.PREV DISCUSSION... /ISSUED 957 PM CDT TUE APR 15 2014/

DISCUSSION...
CLEAR SKIES OVERHEAD...BUT THIN CIRRUS SKIRTING NORTHERN TIER.
SOME OF THIS COULD DISAPPEAR WITH OUR PWAT AT TWO TENTHS. MANY
LOCALES NORTH AND EAST HAVE BEEN CALM SINCE SUNSET AND DEW POINTS
HAVE TAKEN A HIT IN THE WRONG DIRECTION FROM FRESH VAPOR OUT OF
THE SOIL. WE STILL SEE SCATTERED LOW 30S AND WITH TEMPS FALLING
THE RESIDUAL HEAT FROM THE DAY IS GOING TO RUN OUT AS THE TOP SOIL
CONTINUES TO COOL. 18Z MODEL DEW POINTS ARE ALMOST UNREASONABLE
COMPARED THESE MID EVENING READINGS...BUT THINKING IS THAT
OVERNIGHT WE WILL FALL BACK THROUGH THE DEW POINT. TOUGH
CALL...BUT HAVE DECIDED TO LEAVE WELL ENOUGH ALONE IN THAT EVENT.
THE SECOND NIGHT IS TYPICALLY THE COLDEST NIGHT FOR OUR EAST AND
WE WILL GO WITH THAT FOR PATTERN RECOGNITION. THE HIGHEST PRESSURE
AROUND IS JUST TO OUR EAST AT GREENVILLE MS AND TALLULAH LA AT
1025 MB. SO THERE IS STILL SOME LIGHT NE WINDS IN NORTH CENTRAL LA
FOR PERHAPS A LITTLE MIXING...BUT COLD AIR MASS MAY HAVE MODIFIED
JUST A LITTLE TOO MUCH TODAY...THAT COUPLE WITH THE EARLY CALM
THIS EVENING. ONLY CHANGE TO WEATHER GRIDS IS PUSH BACK PATCHY
FROST FROM MIDNIGHT TO MATCH FREEZE WARNING IN THE WEE HOURS PRIOR
TO DAYBREAK. AT ANY RATE...BETTER SAFE THAN SORRY WITH THE LAST
GASP OF WINTER IS THE FOUR STATE AREA. PLANTS SHOULD BE SAFE FROM
HERE OUT UNTIL NEXT FALL. /24/
