VALID 12Z MON MAR 09 2015 - 12Z FRI MAR 13 2015


THE FLOW PATTERN ACROSS THE UNITED STATES IS EVOLVING ONCE AGAIN,
WITH THE COLD TAP INTO THE EAST RELAXING, ALONG WITH A TENDENCY
TOWARD SPRINGLIKE CLOSED LOWS. THE POSITION OF CLOSED LOWS IS
ALWAYS A TOUGH CALL FOR THE MODELS, SO RELIED ON THE ENSEMBLE
MEANS TO MITIGATE ERROR. THE FIRST CLOSED LOW IS EXPECTED OVER THE
WESTERN GULF OF MEXICO, WITH RAINS ALONG AN OLD FRONTAL BOUNDARY
ACROSS THE SOUTHEAST GRADUALLY RETROGRESSING BACK TO THE LOWER
MISSISSIPPI AND TENNESSEE VALLEYS. THE SECOND CLOSED LOW IS
EXPECTED TO PROGRESS ACROSS THE EASTERN PACIFIC OCEAN AND INTO THE
WEST COAST. THIS SYSTEM SHOULD BE ACCOMPANIED BY A SIGNIFICANT
UPTICK IN PRECIPITATION FROM SAN FRANCISCO NORTHWARD LATE NEXT
WEEK.
