AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
513 AM CDT TUE AUG 12 2008
.UPDATE...
SCATTERED LIGHT SHOWERS HAVE DEVELOPED OVER SOUTHEAST KANSAS AND
WILL LIKELY REACH NORTHEAST OKLAHOMA EARLY THIS MORNING. RUC HINTS
AT THIS...SO WILL GO AHEAD AND INCLUDE SOME LOW POPS AND ISSUE NEW
SET OF ZONES. EXPECT PRECIPITATION TO BE LIGHT AND SHOULD NOT LAST
THE MORNING.
ALSO WILL UPDATE THE FLASH FLOOD WATCH TO DROP SOME OF THE WESTERN
COUNTIES. /02

.PREV DISCUSSION... /ISSUED 408 AM CDT TUE AUG 12 2008/
DISCUSSION...
TIMING OF CURRENT RAIN THROUGH THE FORECAST AREA IS PROBLEMATIC
THIS MORNING...BUT HAVE MADE THE EFFORT. EXPECT PRECIP TO MOVE
THROUGH THE FSM AREA AROUND 7 AM AND HIGH PROBABILITY IT WILL LEAVE
THE ALL OF THE FORECAST AREA RAIN FREE BEFORE NOON.
UPPER TROUGH PUSHES WELL THROUGH THE AREA LATER TODAY...AND SHOULD
LEAD TO DRIER WEATHER THE NEXT COUPLE OF DAYS. ISSUE IS A POSSIBLE
MCS DEVELOPING WEDNESDAY NIGHT...SLIDING DOWN THROUGH KANSAS INTO
NORTHERN OKLAHOMA LATE AND INTO EARLY THURSDAY MORNING. GFW HAS
THE SYSTEM FARTHER WEST...BUT NAM AND ECMWF AGREE IT WILL AFFECT
NORTHEAST OK. HAVE INCLUDED SOME SMALL POPS FOR THAT CONTINGENCY.
MORE IMPORTANT SYSTEM COMES OVER THE WESTERN RIDGE AND DROPS SOUTH
INTO THE PLAINS ON THURSDAY NIGHT AND FRIDAY. BOTH GFW AND ECMWS
DEVELOP THIS INTO A CLOSED LOW OVER THE CENTRAL PLAINS OVER THE
WEEKEND. THIS SHOULD MAKE THE WEATHER UNSETTLED...BUT LIKELY
COOLER THAN NORMAL. HAVE ADJUSTED TEMPS AND POPS FOR THIS.
WENT COOLER THAN MAV MOS THE NEXT COUPLE OF DAYS DUE THE AMOUNT OF
RAIN THAT HAS FALLEN. EXPECT THE MOS WILL USE CLIMATOLOGY FOR SOIL
TEMPS FOR ANOTHER COUPLE OF DAYS AND WILL NOT ACCOUNT FOR
EVAPORATION. ALSO...MOS HAS HAD A COLD BIAS AT NIGHT...PROBABLY
BECAUSE IT THINKS THE GROUND SHOULD BE DRY. THAT NOT THE
CASE...PLUS TRANSPIRATION FROM PLANT AT NIGHT SEEMS TO HAVE BEEN
RAISING THE DEW POINTS. SO...HAVE ADJUSTED HIGHS DOWN AND LOWS UP
A LITTLE. ALSO...CLEAR SKIES AND LIGHT WINDS TUESDAY NIGHT SHOULD
LEAD TO POSSIBILITY OF RADIATION FOG. HAVE ONLY MENTIONED IT FOR
NOW.
