THE LATEST 12Z GEFS AND EURO MODEL ARE IN DECENT AGREEMENT WITH A
STRONG RIDGE STAYING IN PLACE THROUGH THE WEEKEND. THIS RIDGE WILL
ALLOW TEMPERATURES TO WARM UP INTO THE MIDDLE 80S. BY THE END OF THE

COMING OUT OF THE NORTH. MEANWHILE AT THE SURFACE, THE COLD FRONT
FROM FRIDAY IS EXPECTED TO LIFT NORTH SATURDAY AND THAN FURTHER NORTH

FLOW. SATURDAY SHOULD BE MOSTLY DRY WITH LOW-END SHOWER CHANCES
ACROSS NORTHERN PORTIONS OF THE AREA. A BETTER CHC OF SHOWERS/TSTMS
POTENTIALLY ARRIVES SUNDAY/SUNDAY NIGHT. A MORE SIGNIFICANT PATTERN
CHANGE IS LIKELY STARTING EARLY NEXT WEEK AS THE COLD FRONT FINALLY
CROSSES THE AREA WHILE A DEEP UPPER TROUGH SETTLES OVER EASTERN
NORTH AMERICA. HIGHS LIKELY DROP BACK DOWN TO NEAR SEASONAL AVERAGES
