AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
1130 AM CDT THU APR 5 2007
.UPDATE...
&&
.DISCUSSION...
WE ARE ISSUING ANOTHER FREEZE WARNING AND FROST ADVISORY ACROSS
THE NORTHERN HALF OF THE FORECAST AREA FOR TONIGHT. THIS WILL BE IN
ESSENTIALLY THE SAME CONFIGURATION AS THE WARNING AND ADVISORY
WHICH EXPIRED THIS MORNING. CRITERIA WAS LARGELY NOT MET THIS
MORNING... AND TOMORROW MAY WELL SEE THE SAME RESULT. GUIDANCE HAS
BEEN RUNNING TOO COLD AND WITH WINDS EXPECTED TO REMAIN UP... AND
COPIOUS CLOUD COVER OVERNIGHT... TEMPERATURES MAY HAVE TROUBLE
DIPPING TO OR BELOW FREEZING. BUT... CANT RULE IT OUT.
AN UPPER LEVEL IMPULSE IS QUITE APPARENT ON SATELLITE IMAGERY
ACROSS KANSAS AND HEADING SOUTHEASTWARD. ASSOCIATED CLOUD COVER
HAS ALREADY BEGUN INCREASING ACROSS THE FORECAST AREA. AS OF
YET... WIDESPREAD PRECIPITATION HAS NOT DEVELOPED WITH THIS
FEATURE IN KANSAS. POPS ACROSS NORTHEAST OKLAHOMA MAY BE TOO HIGH
BUT DECIDED TO RIDE WITH THEM FOR NOW. THE ONLY CHANGE MADE TO PRIOR
FORECAST WAS TO INCREASE CLOUD COVER FOR THE REMAINDER OF THE DAY.
UPDATED PRODUCTS HAVE ALREADY BEEN SENT.

.PREV DISCUSSION... /ISSUED 315 AM CDT THU APR 5 2007/
DISCUSSION...
CANADIAN HIGH PRESSURE SETTLING OVER THE REGION HAS RESULTED LIGHT
WINDS ACROSS THE FA THIS MORNING. UPPER WAVE SEEN OVER ERN IDAHO IN
W/V IMAGERY WILL SLIDE SOUTHEAST TODAY. MODELS DIFFER SOME IN
TIMING...BUT IT APPEARS MOST OF ANY PRECIP WILL HOLD OFF FROM THE
FAR NW SECTIONS OF THE FA UNTIL LATE MORNING (EARLY AFTERNOON?).
HOWEVER...GIVEN CLOUD COVER AND EARLIER ONSET OF PRECIP FALLING
THROUGH THE THE LOWER DEWPOINT AIR....WILL OPT TO FOLLOW A NON
DIURNAL TEMPERATURE TRACE ACROSS FAR NE OK. HAVE ALSO OPTED TO PULL
THE RAIN/SNOW FURTHER SOUTH AS EVAPORATIONAL COOLING EFFECTS WILL DROP
TEMPERATURES FAR ENOUGH TO SUPPORT AT LEAST A RAIN SNOW MIX. THIS
EVENING. REMNANTS OF THIS WEAKENING UPPER FEATURE SHOULD LARGELY BE
SOUTHEAST OF THE AREA AFTER 06Z...BUT WILL CARRY LOW POPS AFTER 06Z
ACROSS THE FAR ERN SECTIONS OF THE FA. MODELS IN DECENT AGREEMENT
THAT THE BULK OF UPPER FLOW ENERGY WILL REMAIN WEST AND SW OF THE AREA
THROUGH THE WEEKEND. AS A RESULT...REINFORCING COLDER AIR WITHOUT
THE BENEFIT OF MUCH CLOUD COVER WILL RESULT IN VERY COLD
TEMPERATURES SATURDAY MORNING...AND THIS MAY BE THE COLDEST MORNING
OF THIS FORECAST CYCLE. HAVE OPTED TO LOWER HIGHS BY SEVERAL DEGREES
ACROSS THE CENTRAL AND EASTERN ZONES. TEMPERATURES ACROSS THE
WESTERN ZONES WILL BE TWEAKED DOWN A LITTLE...AS THOSE AREAS WILL BE
ON THE FRINGE OF POTENTIAL CLOUD COVER. ANOTHER COLD NIGHT SATURDAY
BEFORE A WARMUP COMMENCES FOR THE EARLY PART OF THE WEEK. AT THE
SAME TIME...ANOTHER SYSTEM ORGANIZES TO THE WEST AND WILL BRING RAIN
CHANCES TO THE AREA TUESDAY AND POSSIBLY INTO
WEDNESDAY.
