Severe Thunderstorm Warning 77, NWS Albuquerque, NM

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
325 PM MDT SAT JUL 29 2000

BIG PICTURE SHOWS UPPER HIGH CENTER CONTINUING TO MOVE TOWARDS UTAH
AND UPPER LOW IN MIDWEST RETROGRADING A BIT SOUTHWEST. RESULT IS A
NORTH TO NORTHEAST STEERING FLOW OVER THE FORECAST AREA THROUGH
MONDAY. THE COMBINATION OF SOME 500MB COOLING AS THE HIGH CENTER
MOVES FURTHER AWAY AND WEAK VORT MAXES ROTATING AROUND THE HIGH
SHOULD CONTINUE A TREND TOWARDS INCREASED AFTERNOON AND EARLY
NIGHTTIME CONVECTION. EASTERN PLAINS WILL BE A CHALLENGE AS UPPER
FLOW WILL KEEP STORMS AWAY AND WILL REQUIRE SOME SURFACE FEATURE FOR
A KICKER. OVERALL...ISOLATED STORMS AT BEST EASTERN PLAINS OVER THE
NEXT SEVERAL DAYS, BUT SOME DAYS WILL BE STORM FREE. BELIEVE SUNDAY
WILL BE ONE OF THOSE DAYS...AS WEAK BOUNDARY OUT THERE NOW SHOULD
MOVE FURTHER WEST TONIGHT AND REMOVE SURFACE BASED KICKER. FOR THE
CENTRAL AND WEST...PRECIP CHANCES WILL BE ALMOST ENTIRELY DEPENDENT
ON STEERING FLOW. LIKE LAST NIGHT...THINK CONVECTION WILL CONTINUE
WELL INTO THE EVENING IN A SWATH FROM THE NORTH-CENTRAL TO THE
SOUTHWEST MOUNTAINS, WITH MCS TYPE DEVELOPMENT POSSIBLE OVER THE
SOUTHWEST. WILL THEREFORE INCLUDE MENTION OF LOCALLY HEAVY RAINFALL
THERE PER EARLIER COORD WITH EPZ. WILL MENTION GUSTY EAST WINDS
THROUGH CENTRAL MTNS. AGAIN TONIGHT WITH COMBO OF WEAK SURFACE
FEATURE AND OUTFLOW FROM STORMS MOVING SOUTH OFF THE SANGRE DE CRISTO
MOUNTAINS. WON'T MESS MUCH FWC TEMPS AND WILL ADJUST POPS TO FAVOR
MOSTLY OROGRAPHICS.

EXTENDED...UPPER HIGH OVER GREAT BASIN FORECAST TO DEVELOP MORE W-E
RIDGE AXIS AS IT DRIFTS SOUTHEAST IN RESPONSE TO SYSTEM MOVING INTO
PACIFIC NORTHWEST. OVERALL...NOT ANY BIG CHANGES EXCEPT PERHAPS TO
HAVE EVEN MORE OF AN EASTERLY COMPONENT TO THE STEERING FLOW. CAN/T
RULE OUT ISOLATED CONVECTION IN THE EAST WITH ANY WEAK FRONTS OR
OUTFLOW BOUNDARIES THAT MAY BE AROUND. 42
