LTL BETTER THAN PREV FCST. CUD SEE MARGINAL WND ADVY CRITERIA THIS
AFTN W OF JAMES RVR...BUT WL NOT ISSUE ADVY ATTM. HAVE BUMPED UP
TEMPS A FEW DEG ESPEC W WHERE HIGHS MAY HIT 70.

I29 THIS AFTN AND THEN DECREASING DURING THE EVE. STG NW WINDS WL
DEVELOP AGAIN LATE TONIGHT.

&&

.PREVIOUS DISCUSSION...
CLD CVR OTHER THAN CI WILL MOVE EWD OUT OF ERN PART OF FCST AREA BY
15Z OR SO. OTRW GNLY A FEW HI CLDS TDA WITH A FEW SCT MID CLDS DVLPG
THIS AFTN...CLD CVR WILL BE THIN ENUF AND DOWN ENUF FOR MOSUNNY.
TEMPS WILL BE MILD...PRETTY CLOSE TO GUIDNCE HIGHS OR A TAD WARMER
IN SOME CASES.

CDFNT SHUD MOVE SWD/SEWD ACRS FCST AREA TNGT AS WE HAVE BEEN GOING
FOR. TIMING WILL BRING DECENT COLD ADVECTN BCMG STGR 06Z-12Z. THO
AIR WILL BE GETTING PRETTY WELL MIXED...STG WNDS DVLPG UPSTAIRS WILL
NOT REALLY BE COUPLED TILL WNDS START TO GET STG SUN MRNG. THUS SFC
TEMPS WILL GET A LTL CHC TO COOL FROM WHAT WUD OTRW BE MILD MIXED
LEVELS LATE TNGT...THEN WARMING SUN MRNG WITH INCRG MIXG AND SOME
HEATING DESPITE COLD ADVECTN...SO DO NOT QUITE LOOK FOR FALLING
TEMPS THRU THE DAY SUN...THO HIGHS SHUD BE REACHED ARND NOON OR

NOW TO WINDS...STG WINDS ALOFT WILL MIX DOWN LATE SUN MORNING AND
GET REALLY STG BY THE START OF SUN AFTN. WIND ADVY A GIVEN TO BE

BETTER ISSUANCE WILL COME THIS AFTN WHEN TIMING OF THE VERY STG WNDS
AND STRENGTH BCM BETTER DEFINED. DO NOT THINK WE WILL REACH HI WIND
WARNING CRITERIA AS APPARENTLY OVERDONE FWC GUIDNCE SHOWS. WINDS
SHUD TAPER OFF STEADILY SUN EVE.

REST OF FCST PRETTY BORING. HOW MANY WAYS CAN U SAY GOING MILD AND
DRY AFTER A COLD BUT CALMING MON? CURRENT HI TEMPS PROJECTIONS FOR
LATER IN THE WEEK GOING INTO THE 50S AND EVENTUALLY SOME 60S WEST
AND SOUTH LOOK A LITTLE CONSERVATIVE...BUT WILL LEAVE ALONE FOR NOW.
THE EARLIER KINK IN THE WARMING PD PRESENTED BY 12Z ECMWF IN THE
FORM OF A BRIEF MODERATELY COLD SHOT FOR THU HAS GONE BYE BYE WITH
THE 00Z RUN. DONT SEE ANY PCPN THREAT ON ANY MODEL THRU FCST PD. IN
FACT GFS KEEPS THIS REGIME GOING AS FAR AS U CAN SEE...TO DAY 16.
CONSIDERING TIME OF YEAR AND JUST FINISHED HEAVY RAIN EVENT...I DONT
THINK ANYONE WILL BE COMPLAINING.
