AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
343 AM PDT SAT MAY 5 2007

.SYNOPSIS...A LOW PRESSURE SYSTEM CENTERED OVER UTAH TODAY WILL
BRING GUSTY NORTH WINDS AND BELOW NORMAL TEMPERATURES TO THE
SOUTHERN GREAT BASIN AND MOJAVE DESERT. THERE WILL ALSO BE
ISOLATED SHOWERS WRAPPING AROUND THE BACK SIDE OF THE LOW INTO
EASTERN NEVADA AND NORTHWEST ARIZONA TODAY. THIS STORM SYSTEM WILL
MOVE INTO COLORADO SUNDAY AND MONDAY RESULTING IN DECREASING WINDS
AND A WARMING TREND.
&&

.SHORT TERM...UPPER LEVEL LOW PRESSURE WILL BE CENTERED IN UTAH
TODAY WITH A SHORTWAVE ROTATING AROUND THE BACK SIDE OF THE LOW
THROUGH NEVADA AND INTO NORTHWEST ARIZONA. MOISTURE IS LIMITED BUT
THINK THERE WILL BE JUST ENOUGH MOISTURE AND LIFT TO PRODUCE
ISOLATED SHOWERS ACROSS PORTIONS OF LINCOLN AND MOHAVE COUNTY AS
WELL AS THE SPRING MOUNTAINS AND SHEEP RANGE. OTHERWISE EXPECTING
BREEZY TO WINDY AND COOL CONDITIONS TODAY. NORTH-SOUTH ORIENTED
CHANNELS ALONG THE COLORADO RIVER SHOULD SEE WINDS REACHING LAKE
WIND ADVISORY CRITERIA AND THAT HIGHLIGHT STILL LOOKS GOOD.
MOISTURE AND SHORTWAVE ENERGY SHOULD MOVE EAST OF THE FORECAST
AREA THIS EVENING SO LOOKING FOR DRY CONDITIONS TONIGHT THROUGH
MONDAY NIGHT AS THE UPPER LOW WEAKENS AND MOVES INTO COLORADO. THE
LOW WILL NOT MOVE MUCH AFTER TONIGHT BUT WILL WEAKEN ENOUGH TO
ALLOW WINDS TO GRADUALLY DECREASE AND TEMPERATURES TO GRADUALLY
WARM UP. HIGH TEMPERATURES WILL BE ABOUT 10 DEGREES BELOW NORMAL
TODAY BUT SHOULD BE JUST ABOUT NORMAL BY MONDAY.

.LONG TERM...IMPROVING CONDITIONS IN THE EXTENDED AS LOW PRESSURE
HEADS EAST AND IS REPLACED BY HIGH PRESSURE. DID NOT MAKE ANY MAJOR
ADJUSTMENTS TO THE PREVIOUS MEDIUM RANGE FORECAST AS LIGHTER WINDS
AND WARMER TEMPERATURES STILL EXPECTED THROUGH THE END OF THE WEEK.
&&

.AVIATION...FOR KLAS: NORTH WINDS 10 TO 15 KTS AND OCCASIONALLY
GUSTY THROUGH THE MORNING HOURS. INCREASING NORTH WINDS IN THE
AFTERNOON BECOMING 15 AND 25 KTS WITH GUSTS UP TO 35 KTS. SCATTERED
CLOUDS NEAR 10K FEET POSSIBLE THROUGH THE DAY.

THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA: NORTH TO NORTHWEST WINDS 15 TO 25 KTS AREAWIDE WITH
SCATTERED CLOUDS NEAR 10K FEET. LOCALLY WINDY CONDITIONS FROM 20 TO
35 KTS ALONG THE COLORADO RIVER VALLEY DURING THE DAY.
&&

.FIRE WEATHER...STRONG NORTH WINDS DOWN THE COLORADO RIVER TODAY
WILL COMBINE WITH CONTINUED LOW RELATIVE HUMIDITY VALUES TO CREATE
CRITICAL FIRE WEATHER CONDITIONS. ISSUED A RED FLAG WARNING FOR
THOSE ZONES FOR TODAY INTO THE EVENING. A FEW OTHER ZONES IN THE
FORECAST AREA WILL BE CLOSE TO RED FLAG CONDITIONS BUT BELIEVE
EITHER RELATIVE HUMIDITY VALUES WILL BE A LITTLE TOO HIGH OR WINDS
WILL BE A TOUCH TOO WEAK.
