AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
925 AM MST SAT MAY 28 2011

.SYNOPSIS...AN UNSEASONABLY STRONG LOW PRESSURE SYSTEM WILL MOVE DOWN
THE WEST COAST TODAY AND OVER NEVADA ON SUNDAY. THE MAIN IMPACT FROM
THIS SYSTEM WILL BE WINDY CONDITIONS TODAY AND VERY STRONG WINDS ON
SUNDAY. THERE WILL BE A SLIGHT CHANCE OF SHOWERS FROM LATE SUNDAY
INTO EARLY MONDAY ALONG WITH COOLER TEMPERATURES. EXPECT A WARMING
TREND TUESDAY THROUGH THURSDAY.

&&
.DISCUSSION...BREEZY SURFACE WINDS HAVE ALREADY PICKED UP ACROSS
MUCH OF NORTHERN ARIZONA THIS MORNING. THE MORNING SOUNDING SHOWED
50 TO 55 KT WINDS FROM ABOUT 11000 FEET MSL UP. SURFACE WINDS WILL
INCREASE THIS MORNING AND INTO EARLY AFTERNOON AS THE STRONGER WINDS
ALOFT MIX TO THE SURFACE. CURRENT WIND ADVISORY AND RED FLAG
WARNING LOOK GOOD FOR TODAY. SURFACE WINDS WILL DECREASE SOME THIS
EVENING...BUT WILL REMAIN BREEZY. SOME PASSES AND LOCATIONS NORTHEAST
OF HIGHER TERRAIN WILL REMAIN WINDY TONIGHT. THE LOW PRESSURE CENTER
WILL MOVE OVER WESTERN NEVADA BY 12Z (5 AM MST) SUNDAY INCREASING
THE WINDS OVER ARIZONA. FORECAST SOUNDINGS INDICATE THAT FREE AIR
WINDS AS HIGH AS 50KTS (58 MPH) WILL DROP TO AROUND 8500 MSL
OVERNIGHT TONIGHT AND INTO SUNDAY MORNING. THE SURFACE WINDS WILL BE
EVEN STRONGER ON SUNDAY THAN TODAY.

BOTTOM LINE...SUNDAY WILL BE ONE OF THE WINDIEST DAYS WE HAVE SEEN
ACROSS NORTHERN ARIZONA THIS SPRING. PLEASE SAY TUNED AS THIS
POTENTIALLY DANGEROUS WEATHER SITUATION DEVELOPS.

&&
.PREV DISCUSSION /245 AM MST/...AN UNSEASONABLY STRONG LOW PRESSURE
SYSTEM WILL DEVELOP ALONG THE WEST COAST AND MOVE ACROSS THE WESTERN
STATES TODAY THROUGH MONDAY. HOLIDAY TRAVELERS SHOULD BE PREPARED
FOR ADVERSE AND POTENTIALLY HAZARDOUS WEATHER THIS WEEKEND.

FOR TODAY...TEMPS WILL REMAIN NEAR SEASONABLE LEVELS. WINDS WILL
INCREASE WITH SOUTHWEST WINDS OF 20 TO 30 MPH AND GUSTS OF 40 TO 50
MPH DEVELOPING BY THE AFTERNOON.

FOR SUNDAY...THE LOW PRESSURE SYSTEM WILL MOVE ACROSS NORTHERN
CALIFORNIA AND INTO NEVADA. SFC PRESSURE GRADIENTS OVER NORTHERN
ARIZONA WILL STRENGTHEN SUBSTANTIALLY. WINDS WILL INCREASE DURING THE
DAY BECOMING SOUTHWEST 30 TO 40 MPH WITH GUSTS OF 50 TO 60 MPH OR
HIGHER. AREAS OF BLOWING DUST ARE LIKELY ACROSS EASTERN AZ. DAYTIME
TEMPS WILL COOL BY ABOUT 8 TO 12 DEGREES.

SUNDAY NIGHT...THE COLD FRONT WILL MOVE ACROSS THE AREA AND ISOLATED
TO SCATTERED SHOWERS WILL DEVELOP MAINLY ALONG THE NRN BORDER REGION
AND POSSIBLY AS FAR SOUTH AS THE MOGOLLON RIM. MODELS INDICATE ONLY
SCANT MOISTURE SO ONLY LIGHT AMOUNTS OF RAIN AND HIGH ELEVATION SNOW
IS EXPECTED. SNOW LEVELS WILL BRIEFLY FALL AS LOW AS 7000 TO 7500
FEET BY LATE SUNDAY AND EARLY MONDAY ACROSS NRN AZ. OVERNIGHT TEMPS
WILL FALL INTO THE UPPER 20S AND LOWER 30S AT ELEVATIONS ABOVE 7000
FEET WITH TEMPS IN THE UPPER 30S TO MID 40S ELSEWHERE.

