AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
210 AM PDT MON AUG 28 2006

.SHORT TERM...
UPPER RIDGE TO FLATTEN OUT TODAY AS AN UPPER LEVEL DISTURBANCE NEAR
THE NORTHERN CALIFORNIA COAST IS KICKED INLAND BY A STRONGER TROUGH
OFF THE BRITISH COLUMBIA COAST. AS THE UPPER RIDGE FLATTENS OUT AND
WIND ALOFT INCREASE...WESTERLY AFTERNOON WINDS WILL KICK IN TODAY.
THIS WILL INCREASE CONVERGENCE/LIFT ALONG THE LEADING EDGE OF THE
WEST WINDS. THIS MAY POP OFF ISOLATED AFTERNOON THUNDERSTORMS OVER
MONO AND MINERAL COUNTIES AND FOR THE LASSEN/NORTHERN WASHOE
CONVERGENCE ZONE. TEMPERATURES WILL BE AT THEIR HIGHEST TODAY AS THE
EXITING UPPER RIDGE LEAVES BEHIND THE WARMEST TEMPERATURES ALOFT.

TUESDAY...A TROUGH SWINGS THROUGH THE PACIFIC NORTHWEST AND USHERS A
COLD FRONT INTO CENTRAL AND SOUTHEAST OREGON IN THE AFTERNOON. THIS
WILL KICK UP WINDS AHEAD OF THE FRONT TO NEAR RED FLAG CRITERIA OVER
AT LEAST THE NORTHERN HALF OF THE REGION (NORTH OF INTERSTATE 80).
THE DAYSHIFT WILL BE DETERMINING THE NECESSITY OF A RED FLAG WARNING
FOR TUESDAY. TEMPERATURE WISE...HIGHS TUESDAY WILL FALL A FEW
DEGREES FROM MONDAY AS COOLING ALOFT AND EXCELLENT MIXING CONSPIRE
TO LOWER TEMPERATURES.

WEDNESDAY WILL BRING AN ADDITIONAL FEW DEGREES OF COOLING TO THE
REGION AS THE COLD FRONT EASES INTO NORTHERN NEVADA. SNYDER

.LONG TERM...THURSDAY THROUGH SUNDAY...
AT THIS TIME NO CHANGES WERE MADE TO THE FORECAST DURING THIS TIME
FRAME. HOWEVER ONE FLY IN THE OINTMENT MAY BE EASTERLY WAVE OVER
NORTHERN MEXICO WHICH THE GFS WANTS TO CONTINUE PUSHING WESTWARD ON
SOUTHERN PERIPHERY OF UPPER RIDGE AND THEN ITS MOISTURE GETTING
PULLED NORTHEASTWARD AHEAD OF TROUGH EXTENSION LEFT BEHIND OVER THE
EAST PACIFIC. THE ECMWF IS NOT TOO DIFFERENT ALTHOUGH IT HAS HIGHER
HEIGHTS. SINCE THIS IS A SIGNIFICANT SHIFT IN THE GFS FROM 24 HOURS
AGO...WOULD LIKE TO SEE MORE PERSISTENCE BEFORE INTRODUCING SUCH A
CHANGE. WILL NOT INTRODUCE WEATHER FRIDAY THROUGH THE WEEKEND
ALTHOUGH A WEAKER TROUGH PASSAGE AT MID WEEK MIGHT SUGGEST AT LEAST
SOME LOW POPS IN THE SOUTHERN ZONES AS EFFECTS FROM WESTERLY FLOW
WOULD BE DIMINISHED AND SURFACE HEATING/CONVERGENCE MORE PRONOUNCED.
SURFACE FRONT AND NORTHEAST GRADIENT SHOULD KEEP TEMPERATURES NEAR
NORMAL THURSDAY BEFORE READINGS RISE FRIDAY INTO THE WEEKEND. HOHMANN

.AVIATION...
