.SHORT TERM...VALID FOR TDY...SUN...MON...
...WILL BE CANCELING THE WINTER STORM WARNING WITH THIS UPDATE AND
   THE WRKAFP WILL ALSO BE UPDATED...

CHECKING AROUND THE WARNED AREA...CONDITIONS HAVE IMPROVED
SIGNIFICANTLY TO WARRANT CANCELING THE WARNING WITH THE UPDATE INSTEAD
OF LETTING IT EXPIRE ON ITS OWN AT NOON.

NEW ETA IS REASONABLY CONSISTENT WITH THE PREVIOUS RUN AND THE GENERAL
ESSENCE OF THE PRESENT PACKAGE LOOKS GOOD. ITS SIMPLY A MATTER OF FINE
TUNING THE WORDING FOR TODAY. CHB

.LONG TERM...VALID FOR TUE...WED...THU...FRI...

NEW MRF RUN IS VERY CONSISTENT WITH ITS PREVIOUS RUN. IN ADDITION...
MODELS ARE FAIRLY AGREEABLE THROUGH THE PERIOD. A TROUGH IS STILL
EXPECTED TO MOVE ACROSS THE NORTHERN AND EASTERN PORTION OF THE
STATE MON NIGHT INTO TUE. THERE WILL BE AN OUTSIDE CHANCE FOR A
SHOWER AT THIS TIME. THEN A RIDGE WILL BUILD IN FOR TUE AHEAD OF A
WEAK TROUGH THAT IS EXPECTED TO MOVE ACROSS THE CANADIAN BORDER ON WED.
WILL LEAVE CURRENT ISOLATED POPS IN AS THIS IS DAY 6 BUT FEEL THINGS
WILL CONTINUE TO BE DRY. PRESSURE GRADIENT TIGHTENS AGAIN IN THE WEST
FOR FRI SO WINDY CONDITIONS MAY BE POSSIBLE THAT DAY. THIS PATTERN OF A
PREVAILING WEST TO NORTHWEST FLOW WILL LEAVE US IN THE CONTINUED
DOWNSLOPE AND DRY PATTERN THAT WE HAVE EXPERIENCED MOST OF THIS WINTER.
AGREE WITH PREVIOUS SHIFT THAT FMR AND MEX ARE WARMING THINGS UP TO
MUCH AND FAST AS THICKNESS VALUES ONLY LOOK TO BE AROUND THE 535-540DAM
RANGE DAYS 4-6 AND AROUND 545DAM FOR DAY 7. THEREFORE...NO UPDATES
PLANNED.  HOOLEY
