NORTHWEST FLOW ALOFT WILL BE THE PREVAILING FEATURE OF THE UPPER-
LEVEL WEATHER PATTERN THIS WEEK. A CUTOFF LOW PRESSURE SYSTEM
PIVOTING FROM THE BAJA PENINSULA ACROSS NORTHERN MEXICO TODAY
WILL SHEAR OUT AND BECOME ABSORBED IN THE FLOW ALOFT, SETTING UP A
MORE TRADITIONAL POSITIVE PNA PATTERN OVER THE CONUS BY MID WEEK.
THE ANOMALOUSLY STRONG RIDGE WILL ANCHOR OVER THE WEST COAST
WHILE A TROUGH DEEPENS OVER THE EASTERN CONUS AND COMES TO
DOMINATE THE CENTRAL CONUS BY LATE WEEK. THIS FLOW WILL REINFORCE
COOLER AIR ACROSS OUR REGION THROUGHOUT THE WEEK AND PREVENT
SUBSTANTIAL MOISTURE RETURN. LIGHT RAIN IS POSSIBLE AROUND
WEDNESDAY AS THE REMNANTS OF THE CUTOFF LOW PASS THROUGH THE
REGION, BUT CONFIDENCE ISN'T HIGH FOR ACCUMULATIONS. WHILE SOME
ENSEMBLE MEMBERS HINT AT SOME POTENTIAL FOR WINTRY PRECIP AROUND
THE REGION NEXT WEEKEND, THE DETAILS DON'T SUPPORT MUCH CHANCE
FOR MEANINGFUL MOISTURE TO COINCIDE WITH AIR THAT MIGHT BE COLD
ENOUGH. NBM PROBABILISTIC DATA SUGGEST THIS MEASURABLE WINTRY
PRECIP IN OUR AREA IS STILL HIGHLY UNLIKELY. /NF/
