CLOUDS HAVE HELD FIRM ELSEWHERE. AS SUCH THE
CHANCE OF PCPN (ALBEIT LIGHT) IS EXPECTED TO LINGER THROUGH EARLY
EVENING TONIGHT COURTESY OF A SECOND WEAKER SHORTWAVE. THE TIMING
OF THIS DISTURBANCE...COMBINED WITH THE MORE STABLE CONDITIONS IN
THE WAKE OF THE EARLIER CONVECTION SHOULD HELP KEEP ANY SHRA THAT
DOES FORM GENERALLY ISOLATED.

CLEARING SKIES TONIGHT/GENERALLY QUIET WX PATTERN ON TAP THE NEXT
DAY OR SO GIVEN THE BRIEF RIDGING ALOFT (AND REINFORCING COOL/DRY
AIRMASS FROM A WEAK COOL FRONT OVERNIGHT TONIGHT). HOWEVER MODELS
REMAIN ON TRACK FOR THE RETURN OF INCREASING TEMPS/LOW LEVEL MOI-
STURE AND A RETURN OF LOW POPS FOR THE LATTER PART OF THE WEEKEND
(SAT NIGHT/SUN). BEST DYNAMICS WITH THE NEXT UPPER TROF SHOULD BE
WELL N/NE OF THE CWFA (AS GUIDANCE HAS BEEN TRENDING THIS WAY). A
BRIEF (BUT MUCH FLATTER) RIDGE ALOFT TO WILL BE IN PLACE TO START
THE WEEK WITH ANOTHER (PERHAPS STRONGER) UPPER LEVEL STORM SYSTEM
SET TO MOVE INTO THE NRN/CNTRL PLAINS STARTING THE MIDDLE OF NEXT
WEEK. OTHERWISE WARMER AND LIKELY MORE HUMID NEXT WEEK. 41

MARINE...
WINDS/SEAS STILL NEAR BORDERLINE CONDITIONS FOR CAUTION CRITERIA
SO WILL LET THOSE FLAGS CONTINUE TO FLY UNTIL NEXT UPDATE.
IMPROVING CONDITIONS EXPECTED THEREAFTER AS WEAK FRONT/HIGH PRES
WILL MOVES IN LATE TONIGHT CAUSING WINDS TO GRADUALLY BACK TO THE
NNE THEN NE. LIGHT ONSHORE RESUMES SATURDAY AND CONTINUES THRU
NEXT WEEK. SLIGHT INCREASE DURING THE 2ND HALF AS GRADIENT
TIGHTENS. 47