BY MID WEEK...SUBSTANTIAL RIDGING WILL DEVELOP ACROSS THE SOUTHERN
PLAINS AND NRN MEXICO AND TEMPS WILL RETURN TO SEASONABLE LEVELS. AS
THE RIDGE DEVELOPS...SUBTROPICAL MOISTURE FROM THE GULF OF MEXICO
WILL PUSH NORTHWESTWARD ACROSS NEW MEXICO AND INTO EASTERN AZ
BRINGING A CHANCE OF SHOWERS...THUNDERSTORMS...AND DRY LIGHTNING.
ELSEWHERE...IT WILL REMAIN MOSTLY CLEAR AND DRY.

&&

.AVIATION...FOR THE 18Z PACKAGE...VFR CONDITIONS WILL CONTINUE FOR
THE NEXT 24 HOURS. EXPECT STRONG SOUTHWEST WINDS OF 20-30 KT WITH
GUSTS TO 40 KT THIS AFTERNOON AS A LOW PRESSURE SYSTEM APPROACHES
ARIZONA. WINDS WILL DECREASE TO 10-20 KT WITH GUSTS TO 30 KT MOST
AREAS OVERNIGHT. HOWEVER...LOCALLY STRONG WINDS GUSTING IN EXCESS OF
40 KT ARE POSSIBLE EAST OF HIGHER TERRAIN FEATURES SUCH AS THE SAN
FRANCISCO PEAKS AND KAIBAB PLATEAU. EVEN STRONGER WINDS ARE EXPECTED
ON SUNDAY. AVIATION DISCUSSION NOT UPDATED FOR AMENDMENTS.

&&

.FIRE WEATHER...FOR TODAY...STRONGER WINDS WILL DEVELOP AS A PACIFIC
LOW APPROACHES ARIZONA. A RED FLAG WARNING IS IN EFFECT FOR MUCH OF
NORTHERN ARIZONA BELOW 6500 FEET AND THE WHITE MOUNTAINS TODAY.
BREEZY WINDS WILL CONTINUE TONIGHT WITH POOR RH RECOVERY
ANTICIPATED. ON SUNDAY...EXPECT VERY STRONG WINDS WITH WIND GUSTS
EXCEEDING 50 MPH AT TIMES...ESPECIALLY FROM THE MOGOLLON RIM
NORTHWARD. COOLER TEMPERATURES AND INCREASED MOISTURE ON SUNDAY WILL
NOT BE ENOUGH TO KEEP RH VALUES AT LOWER ELEVATIONS FROM DROPPING
BELOW 15 PERCENT. AS A RESULT...A FIRE WEATHER WATCH IS IN EFFECT
DURING THE DAY FOR PORTIONS OF NORTHERN ARIZONA...PRIMARILY BELOW
6000 FEET. SUNDAY NIGHT...THE UPPER LOW WILL CROSS THE
STATE...BRINGING A SLIGHT CHANCE OF SHOWERS TO THE HIGHER TERRAIN
NORTH OF INTERSTATE 40.

FOR MONDAY THROUGH WEDNESDAY...THE WEEKEND LOW PRESSURE SYSTEM WILL
HEAD EASTWARD. HIGH PRESSURE WILL THEN BEGIN TO BUILD OVER TEXAS
WHILE ANOTHER LOW PRESSURE SYSTEM DEVELOPS OFF THE WEST COAST. THE
MAIN IMPACT OF THIS PATTERN SHIFT THROUGH WEDNESDAY WILL BE
INCREASING DAYTIME TEMPERATURES AND LOWERING RELATIVE HUMIDITY
VALUES. WINDS WILL BE LIGHTER ON MONDAY...BUT AS THE PRESSURE
SYSTEMS DEVELOP...SOUTH TO SOUTHWEST WINDS WILL BE ON THE INCREASE
TUESDAY AND WEDNESDAY. ENOUGH MID-LEVEL MOISTURE COULD MOVE IN BY
WEDNESDAY FOR A SLIGHT CHANCE OF SHOWERS OVER THE WHITE MOUNTAINS.
