A DRY ZONAL PATTERN WILL DOMINATE OUR WEATHER THROUGH TUESDAY
NIGHT. NORTHWEST FLOW WILL BECOME MORE WESTERLY BY TUESDAY AS A
RIDGE OF HIGH PRESSURE BUILDS EAST OF THE ROCKIES. THE BEST
PRESSURE GRADIENT WILL BE OVER THE NORTHERN HALF OF THE FORECAST

AFTERNOON HOURS...ESPECIALLY OVER THE HIGHER TERRAIN. TEMPERATURES
WILL BE SLIGHTLY WARMER ON TUESDAY AFTERNOON WITH SEASONABLY WARM
TEMPERATURES. OTHERWISE...MOSTLY SUNNY/CLEAR SKIES CAN BE
EXPECTED.

THIS FORECAST AREA BEGINS IN THE CONFLICT ZONE BETWEEN THE
WESTERLIES TO OUR NORTH AND WEST...AND THE SUBTROPICAL RIDGE TO
OUR SOUTH AND EAST. BY NEXT WEEK THE WESTERLIES TAKE CONTROL.

WEDNESDAY THE WARM AND DRY CONDITIONS CONTINUE WITH THE BROAD
RIDGE EXTENDING ACROSS THE SOUTHERN TIER OF STATES WITH A TROUGH
IN THE NORTHERN ROCKIES. A RESULTING DRY SW FLOW WILL BRING THE
WARMEST DAY SINCE MID-AUGUST. TEMPERATURES MAY BE 5-10 DEGREES
ABOVE NORMAL. BREEZY AFTERNOON WINDS AND LOW RH RAISE FIRE
CONCERNS.

THURSDAY THE NORTHERN TROUGH DEEPENS TO THE SW INTO OREGON AND OFF
THE WEST COAST. IN RESPONSE A WEAK PACIFIC LOW FROM OFF THE
NORTHERN BAJA COAST GETS PULLED INLAND AND IS SHEARED APART AS IT
WORKS INTO THIS FORECAST AREA IN THE AFTERNOON. MOISTURE ALSO
ADVECTS INTO THE FORECAST AREA...DEEPEST IN SE UTAH. AMOUNTS
REMAIN MARGINAL...BETWEEN 0.9 TO 0.5 INCHES PRECIPITABLE WATER.

FOR LATE THURSDAY. SOME NOCTURNAL SHOWERS ARE EXPECTED FAVORING
THE EASTERN MOUNTAINS.

A MARGINALLY MOIST SW FLOW CONTINUES THROUGH THE WEEKEND. THE
NORTHERN TROUGH DEEPENS INTO THE GREAT BASIN EARLY NEXT WEEK
FORCING THE SUBTROPICAL RIDGE INTO THE SE STATES. TEMPERATURES
WILL STAY AROUND 5 DEGREES ABOVE NORMAL. THE NEXT EASTERN PACIFIC
TROPICAL LOW GETS PULLED INTO THE BASE OF THIS TROUGH THAT MAY
BRING ENHANCED SHOWERS BY MID-WEEK.
