THROUGH EARLY NEXT WEEK...
THE SYNOPTIC PATTERN WILL BE LARGELY SUPPRESSED THROUGH THE PERIOD
AMID BROAD TROUGHING OVER EAST CONUS. THIS WILL KEEP CONDITIONS
FAIRLY DRY AND COOLER THAN NORMAL. THE EXCEPTION IS WEDNESDAY AS A
BAJA LOW EJECTS, RESULTING IN WEAK MOISTURE RETURN. THEREFORE, RAIN
CHANCES SOUTH OF I-20 AROUND 20-30%. A SERIES OF REINFORCING COLD
FRONTS MID TO LATE WEEK WILL MAINTAIN DRY AIR. CONDITIONS WILL BE
FAVORABLE FOR FREEZING/SUBFREEZING OVERNIGHT LOWS THROUGH AT LEAST
EARLY NEXT WEEK, WHICH IS BELOW NORMAL FOR THIS TIME OF YEAR. THAT
SAID, DANGEROUS COLD IS NOT ANTICIPATED FOR MUCH OF THE AREA, BUT
GTR MAY HAVE TO BE MONITORED FOR COLD HEADLINES. WILL KEEP POSTED IN
FUTURE UPDATES. WE START TO BREAK THE REGIME AROUND MID NEXT WEEK,
THE VERY END OF THE FORECAST PERIOD WITH SUBTLE HEIGHT RISES AND
RESTORATION OF SOUTHERLY FLOW. THIS SHOULD BRING LOWS BACK ABOVE
FREEZING FOR MUCH OF THE AREA, WITH THE EXCEPTION OF THE GOLDEN
TRIANGLE (LOWS IN THE UPPER 20S), BY TUESDAY NIGHT. /SAS/
