318 AM CDT THU SEP 13 2007

.DISCUSSION...
COLD FRONT SHOWING UP WELL ON 88D MOSAIC THIS MORING MOVING ACROSS
NW CWA ATTM...BUT REAL COLD PUSH IS STILL BACK OVER MT PLAINS.
SYSTEM RESPONISIBLE FOR PUSHING FRONT SOUTHWARD IS MOVING THROUGH
S.MANITOBA ATTM AND HAS A TAP INTO COLD ARCTIC AIR WELL INTO THE
HIGH LATS. TEMPS IN THE UPPER 20S/LOWER 30S OVER ALTA WILL BE MOVING
TOWARD CWA AND SHOULD KEEP BELOW NORMAL TEMPS IN PLACE TONIGHT INTO
FRIDAY WITH COOL AIR TO CONTINUE TO CIRCULATE INTO EASTERN ZONES
POSSIBLY INTO SATURDAY. H2O ALSO SHOWING SYSTEM SPINNING OFF NORCAL
COAST WHICH AS IT SLOWLY PROGRESSES TOWARD COAST THROUGH
FRIDAY...WILL PUSH S/W INTO ROCKIES AND HIGH PLAINS. THIS WILL SET
UP DECENT ISENTROPIC UPGLIDE/WAA PATTERN FRIDAY NIGHT INTO SATURDAY
WITH SFC HIGH MOVING EAST INTO MIDWEST. ENERGY EJECTING OUT OF THE
WEST COAST SYSTEM WILL TOP RIDGE AND GIVE EXTRA LIFT FOR POSSIBLE
PRECIPITATION EVENT. NAM/SREF STILL WANT TO HINT AT ISOLATED
PRECIPITATION ACROSS FAR SW ZONES TONIGHT AS WEAK ENERGY MOVES OVER
ROCKIES TONIGHT AND HITS HIGH PRESSURE DOME BUILDING INTO AREA WITH
FIRST INITIAL ISENTROPIC EVENT. HAVE KEPT THE SMALL POPS AS LIFT
SHOULD GENERATE INCREASING MID CLOUD DECK THROUGH THE EARLY MORNING
HOURS. BUFKIT PROFILES INITIALLY INDICATE LOW LEVELS WILL REMAIN TOO
DRY TO GET ANYTHING TO SFC BUT EXTENDED LIFT IS SHOWN TO SATURATE
DOWNWARD BY SUNRISE AND MAY SEE A FEW LIGHT SHOWERS THROUGH MID
MORNING. THESE CLOUDS SHOULD KEEP TEMPS UP SOMEWHAT AND LIMIT FROST
POTENTIAL. ACROSS NW ZONES HOWEVER WINDS LOOK LIGHT ENOUGH AND SKY
CLEAR ENOUGH THAT FROST ADV MAY BE NEEDED ACROSS THIS AREA AND DAY
SHIFT CAN EVALUATE THREAT. CAA THROUGH THE DAY...ESPECIALLY IN NE
ZONES WILL DROP TEMPS INTO LOWER/MID 60S NORTH AND EXPECT TEMPS WILL
STRUGGLE TO GET TO 70 IN THE SOUTH. FRIDAY THE BACK EDGE OF UPPER
ENERGY LOOKS TO REINFORCE THE COLD AIR AND TEMPS WILL GENERALLY BE
IN THE LOWER 60S AND COOLER IN FAR NE. AS MENTIONED ABOVE AS THIS
SYSTEM PULLS INTO GREAT LAKES REGION...S/W RIDGE WILL BE ALLOWED TO
MOVE INTO ROCKIES AND LIFT INCREASES IN THE 305/310K SFCS AND EXPECT
MID CLOUDS TO AGAIN INCREASE OVERNIGHT...WITH FAIRLY STRONG JET
ALOFT AND LLVLS KEEPING THINGS MIXED UP ENOUGH TO PUSH LOWS BACK UP
INTO THE LOW/MID 40S. ALUETIAN ENERGY LOOKS TO DROP INTO WESTERN
STATES BY LATE WEEKEND WHICH WILL COMBINE WITH CUT OF LOW AND DEEPEN
WESTERN TROF. THIS WILL PUSH WARM AIR INTO PLAINS FOR SUNDAY INTO
MONDAY AND HAVE INCREASED TEMPS...BUT WELL BELOW GUIDANCE ATTM.

&&

.AVIATION...
THROUGH 18Z LOCALLY AREAS OF MVFR WILL TRANSLATE SOUTHWARD BEHIND A
COLD FRONT. FLIGHT CONDITIONS WILL IMPROVE NORTH TO SOUTH BEHIND THE
FRONT WITH VFR ALL AREAS AFTER 18Z.
