FIRE WEATHER PLANNING FORECAST FOR GRASS...LNF
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM
324 PM MDT TUE OCT 27 2009

FORECAST IS BASED ON REQUEST TIME OF 1456 MDT ON OCTOBER 27.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

...WIND ADVISORY IN EFFECT UNTIL 2 PM MDT WEDNESDAY...

.DISCUSSION...
APPROACHING STORM SYSTEM WILL BRING INCREASING WEST TO SOUTHWEST
WINDS OVERNIGHT...THOUGH CANYON ORIENTATION WILL TEND TO FAVOR A
MORE WESTERLY DIRECTION.  TONIGHT IS A TOUGH CALL WITH RESPECT TO
WINDS.  WHILE THEY WILL BE INCREASING ALOFT THROUGH THE NIGHT...
COOL AIR DRAINAGE MAY SETUP A SHALLOW NOCTURNAL INVERSION IN THE
CANYON.  ON THE OTHER HAND...A PRE-EXISTING INVERSION AROUND THE
9-10 KFT MSL LEVEL MAY HELP ENHANCE SURFACE WINDS ON THE DOWNSLOPE
SIDE OF THE SACS.  MOST LIKELY SCENARIO IS FOR ERRATIC PERIODS
OF GUSTY WINDS AND PERIODS OF MUCH LIGHTER FLOW OVERNIGHT.  THERE
IS ONLY A VERY SLIGHT CHANCE OF A SHOWER BEFORE DAWN...WITH
IMPROVING PRECIP CHANCES DURING THE DAY TOMORROW...BUT WITH
CONTINUED BREEZY DOWNSLOPE CONDITIONS.

FREQUENT FEEDBACK/OBSERVATIONS WOULD BE MOST APPRECIATED SHOULD
THE FIRE CONTINUE THROUGH THE NIGHT...ESPECIALLY GIVEN THE TERRAIN
AT THE FIRE LOCATION DO NOT HESITATE TO CONTACT US IF CONDITIONS
CHANGE.
